How Solar PV Systems Work

Generating electricity using solar electric panels and associated equipment

How Solar PV Panels Generate Electricity

Solar photovoltaic (PV) panels use cells containing a semi-conductor material to capture the sun’s energy and convert solar radiation into electricity. The most commonly used semi-conductor material is silicon, which is an abundant natural resource found in sand. When light strikes the cell a certain amount of energy is absorbed within the semiconductor material, knocking electrons, the negatively charged particles that form the basis of electricity, loose.

Most PV cells have two layers of semi-conductor material, one positively charged and one negatively charged. When light shines on the semi-conductor the electric field across the junction between these two layers causes electricity to flow, generating direct current (DC). By placing metal contacts on the top and bottom of the PV cell, we can draw that current off for external use.

Solar PV electric panels do not require bright sunlight in order to operate, meaning that you can still generate electricity on cloudy days, however in general the greater the intensity of light the higher the flow of electricity. Although,  due to the reflection of sunlight, days with slight cloud can result in higher energy yields than days with a completely cloudless sky.

It is important to realise that you can only use your free solar electricity when it is being generated – so unless you also invest in batteries to store power for use in the evenings and at night, you will need to pay for your energy use as normal when the panels are not producing electric.

How the Electricity is Converted for use

Direct Current (DC) needs to be converted into alternating current (AC) so it can be used in a domestic building; this is performed by an inverter. The AC electricity then passes via the generation meter, which measures how much electricity has been created, and on to the consumer unit where it can be fed into the property for use or exported back to the national grid via the electricity meter.

A typical grid connected roof mounted system consists of a number of components, as shown in the diagram to the right.

You will be paid for every kWh of electricity that your solar PV system generates, even if you use the power yourself. You will also be paid an additional amount for any electricity that you export to the national grid. Click here to visit the feed in tariff page to find out more.

    Cyprus Set To Launch ‘Photovoltaics For All’

    Exciting news for all homeowners!

    “Photovoltaics for All” is a program, making it simpler and more affordable to have rooftop solar panels.

    This new program is part of the government’s efforts to help people in need. It’s aimed at giving everyone access to the benefits of solar power, without the big upfront costs.

    In a bold move to expedite the transition to green energy, the Ministry of Energy is gearing up to unveil a groundbreaking solar energy production initiative that promises to reshape the balance between conventional and green energy sources.

    Under the banner of “Photovoltaics for All,” the government’s ambitious plan seeks to lower electricity tariffs while boosting the adoption of renewable energy sources (RES).

    Notably, this project distinguishes itself from past endeavors by eliminating restrictions on the number of beneficiaries. This means that any interested individual can apply for the installation of photovoltaic panels on their roof for self-consumption without the need for an initial capital investment. Moreover, users can anticipate a 50% reduction in their electricity bills once the system is operational.

    No Bank Loans Needed

    You won’t need to get a bank loan to make this happen. The money for the project comes from the Renewable Energy Sources and Energy Conservation Fund. They will cover the cost of buying and installing the solar panels.

    How It Works

    Once the solar panels are up and running, you will start paying for them through your electricity bill from the AHK or another electricity company. This payment is about €150 every two months. But don’t worry, you will save more on your electricity bill, thanks to the solar panels.

    The Five-Step Process

    The “Photovoltaics for All” project aims to streamline the installation process, with bureaucratic procedures and system setup estimated to be completed within three months of application. Here are the five essential steps to install a photovoltaic system in your home:

    -Application (anticipated start date: January 1, 2024).
    -Installation approval.
    -Sponsorship payment (options of €1000 or €1500).
    -Photovoltaic panel installation.
    -Connection to the grid.

    Notably, recent data suggests a significant reduction in delays for RES generation connections, with the number of pending requests dropping from 1000 to below 100.

    Who Can Benefit?

    The “Photovoltaics for All” plan is designed to cater to a wide audience, particularly targeting small and medium-sized homes. Prospective beneficiaries can choose between two grant options: €1000 and €1500. Under the €1000 grant, applicants are not required to make an initial capital investment for the photovoltaic installation, and the maximum solar energy production is capped at 4.5 kW.

    Repayment will occur through installments (€150 on each electricity bill) over three years. On the other hand, the €1500 grant mandates a one-time installation payment, while there is no restriction on solar energy production.

    Funding for this initiative will come from the RES and Energy Saving Fund (RES – ex.(E)), which is bolstered by European funds dedicated to green initiatives. Additionally, resources from the emissions fund may also be utilized, creating a continuous cycle of funds flowing to consumers for green energy production and repaid in installments to the fund.

    Immediate Benefits

    The advantages of this project will become evident as soon as the photovoltaic system goes live. Those opting for the €1000 sponsorship option can expect their electricity bills to be halved. For instance, with an average consumption of €370, consumers will pay only €30 every two months for fixed charges, in addition to the €150 repayment installment for the photovoltaic system—amounting to a total of €180.

    Overall, it’s estimated that the investment in a residential photovoltaic system in Cyprus will be amortized in approximately five years, taking into account the RES and ex Fund.E sponsorship (or six years without sponsorship). It’s worth noting that the lifespan of a photovoltaic system exceeds 20 years.

    Network Modernization

    The “Photovoltaics for All” plan is poised to drive the modernization and enhancement of the electricity transmission and distribution network. Recognizing that the existing infrastructure is outdated and in need of an upgrade, the Energy Minister has initiated a redesign process aimed at transforming it into a “smart” grid, increasing electricity capacity.

    Additionally, the grid will be equipped with battery meters to facilitate energy storage, primarily for nighttime use. Consultations regarding the bolstering of the network with batteries have concluded, and installation is set to commence within the next two years. However, it’s acknowledged that the full upgrade will coincide with the launch of solar energy production under the “Photovoltaics for All” project.

        7 Affordable, Stylish Gunite Pool Features to Consider

        Are you planning a gunite swimming pool and want beauty and functionality—without busting your project budget? The good news is that an affordable gunite pool can have style and personality too. While the sky’s the limit on how much you can spend customizing a gunite design, no one has to. A number of features are not only attractive and functional, but reasonably priced. As you research inground pool prices, here are seven features to consider. Every one of them will add visual intrigue and pleasing aesthetics to any aquatic resort. The final cost of each will depend on the size, style, quantity, and local pricing in your local market.

        1. Multicolor LED Lighting

        One low-cost, “brilliant” idea for enhancing your pool’s appearance relates to how you illuminate it. In recent years, the advent of LED pool lights has been a game-changer. Using light-emitting diodes, this technology transforms any pool with an array of vibrant colors each evening. With the touch of a button, you can “paint” your pool & spa in a single color—not only white and blue, but in green, gold, pink, or purple. For even more drama, set the LEDs to rotate through a spectrum of colors. But for the ultimate in scenery and ambiance, go for an LED “light show.” Preset, themed programs such as “Gemstone,” “Tranquility,” and “Cool Cabaret” cycle in hundreds of colors that flash and dance around your pool at various speeds. As a bonus, LEDs cost less to maintain than old-school incandescent pool lights. LEDs are incredibly energy-efficient, and they will ensure many years of dazzling performance.

        2. A Bubbler—or Two or Three

        Add a dash of frothy bling to your pool water. Bubbler fountains bring motion and interest to your aquatic retreat even when it’s not in use. Entertaining poolside? Just switch on your bubbler fountains for a lovely, soothing sight. Bubblers can go into a pool’s top step. But by far, the favorite location is a tanning ledge. Accenting the shallow ledge with one, two, or three of these fountains not only looks great, it provides a visual cue to recognize the ledge’s shallow depth. Bubblers are trending more than ever when it comes to modern pool design. With a low price point, these fountains can fit into most gunite pool budgets. The playful feature is priced low enough that you can add a pair or trio of them to enjoy. Splurge a little, and you can add LEDs to light them up when the sun goes down.

        3. Cascade Water Features

        For some splashy spirit, include one or more cascade water falls on your pool. These affordable fixtures emanate a small, continuous sheet of water that flows into the pool below. The plumbed fixture mounts to the pool’s “bond beam.” Bond beam is a section of pool wall that extends at least 6 inches above the pool. On the shortest bond beam—just half a foot—it’s possible to include one special kind. This particular style produces an arcing cascade. The water moves upward and out before falling onto the pool’s surface. However, the two other kinds are used far more frequently. One has a sheet that descends straight down in a sleek fashion.

        The other kind produces a sheet that arcs; it travels several inches or more outward and over the pool before hitting the surface. To accommodate one of these common versions, the bond beam must be at least one foot high. The final cascade effect will be even better if the beam is 18 to 24 inches high. When it comes to width, most cascades run 12 to 18 inches. Custom versions span several feet. Although a single cascade looks great, many pool buyers prefer two or three mounted at set intervals across the bond beam. Most cascades will produce flat, sheer sheets of water. Their smooth surface will catch the sunlight and make them virtually shine. For a different cascade look, a broken “raindrop” style is also available.

        4. Umbrella Via Sleeve

        Bring comfortable shade and a bright pop of color to your pool area. Integrating a sleeve to hold an umbrella pole is a simple, effective way to make both possible. During construction, your builder can incorporate a hidden sleeve. Later, when your pool’s complete, pop in the patio parasol of your choice. Since the sleeve is always present, it’s easy to add or remove the umbrella as you wish. You can request one or more umbrella sleeves in various spots around your pool or spa. For example, the sleeve can be inserted into the pool coping around the spa. There, an umbrella can block some of the sun’s rays while you hang out in the bubbling water. However, the hands-down favorite approach is for sleeves to go into tanning ledges. Pool owners appreciate having an umbrella on the ledge for some sun protection. An umbrella sleeve is a genuine bargain. Once the sleeve is ready, buy a patio umbrella in any price range you like. Now you have a colorful, stylish, convenient way to beat the heat for minimal cost.

        5. Raise the Spa

        If you are already planning a gunite spa with your new pool, take it—literally—to the next level. Building a spa even just 6 inches above the pool will draw more attention. Raise the spa 12 to 18 inches, and it transforms into a bolder focal point. This added height enhances the spa’s aesthetics. Here’s how: As spa water overflows down a foot or more to the pool surface below, the spillway creates an attractive “water-in-transit” effect. As a bonus, some spillover designs generate soft gushing sounds as they hit the pool surface. But again, these wonderful effects are not possible with a spa that’s level with the pool or raised a mere 6 inches. A spa that’s at least a foot above the pool boasts another decorative treat: The spa will reveal its upper dam wall—the barrier that separates the spa water from the pool water. This section of exposed spa dam wall becomes a backdrop for showcasing colorful pool tile, specially arranged tile patterns, or decorative stone. Elevating your spa may also elevate your backyard experience. As you relax in the hot bubbling water, the higher perch provides a better view. From the comfort of your raised spa, you will enjoy the views across your pool surface, surrounding landscape, and any distant vistas.

        6. Jets on Deck

        How about some liquid “eye candy” along with an aural ambiance that your ears will appreciate? With deck jets, you will relax watching graceful streams gently hit your pool’s surface. These moving arcs glisten in the sunshine as their spray falls onto the water below. With several on a pool, you may hear lovely sounds as well. Pool deck jets project several feet upward, and some can go taller. As the emanating arc descends, the tubular shape diffuses and spreads into small droplets. Whether they accent a chic geometric pool, classic Roman/Grecian, curvy tropical lagoon, or any other pool style or pool shape you pick, deck jets will bring extra motion and character to the setting. Best of all, deck jets can be had for surprisingly little. With an economical price point, you can introduce one or more of these playful features into your pool and deck design.

        Note: Avoid confusion between the modest deck jet and its high-cost cousin: a laminar. Equipped with its own motor, a laminar emits a highly uniform, glass-like arc. This pricier option can also be internally illuminated with LEDs.

        7. Ready-made mosaics

        If the Greeks and Romans could enjoy the beauty of mosaics, so can you! Now, handcrafted tile mosaics rank on the list of stunning, expensive pool features. It’s true, “custom” mosaics are essentially original works of art that command big price tags. However, you can achieve some of the looks of fancy mosaics—for a fraction of the cost. Many off-the-shelf mosaics are available for a gunite pool’s floor, walls, ledges, benches, and steps. These versions are easy on your wallet and come in colorful, whimsical, and sophisticated designs. The wide assortment of standard images will make choosing your pool mosaic big-time fun. Sea creatures such as fish, crabs, turtles, and dolphins are among the most popular.

            Daikin Europe Lifts Patents On R32 in VRF Systems

            Brussels, 1 July 2022 – Daikin Europe N.V. released its ‘HFC-32 PATENT NON-ASSERTION PLEDGE’ which will provide free access for the entire market to Daikin Europe’s 30 patents related to VRF systems combined with HFC-32 (R32) refrigerant. Providing this free access will further promote the use of the non-blended, single-component HFC-32 refrigerant in VRF systems, which has a lower global warming impact than R410A, the refrigerant conventionally used in VRF systems.

            The decision of Daikin to provide free access to its patents happens against the background of global attempts to reduce the impacts of HFCs on global warming, especially now that the Kigali Amendment to the Montreal Protocol*1 is being translated into actual country regulations. For the European Union, the European Commission is currently considering an update of the existing F-Gas Regulation, which might result in stricter requirements for the use of refrigerants. Also VRF systems will be subject to the new regulation, if it comes into effect. VRF systems heat and cool large buildings such as offices, schools, hospitals and so on. To do this, multiple indoor units are connected to a single outdoor unit, and a closed refrigerant circuit flexibly moves through the system, allowing individual temperature control throughout the rooms of a building. The HFC refrigerant conventionally used in VRF systems is R410A.

            The F-Gas regulation will force air conditioning and heating manufacturers to choose a refrigerant with a lower GWP. HFC-32 can provide a VRF solution with such a lower GWP refrigerant. This is where free access to Daikin’s patents can accelerate the adoption of HFC-32.

            Mechanical Installations

            ‘Daikin comprehensively evaluates a wide variety of refrigerants and promotes the selection of the appropriate refrigerant for each application, and currently considers HFC-32 to be the most suitable refrigerant for VRF systems.’, says Martin Dieryckx, General Manager Environmental Research Center. ‘HFC-32 has many advantages that can help reduce the environmental impact of air-conditioning. HFC-32 is a non-ozone depleting refrigerant and its GWP is one-third*2 of conventional R410A refrigerant. It provides excellent system performance and is readily available. As a single-component refrigerant, it is easy to recover, recycle and reclaim, which reduces the need for additional production of virgin refrigerant.’

            Kazuhide Mizutani, General manager of EMEA Research Center, says ‘The patents that Daikin Europe pledged not to assert include those relating to the control of compressor rotation speed and safety systems such as refrigerant leakage sensors. The Pledge will make it easier for other air conditioning and heating manufacturers to develop VRF systems using HFC-32. Furthermore, promoting the installation of safety systems in equipment reduces the burden on air-conditioning installers to inspect equipment.’

            Daikin Industries, the mother company of Daikin Europe, has pledged the non-assertion of the patents in relation to applicable air conditioning equipment using HFC-32 from 2019 in order to contribute to the environment. Apart from Daikin Europe’s patents,  the company simultaneously pledged today the non-assertion of the new 90 patents. Daikin Group aims to make further environmental contributions worldwide. A list of the pledged patents and the specifics regarding the pledge is available here.

              Sponsorship Plan for installation of photovoltaics and thermal insulation of roofs in houses

              The budget of the Sponsorship Plan for the installation of photovoltaics and thermal insulation of houses in the houses for the years 2022-2023 is increased to € 30 million, with the application process starting today and remaining in force until 20/12/2023 or until exhaustion of the budget, whichever comes first.

              The doubling of the budget compared to previous years was decided within the framework of the government package of measures to relieve the citizens from the inflationary pressures. It is estimated that more than 10,000 applicants will benefit from the sponsorship, which, by making the relevant investments, will significantly reduce their energy costs.

              In addition to doubling the budget, the Plan is announced this year with significant increases in sponsorships compared to the Plans implemented in previous years, with the aim of even greater support for citizens. Specifically, the grants are increased by 50%. An important difference is the introduction of virtual metering (Virtual Net Metering), for consumers who can not, due to technical limitations, install photovoltaic systems on the roofs of their homes.

              The Plan will cover the following categories of investments:

              CATEGORY 1 : Thermal insulation of roofs of existing houses. A sponsorship of 45% of the eligible costs of each application / residence is provided, with a maximum sponsorship amount per application of € 2,250. For the residents of mountain communities the amounts increase by 50%.

              CATEGORY 2: Thermal insulation of roofs of existing houses in combination with the installation of a photovoltaic system with the method of offset measurements (Net Metering or Virtual Net Metering). A sponsorship of 55% of the eligible costs for the thermal insulation of the roof is provided, with a maximum sponsorship amount of € 2,750 and funding of € 450 per installed kW photovoltaic system, with a maximum sponsorship amount of € 1,800. The maximum amount of sponsorship per application can reach € 4,550. For the residents of mountain communities the amounts increase by 50%.

              CATEGORY 3: Installation of photovoltaic system by the method of metering offset (Net Metering) or virtual metering offset (Virtual Net Metering) in existing homes. The amount of the sponsorship amounts to € 375 per installed kW photovoltaic system, with a maximum sponsorship amount of € 1,500 ( CATEGORY 3A ). For the residents of mountain communities the amounts increase by 50%. The amount increases to € 1,000 per installed kW of photovoltaics for the homes of vulnerable consumers, with a maximum sponsorship amount of € 5,000 ( CATEGORY 3B ).

              Existing residences are eligible, for which the application for a building permit or urban planning permit has been submitted:

              – for CATEGORIES 1 and 2 before 21/12/2007.

              – for CATEGORIES 3A and 3B before 01/01/2017.

              The Plan has retroactive effect to ensure the smooth continuation of the previous Plan of 2021. Therefore, investments made after 01/08/2021 are eligible. Investments made before 01/08/2021, are not eligible.

              All information about the Plan, including the Plan Guide and the application process, can be found on the RES and FDI Fund

                The Perfect Climate For A Good Night’s Sleep

                Have you ever woken up with a dry mouth and a sore throat? Humidity levels in your bedroom are likely to have fallen below the internationally accepted threshold for a healthy indoor climate. But what exactly is the threshold? And how do you create the perfect atmosphere for a good night’s sleep?

                Why does humidity matter?

                Humidity is the concentration of water vapor in the air. The humidity level in your home can affect your personal health in many ways. Excessively high humidity, for example, is associated with higher concentrations of allergens, while exposure to excessively low humidity can cause health problems such as dry skin, itchy eyes and sore throat. Maintaining healthy humidity levels is important to make the bedroom a comfortable space and ensures a healthy sleep cycle for rejuvenation.

                How can I ensure the perfect climate?

                Humidity levels are usually measured by the relative humidity which is the ratio of water vapor in the air to the amount of vapor that can be present in the air at a given temperature. The best relative humidity for sleep has been a topic of discussion but most studies agree that the best indoor relative humidity is between 40 and 60%. If you usually wake up with a sore throat and dry eyes, the relative humidity level in your bedroom may have dropped well below the 40% threshold.

                Ensuring a perfect indoor climate can be a challenge. In climates with extremely high humidity levels, it is a good idea to install an air conditioning system with a built-in dehumidifier . These systems automatically detect values ​​that exceed the preferred humidity level (usually starting at 60 ° C) and extract moisture from the air to achieve healthy humidity levels.

                For extremely low humidity levels, installing an air purifier with a built-in humidifier can help achieve a healthier, more comfortable indoor climate. For example the ionizer with Daikin humidification function, injects moisture into the air when the relative humidity falls below the preferred level (usually starting at 40%) to maintain a healthy humidity level. Daikin air purifiers also minimize asthma and allergy symptoms by removing dust particles and pollen from the air, and Streamer technology keeps the air healthy and clean by eliminating allergens, eliminating bacteria and removing odors. This cleaning element separates ionizers with a humidification function from traditional humidifiers as traditional humidifiers tend to accumulate pollutants instead of eliminating them, allowing them to continue to reproduce and possibly cause disease. And what about the noise? The Daikin humidifier with built-in humidifier is extremely quiet thanks to a new innovative device and a state-of-the-art quiet operation, making it one of the quietest series of air purifiers on the European market. The perfect solution for a good night’s sleep while at the same time staying healthy, refreshed and feeling comfortable.

                  Daikin Altherma 3 H HT is an investment in comfort and energy savings. This air-to-water heat pump delivers heating, cooling and instant hot water—and uses less energy to do it. This system is ideal for homeowners who want to upgrade their boiler or traditional heating system to a greener and more cost-effective solution.

                  Ideal to replace oil boilers

                  Daikin Altherma 3 H HT is a high temperature heat pump, able to deliver a leaving water temperature of 70 °C. Thanks to this operation range, the unit can replace oil boilers in older houses. Traditional radiators can also stay in place, but more recent radiators could be a good option in order to make further energy savings.

                   

                  Suitable for large new buildings. With a capacity range going from 14 to 18 class, Daikin Altherma 3 H HT can answer the needs of large new buildings.

                  Made in Europe, for Europe

                  European weather can be tough sometimes. That’s why we designed the Daikin Altherma 3 H MT & HT.

                  Heating capacities are also maintained high by low ambient temperature thanks to genuine Daikin technology.

                  As the market leader, Daikin is always striving to make the most reliable and efficient heat pumps possible. Daikin developed the Bluevolution technology to achieve higher and greener performance. This technology is now part of all new products. The Daikin Altherma 3 H HT was the first Daikin outdoor unit with a distinctive design. Its single fan reduces the noise level and its black front grillemakes the unit fit into any environment. All these dedicated components were developed in-house to make the quintessence of heat pump unique.

                  Superior performance, renewable energy use, design and acoustic comfort.

                  Timeless design and space-saving installation

                  Aside from the acoustic comfort, design is a decisive point nowadays. Specific attention was paid to making the outdoor unit blend in with your home. The black front grille stretches horizontally making the fan inside invisible.

                  The mat grey casing reflects the colour of the wall behind for more discretion. This unit received the IF and reddot design awards 2019. The Bluevolution technology combines a specifically developed compressor and the R-32 refrigerant. Daikin is one of the pioneers in the world to launch heat pumps equipped with R-32. With a lower Global Warming Potential (GWP), the R-32 is equivalent in power to standard refrigerants, but achieves higher energy efficiency and lower CO2 emissions. Easy to recover and re-use, R-32 is the perfect solution to attain the new European CO2 emission targets.

                  Silence rhymes with comfort

                  The Quintessence of heat pump has been designed to reduce its acoustic level and meet the expectations of today’s society. In standard sound mode, the unit produces a sound pressure of 38 dBA at 3 metres, so somewhere between birds chirping and the inside of a library. The unit also offers greater flexibility by having a low sound mode that reduces the sound pressure at 3 metres to 35 dBA, representing a real reduction of half the sound level!

                  The acoustic level can be evaluated in two ways

                  › The sound power is generated by the unit itself, independently of distance and environment

                  › The sound pressure is the sound perceived at a certain distance. The sound pressure is usually calculated at between 1 and 5 metres from the unit.

                  One solution, multiple combinations

                  The Quintessence range can be combined with three different indoor units to connect to the outdoor unit, offering specific features to ensure heating, cooling and domestic hot water in your home.

                  Outdoor unit

                  The outdoor unit is available in 6 classes 8-10-12-14-16-18 kW.

                    11 Steps For A Summer-Ready Pool

                    How to open up your pool after the winter

                    1. Remove cover

                    • Wind up the pool cover carefully ensuring as few leaves and debris enter the pool as possible.

                    Mechanical engineering cyprus2. Clean the cover

                    • Place the cover flat side up with the bubbles facing down.
                    • If possible use the space available around the pool by setting the reel system back, creating a flat surface between the reel and pool.
                    • Your cover can also be laid out on a lawn to be cleaned.
                    • Rinse down with a hose or jet washer (ensure jet washer kept 20cm – 30cm from cover).
                    • Use a soft brush to remove embedded residue.

                    3.Clear the pool of debris

                    • Use deep net or skimmer net to clear leaves and debris from surface and floor of the pool.
                    • Open and empty skimmer baskets, clean inside of skimmer.

                    4. Deep clean the pool

                    5. Top up water levels

                    • Run hose line to the pool and bring the water level to the middle of the skimmer.

                    6. Set up the filter

                    • Ensure pump is switched off and turn off inlets, main drain, and skimmer valves to pump and filter.
                    • Open the lid to the pump remove the pump filter basket.
                    • Clean the pump filter basket and reinstall.
                    • Ensure the pump seal is clean and reinstall.
                    • Use a bucket of water to help prime pump. Replace pump lid.
                    • Open inlets, main drain, and skimmer valves to pump and filter.
                    • Switch on pump for 24 hours, ensuring the multi-port valve is set to “filtration”
                    • Backwash the pool filtration as required.

                    7. Check chemical levels and balance pool

                    • Take water samples from the pool (ensure taken 20cm under the water level).
                    • Check pH, Free Chlorine (FC), Combined Chlorine (CC), (calculate Total Chlorine (TC)), Calcium Hardness (CH) and Total Alkalinity (TA).
                    • Take appropriate actions to balance pH, CH and TA (take time to allow chemicals to settle).
                    • Add stabilised chlorine to level the pool between 2-4ppm.
                    • Allow to settle and recheck chemical levels

                    8. Shock the pool (if required)

                    • Put on PPE and weigh out shock chlorine.
                    • Fill bucket with warm water.
                    • Add the required shock to the bucket slowly.
                    • Stir until dissolved.
                    • Add shock slowly to the pool moving around the pool and ensuring not to splash and to pay attention around the skimmer.
                    • Ensure all pool equipment is cleaned thoroughly.
                    • Leave and allow the shock to do its work.
                    • Repeat as needed.
                    • Ensure the pool cover is off the pool water until the free chlorine level has returned to 2 – 4 ppm

                    9. Reinstall the cover

                    • When the chemical levels have returned to industry standards, reattach cover to reel and install on pool.

                    10. Set the pump and filtration timings

                    • Check the inlet nozzles are set to provide the best possible circulation.
                    • Set the filtration time schedule ensuring enough time to completely circulate the pool.
                    • For best heating performance set filtration to turn during the sunlight hours between 11 and 4.

                     

                    11. Check, check and Recheck

                    • Recheck pH, FC, CC ,TC and make adjustments if required.
