Installation Installation items The factory only provides the heat pump unit. Other necessary items, according to the illustration are to be provided by the user or installer. Attention! Please follow according to the following steps whilst installing the heat pump: The chemicals have to be added downstream of the heat pump. It is recommended to install a bypass when the flow of the pool pump is more than 20% of the rated flow of the heat pump. Install the heat pump on a solid foundation and use the damping rubbers to eliminate vibrations and noise. Keep the unit straight up at all times. When the unit has been tilted, it is required to wait 24 hours before re-starting the heat pump. Location The unit may be installed practically anywhere outdoors. DO NOT put the unit in an enclosed area with a limited air volume where the unit discharge air will be re-circulated. DO NOT put the unit next to shrubs. This may block the air inlet. Such locations deny a continuous source of fresh air, which reduces its efficiency and may prevent adequate heat delivery. The picture below give the minimum required distances from each side of the heat pump: 5
Distance Install the heat pump as close to the swimming pool as possible to minimize the loss of heat through the piping. Put it on a solid base and place the rubber blocks under the heat pump to eliminate vibrations. Normally, the heat pump is installed within a 7,5 meter radius of the pool. Heat loss is minimal up to distances of 30 meters. The heat loss per 30 meters is estimated at 0.6kw/hour for every 5 C difference between the pool water and surrounding of the pipe. This increases the operation time around 3-5%. Installation of the valve Attention! Placement of the chlorinator, water balance equipment, and the placement of injectors of chemicals, are very important aspects of the installation. All addition of chemicals have to be done downstream from the heat pump. Failure to protect the heat pump unit from chemical damage is not covered under the warranty. 6
Installation of the pool system Installation of the bypass With the bypass set correctly, your heat pump will deliver its best performance. The bypass has to be built as show below: Setting the valves of the by-pass: Set all 3 valves entirely open Slightly close valve 1 Close valve 3 about half way to adjust the refrigerant pressure 7
Electrical wiring Attention! Verify the local power supply and the operating voltage of the heat pump. It is recommended to use a separate circuit breaker (slow type D curve) for the heat pump together with the proper wiring characteristics. The current to the heat pump should only be applied when the filter pump is running. For example, a relay controlled by the filter pump could be used to activate the current to the heat pump. Connect the electrical supply to the junction box inside the unit. All heat pumps require single-phase connection. Grounding the heat pump is required to protect you against electrical shocks caused by an eventual short circuit inside the unit. The heat pump is not equipped with a flow switch or any other kind of water flow detection. Therefore, the heat pump has to be wired electrically together with the filter pump to ensure water flow while the heat pump is running. Please consult the Appendix for more information. Start-up procedure Start-up Procedure - after the installation is completed, you should follow these steps: 1. Turn on your filter pump. Check for water leaks and verify the flow to and from the pool. 2. Turn on the electrical power supply to the unit and turn the unit ON with the switch. The unit will start after the time delay period has lapsed. 3. After running a few minutes, check whether the air leaving the side of the unit cooled down. 4. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is reached. When the set temperature is reached, the unit just shuts off. The unit will now automatically restart (as long as your pool pump is running) when the pool temperature drops more than 1 degree Celsius below set temperature. Several days are needed to bring the temperature of you swimming pool water to its required value. Water flow switch- The unit is equipped with a flow switch that switches on when enough water has flowed through the unit and vice versa. Time Delay - the unit is equipped with a 3-minute built-in delay to protect the control circuit components and to eliminate restart cycling and contactor chatter. This time delay will automatically restart the unit approximately 3 minutes after each circuit interruption. Even a brief power interruption will activate this delay and prevent the unit from starting until the 3-minute countdown is completed. Condensing Since the Heat pump cools down the air about 8-12 C, causing condense on the fins of the evaporator. If the relative humidity is very high, this could be as much as several liters an hour. Sometimes this condensation water is misjudges and considered a leakage. 8
Guidelines Water chemistry Special care should be taken to keep the chemical balance of your swimming pool within limits: ph 7,0 7,4 Free chlorine 0,5 1,2 mg/l TAC 80 150 mg/l (10 F 30 F) Salt max 3 g/l Attention! Failure to keep the swimming pool water between above limits will void the warranty When the concentration of one or more products mentioned above becomes too high, irrevocable damage to your heat pump may occur. Make sure that you always install water treatment equipment after the heat pump. When an automatic chemical feeder is installed in the plumbing, it must be installed downstream of the heat pump. A check-valve must be installed between the heat pump and the chemical feeder to prevent backsiphoning of chemically saturated water into the heat pump where it will damage the components. Winter-ready Attention! Failure to winterize could cause damage to the heat pump and will void warranty In areas where freezing temperatures occur, you should protect your pump, filter and heat pump from the elements. Perform the following steps to completely drain the heat pump: 1. Turn off the electrical power to the heat pump at the main breaker panel. 2. Shut off the water supply to the heat pump: close valves 2 and 3 on the by-pass completely. 3. Disconnect the water inlet and outlet and let the water drain from the heat pump. 9
Spring start-up If your heat pump has been made winter-ready, perform the following steps whilst starting the system in the spring: 1. Inspect the system for any debris or structural problems. 2. Connect the water inlet and outlet unions firmly. 3. Turn on the filter pump to supply water to the heat pump. Adjust the by-pass to allow water flow through the heat pump. 4. Turn on the electrical power to the heat pump at the main breaker panel. Owner inspection The ECO heat pumps are designed and constructed to provide long performance life when installed and operated properly under normal conditions. Periodic inspections are important to keep your heat pump running safely and efficiently through the years. The following basic guidelines are suggested for your inspection: 1. Make sure the front of the unit is accessible for future service. 2. Keep the surrounding areas of the heat pump clear of all debris. 3. Keep all plants and shrubs trimmed and away from the heat pump. 4. Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage. Use a deflector if needed. 5. If the unit is installed under a very sharp roof pitch or under a roof without a gutter, a gutter or diverter should be fitted to prevent excessive water from pouring down onto the unit. 6. Do not use the heat pump if any part has been under water. Immediately call a qualified professional technician to inspect the heat pump and replace any part of the control system, which has been submerged. The heat pump will produce condensation (water) while in operation. The heat pump base is designed to allow the condensation to exit through the bottom drain port. The condensation will increase as the outdoor air humidity level increases. Check the following at regular intervals to ensure proper condensate drainage: 1. Visually inspect and clear the bottom drain port of any debris that could clog the port. 2. Keep the air intake area and discharge area clear of debris so the airflow through the heat pump is not restricted. The cooler discharge air should not accumulate and be drawn into the side air intake coils. During normal operation, the heat pump produces ten to twenty liters of condensate per hour. If condensate drainage is above this range during operation or if water continues to drain from the base when the heat pump is not in operation for more than an hour, a leak in the internal plumbing may have occurred. Call a qualified heat pump technician to investigate the problem. Attention! A quick way to verify that the water running through the drain is condensation water is to shut off the unit and keep the pool pump running. If the water stops running out of the base pan, it is condensation water. 10
