Installation Installation items The factory only provides the heat pump unit; the other items that are mentioned in the illustration are to be provided by the user or installer. Attention! ○ All feeding of chemicals to the pool water has to be done downstream of the heat pump.
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. Installation of the valve The placement of the chlorinator, water balance equipment, and the placement of injectors of chemicals, are very important aspects of the installation.
Installation of the bypass With the bypass set correctly, your heat pump will deliver its best performance. The bypass has to be built as shown below: Setting the valves of the by-pass: ○ Install the bypass with all 3 valves entirely open ○...

Guidelines Water chemistry Special care should be taken to keep the chemical balance of your swimming pool within limits: 7,0 – 7,8 Free chlorine 0,5 – 1,2 mg/l 80 – 150 mg/l (10°F – 30°F) Salt max 8 g/l Attention! ○...
Spring start-up If your heat pump has been winterized, perform the following steps when starting the system in the spring: Inspect the system for any debris or structural problems. Connect the water inlet and outlet unions firmly. Turn on the filter pump to supply water to the heat pump. Adjust the by-pass to allow water flow through the heat pump.
Maintenance and inspection Maintenance o Check the water supply to the unit often. Low water flow and air entering into the system should be avoided, as this will diminish the units’ performance and reliability. You should clean the pool/spa filter regularly to avoid damage to the unit as a result of the dirty or clogged filter.
