EU heat pumps 3. Installation and connection 3.1 Remarks The factory only provides the heat pump unit; the other parts, including a contingent by-pass, are to be provided by the user or the installer. Attention: Please take the following steps when installing the heat pump: 1. -
Page 7: Distance From The Pool
EU heat pumps 3.3 Distance from the pool Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance from the pool, the greater the heat loss from the piping. Since the piping is buried for the most part, heat loss is minimal for distances of up to 30 meters (15 meters to and from the pump = 30 meters total), unless the soil is wet or the water level is high. -
Page 8: Typical Setup
EU heat pumps 3.5 Typical setup Note – This setup is just an example 3.6 Adjusting the by-pass Adjust the by-pass as follows: open the 3 valves completely • slightly close valve 1 until • water pressure has increased with approximately 100 to 200 grams (see also 3.8) close valve 3 about halfway to •... - Page 9 EU heat pumps 3.7 Electrical hook-up Important - Although the heat pump is electrically isolated from the rest of the unit, this only prevents the passage of electricity to or from the pool water. Grounding the unit is still required to protect yourself from short circuits inside the unit.
- Page 10 EU heat pumps 3.8 First time start-up Note - In order for the unit to heat the pool (or spa), the filter pump must be running so that the water can circulate through the heat pump. Without this circulation, the heat pump will not start. When all connections have been made and checked, you should follow these steps: 1.

EU heat pumps Parameter 10 sets the desired operation mode for the fan speed. Value for parameter 10 Fan control Low fan speed High fan speed Automatic fan speed (high speed when air temperature is below 10°C, low speed when higher than 15°C) Low fan speed between 9PM and 8AM, high speed at other time Automatic running according to a combination of value 2 and 3 Parameters are modified as follows:... -

Page 15: Protection Systems
EU heat pumps 5. Protection systems EU heat pumps are equipped with the following standard protection systems: 5.1 Water pressure switch Thanks to this pressure switch, the heat pump will not work when the filter pump is not working (and the water is not circulating). -
Page 16: Anti-Frost Protection During Winter
EU heat pumps 5.7 Anti-frost protection during winter This protection can only be activated if the heat pump is in STAND-BY mode. 5.7.1 First anti-frost protection If the filter pump is controlled by the heat pump (regardless of the value for parameter 9) and when the water temperature lies between 2 and 4 °C and the air temperature is lower than 0 °C, the filter pump will be automatically turned on to prevent the water from freezing in the piping. -
Page 17: Directions
EU heat pumps 6. Directions 6.1 Swimming pool water chemistry Special attention should be paid to the chemical balance of the pool water. The pool water values should always stay within the following limits: Min. Max. Free chlorine (mg/l) TAC (mg/l) Salt (g/l) Important: failure to comply with these limits will invalidate the warranty. -
Page 18: Heat Pump Winterizing
EU heat pumps 6.3 Heat pump winterizing Important: failure to take the necessary precautions for winterizing can damage the heat pump, which will invalidate the warranty. The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop below the freezing point. -
Page 19: Maintenance And Inspection
EU heat pumps 7. Maintenance and inspection 7.1 Maintenance Check the water inlet and drainage often. The water and air inflow into the system should be sufficient so • that its performance and reliability does not get compromised. You should clean the pool filter regularly to avoid damage to the unit caused by clogging of the filter. - Page 20 EU heat pumps Problem: the heat pump doesn’t work Observation: the screen does not light up and the fan/compressor doesn’t make a sound Possible cause Solution No electrical power supply Check power supply (wiring, fuses, ...)
