DURATECH 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
DURATECH 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
DURATECH 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) - Page 9 DURATECH 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 DURATECH 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.
