The picture below illustrates the minimum required distances from each side of the heat pump.
3.2 Distance to the pool
Install the heat pump as close to the swimming pool as possible to minimize heat loss through the piping.
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. If the piping is buried, heat loss will be 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. Heat loss per 30 meters can be roughly be estimated at 0.6kw-hour (2000 BTU) for

(water pressure increased from 10 to 20 bar)
VALVE2
–
Completely open
VALVE3
–

Setting the valve of the by-pass:
1. Open all 3 valves entirely
2. Slightly close valve 1
3. Close valve 3 about half way to adjust the
