Water side connections
4.3.1
Condensate discharge
The drainage outlet for the condensate is approximately in the middle of the base pan of the
heat pump. For the defined draining of the condensate, the enclosed condensate hose is
pushed into the rubber seal in the base pan.
4.3.2
Pool water connection
The connection should be made in accordance with the enclosed pipe system diagram
(Appendix). If necessary, additional air vents should be provided. In any case, as shown in
the pipe system diagram, provision should be made for drainage so that, after the end of the
bathing season, the system can be drained on the water side to prevent frost damage.
Directly in front of and behind the heat pump, shut-off devices must be provided. It is
important to ensure that the cross-section of the pipes is also matched to the length of the
pipe. The required minimum amount of water (see table), the pressure drop in the device, as
well as in the pipe system, must be taken into account. We recommend plastic pipes from
NW 50 to NW 80, depending on the amount of water, length of the pipe and device type.
SET heat pumps should be connected with at least NW 50 (d63).
The following table shows a recommendation and does not replace any necessary
calculation of the nominal pipe sizes.
