The plate heat exchanger is to be flushed with a suitable cleaning agent
in counter-flow direction. If chemicals are used for cleaning, please en-
sure that they are compatible to stainless steel, copper or nickel. Failure
to comply can result in destruction of plate heat exchanger!
(only possible with additional electrical module)
The following components are required for heating a swimming pool:
 1x 3-way motor ball valve (Z20638).
 1x swimming pool sensor with immersion sleeve (Z14783 and Z13344).
 1x swimming pool upgrade kit (P11108, P11159 or P11225).
The following can be used as heat source:
 The ground: by connection to a horizontal geothermal absorber (e.g.
PE-pipe 20x2) or a vertical geothermal absorber (geothermal probes).
 The groundwater: by connection to a well system, using an accessories
kit available from WATERKOTTE to monitor the flow at heat source side
and separation heat exchanger (heat source side).
 The layout of the heat source system must be according to the
WATERKOTTE dimensioning information.
 Refer to the performance table to find the volume flow for the corre-
sponding heat pump.
 The heat source connections (2") feature an external pipe thread for flat-
sealing connections with union nut and insert.
 A pressure expansion tank has to be installed on site.
 A circulation pump has to be installed on site.
 One safety fitting (air diverter / filling pressure gauge / safety valve has to
be installed on site.
 In case of water glycol systems, it is not permitted to use steel pipes
and other steel components in the water circuit. Use stainless steel,
copper, brass or plastic - such as PE - for instance.
Steel pipes and other steel components should also be avoided in
groundwater systems.
To prevent frost damage, the heat source system must be filled with about
30 % WATERKOTTE ethylene glycol (freezing point at about
-15 °C). The heat source system must be properly filled with the operating
media and vented.
For groundwater heat pumps the installation of a separation heat exchang-
er is absolutely essential to avoid direct damage to the heat pump. The in-
termediate circuit must be filled with about 15 % ethylene glycol. The fol-
lowing WATERKOTTE accessories are required for groundwater applica-
tion:
 Filter
 Flow monitoring
 Separating heat exchanger
