Installing the groundwater station

f Position the installation template horizontally at the re-
f
quired installation location. The installation template is
located on one of the flaps of the packaging box.
f Mark the holes on the wall.
f
f Drill the holes.
f
f Insert suitable rawl plugs into the holes. f
f Turn the double ended screws into the rawl plugs. f
f Remove the upper shell of the insulation from the f
groundwater station.
f Place the groundwater station over the double ended
f
screws, followed by the washers provided. Secure the
groundwater station with the relevant nuts.

3.2 Installing the brine circuit

Note
Read and observe chapter "Installing the heat source
system" in the installation instructions for the brine/
water heat pump.
f Install a safety assembly in the brine circuit.
f
Note
Some brine/water heat pumps are supplied with a
safety assembly.
Note
The heat exchanger should only be operated in coun-
tercurrent (see chapter "Specification / Standard cir-
cuits").
f Fill the brine circuit with an ethylene glycol/water mix-
f
ture with at least 25 % by vol. ethylene glycol. Check for
tightness.
f After filling, vent the brine circuit.
f
3.2.1 Heat source sensor
f Check whether a heat source sensor has already been
f
installed in the brine/water heat pump. If this is not the
case, install the heat source sensor at the groundwater
station heat pump return (see chapter "Specification /
Standard circuits").
Use contact sensor AVF 6 as a heat source sensor to capture
the brine temperature.

f Clean the pipe.
f
f Apply heat conducting paste.
f
f Secure the sensor with a cable tie. f
f Connect the contact sensor on heat pump manager f
WPM II to the heat source sensor connection (WPMW II
terminal X2/6 and earth; WPMS II terminal X12/1 and 2).
