5.2 Connecting the Condensed
Water Pipe
The condensed water hose is fed through the foil cladding at the
rear of the device. It should be routed so that the condensate
produced (during heat pump operation) can flow away freely.
There is a pressureless seal valve which must also be relocated
when shortening the condensed water hose (valve can be easily
removed and replaced into the hose). This valve is of special im-
portance if longer air hoses are fitted to the device or if a filter is
installed on the exhaust air side. The condensate should be
drained into a siphon (see maintenance information 7.1).

5.3 Electrical Connection

The hot-water heat pump is wired ready for use; power is sup-
plied via connection cables plugged into an earthed wall socket
(~230 V, 50 Hz). This socket has to remain accessible after in-
stallation.
To control external devices for the second heat generator (hot-
water heat pumps with internal heat exchanger only), a separate
cable has to be connected to the device via an available cable
union and be strain relieved. (For this electrical connection, the
hot-water heat pump plastic cover has to be removed.) The cable
must then be led through the available cable feedthrough pro-
vided, and guided through the partition. The electrical connection
terminal (X5 – 4/5/PE) with a floating contact to control (ON/OFF)
the external ancillary devices (pump, solenoid valve etc.) is lo-
cated on the rear of the partition in the device.
External heating element control
It is possible to optionally control the heating element via an ex-
ternal switch (e.g. timer), in parallel to the "Heating Element"
switch on the hot-water heat pump operator panel. For this con-
nection, a floating contact on the external switchgear is required.
Furthermore, an additional cable (min. 2 x 1.0 mm
outside diameter 10 mm) must be inserted into the device and at-
tached to connection 6 and 7 of terminal strip X5.

Heat pump operation is blocked if the factory-mounted copper
bridge between pole terminals 8 and 9 is removed (see Section

Start-Up

6.1 Hot-Water System

ATTENTION!
Only operate hot-water heat pump when filled with water!
Hot-water system requirements
The following materials may be found in the consumer's hot-
water system:
 Copper
Stainless steel

 Brass
 Plastic
Depending on the materials used in the hot-water system (cus-
tomer installation), material incompatibility may lead to corrosion
damage. This especially applies to zinc-plated and aluminous
materials. If there is a risk of water contamination during opera-
tion, the installation of a filter may be required.
Hot-water system start-up
 All installations at the water circuit, air circuit, as well as all
electrical installations must have been performed correctly

Filling hot-water system via external connection.

 De-aerate hot water system (open hot-water taps at the
highest extraction points until there are no more traces of
air).
 Check entire hot-water system for leaks.
 Supply voltage.
 Switch on "Heat Pump" switch (see illustration).
 The desired hot-water temperature is infinitely adjustable
(up to 60 °C) via the temperature control button (see illustra-
tion). A certain heat-up time should always be allowed for,
until the desired temperature level has been reached.
