In contrast to heat pump operation only, a smaller amount of
water is heated up in order to minimise heating element operat-
ing periods.
It is only possible to switch the heating element manually. In this
operating state, the hot water is heated to the maximum temper-
ature of the heating element controller.
Heat pump temperature controller
Temperature control in the water cylinder and the regulation for
compressor operation is carried out by the temperature control-
ler. This controller measures the hot-water temperature via a
sensor and controls it in relation to the set value. The desired
temperature level (set value) is set via the rotary knob on the
control panel.
Air temperature thermostat
This thermostat sensor measures the hot-water heat pump tem-
perature directly upstream of the evaporator (air inlet tempera-
ture). When the temperature sinks below the set value (12 ±1.5
C, switch-back value 3 K) hot water preparation is interrupted by
the heat pump (and the ventilation operation) i.e. the heat pump
is switched off.

Storage and Transport

3.1 General Information

The hot-water heat pump should generally be stored and trans-
ported wrapped up, upright and containing no water. If handled
carefully, the unit can be transported over short distances with a
max. tilt angle of 45°. Ambient temperatures between -20 and
+60 °C are permissible during transport and storage.
3.2 Fork-Lift Truck (or Lift Truck)
Transport
The hot-water heat pump must remain installed on the pallet dur-
ing fork-lift transport. The pump should be lifted slowly. Because
of its high centre of mass, the hot-water heat pump must be se-
cured against canting. To prevent damage, the hot-water heat
pump must be lowered onto a level surface.

3.3 Manual Transport

Use the wooden pallet for manual transport. A second or third
carrying position can be determined with the help of ropes or car-
rying slings (these may be positioned around the ventilator case
and fixed to the water pipe nipples). If the pump is transported in
this manner (or with a sack barrow), the max. tilt angle of 45°
must not be exceeded (see illustration). If the pump can only be
transported in a tilted position, the hot-water heat pump ("heat
pump" switch) should not be operated until at least one hour after
installation in its final location.

ATTENTION!
The device cover cannot be used for carrying (the cover cannot withstand
larger forces!)

Set-Up

4.1 Installation Location

Installation location criteria:
 The hot-water heat pump must be installed in a frost-free
and dry room. The room temperature / air sucked in by the
hot-water heat pump should be within a temperature range
of 15 °C to 35 °C (required for heat pump operation).
 Furthermore, installation and air intake is not permitted in
rooms with air which is potentially explosive because of
gases, vapours or dust.
 In order to prevent damage to interior walls caused by damp,
it is recommended to provide good thermal insulation be-
tween the room into which the exhaust air is released and
the neighbouring rooms.
 Condensate drainage (with a siphon) must be provided.
 The air sucked in must not be excessively contaminated or
contain large amounts of dust.
 The load-bearing capacity of the foundation must be suffi-
cient (weight of the filled hot-water heat pump approx.
300 kg).
We recommend a minimum clearance of 0.5°m to allow for main-
tenance and repair work on all sides of the device. Hot-water
heat pump connection is (optionally) performed with insulated
ductwork of the NW 125, which must not exceed a total length of
10 m.
To ensure effective operation, an air circuit bend (90° NW 125)
must be installed on the blow-out side in rooms with lower ceil-
ings and without ductwork. If the air circuit bend is used, place it
onto the spigot (and for the installation of the required bush of
nominal width DN 125) of the outlet side so that the exhaust air
outlet of the air circuit bend is as far away from the unit's intake
opening as possible. The air connection stubs of the hot water
heat pump "intake stub" and "outlet stub" are labelled.
