Safety equipment:
Safety valve, start-to-leak pressure 2.5 bar
An additional expansion vessel can be connected
3.2 Switch box
ATTENTION!
Before opening the device, ensure that all circuits are powered down.
The switch box is located in the upper area of the hydro tower.
After removing the front cover, the switch box is freely accessi-
ble.
The switch box contains the supply connection terminals, heating
contactors, umbilical cable connections (connecting line to the
heat pump) and the heat pump manager (HWK 332 Econ).
3.3 Heat pump manager
The integrated heat pump manager (HWK 332 Econ) is a con-
venient electronic regulation and control device. It controls and
monitors the entire heating system based on the external tem-
perature, as well as domestic hot water preparation and safety
systems.
The external temperature sensor (to be connected on site) in-
cluding the fixing accessories, is included in the scope of supply
of the controller.
The enclosed operating instructions describe the function and
use of the heat pump manager.
4 Transport
A wooden pallet should be used to transport the heat pump to its
final installation location. The basic device can be transported
with a lift truck, a pushcart or similar.
ATTENTION!
The hydro tower is to be fixed to the transport pallet with screws.
5 Installation
5.1 General
The unit should always be installed indoors on a level, smooth
and horizontal surface. The hydro tower must be installed in such
a way that maintenance work can be carried out from the operat-
ing side without hindrance. This can be ensured by maintaining a
clearance of 1 m at the front. The space required (approx. 30
cm, see dimension drawing) for replacing the protective anode
must be taken into consideration when determining the required
height of the installation room. It must be installed in a room pro-
tected from frost and with short pipe runs.
Setup and installation must be performed by an authorised spe-
cialist company.
If the hydro tower is installed on an upper floor, the load-bearing
capacity of the ceiling should be checked. On account of the
acoustics, measures for isolating possible vibrations should also
be very carefully planned. Installation on floors above wooden
ceilings is not recommended.
5.2 Sound
To prevent solid-borne sound from being transmitted to the heat-
ing system, we recommend connecting the heat pump circuit to
the hydro tower using a flexible hose.
