3.5 Opening the device

The device cover is divided in two. To access the inside of the
device or to make transport easier (prevent damage), both
cover parts can be removed. To do this, the four locks must be
opened with quarter-turns in anti-clockwise direction (the lock
symbol pointing towards the front shows the status of the lock).
The cover can then be removed to the front.
To remove the air circuit cover, the two locking screws must be
removed. The cover can then be removed to the rear.

4.1 Installation location

Installation location criteria:
The domestic hot water heat pump must be installed in a

dry and frost-free room.
 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 hu-

midity, good thermal insulation between the room into
which the exhaust air is released and the neighbouring
rooms is recommended.
Condensate drainage (with a siphon) must be provided.

 The air taken in may not be excessively contaminated or
Lock
contain large amounts of dust.
open
The load-bearing capacity of the foundation must be suffi-

cient (the weight of the filled domestic hot water heat
pump is approx. 420 kg).
For fault-free operation and for any maintenance and repair
work, minimum clearances of 0.6 m are required on the left and
right of the device (see illustration). The domestic hot water
heat pump can be connected (optionally) using EPP air ducts
NW 160 mm internal, 190 mm external, which must not exceed
a total length of 10 m.
If air ducts are not used, a 90° EPP pipe bend pointing down-
wards on the outlet side can be used for sound optimised oper-
ation (see illustration)

4.2 Installation
Remove the three transport restraint screws (M12 - fixing

the device to the pallet) from the bottom of the pallet.
 Remove the pallet and mount the three M12 supporting
feet (in the plastic bag attached to the nipple of the cylin-
der pipe).
 Position the domestic hot water heat pump and align it ver-
tically by adjusting the device feet. Then tighten the coun-
ter nuts on the device feet.
