Installation
5.1
Installation Site
CAUTION!
The following applies to the selection of the installation site:
¾
The HPWH must be sited in a freeze-proof room (preferably within the building thermal envelope).
The room air temperature and/or the air taken in by the HPWH should be within a temperature
range of 8 °C to 35 °C (required for heat pump operation).
¾
A field-installed condensate drain (with siphon) must be provided.
¾
The floor surface must have adequate load bearing capability (the estimated weight of the plant is
475 kg when fully charged). When installed on an upper floor, utmost attention must be paid to vi-
bration decoupling measures for acoustic attenuation.
¾
The HPWH must not be installed in areas or operated with exhaust air if there is an explosion haz-
ard due to dust, gases or vapours.
For trouble-free operation as well as the performance of maintenance and repair work, minimum clearances
of at least 0.6 m must be maintained all around the unit. A minimum ceiling height of approx. 2.50 m is re-
quired for operation of the HPWH without
airducts or airduct elbows (
installation) (see Fig. 7). The connection to the
HPWH is effected (optionally) by means of
insulated airducts (NW 160) which must not
exceed a total length of 10 m.
If the ceiling is lower and no airducts are
used, an air ducting elbow (90° NW 160)
must be used on the outlet air side (to en-
sure effective operation).
When an air ducting elbow is used, care must
be taken that it is slipped onto the flange collar
of the discharge side in such a way that the
discharge opening of the air ducting elbow is
as far away from the intake opening of the unit
as possible. Moreover, the minimum clear-
ances shown in Fig. 7 have to be complied
with. The air connection fittings of the HPWH,
i.e. "intake connector" and "discharge connec-
tor" are identified by adhesive labels.

Installation
¾ From the underside of the pallet, remove the three M12 bolts securing the pallet to the unit as a shipping
safety measure.
¾ Remove the pallet and mount the three levelling feet (M12 bolts – contained in the polybag, secured to the
storage tank pipe nipple).
¾ Move the HPCDW into final position and adjust the unit so that it is perfectly perpendicular by adjusting
the levelling feet! Subsequently, tighten the check nuts provided on the levelling feet.
"free-blowing"
* ) the minimum distance of the discharge opening of the airducting
elbow to the wall is 1.2 m
The minimum ceiling height for "free-blowing installation" is approx.
