3 Installation

3.1 Transport

To protect the equipment against damage,
it must be transported vertically inside
its dedicated packaging. Where space is
restricted, you may also move the equipment
tipped backwards at an angle.
3.2 Positioning
1. Unscrew the four screws from the non-
returnable pallet.
2. Remove the washers.
3. Before removing the equipment from
the pallet, remove the anti-vibration
mounts from the pack supplied with
the equipment, and insert fully into the
equipment.
4. Remove the equipment from its pallet
and position it where required.
5. Level the equipment by manipulating the
anti-vibration mounts.
Checking installation conditions
The room where the WWK 300 is be installed
must meet the following conditions:
 Stable floor (WWK 300 wet weight approx.
460 kg).
 Never operate the WWK 300 in rooms, at
risk from explosion due to dust, gases or
vapours.
 Include in your considerations the
utilisation of waste heat, for example

from a boiler, tumble drier or refrigerator/
freezer.
 The available floor area in the installation
room must be at least 6 m². Never install
this equipment in rooms with a volume of
less than 13 m³.
 Never restrict the ambience around the
WWK 300 through walls or ceilings closer
than shown in Fig. 4.
 The room temperature must never fall
below +6 °C, as the ambient temperature
will be reduced by approx. 1-3 °C through
the heat pump operation. The initial
temperature level will be re-established
approx. ½ hour after the heat pump has
been switched OFF.
When installing the heat pump in a boiler
room, ensure that the boiler will not be
impaired.
3.3 DHW connection
Observe the regulations imposed by your local
water board. Install the cold water supply line
in accordance with Fig. 5.
The appliance is supplied with pipe connectors
with union nut fittings and flat gaskets for
making the connections to the cold water and
DHW lines.
To protect against corrosion, make
!
the water connection with flat
gaskets.
