2 Planning and preparation work
2.1 Joiner / fitter
Airflow
Check that the air moves from rooms with supply air
valves to rooms with extract air valves.
Kitchen
If a kitchen fan with a motor is included, sufficient
supply air must be ensured. See Chap. 9.1 Installation
of external cooker hood and Chap. 9.2 Adjusting
the cooker hood for more information.
Fireplace
When using a fireplace, sufficient air supply from
a separate supply air point must be ensured.
Location in the building
Location of the unit on an internal wall requires
insulation of the wall, interrupted studs and boards,
and double plasterboard or a wall structure of similar
quality (see Chap. 3.4.1 Positioning requirements).
Suspension of unit
See kap. 3 Installation på side 6.
Access
The unit must have good access for service/
maintenance. See kap. 3 Installation på side 6
for details.
Fire requirements
Any fire safety requirements must be clarified.
Location of heat sources must be coordinated with
extraction valves, so that heat is not sucked straight
out through the valves or door gaps.
2.2 Plumber (if the unit has a water battery)
Water pipe layout and location of the water battery
(duct battery) must be planned. These must be kept
warm to avoid frost damage. A closing damper with
spring must be used. See separate instructions that
accompany the water battery.
2.3 Electrician
Power supply
The units have an approx. 2 m cable with plug and
require a single-phase earthed socket nearby. Plug
requirements: 10 A. We recommend a separate circuit
for the unit. It is important that the plug is accessible
for servicing when the unit is fully installed.
If a cooker hood is to be connected to the ventilation
unit, a minimum Ø16 conduit must be installed for the
two-core signal cable.
NB!
The PG nipple for the power cable must be tightened
with a torque of 2.0 Nm if the cable is replaced.
For exact positioning of the electrical bushings,
see 11.1 Dimensioned drawing.
The assembly instructions for the
product must be followed.
Wiring for control switches.
Ø20 conduit for running the trailing cable for
controlling the unit should be laid between the
unit and an easily accessible place in the home
(e.g. outside the bathroom) and terminated with
a flush-mounted single wall box. The control switch
is located here. The control cable must be located
min. 30 cm away from any power cables. The control
cable must be max. 24 m to ensure a signal.
Control panel
The control panel is designed for flush mounting over
a single wall box or surface mounting on the wall.

Positioning of bushings for
electrical conductors.
The water battery must be
located in a room with a drain.
Positioning must accord with
individual countries' electrical
safety legislation. Check which
rules apply in your country.

3 Installation
The unit can be installed in the following ways:
• On the ceiling.
• Horizontally on a wall.
Mounting devices for this can be purchased as
an accessory.
• On the floor (lying on its back).
In this case absorption feet are recommended
(available as an accessory).
The unit comes in both a left-hand and a right-hand
version, depending on what is best with regard to duct
positioning.

3.1 Mounting the safety strap
Mount the safety strap as shown on figure 3.

Fixed safety strap
When the unit is located on the
floor, this strap must always be
mounted.
We also recommend its use for
ceiling mounting.

3.3 Ceiling mounting
3.3.1
Positioning requirements
The unit is designed to be installed in boiler rooms,
laundry rooms, stores, lofts or other suitable areas.
The unit should be positioned in such a way that there
is no danger of noise nuisance in nearby rooms.
If the unit is located in a warm room where a lot of
moisture is generated, condensation may form on the
outside of the unit during periods when the outside
temperature is low.
The base should be stable and level.
3.3.2
Space requirements
The unit must be installed with suitable space for
servicing and maintenance such as filter replacement
and cleaning of fans and recovery system.
See figure 5. The control cable with plug for
automatic control must be easily accessible when the
unit is fully installed.
These are minimum requirements and only take
service needs into account.

*
In the case of mounting in an
enclosure or a suspended ceiling,
remember that the door must be
able to open by 120°.
Ensure there is servicing access
to electrical bushings. See the
dimensioned drawing for exact
location.
Positioning must accord with
individual countries' electrical
safety legislation. Check which
rules apply in your country.

To facilitate access to the fixing bracket,
the polystyrene rings round the bosses
may be removed.

The unit must always
be mounted at
min. 3mm distance
from the mounting
substrate, as shown in
figure 12. This is to
prevent structural
sound.

Alternative 1 - Top mounting
If it is necessary to pre-drill your mounting substrate,
the drilling pattern is given here:
Select a suitable fixing device which matches your mounting
substrate.
Remember that the unit weighs 46 kg and the fixing device
must be able to support this.
