UNI 4 Installation Instructions
1 Planning and preparation work
1.1 Joiner / fitter
Door gaps
Check that the air moves from rooms with supply air valves
to rooms with extract air valves.
Kitchen
If the kitchen ventilator is designed with a motor, suitabl sup-
ply air must be ensured. See chapters 9 and 10 for details.
Fireplace
When using the fireplace suitable supply air must be ensured.
Installation in the building
The unit should not be placed near rooms that are sensitive
to noise. When placing by an inner wall, an isolated wall with
cut off studs and cut off boards, as well as double plaster
board, is recommended. Cabinet units in wet rooms should
be placed outside zone 2.
Suspension of cabinet unit
Suitable transoms between studs minimum (48 x 98 mm) are
required for the screws.
Access
The unit must have good access for service/maintenance.
See chapters 2 and 3 for details.
Fire requirements
Any fire safety requirements must be clarified.
Duct cover
Plan and calculate the placement of the unit and duct cover
carefully before you start. See chapters 7 for details.
Placement of heat sources
must be coordinated with
extraction valves, so that heat is not sucked straight out
through the valves or door gaps.
1.2 Plumber (if the unit has a water battery)
Water pipe layout and placement of the water battery
(channel battery)
must be planned. These must be kept
warm to avoid frost damage. See separate instructions that
accompany the water battery.
1.3 Electrician
Power supply
The units have an approx. 2.5 m cable with plug and require a
single-phase earthed socket nearby. Plug requirements: 10 A.
It is important for the plug to be accessible for servicing
when the unit is fully installed.
If a separate kitchen hood is used, it must have its own
socket (10A) in the area above the cabinet. If the kitchen
hood is going to be connected to the ventilation unit, a
minimum Ø16 conduit must be installed for the two-core
signal cable. NB!
The
power cable grommet
must be fastened with a torque
of 2.0Nm.
Wiring for control switches
Pipe Ø 20 for pulling of ISDN cable for control of the unit,
laid between the unit and an easily accessible place in the
property (e.g. outside the bathroom) and ending with a
simple flush-mounted double wall box. The control switches
are placed here. The control wire must be placed min. 30 cm
away from cables carrying mains voltage or higher.
Control panel
The control panel is adapted for concealed installation over
a
single
connection box, or surface installation on the wall.
Positioning must accord with individual
countries' electrical safety legislation. Check
which rules apply in your country.
CAUTION! Each product’s installation
instructions must be followed.

The water battery must be located in a room
with a drain.
