Installation
See pictures on page 2, each
instruction is relative to the alphanumeric naming system
on images
1. Preparations
The motor unit has a bayonet mount that facilitates
removal and reassembly during installation, change
of function and cleaning.
a) Lightly grasp the spokes and turn anti-clockwise.
Lift the motor unit out of the wall frame.
b) The wall frame cover is retained by 3 screws (PH1).
Untighten them and remove the cover. The screws
remain in their respective seals (do not need to be fully
unscrewed).
2. Sealing gaskets
To avoid water penetrating the fan, the wall frame has
several integrated sealing gaskets (If needed, use silicone
sealant):
a) on the rear, seal against the substrate.
b) by the cable membrane.
c) by the screw membrane, 3 in total.
Note: Seal any gaps between fan and ventilation duct.
3. Mounting the wall frame
The fan is surface mounted on exterior wall or ceiling.
Suitable for Ø 100 mm duct (min Ø80– max Ø125).
– The cable membrane is situated in the top part of the
wall frame. Electrical connection can either be
performed from the rear (concealed) or from the
top (external). Make a hole in the seal with a suitable
sharp tool, see figure 2.
– Position the wall frame so that the cable membrane
is upp/- 45°.
– Screw the wall frame to the substrate (PH2 x3).
4. Electrical connection
NOTE! May only be carried out by qualified electrician.
During any electrical work on the fan, the voltage supply
must be disconnected.
The fan is designed for permanent installation at
230V AC, 50Hz. Double-insulated, requires no earth.
a) Connect Live & Neutral into the terminal block.
If necessary, the unused Earth cable can be stored in two
places:
b) to the right of the terminal board.
c) to the right of the cable bushing.
5. Reassemble wall frame cover and motor unit
a) Reassemble the cover on the wall frame.
Be sure that the two 12V pins are in the correct position
(rating plate downwards, arrow upwards).
b) Reassemble and lock the motor unit in the wall frame by
turning it clockwise. To locate the correct position for the
bayonet mount, the ”UP” label on motor unit and wall
frame should match.
The motor unit is correctly mounted, when the two lines
by the multi-pole switch are lined up.
6. Activate the fan – Multi-pole switch
The fan comes with the multi-pole switch to position 0.
The fan is activated by setting the switch to position 1.
According to the standard for domestic products, EN 60335-
1, it must be possible to isolate such products from the
electric power supply. This requirement is met with the
built-in multi-pole switch (2-pole, 3 mm contact gap).
