INSTALLATION
IMPORTANT:
The fan should only be used in conjunction with fixed wiring.
Before starting any kind of electrical work, live cables must be disconnected.
CEILING MOUNTING
1
When mounting on a ceiling/wall, the fan must be installed in a duct protected by an
external air grille that must comply with the country’s standard requirements for
preventing access to the fan’s propeller.
2.
Holes are preferably made with a hole saw 108 mm in diameter for 100 mm fans.
Key dimensions, (see Figure 3). NOTE that the fan is seen from behind in this view.
To avoid condensation in draught ducts (in winter), these must be insulated if they pass
through unheated spaces, e.g. cold winds.
3.
Press the two clamps on to the base of the fan (see Figure 2) and remove the cover from
the chassis.
4.
Mark the screw holes (see figure 3) using the fan base plate as a drilling template. Drill, plug
and screw the fan in place.
5.
If the fan is connected to the draught duct in the ceiling, the back draught shutter must be
removed. NOTE: A back draught shutter is actually harmful if the fan is fitted in a ventilation
duct with a natural draught. After installation, make sure that the impeller can rotate freely.
6.
Replace the fan cover, making sure the hooks lock the cover securely.
WALL MOUNTING
1.
When mounting on a ceiling/wall, the fan must be installed in a duct protected by an
external air grille that must meet the country’s standard requirements to prevent access to
the fan’s propeller
2
Holes are preferably to be made using a 108 mm diameter hole saw for 100 mm fans.
Insert the wall tube, tilt the tube slightly downwards from the fan, cut to length and fix both
ends in place in line with the wall surfaces.
3.
Press the two clamps on the bottom of the fan (see figure 2) and remove the cover from
the chassis.
4.
Mark the screw holes (see Figure 3) using the fan’s base plate as a drilling template, adjust
the base plate until it is level using the built-in spirit level (see Figure 1)
Drill, plug and screw the fan in place. Secure the outer wall grille in place with the slats
facing downwards so that rainwater drains off.
(Note: - The wall tube used must not be shorter than 100 mm to leave enough room for the
cold race protection to operate.
5.
See points 5 and 6 above.
Open the internal
cover to access the
spirit level bubble
and
terminals.
