Always use a qualified electrician
All electrical connections 100-240V must be perfor-
med by a qualified electrician. Any electrical work on
the product must utilise a voltage break.
Electrical connection can be made according to the
wiring diagram on page 8-9 and the fan is suitable
for connection to either 100-240VAc or 12VDC.
NOTE:
The internal cable route must be as indica-
ted as figures K/K1 (240VAC) and L (12VDC) to
prevent the cable blocking the locator’s for the motor
assembly.
• Mark the three attachment points for the appro-
priate screws to the substrate (Figure J).
Tighten the screws so that gasket seals against the
wall.
The fan’s wall seal has a short spigot which fits inside
the Ø100 mm pipe. Make sure when mounting to
adapt the length of the wall pipe so it does not push
back the wall seal so the fan impeller cannot rotate.
Always customise a wall pipe, existing or new, so
it ends about 5 mm inside the wall surface where
the fan is to be installed. The wall frame with its seal
is prepared with 5 cable entry points (Figure F) for
concealed electrical connection or surface-mounted
cable using the dimension shown in Figure G.
• Make sure that the gasket is properly installed on
the wall frame, place it in the appropriate place
and centre it in the pipe.
The wall frame can be offset horizontally by
placing a spirit level on its support points
(Figure H and I).
