General Notes
If the fan is installed in a room con-
taining a fuel burning appliance of a
non-balanced flue design, it is the
responsibility of the installer to
ensure that sufficient replacement
air is provided to prevent products
of combustion from being drawn
down the flue when the fan/ light
unit is operating.
The unit should not be sited where
it would be subject to a direct
source of heat in excess of 40
o
C.
Once fitted into ceiling void or loft
space, do not cover light body, fan
or 12V power supply unit with any
insulating materials.
Minimum void height when fitting
into ceiling space and minimum
distance for light is 200mm.
ISOLATION
Note that the unit must be
provided with a means of iso-
lation (by others) for mainte-
nance purposes etc. An RCD
trip device must be included
between the power supply
unit and the mains if the unit
is fitted in zone 1 as defined
in IEE regulations.
Refer to Wiring Instructions
overleaf.
