General Notes
If the system is serving a room
containing 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 40oC.
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 is 250mm.
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.
Installation
IMPORTANT
The installation must be carried
out by qualified personnel in
accordance with the appropriate
authority and conforming to all
statutory and governing regula-
tions eg. IEE, COHSE etc.

and attach with the tie provided.
Push the complete assembly up through
the hole. Make sure the lamp wiring is not
impeded. Unclip internal intake finisher.
Mark and plug three holes using the three
fixing holes on the light unit. Secure by
using three No. 6 countersunk screws.
Alternatively, attach the fixing fingers to
the light unit using long screws provided.
Push the light unit through the ceiling and
twist the fingers outwards.
Then tighten the fixing fingers against the
ceiling (do not overtighten).To fit the lamp
see overleaf. Refit the internal finisher
.
Fit the reducer to the end of the ducting
using ties provided.
Install the 230V fan (instructions included
with fan) and connect to 100mm ducting.
Prepare hole through wall or soffit. Push
through unattached end of the flexduct
attach it to the grille spigot using the tie.

MAINTENANCE
CLEANING
LIGHT UNIT
Electrically isolate the unit before com-
mencing any work. Remove the internal finisher
by pulling down. Wash in warm water. The lamp
body may be cleaned using a brush or damp cloth
prior to replacing the finisher.
FAN UNIT
Electrically isolate the unit before com-
mencing any work.
Dust, fluff etc. if allowed, will build up on the motor
and / or impellers, shortening the life of the unit
and, in severe cases, lead to overheating of the
motors. It is therefore strongly recommended that
all units are fitted with inlet filters to prevent con-
tamination of motor/fan assembly.The unit should
also be inspected and cleaned at least once every
six months.
Procedure
At all times take care not to damage, distort or dis-
turb the balance of the impellers.
Separate the two halves of the unit by undoing the
screws on the black half of the unit and disengage
the two off location tags.
Remove the electronic module.
Spring aside the two clips and remove the fan mod-
ule.Visually inspect all parts, replace any damaged
items.
Using a soft brush or dry cloth remove any dust
and dirt from the fan mobile. Stubborn dirt may be
removed by careful use of a soft scraper.
Re-fit fan and electronic control module. Ensure
that the control module is fully engaged with sock-
et. Before refitting cover switch on the unit
momentarily at the isolator and check that the
green running light is illuminated before replacing
black cover and securing with the screws.
Note:
For maintenance purposes, only the black cover must
be removed.
3 Year Warranty
The three year warranty starts from the date of
delivery and includes parts and labour for the first
year.The labour element is subject to full, free and
safe access to the equipment as recommended by
the CDM regulations. The remaining two years
covers replacement parts only.
NOTE:
Installation & Maintenance of the equipment must
be as directed in the instructions provided with the
unit.
