WARNING.

All window fan models are to be installed using a flexible supply cord and are supplied with
a supply cord with an internal cord anchorage.
All wall fan models are for fixed wiring only, a flexible cord must not be used.

the glass, replace the external grille.

2. Remove external grille by gently levering the top out with
a small screwdriver and remove the four pozidrive screws
and separate the two halves.

Hold the fan in position over the hole on the inside of the
window and then refit the four pozidrive screws from the
Outside.

3. Electrical: All wiring must comply with current IEE Regulations. If in
any doubt call a qualified electrician.
NOTE: All flaps should open and close together. If they do not, remove the second
flap and remove and replace until it locates properly.
Connect the cable from the fan to a double pole fused spur having a contact
separation of at least 3mm in all poles, must be used and fitted with a 3 amp fuse,
and should be sited outside any room containing a shower or fixed bath. The fan
should not be accessible to a person using either the shower or the bath.

THROUGH WALL FIXING (ALL MODELS) (DIAGRAM 1)

4. Cut a hole through the wall to suit fan and duct then fit the aluminium flexible duct
through the wall (wall fixing kit supplied separately 1300/150mm - 1299/230mm ­1301/300mm) making sure that there is a slight tilt to the outside in case any water
gets in through the external grille so it will not run into the room. Make good around
the duct. If rigid duct is used to install the fan it must be a minimum of 290mm long,
if flexible duct is used to install the fan it must be a minimum of 500mm (19 1/2 “)
from the fan to the outlet grille

5. Remove the rear grille, unscrew the four screws to remove the casing. Hold against
the outside wall directly over the duct and drill and plug the fixing holes. Screw the
grille chassis to the wall and refit the grille. It is important to make sure that the two
fixing holes are one above the other to allow the lugs on the grille to fit properly into
their slots the right way up.

assembly to the main chassis. Remove these screws then carefully separate the
two halves.
Hold the body over the hole, first ensuring that the fan is level then mark four of the
six fixing holes available (one in each corner). Drill and plug these holes. Screw the
fan to the wall and refit the front grille and replace screw caps.

7. Make the electrical connection as described in Paragraph 3.
If in any doubt call a qualified electrician.

8. Electrical Connections: Humidity Model (DIAGRAM 5)
For this fan unit to operate as a humidity fan with mechanical switch, a
permanent live and neutral supply needs to be connected via a remote
switch/fused spur unit. However, should the humidity rise above the
pre-set level the Fan will switch on and continue to run until the
humidity falls 5% below the pre-set level. In some cases, in a new
house for example, the Fan will continue to run for extended periods,
as the humidity will be high. It is, therefore, advisable that in normal
situations the Fan is pre-set at between 70% and 80% RH. In
exceptional circumstances e.g., very humid days in the Summer, the
Fan may well switch on at 80%. This is not unusual and a higher
setting may be preferable This can be adjusted by turning the adjuster
knob as indicated. (see diagram 3)

9. Electrical Connections: PIR Model with Timer (DIAGRAM 4)
The fan is sensitive to movement and will switch on when someone enters a
room (according to timer run on) and switch off when room is vacated.
Diagram 4 indicates the range of the PIR sensor.

Timer adjustment (DIAGRAM 4)

The fan is fitted with an electronic time delay switch which will run
approximately one minute after it has been switched off. The time delay can
be increased by firstly switching off the power to the fan, remove the front
cover and the inner timer cover. Insert a small screwdriver into the slot, as
shown in Diagram 4a. Turning clockwise increases the time and turning anti­clockwise reduces the time. Only adjust with the power switched off.

10. Ratings as marked on fan label. T. Max 40

NOTE:
Do not install within a shower cubicle (Use our range of shower fans) or anywhere else
where there is a high risk of the fan being sprayed with water.
Fan to be fitted a minimum 2.3 metres from the floor.

Timer Adjustment

The Timer fan will run approximately one minute after it has been switched off.
This time delay can be increased by firstly switching off the power to the fan.
Remove the cover and the timer cover as detailed in diagram 3. Insert a
small screwdriver into the slot, marked and turn clockwise to reduce the
time and anti-clockwise to increase the time. Only adjust with power switched

off. The timer will run for is 20 seconds and the maximum is about 20 minutes.
NB Timer delay is adjustable as indicated on the timer strip cover.
