Installation Instructions for the 100mm 4''/ 120mm 5'' / 150mm 6''
Standard, Pullcord, Humidity, Humidity Pullcord
and Timer Extractor Fans
Important Notes
(i) When installing fan through an external wall, an external wall grille must be fitted at all times.
(ii) This fan must be installed by fixed wiring only. A flexible cord should not be used.
(iii) 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
must be sited outside any room containing a shower or fixed bath. The fan must not be accessible to a person using either the
shower or bath. Fan to be fitted a minimum of 1.8 metres from floor. When fitting through an external wall, an external grille
must be fitted at all times.
iv)
When the fan is mounted on the wall it MUST be installed with the PCB and connection terminals at the TOP as shown in diagrams 1, 2 & 3.
v) This product should be fitted by a competent person who is aware of Part P Building Regulations. All wiring must comply with current IEE
Regulations. Must be securely fixed and the cable must be a minimum of 1mm sq in section. If in doubt contact a qualified electrician.
vi) For best results this extractor fan should be fitted as high on the wall as possible, or if preferred, on the ceiling.
vii) Do not install the unit in a shower cubicle.
viii) Switch off mains supply before making electrical connections.
If in any doubt contact a qualified electrician.
viiii) This fan is double insulated and does not require an earth
1. Cut a hole in the wall to suit the fan and ducting (112mm/4
If the fan is to be fixed in the ceiling ensure that the hole is between the joists.
2. Fix ducting flush to the plaster of the wall or ceiling.
3. Remove the front cover. To remove the front cover, first remove the hole plug than using screw driver to remove the self taping screw, then cover can be remove unclip.
4. Hold the body of the fan against the wall or ceiling and mark the four screw holes and the cable entry.
IMPORTANT: Ensure that the fan is square on the wall or ceiling.
5. Bring the power cable into position, as marked. Allow an extra 230mm (9“)
protruding to facilitate connection.
6. Replace front cover and secure using the front cover screw and insert the hole plug in screw hole.

Wiring of Humidity Model - Diagram 1
For this fan to operate as a normal Time Delay Unit with Humidity Override, i.e. when connected to a Switched Live Supply coming from
the light switch into the Fan, the Fan will operate when the light is switched on and will switch itself off after the pre-set time. 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 be pre-set at between 0% 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.
For the fan to operate a normal time delay unit with humidity over-ride i.e. when connected with a switch live coming from the light
switch into the fan. The fan will operate when the light is switched on, and switch off after about 20 seconds to 20 minutes (timer is
pre-set for the minimum). However should the humidity in the room reach about 75%, which will happen if the shower is run or the
bath filled with hot water, the fan will switch on and keep running until the humidity has been reduced to a normal level, about 65%.
Requires neutral, switch live and perm live supply. Refer to internal wiring label and Diag 2 of this instruction for correct
connection.
NOTE: When the humidity fan is first installed they can run continuously for several hours.
Wiring of Humidity Model (Humidity Sensor with Pullcord Overide)
This fan requires a permanent live and permanent neutral supply. Refer to internal wiring label for correct connection. The fan will
operate should the humidity in the room reach to a higher level than the sensor detects and will run continuously until the humidity
llevel is reduced. The fan is fitted with a pullcord overide that will operate the fan when the humidity is not high enough to operate
the sensor.
Wiring of Humidity Model (Humidity Sensor Only)
This fan requires a permanent live and permanent neutral supply. Refer to internal wiring label for correct connection. The fan will
operate should the humidity in the room reach to a higher level than the sensor detects and will run continuously until the humidity
level is reduced.
Wiring of Standard Model - Diagram 2
This fan can be either operated from a suitable remote switch or a separate pullcord switch fitted to the ceiling of the room or can be connected to the light switch so that
the fan will start when the light is switched on. The cable from the fan must be connected to a double pole fused spur having a contact separation of at least 3mm in all
poles, it 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.
Wiring of Pullcord Model - Diagram 2 (THIS MODEL IS NOT SUITABLE FOR CEILING FIXING)
This fan has its own integral pullcord on/off switch. The cable from the fan must be connected to a double pole fused spur having a contact separation of at least 3mm in
all poles, it 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.
Wiring of Timer Model - Diagram 3
The fan can be either operated from a separate pullcord switch fitted to the ceiling of the room or can be connected to the light switch so that the fan will start when the
light is switched on. 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.

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
timer cover and bracket and carefully turn the thumb wheel 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.
