Genie Fans
The Genie range of fans has been specifically designed to
ventilate small rooms such as toilets, bathrooms, cloakrooms
etc and can be surface and recessed mounting.
* An optional window mounting kit is available for this unit,
code ref WINKIT.
Air entering the unit passes through a washable filter fitted to the
front cover. Anti-backdraught shutters, retained in the closed
position when fan is not running, are fitted to the base plate.
Motor has sealed, self lubricating bearings and “heatseeker”
thermal overload protection. The fan/ motor assembly is retained
by spring clips to simplify maintenance.
Interchangeable plug in electronic control modules can incorporate:
■Run - on timer
■Humidistat
■Continuous low duty with boost.
As a safety feature the fan/motor assembly is automatically
disconnected when the electronic control module is removed.
Warning: when installing Genie units for remote switching it is
important that the pull cord (if fitted) is removed.
It is recommended that the unit is switched off (by the pullcord)
before cutting. Cut the pullcord inside the unit a little way
beyond the control module.
Fan Installation
To be carried out by qualified personnel only.
Surface Mounting
Note. It is assumed that a solid mounting position has been
selected and passages for ductwork from the outlet spigot,
as well as electrical connection prepared. In addition that
compatible ductwork has been installed.
1. Remove cover/grille assembly by removing cover screws.
Depress the top/bottom retaining tabs. (Fig. 2).
2. Remove the plug-in electronic control
module. (Fig. 3).
3. Remove the fan/motor assembly by
pulling aside the two spring clips.
4. Place the unit in the mounting position,
connect the ductwork and feed the cable
through the cable entry. Connect the
wiring to the terminal block (it may be
easier to temporarily remove the block to
facilitate wiring).
5. Drill and plug the mounting surface if necessary and secure the
unit in position, using three No. 6 wood screws.
6. Fit the fan assembly to the case, securing it
with the two spring clips. Install the electronic
control module ensuring that it is fully engaged
in the internal socket. If the pull-cord option is
required it should be fed through the
aperture on the impeller housing before
sliding the control module
into place. (see fig. 6).
If the pullcord option is
not required it must be
removed.
Replace the front cover.
7. Fit the filter which is a push fit between the front cover and the
body of the unit (see fig. 2).
8. Test run the unit noting that if a timer/humidistat option is
fitted, the unit may run-on for the duration of the control sequence.

Semi-Recessed Mounting (cont).
Important note: Remove the shutters
from the spigot if you are mounting
the Genie in the ceiling.
1. Prepare an opening 184mm x 213mm.
This will allow sufficient clearance
(approx. 5 to 10mm) all around the
unit to accept the fixing bracket
(optional). Note. Do not exceed these
dimensions, as an aperture larger than
208mm x 238mm will not be covered
by the finishing plate.
It is assumed that a solid, non-reverberant mounting position has
been selected and the necessary compatible ductwork is already
installed.
2. Position the mounting bracket (Fig.7)
in the previously prepared aperture so
that the ends of the bracket are flush
with the surface of the wall. Secure the
bracket with suitable fixings (by others)
see Fig. 5. Note: Fit finishing plate to fan
before securing to bracket.

The window mounting kit is designed for mounting the unit into
windows 4mm to 32mm thick using a 125mm dia hole. (See figure 9).
1. Employ a qualified glazier to cut a hole 125mm dia in the glass or,
alternatively, replace your window with new glass incorporating a
precut hole (Fig. 8).
2. The outer assembly consists a four bladed outlet shutter
complete with clamping plate and an outer rubber gasket moulding.
The gasket incorporates a moulded spigot which is designed to
locate inside the 125mm dia hole in the glass.
Pop-out the top three plastic shutter blades from the frame and
retain for replacement later. Position the assembly on the outside
of the glass. If only one person is installing the fan it may be helpful
to tape the assembly to the outside glass at this stage during
installation as all fixings and assembly are completed from inside
3. Working from inside the room with the inner gasket and unit
casing. Run suitable cable through the inner gasket (Holes are
provided top and bottom). Feed the cable through the access hole in
the back of the case. Allow approximately 150mm of cable to
protrude into the case. (See Fig.8). Position this inner gasket and
case assembly over the hole in the glass and locate the inner
gasket moulded spigot in the aperture.
4. Select appropriate screws and spacers from the four sets of
screws and three spacers supplied for mounting into different
thicknesses of glass, see table below.
Table 1 Glass/Screw selection
Window thickness Screw size
4mm - 6mm M4 x 12
7mm - 11mm M4 x 20
12mm - 16mm M4 x 30 + spacer
17mm - 21mm M4 x 30
22mm - 26mm M4 x 40 + spacer
27mm - 32mm M4 x 40
Should the screws foul on the back of the shutters during
installation replace with the next size down.
5. Using the three screws (and spacers fitting under the screw
heads if required) locating with the threaded inserts in the outer
assembly, draw the inner and outer assemblies together. Remove
any tape supporting the outer assembly and continue to draw the
units together until the rubbe gaskets positively locate the unit on
the window.
Note: do not overtighten the fixing screws as this may distort the
assembly. Replace the shutters in the outer frame assembly.
6. Wire unit in accordance with the appropriate wiring diagram.
A cable clamp is provided inside the case.
Note: the remaining installation procedures for Window
Mounting are as Surface Mounting description.

Run-on timer and humidity set point
Run-on timer
When installing a unit with run-on
timer the adjuster should initially
be turned fully anti-clockwise.
(This equates to a run-on of
approximately 5 minutes).
Isolate unit from supply and remove
front cover. Locate the electronic
control module situated to the right
of the fan/motor assembly.
Using a small screwdriver, turn the
adjuster to the fully anti-clockwise
position. Adjustment to the timer
can subsequently be made to suit
individual preferences.
Turn timer clockwise to increase run
on time - maximum run on time is
30 mins.
Genie humidistat set up instructions
Set humidistat to mid position (3 o’clock) when viewed as figure 10
(approximately 60% RH).
Switch mains power ON (note, switched live e.g. light switch,
should be off and the pull cord should not be pulled).
Under normal conditions the fan should be OFF. If the fan is ON
and the green LED is on, turn adjustment clockwise until the light
goes out.
Note the green light is ON when humidity is being sensed or the
switched live/pullcord is activated. If the fan is running and the
green light is OFF the fan is in its run-on period.
GENIE-H run on timer is fixed to 15 mins.

Installation of Transformer
Enclosure (12 Volt units only)
The enclosure containing the transformer is
intended to be mounted out of sight (e.g. in a loft,
cupboard, under floorboards etc.). However, if this
is not possible the transformer enclosure should be
mounted as close to the ceiling, or as far from the
"splash zone" as possible (see below for definition
of the splash zone). As can be seen from the table
of wiring sizes, it is advisable to place the enclosure
as close to the fan as possible to reduce the costs
of wiring and assist in installation.
‘Splash zone’
The ‘Splash Zone’ can be considered to be an area
within a bathroom or shower room where a person
using the bath or shower can effectively reach.
An arms reach is defined as 0.6 metres from the edge
of the bath or shower up to a height of 2.25 metres.
Procedure
1. Remove two screws securing the cover and
remove the cover.
2. Position the base enclosure on mounting
surface and route cables through knockouts.
Mark the fixing points on the mounting surface
and secure using suitable fixings (by others).
3. Connect wiring as shown.
4. Replace cover.
Keep vents clear of obstruction.
Note: No earth is to be connected between
transformer and fan.
Isolation - Before commencing work make sure
that the unit is electrically isolated from the mains
and switched live supply.
Figure 11. 12V Transformer details.
Maintenance
General
A washable filter is fitted to protect the fan/motor assembly from
towel lint, talc etc. and to prolong the life of the unit.
However, some fine dust may find its way through the filter
and could build up on the motor and/or impeller. It is therefore
strongly recommended that all units are inspected and cleaned at
least every six months.
Procedure
At all times take care not to damage, distort or disturb the balance
of the impeller. Remove the filter and the electronic control module.
Spring aside the two clips and remove the fan module Inspect and
replace any damaged items.
Using a soft brush or dry cloth remove dust and dirt from the fan
module. Wash front cover in warm soapy water and dry
thoroughly. Re-fit fan and electronic control module, replace front
cover and secure with screws. Wash filter on tepid water to which
a little mild detergent has been added. Shake out excess water and
allow to dry naturally. Replace filter. Refit the retaining screws
(Fig 3). Test run the unit.
