3.0 Genie-DC Commissioning
a) 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 1 minute).
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 60 mins. Not e: for units fitted with
humidistat control (H variants) run-on timer is fixed at
15 minutes.
b) 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.
Not e the green light is ON when humidity is being sensed or
the switched live/pull cord is activated. If the fan is running
and the green light is OFF the fan is in its run-on period.
c) Speed control
All variants are fully speed controllable. ‘S and H’ variants are
equipped with speed control for the boost function only. ‘X and XH’
variants are equipped with control of both trickle and boost speed.
4.0 Genie-DCE Commissioning

7.0 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 dustmay 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.
8.0 Replacement of Parts
Should any component need replacing Nuaire keep extensive stocks
for quick delivery. Ensure that the unit is electrically isolated,
before carrying out any work.
When ordering spare parts, please quote the serial number of the
unit and the ARC number of the purchase if possible.
(This information will be available on the fan label).
9.0 Warranty
The 5 year warranty starts from the day of delivery and includes
parts and labour for the first year. The remaining period covers

6.0 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.
Not e: No earth is to be connected
between tr ansformer and fan.
