Black Cover
The Genie/TOPS 'M' In-Line is a concealed unit
suitble for location inside or outside the bathroom
in an adjacent cupboard or roof space etc. 100mm
inlet and outlet spigots are fitted for connection to
suitable ductwork.
Air entering the unit passes through an inlet grille
and filter (optional extra). Air is discharged through
an outlet grille (optional extra) at a rate of 21 l/s.
Anti-backdraught shutters, retained in the closed
position when fan is not running, are fitted to the
white half of unit (except MX version; continuous
running - no backdraught shutter required).
Motor has sealed, self lubricating bearings and
'Heatseeker' thermal overload protection. The fan /
motor assembly is retained by spring clips to simplify
maintenance.
Interchangeable electronic control modules can
incorporate the following:
Run on Timer
Continuous low duty with boost.
As a safety feature the fan/motor assembly is
automatically disconnected when the electronic
control module is removed.
Introduction
The Genie/TOPS range of toilet & bathroom units
has been specifically designed to ventilate small
rooms such as toilets, bathrooms, cloakrooms etc.
M in-line
The EMC directive: 89/336/EEC
with modification 92/31/EEC
The low voltage directive 73/23/EEC

Note:
A gravity anti-backdraught shutter is used in this unit (except MX
unit). Therefore if the unit is installed in a vertical duct, the shutter
must be on top, the airflow upwards. See diagram C below.
e) Feed the supply cable through the cable entry. Connect the wiring
to the internal terminal block/socket. (NB. For ease of wiring, the
internal terminal block/socket should be temporarily removed from
its position). Following connection of the supply cable, refit the terminal
block/socket. (2 screws).
f) Fit the fan assembly to the case, mating its plug fully with the
internal socket. Lock with the spring clips.
g) Fit the control module into the slider. NB. Ensure that the control
Module is fully engaged with socket. See Fig. 3.
h) Fit the other section of the flexible ducting to the inlet spigot on
the remaining (cover) half of the case. 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 secure
with screws.
i) Test/run the unit.
Installation details for unit supplied with
pre-wired mains cable:
For Genie/TOPS 'M' units supplied pre-wired with nominal length
(1.5m) of cable install as follows:
a) It is assumed that a solid non reverberant mounting position has
been prepared inside the duct passage area and the necessary ductwork
already installed with adequate clearance on the inlet side to allow
fitting of the flexible ducting supplied with the unit. It is also assumed
that the electrical connections are in position. (Typically a switched
fusible spur or equivalent to comply with the 16th Edition of the
I.E.E. wiring regulations and local Electricity Board or Bye-Law
requirements).
b) Fit the mounting bracket (supplied separate in the box) to the white
half of the case, using three self tapping screws supplied.
c) Assemble the outlet spigot to the ducting and fix the unit to a solid
non-reverberant surface using two No. 8 woodscrews through the
mounting bracket, drilling and plugging the fixing area if necessary.
d) Fit the other end of the flexible ducting to the spigot on the black
half of the case.
e) Test/run the unit.
Installation
(To be carried out by qualified personnel only)
NuAire’s Genie/TOPS 'M' range of duct mounted domestic
extract fans are designed to extract small volumes of air through
100mm dia. ducting. Extract rate 21 l/s. Inlet is through a 100mm
spigot located on the front of the unit.
Units can be fitted with a selection of controls which enable them
to be linked to light switches, either directly or through run-on
circuits.
a) It is assumed that a solid non reverberant mounting position has
been prepared inside the duct passage area and the necessary
ductwork already installed. It is also assumed that the electrical
connections are in position. (Typically a switched fusible spur or
equivalent to comply with the 16th Edition of the I.E.E. wiring
regulations and local Electricity Board or Bye-Law requirements).
b) Separate the two halves of the unit by removing the screws (2
off) on the black half of the unit. Detach control module from
slider and release the two internal clips. Then remove the fan
unit. See Fig. 3.
c) Fit the mounting bracket (supplied with unit) to the half of the
case containing the wiring socket, using three self tapping screws
supplied.
d) Assemble the outlet spigot to the ducting and fix the casing to
a solid non-reverberant surface using two No.8 woodscrews
through the mounting bracket, drilling and plugging the fixing
area if necessary.

Maintenance
(General notes for the 'House Holder' and/or
Maintenance Engineer).
General
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
contamination of motor/fan assembly. The unit should also be
inspected and cleaned at least once every six months.
Isolation
WHEN CARRYING OUT ANY WORK ON THE UNIT
IT IS ESSENTIAL TO ISOLATE IT FROM THE MAINS
SUPPLY.
Procedure
At all times take care not to damage, distort or disturb 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 module. 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 socket. 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.
Run - on timer.
Run - on timer adjustment
Once unit has been installed and connected to mains supply,
switch supply 'on' making sure that the timer trigger switch is in
'off' position. Timer will now run on for half an hour. Once it
has timed out adjust timer as shown on diagram to required run
on time from 5 minutes to 30 minutes.
