Installation and Maintenance
1.0 Safety Information
IMPORTANT: Installation or replacement of units or spare parts must be carried out by a qualified
or Nuaire approved service engineer/ electrician and in accordance with IEE or local national wiring
regulations.
2.0 Introduction
The Nuaire XS Roof Fan Kit is available in 6, 9 and 12 inch impeller sizes
suitable for supply or extract and can form the heart of an automatic
ventilation system.
Ensure adequate air replacement for the fan and any fuel burning
appliance in the room.
Two types of roof fan kits are available, one for a flat roof and the other
to cover a pitched roof installation.
The applications are ideally suitable for direct ventilation of a top storey
area.
The fan is IP24 splash proof approved with the motor rated at IP44.
Roof Terminal components are made in soft grey colours from ultra
violet stable Styrosun so they will blend with most decors and will not
fade in sunlight.
2.1 Sensors
Operated via a separately wired fused spur (by others) or operated
via the optional XS-MFC remote controller allowing supply or extract,
variable speed and automatic or manual switching of several fans if
desired (see wiring details).
2.2 Switching
Sensors are available as remote units or integral ‘plug in’ units. They
are able to control multiple fans, depending on sensor and fan types.
Integral sensors are quick and easy to install and are aesthetically
pleasing, whilst remote sensors give the benefit of location close to the
pollutant source.
Remote Sensors should be positioned at least 1.5m above the floor and
away from direct sources of heat such as radiators etc.
Options include: Humidity, Air Quality, Passive Infra Red, Temperature
and Timer versions.
Further information is available in the relevant section .
Roof Installation Accessories
A range of roof installation accessories is available. Further information

6.2 Unit Consumption & Weight
6.3 Electrical Specification
230V ~ 50Hz / 220V ~ 60Hz Class I. Motor thermally protected by
overload device. Cable: 1mm max. or min. Fuse: 3 amp (if fan is supplied
from a 5A lighting circuit, no local fuse is required).
Note: If 2 x 12 inch fans or 3 x 6 or 9 inch fans are used in the same
operating mode in the same room they should all be controlled from
the same MFC speed control. This avoids the possibility of one fan (if
speed controlled at a lower flow rate) being stalled by the other fan(s).
Adequate make-up air provision sufficient to provide ventilation in
accordance with building regulations is required in all rooms. This
should be checked during commissioning with all fans in the same room
running together in all possible configurations.
The automatic shutters, motor bearings should be frequently inspected
and maintained to ensure they open fully/operate satisfactorily. Use
of an RCD and fused spur with 1A, Bussmann TDC180, BS1362, fuse
(Farnell order no: 1123029) for 1 fan or 2A, Bussmann TDC180, BS1362
fuse (Farnell order no: 1123032) for 2 or 3 fans is recommended.
Always confirm airflow direction before commissioning.
Note figures are for extract only at 50hz.
