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 Ceiling Fan Kit is available in 6, 9 and 12 inch impeller
sizes suitable for supply or extract and can be the heart of a room’s
automatic ventilation system.
Ensure adequate air replacement for the fan and any fuel burning
appliance in the room.
2.1 Switching
Operated via a separately wired 3 amp 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.
2.2 Sensors
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 can be fitted with an optional
security strap to prevent unwanted tampering.
2.3 General
The removable interior grille provides easy access while the external
rotor motor makes for simple removal of the push-on impeller for
cleaning. Upward angled interior grille vanes shield workings from view.
The fan is IP24 splash proof approved with the motor rated at IP44.
Fan casing, impeller and shutter shall be manufactured from UV
stabilised ABS polymer. All models shall include an economy /high
efficiency setting facility and are dove grey in colour.

5.2 Unit Consumption & Weight
5.3 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.
