Supply / Extract Units – Installaon and Maintenance
1.0 Safety Informaon
IMPORTANT: Installaon 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 naonal wiring
regulaons.
2.0 Introducon
The Domus DX Wall 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
automac venlaon system.
Ensure adequate air replacement for the fan and any fuel burning
appliance in the room.

Inside grille
Fan assembly
2.1 Switching
Operated via a separately wired 3 amp fused spur (by others) or
operated via the optional DX-CON 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 mulple fans, depending on sensor and fan types.
Integral sensors are quick and easy to install and are aesthecally
pleasing, whilst remote sensors give the benefit of locaon close to
the pollutant source. Remote sensors can be fied with an oponal
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
and downward sloping external vanes throw off rain. The fan is IP24
splash proof approved with the motor rated at IP44.
All external components are made in so grey colours from ultra violet
stable ABS material so they will blend with most decors and will not
fade in sunlight.

Note: If 2 x 12 inch fans or 3 x 6 or 9 inch fans are used in the same
operang 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 venlaon in
accordance with building regulaons is required in all rooms. This
should be checked during commissioning with all fans in the same room
running together in all possible configuraons.
The automac shuers, motor bearings should be frequently inspected
and maintained to ensure they open fully/operate sasfactorily. Use
of an RCD and fused spur with 1A, BussmannTDC180, BS1362, fuse
(Farnell order no: 1123029) for 1 fan or 2A, Bussmann TDC180, BS1362
