nstallation must be carried out by competent personnel
in accordance with the appropriate authority and
conforming to all statutory and governing regulations.
The fan must be fitted indoors, away from sources of water

angle using the integral mounting bracket supplied (figure 2).
It is assumed that a solid non-reverberant mounting
position has been selected and the electrical mains wiring
and any optional control wires have been made ready.
It is also assumed that compatible ductwork is already
installed and ready to be connected to the 125mm dia.
discharge spigot and also the chosen 100mm dia, 125mm
dia and/or 110 x 54mm rectangular inlet spigots.
Note the unit is not fitted with a backdraught shutter.
(When using the continuous background vent facility a
backdraught shutter is not needed). However a back-

An integral fixing bracket with a single bolt fixing allows
easy mounting and removal of the unit when necessary.
The unit is supplied with the 125mm dia. discharge spigot
for fitting during installation.
2.1 Unit fixing
The integral mounting bracket supplied can be offered up to
position, the fixing points marked through and the bracket

Various damper/inlet spigot positions can be utilised as
required to suit the system ductwork and extract grilles as
all spigot positions are removable.
After the spigots has been located in their correct postion,
