3.0 INSTALLATION
Installation 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 spray
or steam generation. The fan can be installed at any 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 diameter discharge spigot and the
chosen 100mm, 125mm diameter and/or 110 x 54mm rectangular inlet
spigots.
The unit is not fitted with a backdraught shutter (when using the
continuous background vent facility a shutter is not needed). However
a backdraught shutter is available from Nuaire if required.
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 diameter discharge spigot for fitting during installation.
3.1 Unit Installation
The integral mounting bracket supplied can be offered up to position,
the fixing points marked through and the bracket installed with 4
screws by others (figure 2).
Offer the unit into position and locate the bracket into the slots in the
case before fixing with the single bracket fixing screw.
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 have been located in their correct position, adjust the
damper with a screwdriver (figure 4).
