3.0 MECHANICAL INSTALLATION
Installation must be completed by competent persons, in accordance
with good industry practice and should conform to all governing and
statutory bodies i.e. IEE, CIBSE, etc.
The unit is designed to be ceiling/wall mounted in any plane, with the
access panel for the wiring and controls on the underside. The fan must
be fitted indoors, away from any direct sources of heat, water spray or
moisture generation.
A clear working space is required around the installed unit to
allow the cover to be removed and provide sufficient access for
maintenance.
•
The integral mounting bracket supplied with the unit can be
offered up to position on the ceiling or wall (Figures 2 and 4).
•
The fixing points for the bracket should then be marked and the
bracket installed with two screws ensuring that the bracket is
secure on the ceiling or wall.
•
Offer the unit into position inside the bracket ensuring the access
cover is face down, and locate the bracket into the moulded
bracket holders on the case sides (Figure 3).
Various spigot positions can be utilised as required to suit the system
ductwork and extract grilles. The unit is supplied with one spigot open
and two ’closed’ as knockouts when delivered but they can be opened
using a hacksaw (Figure 7).
