5.0 Wall / Ceiling Installation
a) Placing the Fan Unit.
Having established the mounting position for your fan, you need to
cut a suitable size hole through the Wall or Ceiling to accommodate
the 100mm dia. Spigot on the fan unit. Place the fan unit into the
hole and mark up 4 fixing points (4 corners of fan unit rear section,
shown in fig 2a).
Drill marked up holes and add suitable fixing plugs (Supplied by
others).
b) Prepare wiring for the fan.
Wiring can be fed through either the back or the right hand side of
the fan unit rear section.
c) Fitting the Fan Unit.
Insert 100mm dia. ducting (Pre-cut the duct length to suit the
wall/ceiling that duct is going through) through the hole previously
cut, then insert the fan unit into the duct and secure using suitable
fixings (Supplied by others). Ensure that the wiring is fed through the
fan unit rear section at the chosen exit point.
d) Wiring the Fan Unit.
Please revert to section 8.0 for full wiring diagram.
Ensure supply cable is clamped inside the unit (Clamp and Screws
supplied).
e) Setting the Humidity Trigger set point.
Please revert to section 10.0 for Set point options.
f) Finishing the Install.
Once the unit has been wired and humidity trigger set point has
been selected the front facia of the fan unit can be fitted.
Once cover and rear section are slotted together, fit the 2 fixing
screws (supplied) to the bottom face, fig. 2b.
