INSTALLATION
• Note: Installation assumes the unit and grille
components can be installed before the
ducting. If the ducting will be inaccessible
after either of these are in place, the opening
for that component should be increased to
110mm, this will allow the ducting to pass
through the hole for attachment. The ducting
can then be installed first.
Installing the isolating switch
and cables
1. Check there are no buried pipes or cables
(e.g. electricity, gas, water) in the wall or
above the ceiling where the isolating switch
and operating switch is to be located. If in
doubt, seek professional advice.
Wet rooms: the operating switch
must be situated so that it cannot
be touched by persons making use
of the bath or shower.
2. Isolate the mains supply.
Warning: do not make any
connections to the electrical supply
at this stage.
3. Lay the cable from the isolating switch to the
transformer location via an operating switch.
4. Lay the two lengths of suitably rated 2
core cable from the transformer to the unit
location.
5. Lay the cable from the isolating switch to the
point of connection to the mains supply.
6. Install the isolating switch and operating
switch as per the manufacturer's
instructions.
7. Make all connections within the isolating
switch and the operating switch only.
Installing the Whisper Silent
Shower Light Fan
1. Remove the front cover by depressing the
latch through the slot on the side of the
cover and pulling away. Refer to Figure 3.
If working above ground floor
level, safety precautions must be
observed.
Mounting using the fixing screws and plugs:
2. Insert the back-plate into the 100mm hole in
the desired orientation. Orientate so that the
cover latch release slot is easily accessible.
3. Mark the centres of the screw holes and
cable entry. Refer to Figure 4.
4. Remove back-plate and drill holes to the
appropriate sizes.
5. Fit wall plugs (supplied), as required.
6. Reposition back-plate and secure with
screws (supplied). Take care not to
overtighten.
Mounting using the clamping brackets:
7. Insert the back-plate into the 100mm hole
in the desired orientation.
8. Tighten the two clamping brackets. Tighten
both brackets a little at a time until secured.
9.
To wire unit - Refer to Wiring the Whisper
Silent Shower Light Fan unit. To re-fit the
10.
front cover, first hook in the side opposite
to the latch and swing closed until latch
clips into place. Ensure any wiring is not
pinched when closing the unit. Do not
press on the light unit or outer fascia
cover; only apply pressure over the latch.
Installing the External Vent Grille
1. Insert the Vent Grille into the 100mm hole in
the desired orientation.
2. Mark the centres of the screw holes.
3. Remove Vent Grille and drill holes to the
appropriate sizes.
4. Fit wall plugs (supplied), as required.
5. Reposition Vent Grille and secure with
screws (supplied).
Installing the Flexible Duct
1. Lay the duct from the back of the unit to the
external vent grille. Please ensure:
- Any bends are not kinked.
- From the back of unit the duct should
protrude out straight for at least 60mm before
the first bend. This is to ensure that the
backdraft flaps are free to open and close.
- After the first bend the duct runs
downwards so that any condensation that
occurs runs out towards the external vent.
Refer to Figure 5.
- Duct is fairly taut but not overly stretched
that there is risk of pulling itself away from
either end.
2. Push ducting over the back of the unit and
secure with tie-wraps.
3. Push ducting over the back of the external
grille and secure with tie-wraps.
