WIND W/WALLFANS
The SVC6 range are axial extractor fans suitable for use in domestic kitchens and light
commercial environments. They may be used in other applications where a high level of
ventilation is required.
The SVC6 is designed primarily as a window fan but it can also be installed on a wall or
a ceiling but should not be ducted over 2 metres. When fixing through the wall a wall
fitting kit SVC901W is required.

AGUIDET VENTILATI N
WHERET SITEY URFAN
Incorrect siting of an extractor fan can
severely impair its efficiency. It is
therefore, important that the fan is
correctly sited using the following
principles.
• To ensure maximum air flow through
the whole room, mount in the window,
wall or ceiling furthermost from the air
inlet point at high level.
• Do not position a fan where
temperatures are likely to exceed 50ºC
(for example above a cooker hob or
eye level grill).
• When installing in a room with an open
fire or stove without a balanced flue,
ensure that there is sufficient
replacement air to prevent the fan
drawing air back down the flue.
• A 230volt fan installed in a bathroom
must not be within reach of a person
using the bath or shower.
• Always use an in-duct or Low Voltage
Fan (SELV) to ventilate a shower
cubicle.
• When installed in a window, the fan
should be as high as possible and
should not be fitted in an opening
window if it can be avoided.

These models are equipped with humidity control on slow speed and pull-cord switch
over-ride to high speed. The slow speed is intended to turn on when a pre-set humidity
has been exceeded and off when that level has been reduced. The fan may be operated
via the pull-cord switch at any time. The slow speed cannot be operated independently
of the humidity control.

Isolate from power supply. Remove front cover. The timer adjuster is positioned at the
top and is turned clockwise for more over-run time and anti-clockwise for less. (Range is
30 seconds to approx 25 minutes - factory default is set at minimum).
HUMIDISTATM DELSSVC150HTB/SVC150HB/SVC150HBTW

The humidity control may be tested by breathing through the sensor grille located at the
top of the fan unit. Please note that there is a 15 second delay between the sensor
operating and the fan starting.
D N T test the sensor with steam from a kettle.
MAINTENANCE
aintenance free, but should be cleaned at least once a year.
CLEANING
Isolate from power supply. The outside of the fan may be cleaned with a damp cloth and
washing-up liquid. If the fan unit is heavily soiled it should be removed from its mounting.
The main fan chassis can be cleaned with a damp cloth. Do not immerse in water. The
remaining parts may be cleaned with water and washing-up liquid. Dry and re-install.
The discharge grille may be removed from the window by removing the top and screws.
Clean as above and replace. It is not necessary to remove the surface mounting housing
and discharge grille spigot from window/wall to clean them.

WARNING
Positioning of the fan unit must be so as to avoid back flow of gases from open flue gas
or other open fire appliances. To prevent combustion gases entering the air inlet, this air
inlet must not be positioned above or within 1.5 metres of a combustion flue vent.

It is recommended that fans be connected into the lighting circuit, with double pole
(3mm) isolation provided before the room light switch and suitably fused, in accordance
with IEE Regulations.
Window Fans should be connected to power supply using a flexible cord with conductors
of between 0.75mm2and 1.5mm2only.
Wall and ceiling mounted fans for fixed wiring should be connected to the power supply
via a cable with solid conductors of 1mm2to 1.5mm2only.

Strip the fan unit to it’s three components as described on page 4. Cut 184mm (71/4”)
hole in glass. This job is best done by a glazier.
Fig 1. Remove the 4 brass clamp nuts from the fixing kit then insert the discharge
grille spigot through the hole from the outside. Locate the surface mounting
housing over the studs. ake sure that the weather seals are not displaced.
Fit clamp nuts. Do not over-tighten.
Fig 2. Insert power supply flex through entry at the top of the surface mounting
housing and through the access hole in the main fan chassis. Fit the main fan
chassis to the surface mounting housing. Refer to Page 7 for wiring.

WALLFIXINGKITSVC901W
We recommend the use of this fixing kit as it contains all the necessary parts to surface
mount or flush fit the SVC6 fan unit.
SURFACEM UNTING
Cut a hole through wall in desired position to take the 150mm duct supplied in the fixing
kit. It is important that there is at least a 5º downward slope towards the outside to allow
for condensation drainage.
The duct should be cut so that it is flush with both sides of the wall less 60mm which is
the length of the mounting socket adaptor body.
Strip the fan to its four main components as described on page 4. The outside grille
should be fitted into the discharge duct and secured to the outside wall using the wall
plugs and screws supplied with the fixing kit. At this point check that the 6” ducting and
mounting socket adaptor are flush with the inside wall before completing installation.
Use the surface mounting housing as a template to mark the fixing screws and cable
entry positions on the inside wall. ake sure surface mounting housing is accurately
lined up with discharge duct and adaptor.
Fix the surface mounting housing to the wall using the wall plugs and screws supplied
with the fixing kit ensuring that the electrical cable is through the cable entry hole in the
surface mounting housing.
Fit the fan into the surface mounting housing and make electrical connections as described
on pages 8 and 9 and refit front cover.
FLUSHM UNTING
Cut hole through wall in desired position. On the outside allow clearance for the 150mm
duct and on the inside allow clearance for the flush mount socket, this is a little larger
than the duct. It is important that there is a downward slope towards the outside to allow
for condensation drainage.
When the hole through the wall is complete, a length of adhesive sealing strip should be
fixed around the flush mount socket spigot. Now insert the flush mount socket into one
end of the 150mm duct and fit the assembly into position temporarily and mark duct for
cutting to length. If surface mount socket requires trimming, ensure that a depth of at
least 55mm is retained. The duct assembly should be flush with both sides of the wall.
When length is correct, grout the assembly firmly into position.
Strip the fan to its four main components as described on page 4. Assemble the fan as
previously detailed for surface mounting but discard the surface mounting housing and
complete the installation as previously described.
Note: When flush mounting the fan unit the power supply cable must be chased into
the wall surface. Apply the self adhesive sealing strip around the fan chassis
spigot before fixing to socket using wall plugs and screws supplied with fixing
kit.
ake electrical connections as described on page 8. Refit front cover.
