adjustable between approximately
2 to 20 minutes.
1. Remove the back draught shutter/
grille assembly (see “Mounting the
fan in the hole” section).
2. Turn the adjuster marked “T” anti-
clockwise to reduce the timer overrun
(see Fig.H).
3.
Turn the adjuster clockwise to increase
the timer overrun (see Fig.H).
4. Replace the back draught shutter/
grille assembly (see “Mounting the
fan in the hole” section).
Adjusting the humidistat setting
The internal humidity sensor is factory
set at approximately 70%. The level is
adjustable between approximately
50% and 90% relative humidity.
Remove the back draught shutter/grille
assembly (see “Mounting the fan in the
hole” section).
Turn the adjuster marked “H” anti-
clockwise to decrease the relative
humidity level of the room (see Fig. 1).
Turn the adjuster clockwise to increase
the relative humidity level of the room
(see Fig.l).

A QUALIFIED ELECTRICIAN MUST
CARRY OUT ALL CLEANING.
NOTE: THE FAN WILL CONTINUE TO
OPERATE WITH THE INNER GRILLE
REMOVED HENCE IT MUST BE
ISOLATED COMPLETELY FROM THE
MAINS BEFORE ANY WORK IS
CARRIED OUT.
1. Before cleaning, isolate the fan
completely from the mains
electricity supply. Allow 3 minutes
for the impeller to stop rotating
and the powered shutter to close.
(Cleaning on the GXC6 and GXS6
can begin once the impeller has
stopped rotating).
2. Remove the back draught shutter/
grille assembly by pressing the
release catch located on the side of
the unit with a 6mm screwdriver or
coin, whilst pulling the grille forward.
To remove the back draught shutter,
lay face down and pull shutter
forwards see Fig.G1 and Fig.G2.
3. To remove the impeller. Unscrew the
central screw and remove it together
with the washer. Place screw and
washer to one side.
4. To clean the impeller, either wipe it
with a damp, lint free cloth or wash it
in warm soapy water. Thoroughly
dry the impeller and refit.
Replace the screw and washer
ensuring that they are securely fitted.
5. Clean the back draught shutter/grille
assembly and impeller in warm soapy
water.
Do not use strong detergents
or chemical cleaners.
6. Thoroughly dry the back draught
shutter/grille assembly and refit by
sliding the grille back over the realise
catches, the catches will locate in and
secure the grille (see Fig.G3 and
Fig.G4). For GXS6 MODEL: Ensure
that the actuator lever is in the “fully
down” position.
7. Do not immerse the fan in water or
other liquids to clean any other
parts of the fan.
Never use strong solvents to clean
the fan.
Apart from cleaning, no other
