GX6T
●The fan is operated by a remote switch.
The fan indicator light shows when it is switched on.
●An integral timer provides an adjustable overrun period after the fan is switched off.
GX6HT
Condensation operation
●The fan operates automatically if the relative humidity is above the set level.
●The integral timer provides an adjustable overrun period after the relative humidity level has fallen.
Switched operation
●A manual operation remote switch starts the fan. The fan indicator light shows when it is switched on.
●The integral timer provides an adjustable overrun period after the fan has been switched off.
GX6HT2
Condensation operation
●The fan operates automatically at low speed if the relative humidity rises above the set level.
●The integral timer provides an adjustable overrun period after the fan has been switched off.
Boost operation
●The integral pull cord switches the fan on to run at high speed. The fan indicator light shows when high speed has been selected.
●A remote switch may be used as an alternative to the pull cord. If this is used, cut off the pull cord, after ensuring that the pull cord switch is in the “off” position.
GXS6
●This fan is operated by a remote switch.
GX6 (IP25)
●This fan is operated by a remote switch.
GX6T / GXC6T / GX6HT and GX6HT2 only
Before making any adjustments, isolate the fan completely from the mains electricity supply.
Adjusting the timer overrun
The overrun timer is factory preset at approximately 20 minutes. The time is 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).
Replace the back draught shutter/grille assembly (see “Mounting the fan in the hole” section).
Trickle ventilation
Trickle ventilation is equivalent to that provided by an airbrick or similar device.
1.Remove the back draught shutter/ grille assembly (see “Mounting the fan in the hole” section).
To allow trickle ventilation
2.HOLD THE SHUTTER VANES FULLY OPEN.
3.Push down firmly on the trickle vent catch until it clicks into position then release the shutter vanes. (See Fig.F item 6).
To fully close the shutters and stop any back draught
4.Pull the trickle vent catch towards you until it clicks into position.
5.Refit the back draught shutter/grille assembly, see “Mounting the fan in the hole” section, ensuring that the actuator lever is in the “fully down” position.
Maintenance
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 maintenance is required.
