5. Removing the grille, Firstly remove the front cover by carefully pulling each corner of the front panel until it is
free to be removed from the inner grille (Fig 1). Unscrew the two screws at the bottom of the inner grille. The
screws will remain in the inner grille but will be loose when the grille is ready to be removed (Fig 1).
Lift the
inner grille from the bottom edge.
6. Remove the Spigot Ring from inside the carton and clip over the Spigot Adaptor making sure the lip on the
Spigot Ring locates firmly inside the groove on the Spigot Adaptor (Fig 2). Ensure that the Spigot Adaptor is
firmly located onto the Base Housing and the shutter is still securely fastened and fully functional.
7. Set-up the appropriate speed selection and other features as outlined in
Section B SETUP.
8. Using the Base Housing as a template, mark the fixing hole centres on the wall, carefully sliding the spigot
into the Wall Liner. Secure the Base Housing into position using the screws and fixings provided ensuring the
Skirt is located correctly into the Base Housing (Fig 3)
9. Ensure the Impeller rotates freely.
10. Select and follow the appropriate wiring diagram in
Section C WIRING.
12. Replace the inner grille.
Replace the front panel.
13. Switch the mains power supply on and check the fan is operating correctly.

SETUP
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM
THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.
1. SELECTING THE CONSTANT TRICKLE OPTION -
Switch dip switch 2 into the ON position to activate the
constant trickle operation. To disable the constant trickle option, move dip switch 2 into the OFF position (Fig. 6).
2. SELECTING THE TRICKLE SPEED (if enabled)
This will determine the speed at which the fan will run continuously if the constant trickle speed option is enabled
(1 above).
•
Low trickle speed – Switch dip switch 1 into the OFF position (Fig. 6).
•
High trickle speed – Switch dip switch 1 into the ON position (Fig. 6).
3. SELECTING THE INSTALLATION RUNNING MODE
This will determine the speed at which the fan will run when activated by either the Pull-cord/LS line/Humidity/PIR.
•
Wall mode – Switch dip switch 3 into the OFF position (Fig. 6)
•
Ducted mode – Switch dip switch 3 into the ON position (Fig. 6)
4. SELECTING THE DELAY-ON OPTION
(HT model)
- Switch dip switch 4 into the ON position to activate the
delay-on feature. This will prevent the fan from going to boost for approximately 2 minutes. If the Switch Live is
disconnected (switched off) within this period the fan will not boost. If the Switch Live is still active after the period
the fan will boost. (Fig. 6).
5. TIMER ADJUSTMENT ( HT model)
The overrun time period is factory set to 15 minutes. The overrun time period may be adjusted from 5-30
minutes by altering the adjuster on the control PCB [T] (Fig. 6).
i.
To REDUCE the operating time, turn the adjuster [T] ANTI-CLOCKWISE (Fig. 6).
ii.
To INCREASE the operating time, turn the adjuster [T] CLOCKWISE (Fig. 6).
6. HUMIDITY ADJUSTMENT (HT model)
The fan’s Humidity Set-Point is factory set to switch the fan on at 72%RH (Fig. 6).
i.
To LOWER the Set-Point, turn the Humidity Adjuster [H] ANTI-CLOCKWISE. This makes the fan more
sensitive to RH%, i.e. the fan will come on at a lower RH% (Fig. 6).
ii.
To RAISE the Set-Point, turn the Humidity Adjuster [H] CLOCKWISE. This makes the fan less sensitive
to RH%, i.e. the fan will come on at a higher RH% (Fig. 6).
IMPORTANT
On first power up, the fan will run through its initialization routine.
On
HT
models the fan will switch on and off during this routine (Including the LED)
Once complete after approximately 2 minutes, the fan will run as normal.
