Mount the external grille in the soffit
11. Align the grille centrally and squarely over the 100mm hole in the soffit and mark the positions of the two screw holes.
Drill the two holes and insert suitable fixings.
12. Attach the external grille to the outer end of the flexible duct. Use the self-adhesive foam strip to seal the duct to the
grille. Secure ducting to grille (see Fig. D).
13. From the outside feed the ducting through the hole until the grille is flush with the soffit. Secure the grille to the soffit
using the screws and fit the screw covers.
14. Pull the flexible ducting gently to the fan duct and cut it to length. Keep the ducting as straight as possible as this will
prevent loss in performance of fan. Secure over fan duct.
Wire the electrical connections.
15. Make sure the mains supply is isolated. Switch off the mains electrical supply and remove fuses.
16. Feed the cable to the terminal block. Wire the fan as shown in Figure H.
17. Connect the cable from the isolating switch to the electrical supply wiring.
SPEED SETTING
The fan is factory set to low speed, but has two speed settings for different applications. Select either high or low speed by
connecting the jumper between the centre and high or low speed pin on the jumper (see Figure G).
To adjust the over-run period turn the control (T) clockwise to increase and anti-clockwise to decrease – see Figure F.
Using the fan.
Operate the fan using an on/off switch (not supplied). Note – the fan may take up to 10 seconds to turn on once the
switch has been operated. When the switch is turned off, the fan continues to operate for the set time delay. To adjust
the over-run period, turn the control “T” clockwise to increase and anti-clockwise to decrease – see Figure G.
18. Re-fit the front cover by hooking in the top first, and then swing the cover down to clip into place.
