Preparing the fan for installation.
Remove the front cover by removing the screw from the underside of the cover and pulling off the cover from the bottom
corners first.
Remove the electrical cover by removing the 2 screws.
Mount the fan in the hole. If working above ground floor level, safety precautions must be observed.
If installing in a wall or ceiling.
Mark the position of the backplate.
1.
Hold the backplate so that the word “TOP” marked on it is orientated correctly.
2.
Carefully insert the lip into the wall duct/ceiling.
3.
Adjust the position of the backplate until it is level.
4.
Mark on the wall/ceiling the positions of the fixing holes in the backplate.
5.
Remove the back plate from the ducting.
6.
Drill screw holes in these positions if necessary, and fit wall plugs if necessary.
Mount the backplate.
1.
If installing in a ceiling, appropriate termination ancillaries are required. Follow instructions provided.
2.
Remove knockout. Feed the mains cable through the cable entry hole in the back plate to the terminals.
3.
Insert the lip of the backplate into the wall duct/ceiling as before.
4.
Fasten the backplate to the wall/ceiling using appropriate fasteners – see Figure C.
If using screws, do not over tighten.
The fans may also be fixed to the interior of the ceiling using the clamping brackets. Tighten the screws until the fan is firmly
fixed within the hole - see figure D.
Wire the electrical connections
.
1.
Make sure the mains supply is isolated,
2.
Wire the fan as shown in Figure E; check the fan model to diagram, feeding the cable to terminal block.
3.
Switch off the mains electrical supply and remove fuses.
4.
Connect the cable from the isolating switch to the electrical supply wiring.
For fixed wiring circuits the protective fuse for the appliance must not exceed 5A.
Setting the fan.
All Fans - Setting the Speed
All fans have the choice of 3 speeds of extraction, which is to be set at installation:
Speed 1 – suitable for 6l/s
Speed 2 – suitable for 8l/s
Speed 3 – suitable for 15l/s
To set the required speed, set the switches to the positions shown in Figure F (these are the 3 switches marked 4, 5 and 6
above them).
All Fans - Setting the Trickle Speed
All fans can be set so that they provide constant trickle extraction suitable for 6l/s.
To set the trickle speed to ON, set the switch shown in Figure F (this is the switch marked 1 above it) to the DOWN position
(the side of the switch marked ‘ON’).
To set the trickle speed to OFF, set the switch shown in Figure F (this is the switch marked 1 above it) to the UP position
(away from the side of the switch marked ‘ON’).
Setting the Delay Start – SLDC100 / SLDC100PC / SLDC100T / SLDC100HT Only
These fans can be set so that there is a 2-minute time delayed start.
To set the delay start to ON, set the switch shown in Figure F (this is the switch marked 3 above it) to the DOWN position
(the side of the switch marked ‘ON’).
To set the delay start to OFF, set the switch shown in Figure F (this is the switch marked 3 above it) to the UP position (away
from the side of the switch marked ‘ON’).
SLDC100T Only
The over -run timer can be adjusted up to 30 minutes by control T.
To adjust the over-run period turn the control (T) clockwise to increase and anti-clockwise to decrease – see Figure H.
SLDC100HT Only
The pre-set humidity operation is factory set at approximately 75% Relative Humidity (RH), but can be adjusted between
65% and 85% RH by control H.
The over -run timer can be adjusted up to 30 minutes by control T.
Turn the controls clockwise to increase RH or time and anti-clockwise to decrease – see Figure H.
Note
The switch marked 2 above it is a factory set position and should not be changed.
For the SLDC100 range this switch should be in the UP position (away from the side of the switch marked ‘150mm size’). If
this switch is NOT in the correct position the fan will NOT achieve the required speeds.
