Wire the Transformer
MAKE SURE THE MAINS SUPPLY IS ISOLATED
26. If surface mounting, route Low Volt (7V/12V ac) and mains supply cables through the appropriate knockouts into their
respective compartments. When using the side entries a hole suitable for the cable size should be made centrally in
the rectangular section.
27. Locate the cables in the cable clamps and make connections as shown in J. Ensure all connections are tight.
28. For fixed wiring circuits the protective fuse for the appliance must not exceed 5A.
29. Re-fit fuses and switch on supply.
Using the fan.
LV100R / LV100S Only
Operate the fan using the on/off switch (not supplied). Repeat to switch off.
LV100TR / LV100TS Only
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 transformer control “T” clockwise to increase and anti-clockwise to decrease – see Figure
H.
LV100PR / LV100PS Only
Operate the fan by pulling and releasing the cord. Repeat to switch off.
LV100HTR / LV100HTS Only.
The fan automatically adjusts to slow changes in natural humidity levels without operating the fan. If the humidity
levels increase at a rate slower than 5% RH in 5 minutes, up to the pre-set humidity level, the fan will not be triggered
by humidity. This is to prevent nuisance triggering of the fan. If humidity levels increase quicker than 5% RH in 5
minutes the fan will operate. When relative humidity drops the fan continues to operate for the adjustable time delay.
LV100HPTR / LV100HPTS Only.
Automatic mode
- The fan automatically adjusts to slow changes in natural humidity levels without operating the fan.
If the humidity levels increase at a rate slower than 5% RH in 5 minutes, up to the pre-set humidity level, the fan will
not be triggered by humidity. This is to prevent nuisance triggering of the fan. If humidity levels increase quicker than
5% RH in 5 minutes the fan will operate. When relative humidity drops the fan continues to operate for the adjustable
time delay.
Pull Cord operation
– Use the integral pull cord switch. When the fan is switched off, the fan continues to operate for
the adjustable time delay then goes into automatic mode.
LV100PIRR / LV100PIRS Only.
The sensor detects movement in the room and activates the fan. When movement is sensed, the fan will run for a
pre-set overrun period and any further movement sensed will re-start the sequence. This ensures that the room is
only ventilated during and immediately after use. When the fan is first installed it will run for the time set by the over-
run timer. After this time, if no movement is sensed the fan will go into stand-by mode.
All Fans
Re-fit the front cover by hooking in the top first, and then swing the cover down to clip into place.
Cleaning (recommended once a month).
1. Before cleaning, isolate the fan completely from the mains supply.
2. The fan should be periodically wiped clean in position with a damp, lint free cloth and mild
detergent.
3. Do not immerse the fan in water or other liquids to clean any other parts of the fan.
4. Do not use strong detergents, solvents or chemical cleaners
5. Allow fan to dry thoroughly before use.
6. Apart from cleaning, no other maintenance is required.
