For fixed wire and circuits the protective
fuse for the appliance must not exceed 5A.

To adjust the overrun timer insert a small
screwdriver into the recess in the control
spindle and turn clockwise to increase and anti-
clockwise to decrease.

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 is factory set to approximately
20 mins, but can be adjusted between 2 mins and
30 mins by control T.
•
Both controls are adjustable. Turn the controls
clockwise to increase RH or time, and anti-
clockwise to decrease.

If wiring from above cut out the cable entry slot
marked on top of the front cover.

Fit the front cover by aligning it square to the duct
and pushing it onto the duct until the release
catches snap into the slots on the front cover.
Wiring the transformer H & I
MAKE SURE THE MAINS SUPPLY IS
ISOLATED.
1. If surface mounting, route 12V a.c. mains
supply cable through the appropriate knock-
outs into their respective compartments.
When using the side entries a hole suitable
for the cable size should be made centrally in
the rectangular section.
2. Locate the cables in the cable grips (mains
cable shown in
H
, and make the connections
shown in
I
).
3. Ensure all connections are tight.
4. Switch off the mains electrical supply and
remove fuses.
5. 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.
6. Refit fuses and switch on supply.
Using your fan
LV100 only
•
Operate the fan using on/off switch (not
supplied). Repeat to switch off.
LV100PC only
•
Operate the fan by pulling and releasing the
integral pull cord.
•
Repeat to switch off.
LV100T only
•
Operate the fan using the on/off switch. When
the switch is turned off, the fan continues to
operate for the adjustable time delay period.
LV100HTA 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.
LV100HTAP 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.
•
Manual mode – Use the integral pull cord switch.
When the fan is switched off, it goes into
automatic mode after the time delay. Light
indicates when the fan is operating in manual
mode.
LV100PIR 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 there will be a stabilising
period of approximately five minutes. During this
time the fan will run for up to two minutes.
Cleaning (recommended once a month)
A QUALIFIED ELECTRICIAN SHOULD CARRY
OUT ALL CLEANING
1. Before cleaning isolate the fan completely
from the mains supply.
2. Remove the front cover by pressing the release
catches located on the sides of the unit with a 3mm
screwdriver whilst pulling the front cover forward
L
3. To clean the front cover either wipe it with a
damp, lint free cloth or wash it in warm soapy
water. Thoroughly dry the front cover and re-fit.
4. Do not immerse the fan in water or other liquids
to clean any other parts of the fan.
5. Never use strong solvents to clean the fan.
6. Apart from cleaning, no other maintenance is
required.
