Fan Settings.
SPEED SETTING
The fans are factory set to low speed, but have 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 F)
C4TSR Only.
To adjust the over-run period turn the control (T) clockwise to increase and anti-clockwise to decrease – see Figure D.
C4HTSR Only – see figures D and F.
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 at 15 minutes but can be adjusted from 30 seconds to 30 minutes by control T.
Turn the controls clockwise to increase RH or time and anti-clockwise to decrease.
Using the fan.
C4SR Only
Operate the fan using the on/off switch (not supplied). Repeat to switch off.
C4PSR Only
Operate the fan by pulling and releasing the cord. Repeat to switch off.
C4TSR Only
Operate the fan using an on/off switch (not supplied). 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 F.
C4HTSR 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.
External operation - Use the external on/off switch. When the fan is switched off, the fan continues to operate for
the adjustable time delay then goes into automatic mode.
All Fans
Re-fit the front cover/baffle assembly by hooking in the top first, and then swing the cover down to clip into place.
If surface mount wiring, ‘break out’ the thin wall section in the front cover prior to re-fitting (see figure E). The miniature PVC
trunking must then be sealed against the front cover to prevent any water ingress.
Replacing Square Baffle with Round Baffle (Figs. G1 and G2)
Ensure fan is isolated from supply before performing this action.
1.
Remove Square Baffle/Cone assembly from Fan Front Cover by twisting anti-clockwise until all three support legs are
released from clips.
2.
Fit Round Baffle/Cone assembly by aligning clips on baffle with legs on Front Cover and rotating Baffle Clockwise until
all three clips engage and are retained on Front Cover.
Cleaning (recommended once a month).
1.
Before cleaning, isolate the fan completely from the mains supply.
2.
Remove the front cover/baffle assembly by depressing the latch on the underside of the cover
and pulling off the front cover / baffle from the bottom.
3.
To clean the front cover/baffle assembly, either wipe it with a damp, lint free cloth or wash it
with warm soapy water. Thoroughly dry the front cover and refit.
4.
Do not immerse the fan in water or other liquids to clean any other parts of the fan.
5.
Do not use strong detergents, solvents or chemical cleaners
6.
Allow fan to dry thoroughly before use.
7.
Apart from cleaning, no other maintenance is required.
