OPERATIONS
TIMER ADJUSTMENT on SDF 100TBLV
Isolate the power supply. Remove the transformer cover. The timer adjustment is clearly marked. Turn the adjuster anti-clockwise to reduce
the over-run time and turn clockwise to increase the over-run time. The approximate range of the timer is 2 minutes to 30 minutes.
TIMER ADJUSTMENT on SDF 100HTBLV
Isolate the power supply. Remove the fan cover. The timer adjuster is situated at the right hand side. Turning the adjuster clockwise will
increase the over-run time. The approximate range of the timer is 2 minutes to 30 minutes.
HUMIDITY ADJUSTMENT on SDF 100HTBLV
Isolate the power supply. Remove the front cover of the fan and the adjustment of the humidity control is done using a fine tipped
screwdriver. Turn adjuster clockwise for less sensitivity and anti-clockwise for increased sensitivity. Adjustment is from 50% RH and
the range is approximately 50% to 90% RH. Condensation/Humidity controls are designed to switch an extractor fan on when the room
humidity exceeds a pre-set level. In order to achieve this the humid air must invade the sensor housing. This process can take some
time and when the room is in use this delay may cause some concern, also the sensor cannot detect smells or smoke. Therefore, we
recommend that fans with humidity controls should be wired up with manual (switch live) operation.
FITTING WINDOW FAN (Using SDF901WFK)
1. Cut hole in window 127mm (5”)min. size 140mm (5
1
/2”) max size -
this is probably a job for a glazier.
2. Remove the four fan clamp screws holding the inside and outside
halves together.
3. Hold the cowl on the outside of the window and insert the fan into the
hole from the inside, making sure not to displace the weather seal in
the process.
4. Replace the fan clamp screws and tighten evenly.
NOTE:
Do not over-tighten as this may break the glass.
MAINTENANCE
Isolate from power supply before commencing work.
TRANSFORMER
Maintenance free but the outer cover may be cleaned with a damp cloth.
FAN
The outside of the unit may be wiped clean with a damp cloth. Once a year
the front cover should be removed and the inside dusted with a soft brush.
NOTE:
If the fan unit is fitted to an uneven surface
such as fluted glass it may be necessary to
use some silicone bathroom sealer to ensure
that the discharge cowl is weather-proof.
