"RA10/4LV" - RECESSED AXIAL FANS
INSTALLATION and OPERATING INSTRUCTIONS
PLEASE READ THE FOLLOWING INSTRUCTIONS VERY CAREFULLY BEFORE USING
THE PRODUCT. THE MANUFACTURER WILL NOT BE HELD RESPONSIBLE AND
DECLINES ANY AND ALL LIABILITY FOR DAMAGE CAUSED TO PERSONS OR PROP-
ERTY DUE TO IMPROPER USE WITH REFERENCE TO THE PRECAUTIONS OUTLINED
IN THIS MANUAL.
THIS MANUAL MUST ALWAYS BE READILY AVAILABLE.
RA10/4LV with DRHLV
4"/10cm axial fan for installation into walls, ceilings or single pane or double glazed windows up to
28mm thick using optional Window Kit.
This is a
LOW VOLTAGE
model and
MUST
be installed using the transformer provided.
This fan works in conjunction with a Dynamic Remote Humidistat, which is also a SELV (Safety Extra
Low Voltage) product.
The adjustable, humidistat is pre-set so that the fan will operate automatically when the moisture con-
tent in the room reaches 70% R.H. The fan will continue to operate until the Relative Humidity falls
below the pre-set level and the timer has completed the over-run period. There is a trimmer inside the
humidistat which allows it to operate at a higher or lower level of humidity. The Humidistat can be
adjusted so that it starts to operate from a minimum of 40% to a maximum of 100%. All versions with
Humidistat incorporate a controlled temperature set-back allowing the humidistat to take into account
variations in the ambient temperature and to avoid the fan switching on unnecessarily. This reduces fan
operation at night.
