Installation Instructions
If working above Ground Floor level, appropriate safety precautions must be observed.
WARNING
EYE PROTECTION MUST BE WORN DURING ALL DRILLING AND CHISELLING OPERATIONS
Safety First
The Heat Recovery Ventilator is a ”SELV” (Safety Extra Low Voltage) ventilator which operates at 12 volts AC. Under no
circumstances must this be connected directly to the mains supply. Damage so caused is not covered by the warranty.
The low voltage used by the ventilator must be provided by the isolating transformer. A typical layout of installation is
shown below.
The Heat Recovery Ventilator can be used in any room which has an outside wall open to fresh air. It is particularly
useful in the bathroom, kitchen or laundry room where high levels of moisture are generated. It can also be used in the
lounge, dining room or any bedroom to provide a fresh air supply to reduce dust-mite, eliminate mould growth or
dampness and condensation and to provide warmed fresh air.

Isolating Transformer (Humidity sensor unit).
The humidistat monitors the humidity in the room and automatically switches the ventilator from continuous trickle
speed to boost if the humidity exceeds the set point e.g. when using the shower, cooking or doing the laundry.
The humidity level can be adjusted by turning the thumbwheel (as shown on page 2). We recommend that it is initially
set to number 6 on the scale, which is suitable for most locations. Turning the thumbwheel clockwise decreases the
sensitivity (fan in boost for shorter time) and anti-clockwise increases the sensitivity (fan in boost for longer time).
To prevent tampering with the setting after installation, the thumbwheel can be removed by carefully pulling gently
upwards. A blanking plate is supplied to seal the hole previously occupied by the thumbwheel.
If installed in a shower or bathroom the transformer/humidistat must be out of reach of anyone using a bath or shower.
We strongly recommend installation by a competent electrician.

Sitting the Ventilator
Do not install where ambient temperatures are likely to exceed 40 oC (104 oF).
◆ This electrical product, if installed in a shower room or bathroom, must be situated so that they cannot be touched
by the person using the bath or shower.
◆ When intended for use in possible chemical corrosive atmospheres, first consult GDA Applied Energy for
technical advice
◆ If installing in a room containing a fuel burning device which has a non-balanced flue, it is the installers
responsibility to ensure that there is replacement air to prevent fumes being drawn down the flue when ventilator
is operating up to maximum extract. Refer to building regulations for specific requirements. Exhaust air must not
be discharged into a flue used for exhausting of fumes from appliances supplied with energy other that electric.
Requirements of all authorities concerned must be observed for exhaust air discharge and intake flow rates.
a) Survey the property carefully and identify the best site for the ventilator. Condensation problems, dampness and
mould growth are stimulated by high levels of humidity, the source of which can be the bath/shower room,
laundry room, kitchen or possibly a damp wall.
Identify an area in the room with an outside wall which is clear of obstruction, both inside and out - check for
water and soil pipes, wiring and other obstructions before finalising your installation position.
b) Indicate the position of the core drill hole on the inside wall. If possible, mark it’s position on the outside wall too.
See if they look right. Remember that the Heat Recovery Ventilator is unique in that it both extracts stale, damp air
and blows in warmed fresh air. Make sure that steam from your cooker/hob or appliance is not blown away
from the fan.
