Wiring the fan correctly...
Due to our policy of continuous innovation and improvement EnviroVent reserves the right to
alter products specication and appearance without notice.
You are about to install a product that is designed to outlast the life-cycle of the building. Once installed
the unit will operate continuously for 5 years and beyond without a major service. Please therefore ensure
that this product is treated with care and installed properly i.e. for the life of the building. If the unit is
mishandled you might break it! This invalidates the warranty.
And remember, if you have any problems please call our dedicated Technical Team. We are always
pleased to help and in an emergency will come out to site quickly, completely free of charge.

The connection into the fan MUST be a exible
cable and NOT solid core twin and earth, if the fan
is mishandled or a solid core twin and earth cable
is forced into the terminals you WILL break it, this
will invalidate the warranty.
If it is necessary to use twin and earth you must
not take it into the fan. Use a terminal block to
make the connection between the exible cable
supplied with the fan and your solid core twin
and earth cable. 12V D.C - Red wire on fan must
connect to red wire on SELV unit.
Place the cables inside the void in the back of the
back carcass next to the cable gland and secure
the fan to the wall securely.
IMPORTANT: The black grommets and sticky pad
provided must be tted in this unit. Not using these
items will jeopardise both the IP rating and the
warranty.

This fan is designed for easy cleaning and long life.
Keep this user guide handy. The fan has been set by the
installation engineer to suit your kitchen or bathroom
application. Your EnviroVent Filterless Extract Fan
has been designed to improve air quality and reduce
humidity levels in kitchens and bathrooms to help
resolve the condensation and mould problems which
can eect dwellings in winter.
ENERGY USE
Your EnviroVent Filterless Extract Fan uses the
lowest possible energy. To be used as a guide only*.
• On background trickle ventilation the unit will
use approximately 2 watts of energy - 50 times
less electricity than a 100W light bulb = £2.41 per
year.
• On bathroom boost mode for 2 hours and trickle
mode for 22 hours per day the unit will use
approximately 7 watts of energy = £3.18 per year.
Remember! The above low running costs can be
reduced on humidity tracking.
*Electricity suppliers have dierent rates - All costs
are based on an electricity cost of £0.15 per unit
(kWh) as of September 08.
HOW IT WORKS
The EnviroVent Filterless Extract Fan works in a
constant trickle mode to create background ventilation
to maintain a healthy environment.
Vapour tracking
As standard the unit is tted with vapour tracking
(except for 2 speed models, see below). The fan senses
the amount of moisture being created in the room
which causes the fan to increase in speed to match
the rising humidity and reduce in speed to match falling
humidity. This intelligent function reduces your energy
costs, wear and tear on the motor and ensures a long
quiet life.
Pullcord
All units are tted with a pullcord override for odour
control (if remote, see below). In the event that you
wish to activate the fan to full power in conditions of
low humidity simply pull on the pullcord and the fan will
boost to maximum extraction rate.
OPTIONS
Remote control
Remote control override for odour control. In the
event that you wish to activate the fan to full power
in conditions of low humidity simply press the remote
control boost switch and the fan will boost to the
maximum extraction rate for 3 to 4 minutes before
returning to the trickle extract rate.
2 Speed Version
The unit is also available in a two speed conguration,
without vapour tracking. These units run at a constant
trickle or at boost speed as required by the user.
Remote Switch Wire
The unit is available with a remote switch wire. On these
units the boost switch may be located up to 3 meters
away from the unit.

IMPORTANT
Be sure to have read and understood these
instructions before beginning the installation
process.
This fan operates on 12 Volts D.C.
DO NOT CONNECT TO MAINS. The fan must be
connected to the SELV (12V D.C) power supply/
spur unit enclosed.
Please note that the unswitched fuse spur is used
on the power supply unit. This does not aect the
performance of the unit.
SAFETY AND RECOMMENDATIONS

and the current IEE Wiring Regulations 17th edition
(BS7671) or the equivalent standards for your
country. The nal installation should be examined
and tested by a qualied electrician.

permanent electrical supply.
DO NOT REMOVE OR TAMPER WITH ELECTRONIC
