03 Wiring
Wiring the fan correctly...
1. 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.
2. 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.
3. 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.
Electrical Assembly

device such as a fused spur should be
used, do not use a plug. The means of
disconnecting the unit from the mains power
supply must be incorporated in the xed

There must be a necessity to allow
disconnection of the appliance from the
supply after installation, unless the appliance
incorporates a switch complying with the

be achieved by incorporating a switch in the
xed wiring in accordance with the wiring
regulations.

05 About The Unit
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.
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.

05 About The Unit
ENERGY USE
The EnviroVent Filterless Extract Fan uses
award-winning Ultra Low Watt motor
technology to give the lowest running
costs of any domestic extract fan. It uses
only a minimal amount of electricity whilst
eliminating stale and moist air from the
home.
This gives an annual running cost of only
£1.97 based on an electricity cost of £0.15
per unit (kWh) and a two hour ‘boost’
per day. In addition, the Filterless Extract
Fan is guaranteed for 5 years and has no
maintenance requirement during this period
saving both time and money for the user.
