Wiring the fan correctly...

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.
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.
Due to our policy of continuous innovation and improvement EnviroVent reserves the right to alter products
specication and appearance without notice.
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.

FILTERLESS INFINITY FAN
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 Innity 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 eect dwellings in winter.
HOW IT WORKS
The Filterless Innity 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.
N.B: When battery requires changing, unscrew the
switch front cover. The battery is located on the back
of the cover (CR2032) lithium coin battery). Switch
will remain paired with the fan even after battery
replacement.
2 Speed Version
The unit is also available in a two speed conguration,
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.
ENERGY USE
The EnviroVent Filterless Innity 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 Innity
Fan is guaranteed for 5 years and has no maintenance
requirement during this period saving both time and
money for the user.
