INSTALLING THIS UNIT, CALL US ON:
Safety
Read and understand these instructions before beginning
installation. The unit should be installed by a competent person.
Check there is space to fit the unit in your chosen location. As
standard it can be installed using 100mm or 125mm inside diameter
duct. With the optional adaptor, a 150mm duct can also be used.
The unit can be wall mounted as standard, or ceiling, recess, inline
and window mounted using optional kits (see page 15 for further
information). The unit cannot be wall mounted upside down (with the
electronic boards at the bottom) as this will void the warranty.
Ensure the operation of the unit does not affect the operation of open-
flue appliances. If you are unsure, please consult local regulations
or a qualified gas engineer. Consider the external cowl location in
relation to open-flues from appliances e.g. boilers. You must ensure
the cowl is positioned a minimum distance of 300mm away in all
directions.
In kitchens, if the unit is fitted above a cooker, it must be installed a
minimum distance of 1 metre above any hob, and not have a pullcord
fitted.
This unit is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities or lack of experience
and knowledge, unless they have been given supervision and usage
instruction by a person responsible for their safety.
Children should be supervised to ensure they do not play with the unit.
Cleaning and user maintenance must not be performed by children.

Electrical Connection
The unit must be able to be disconnected from the Mains supply
after installation. When wiring the unit to the Mains power supply,
a suitable local isolator must be incorporated in the fixed wiring in
accordance with the IET Wiring Regulations.
Connection to the fixed wiring must be made outside the unit in a
suitable location, following IET Wiring Regulations.
The power cable running into the cable gland must remain the
supplied flexible cable (not a solid core lighting and mains cable). If
any other type of cable is forced into the cable gland, the unit will be
damaged, voiding the warranty.
If the mains cable is damaged, it must be replaced by EnviroVent, an
authorized service agent, or a similarly qualified person in order to
avoid a hazard.
Do not remove or tamper with the electronic circuit boards inside the
product. The unit requires a continuous electrical power supply and
should not be wired through a light switch.
Wiring Regulations
All wiring must comply with Building Regulations and the current
IET Wiring Regulations (BS7671 in the UK) or equivalent standards for
other countries. The final installation should be examined and tested
by a qualified electrician.

About the Product
Function
The EnviroVent Filterless Extract Fan has been developed to improve
indoor air quality, reduce humidity levels in kitchens and bathrooms
and resolve condensation and mould problems. It is designed to
operate continuously for up to 5 years without a major service.
Humidity Tracking
As standard, the unit is fitted with Intellitrac®Technology to sense the
relative humidity in the room (not included on 2-speed variant). Once
above the setpoint, the fan speed will increase as humidity levels rise
and decrease as humidity levels fall. This intelligent function reduces
energy costs, motor wear, and ensures a long life for the product.
Pullcord
If your Filterless Extract Fan includes a pullcord, it can be used to
engage the maximum extraction rate for odour control. Pull down
on the cord to increase the unit to the maximum extraction rate. Pull
down again to decrease the unit back to the low extraction rate.
Cartridge Replacement
If necessary, the central cartridge can be exchanged for a replacement.
The removed cartridge can be returned to EnviroVent for recycling.
This allows the front cover, rear carcass and duct to remain intact
throughout the life of the property, eliminating the wasteful disposal
of non-biodegradable material to landfill sites.

Wireless Remote Control
When the button on the remote
control is pressed, the unit will
extract at the maximum extraction
rate for up to 15 minutes then return
to the low extraction rate. The high
extraction rate can be stopped early
if required, by pressing the button
on the remote control within the 15
minutes. (Remote control units do
not include a pullcord).
Wired Remote Switch
On these units, a wired boost switch
may be connected up to 3 metres
away from the unit. (This must be
a volt free contact – do not wire the
cable or switch into the Mains). When
the remote switch is activated, the
unit will operate at the maximum
extraction rate. It will remain at this
rate until the switch is deactivated.
Two-Speed Only
The unit is available in a two-speed
variant, without humidity tracking.
These units run at a constant trickle
or boost speed as required by the
user.
To pair additional remote-control
switches:
1. Turn the unit off at the isolation
point.
2. Restore power; for 20 seconds
from restart the unit will be in
pairing mode.
3. Press the remote button once
within the 20 seconds and the
control will pair to the unit.
4. Successful pairing is indicated by
a green light on the control.
Batteries
When the battery (CR2032 type)
requires changing, unscrew the
switch front cover. The battery is
located on the back of the cover. The
switch will remain paired with the unit
after battery replacement. Ensure the
new battery is inserted with correct
polarity, and the removed battery is
safely disposed of.
