1.0 SAFETY INFORMATION
• The device should not be used for applications other than those specified in this manual.
• After removing the product from its packaging, verify its condition. In case of doubt, contact
a qualified technician. Do not leave packaging within the reach of small children or people with
disabilities.
• Do not touch the appliance with wet or damp hands/feet.
• This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved. Children shall not play with the appliance.
• Cleaning and user maintenance shall not be made by children without supervision.
• Do not use the product in the presence of inflammable vapours, such as alcohol, insecticides,
gasoline, etc.
• If any abnormalities in operation are detected, disconnect the device from the mains supply
and contact a qualified technician immediately. Use original spare parts only for repairs.
• The electrical system to which the device is connected must comply with regulations.
• Before connecting the product to the power supply or the power outlet, ensure that:
- The data plate (voltage and frequency) corresponds to those of the electrical
mains.
- The electrical power supply/socket is adequate for maximum device power. If
not, contact a qualified technician.
• The device should not be used as an activator for water heaters, stoves, etc., nor should it
discharge into hot air/fume vent ducts deriving from any type of combustion unit. It must expel
air outside via its own special duct.
• Operating temperature: 0°C up to +50°C.
• The device is designed to extract clean air only i.e., without grease, soot, chemical or corrosive
agents, or flammable or explosive mixtures.
• Do not leave the device exposed to atmospheric agents (rain, sun, snow, etc.).
• Do not immerse the device or its parts in water or other liquids.
• Turn off the main switch whenever a malfunction is detected or when cleaning.

• For installation an omnipolar switch should be incorporated in the fixed wiring, in accordance
with the wiring regulations, to provide a full disconnection under overvoltage category III
conditions (contact opening distance equal to or greater than 3mm).
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or
similarly qualified persons to avoid a hazard.
• Do not obstruct the fan or exhaust grille to ensure optimum air passage.
• Ensure adequate air return into the room in compliance with existing regulations to ensure
proper device operation.
• If the environment in which the product is installed also houses a fuel-operating device
(water heater, methane stove etc., that is not a “sealed chamber” type), it is essential to ensure
adequate air intake, to ensure good combustion and proper equipment operation.
• Install the product so that the impeller is not accessible from the air outlet side as verified
by contact with the Test Finger (test probe “B” of the norm EN61032) in compliance with the
current safety regulations.
• Ceiling Installation
To guarantee the IPX4 degree of protection against moisture in case of ceiling installation,
use the appropriate ceiling mount kit, which is not included. Use only the rear entry hole for
supply cables. If there is a possibility of condensation along the air discharge duct, provide a
drainage system to prevent condensation from discharging into the environment through the fan
Attention: do not mount the product on the ceiling without this kit.
• Window Installation
In case of window installation, it is necessary to use the appropriate window kit, which is not
included. Attention: do not mount the product on the window without this kit.

3.10 Humidity Sensor & Timer Settings
The fan is equipped with a humidity sensor, whose threshold is
adjustable from 50% to 95% Relative Humidity via dedicated trimmer,
and with a timer which is adjustable from 0 to approx. 30 minutes via
dedicated trimmer (Figure 25).
The fan runs continuously at selected trickle speed (set by the jumper
switch combination (Section 3.9), increases its speed in case the
percentage of Relative Humidity exceeds the settable threshold, and
can anyway be boosted with a dedicated ON/OFF switch (or PIR, CO2…
sensor) or with a light switch (Figure 24). Trickle speed can be set to off
(Section 3.9).
To deactivate the humidistat function, turn the trimmer HY completely
clockwise.
Automatic humidistat operation: when the percentage of Relative
Humidity exceeds the settable threshold, fan speed automatically
increases to “comfort boost” speed, (intermediate between the selected
trickle speed and the boost speed). When the percentage of Relative
Humidity goes below the threshold, the fan continues to function at
“comfort boost” speed for a factory set period of time then returns to
selected trickle speed.
Operation with external switch: (Figure 24). When the external switch is
turned on, the fan is boosted (max speed). After the external switch is
turned off, the fan continues to run at boost speed for a settable period
of time, then it returns to selected trickle speed (or to “comfort boost”
speed in case automatic humidistat operation is on). The front cover LED
indicates when the external switch is on.
The over-run timer function is activated only if the external switch has
been on for at least 60 seconds.

6.0 END-OF-LIFE AND RECYCLING
Where possible components which can be largely recycled when the
product reaches its end-of-life have been used:
• Fans, motors, controls, actuators, cabling and other electrical
components can be segregated into WEEE recycling streams.
• Sheet metal parts, aluminium extrusion, heating/cooling coils and
other metallic items can be segregated and fully recycled.
• EPP, plastic ducting, nylon corner pieces, plastic heat exchangers,
packaging material and other plastic components can be segregated
into mixed plastic and widely recycled.
• Cardboard packaging, wood, and other paper components can be
largely recycled or fully processed in energy from waste centres.
• Filter Disposal: Cardboard framed filters should be fully processed
in energy from waste centres, contact your local civic amenity site /
household waste recycling centre regarding metal / wire framed filters.
• Remaining Items can be further segregated and processed in
accordance with the zero waste hierarchy. Please call After Sales
Support for further information on items not listed above.
Ensure that this product is made safe from any electrical / water
/ refrigerant supplies before dismantling commences. This work
should only be undertaken by a qualified person in accordance
with local authority regulations and guidelines, taking into
account all site based risks.
This product complies with EU Directive 2002/96/EC.
The symbol of the crossed-out dustbin indicates that this product
must be collected separately from other waste at the end of its
life. The user must, therefore, dispose of the product in question
at suitable electronic and electro-technical waste disposal
collection centres, or else send the product back to the retailer
when purchasing a new, equivalent type device.
Separate collection of decommissioned equipment for recycling,
treatment and environmentally compatible disposal helps to
prevent negative effects on the environment and on health
and promotes the recycling of the materials that make up the
equipment.
Improper disposal of the product by the user may result in
administrative sanctions as provided by law.
