Important Safety Information
• The installation should always be carried out in accordance with all current applicable Standards
to the country in which the product is installed.
• The installation should always be carried out by a suitably qualified and competent person (s).
• These fans are not for stand-alone use. They are designed to be incorporated in to ducted systems,
machines or where safe operation has been ensured by providing protection to moving parts.
• Do not use this product in, or to extract from, potentially hazardous or explosive atmospheres.
• If the extractor operates in a room with a boiler or any other type of appliance requiring air for
combustion, check that air replacement in lets are sufficiently sized.
• The extractor outlet must not be connected to a duct used to exhaust smoke or fumes from any
appliance that uses gas or any other type of fuel.
Installation
• This unit must not be installed outside, unless covered by a suitable weather proof enclosure.
• For installation a support bracket is provided with the extractor which allows the motor and
impeller assembly to be fitted or removed without dismantling the adjacent ducting.
• For installation, remove the motor and impeller assembly from its support bracket (Fig. 1).
• Fix the support bracket in position where the extractor is to be located.
• Connect the inlet and outlet ducting. In order to avoid losses in performance we do not recommend
that fan is used in conjunction with ducting of a lesser diameter that the fan connection spigots.
If the extractor is connected to flexible ducting, then the ducting must be expanded as much as
possible.
• The fan should be installed to ensure minimum vibration and noise transmission to surrounding
ductwork and building frames. Ant vibration mountings and sound attenuating accessories are
available. Please contact your local distributor.
• The fan should always be installed so that safe operation and maintenance can be ensured.
• Before installing the unit ensures the impeller is running freely and there are no obstructions to
the airflow.

• The electrical installation must include a double pole switch with a contact clearance or at least
3mm, correctly sized and in accordance with the electrical standards of the country of installation.
• Ensure that the voltage and frequency of the electrical supply match the information stated on the
Date Plate of the unit (maximum recommended tolerance of Voltage (V) and Frequency (Hz) ±5%).
