been tested at the end of the manufacturing process.
We recommend that you check the following when receiving this product:
• That it is the correct size and model.
• That the details on the rating label are those you require; voltage, frequency, performance.
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.
Electrical Connection
• Before Installation and Wiring ENSURE THE MAINS ELECTRICAL SUPPLY IS DISCONNECTED!
• 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%).
• The SILENT MV 160/100 standard fan (non-Timer) is fitted with single-phase 2-speed motor. For
connection using the two speed selection switches REGUL-2 or COM-2, follow wiring diagrams (Fig.
2). All motors are also 100% speed controllable via electronic voltage regulating speed controllers.
For connection using a REB single phase speed controlled, follow wiring diagrams (Fig. 3).
• The SILENT MV 160/100 “T” fan is fitted with single-phase 1 –speed motor and an electronic timer
adjustable from approx. 1 minute up to 30 minutes. For connection, follow wiring diagram (Fig. 4).
• Before operation, check all connections are correct and there are no obstructions to the airflow.
• On connecting the electrical supplies ensure the direction of rotation and airflow corresponds with
the direction airflow / rotation arrows (sited on unit).
Maintenance
• Before inspection or repair, ensure that the unit is disconnected from the mains electrical supply.
• The fan impeller should be cleaned at least once (1) a year to ensure trouble free operation.
• Do not clean the unit with strong detergents or cleaning fluids. Use a damp (not wet) cloth only
for cleaning.
