SAFETY REQUIREMENTS

The fan complies with the requirements according to the EU

norms and directives.

In case if a fan with the level of protection that corresponds to

the second distinctive number IPX4 is used in humid conditions,

it is necessary to provide additional protection in order to prevent

moisture access. Possible protection means:

1. If a fan is installed in a horizontal position, the duct length on

both sides should be not less than 1m.

2. In any fan position it is necessary to install a cap on the

suction branch tube.

Precautions must be taken to avoid the black-flow of gases into

the room from the open flue of fans or other open-fire

appliances.

NOTE: Installation and connection of the fan should be done by

a qualified person in accordance with the IEE wiring regulations.

Prior to connecting the fan to power supply, it is necessary to

make sure that there is no visible faults on the rotor, case, grid

and that there are no foreign items in air flow part of the case,

which may damage rotor's blades.

CAUTION: Do not use the fan in highly explosive environment.
