FAN MAINTENANCE

• Fan maintenance should be performed by experienced and trained staff only.
• The fan should be inspected and cleaned at least once per year.
• Prior to commencing any maintenance or repairs, make sure the fan is disconnected from the power source.
• Proceed to maintenance and repair after any fan rotation is stopped.
• Observe staff safety regulations during the maintenance and repair works.
• The fans features a heavy-duty ball bearing design. The motor is completely sealed and free of maintenance.
• Detach the fan from the unit.
• The impeller should be particularly checked for built-up material or debris that may cause an imbalance. An excessive imbalance may lead to
accelerated wear on the motor bearings and cause vibration.
• Clean the impeller and inside the housing with a mild detergent and a damp soft cloth.
• Do not use high-pressure cleaners, abrasive materials and sharp tools or caustic solvents that may scratch or damage the housing and impeller.
• Do not plunge the motor in any fluid while cleaning the impeller. Make sure the impeller's balance weights are in place.
• Make sure the impeller is free of any obstacles.
• Install the fan back into the unit. Connect fan power and control signals.
• In case the fan does not automatically start up or stop after maintenance, contact the manufacturer. The malfunction of the fan can be identified
by the pressure in the system (when pressure switches are connected) or by the protection signals of the fan unit.
Prior to commencing any maintenance or repair works, make sure the unit is disconnected from the power source.
