6.5. FANS MAINTENANCE
Fans get dirty, which reduces their efficiency.
Prior to commencing any maintenance or repair works, make sure the unit is disconnected from the power source.
Do not use water.
•
Observe staff safety regulations during the maintenance and repair works.
• Make sure the fan ball bearings do not make excessive noise.
• The motor features a heavy-duty ball-bearing design. The motor is completely sealed and grease-free.
• Detach the fan from the unit.
• Make sure the impeller is in balance.
• 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.
• If necessary, clean fan housing section of the unit.
• 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). In case of any fault in the fan motor, a notice will appear on the control
panel.
6.6. ELECTRICAL HEATER MAINTENANCE
•
For electric air heaters, check that they are securely fastened, that the wiring connections are not loose and that the heating elements are not
folded. They may be bent due to uneven heating when uneven air flow passes through them. Check the heater for unnecessary items and
contamination of the heating elements, as this can cause unwanted odours and, in the worst case, dust can ignite. The heating elements can
be cleaned with a vacuum cleaner or a damp cloth.
