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.
• Observe staff safety regulations during maintenance and repairs.
• The motor features a heavy-duty ball bearing design. The motor is completely sealed and grease- free.
• Detach the fan from the unit.
• The impeller should be particularly checked for built-up material or debris that may cause an imbalance. Excessive imbalance may lead to ac-
celerated wear on motor bearings and vibration.
• Clean impeller and inside housing with mild detergent, water and damp, soft cloth.
• Do not use high-pressure cleaner, abrasives, sharp tools or caustic solvents that may scratch or damage the housing and impeller.
• Do not plunge the motor into any fluid while cleaning the impeller. Make sure the impeller's balance weights are not moved.
• 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 after maintenance does not automatically start up or stop, contact the manufacturer. 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.
Prior to commencing any maintenance or repairs, make sure the unit is disconnected from the power source.

fan connects to control board's X16, X2, X4 connectors. Smarty 4XV F2 fans can be disconnected by unplugging X32, X33 connectors located
on the fans housing.
Note:
• X2 and X4 are same for both fans.
