Switch-On; Maintenance - Woods EC BOX FAN Safety, Installation, Operation And Maintenance Instructions

5. SWITCH-ON

5.1 Only appropriately qualified personnel should switch-on the fan. Before switching on confirm that
the electrical supply is fully compliant with the requirement of the product as detailed on the motor
nameplate, that the product is correctly installed, all component parts and fixings are secure, safety
guards are in place and no loose items are present in the vicinity of the box fan.
5.2 Immediately after switch-on we recommend that the product is checked for smooth, low-vibration
running, that the current consumption is within the full load current specified on the nameplate, and that
the motor is not getting excessively hot. Check that the impeller is rotating in the correct direction. The
box fan must not be switched on and off in a manner that could cause overheating of the motor, and
could damage the insulation of the motor and the internal wiring to the motor.
