6.2 Start Up Procedure
Ensure that the impeller rotation follows the label arrow indicator on the casing. Should the direction be incorrect on three phase units, reverse any two of the supply leads. Care should be taken to set correct rotation as incorrect rotation may result in damage to the motor. Equipment should be run for approx. 30 minutes to ensure correct operation. If any fault occurs, the equipment should be switched off. Do not re-start until the fault has been rectified.

7.0 SPECIFIC COMMISSIONING AND SERVICING REQUIREMENTS
Motors for Smoke Extract Fans
Exposure temperature/time: 300C for 2 hours / 400C for 2 hours
These motors are used to provide a SAFETY FUNCTION for people in the event of fire in public premises or in the home: they are therefore subject to strict constraints concerning their operating and maintenance.
Operating Constraints
i. Check on the nameplate that the selected motor corresponds to the maximum exposure temperature and duration.
ii. Non ventilated motors MUST be placed in the airflow from the driven fan. Ventilated motors can be placed outside the flow.
iii.AFTER THE MOTOR HAS BEEN SUBJECTED TO ONE EMERGENCY DUTY OPERATION, IT MUST BE REPLACED.
iv. With variable speed control. Ensure that the maximum speed never exceeds the speed of the motor supplied by the mains and that the delivered power corresponds to the previous definitions.
These qualifications ensure the qualification of the driven fan by the manufacturer.

Maintenance Constraints
Regular service visits must be performed on the installation AT LEAST EVERY 6 MONTHS, incorporating the following checks:
i. Checking insulation resistance (R>100 MOhms, 500V DC)
 If the drain holes are blocked, open them to eliminate any accumulated condensation.
 If R<100 MOhms, dry the stator in an oven and check the insulation resistance. If the fault persists, replace the stator.
 The stator must be replaced 5 years after installation or after 20,000 hours of operation.
ii. Cooling check
 Ensure there is no dust or grease in the entire ventilation circuit (housing fins, motor cover/fan if fitted driven fan).
 Ensure the motor runs normally when switched on for a few minutes.
iii. Bearing check (C3 or C4 play) Run the motor during each maintenance visit. When the motor is cold, a high level of noise is caused by the texture of the grease. This does not indicate a bearing fault.
iv. S2 duty only: The bearings must be replaced by an identical type every 5 years. Ensure the motor runs normally when switched on for a few minutes.
v. Fixing Check During regular maintenance, check all fixtures and fittings to ensure they have remained secure and in good working order.
S1 duty and Emergency in S2 duty: a) Permanently greased bearings. 300C or 400C range; replace on 2 pole motors after 10,000 hours of operation and on motors with 4 poles or more after 20,000 hours.
b) Regreaseable bearings The information on the motor nameplates must be strictly respected (grease quantity, grease quality and regreasing frequency). The bearings must be replaced after 20,000 hours of operation.
