8.0 SETTING TO WORK
Ensure that all mechanical and electrical connections and fixings are
secure and that inlet and outlet ductwork is free of any obstruction or
debris.
Briefly switch the fan on/off to ascertain correct direction of impeller
rotation, compare with the rotational label fitted and correct if
necessary.
To change the direction of rotation on the 3 phase motor, inter-change
any 2 incoming supply phases at the motor terminal box.
Complete the test by running the fan for approximately 15 minutes,
taking and comparing voltage, full load and starting currents with the
fan rating label. Monitor flexible connections to ensure no leakage and
AV mounts for correct alignment.
9.0 MAINTENANCE
The first maintenance should be carried out three months after
commissioning and thereafter at twelve monthly intervals. These
intervals may need to be shortened if the unit is operating in adverse
environmental conditions, or in heavily polluted air.
