10. Troubleshooting
10.1 Should the unit trip out, check the motor current or connections as an
overload condition has occurred, indicating misconnection, faulty motor
or capacitor (on single phase models), or a jammed impeller.
10.2 If the unit airflow direction is incorrect at initial start-up, re-check the
electrical connections for the desired connection.
10.3 If the unit is slow to start or will not start, it is likely that the capacitor needs
replacing (on single phase models).
11. Maintenance
11.1 Inspection of the fan at least once every 12 months is recommended
to ensure that the motor, fan blades and supporting guards are clean.
Any build-up of dust and deposits on the blades, motor or guards should
be removed using a non-abrasive cleaner. Failure to keep the unit clean
can lead to overheating and damage which is not covered by the warranty.
11.2 All fastenings should be checked for tightness. In addition, all rotating
items should be checked.
11.3 Bearings are of the ‘sealed for life’ type and will not need a detailed
inspection.
