Speed Control
4.2 Speed controlled versions of the unit feature a 3 position switch to operate
the unit.
Break In Period
4.3 The unit uses a belt to drive the fan from the motor. The belt tension
should be checked after the first 2-3 days use (48-72 hours usage) because
it will naturally stretch to its final length during this time. See maintenance
section bellow for details on how to adjust the belt tension.
IMPORTANT: Failure to adjust the belt tension after break in will lead to a
reduced life of your fan through pulley wear, motor wear and premature
failure of the belt. This is not covered under warranty.
WARNING: The fan(s) must be isolated from the power supply during
installation and maintenance.
5. Troubleshooting
5.1 If the fan is under-performing check the following:-
Belt tightness (see section 6)
5.2 If the fan is making unwanted noises check the following:-
Belt tightness (see section 6)
That the unit is square on even ground
5.3 If the belt continues to slip after tightening, it is possible the motor pulley
has become damaged. In this instance please contact your distributor for a
replacement pulley.
IMPORTANT: Most problems with the unit can be avoided by maintaining
the belt tension.

6. Maintenance
WARNING: The fan(s) must be isolated from the power supply during
installation and maintenance.
6.1 Only a suitably qualified and competent person may carry out
maintenance after the electrical supply has been isolated.
Internal Access
6.2 To access the internals of the fan, an 8mm hex head socket should be
used to remove the fixings around the wire guard. Removing the wire
guard is expected for maintenance and will not void your warranty.
6.3 Inspection of the fan at least once every 6 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.
6.4 All fastenings should be checked for tightness. In addition, all rotating
items should be checked.
6.5 Bearings are of the “sealed for life” variety and will not need a detail
inspection.
Belt Tension
6.6 Belt tension should be checked after the first 2-3 days use (48-72 hours
usage) and then periodically depending on use.
6.7 Allow 15-20mm deflection for the correct tension.
Please note over tensioning will dramatically aect the longevity of the
unit.
