ROUTINE INSPECTION/MAINTENANCE
THIS MUST BE UNDERTAKEN BY A COMPETENT PERSON.
ISOLATE UNIT FROM ELECTRICAL SUPPLY AND ENSURE THAT IT CANNOT BE ACCIDENTALLY
TURNED BACK ON.
1.
We recommend that after three months the fan should be inspected and cleaned to remove deposits on
the impeller or motor. Thereafter, it should be checked and cleaned periodically as experience dictates,
or at least twice a year.
2.
If a build up of dirt/deposits is evident then this should be carefully cleaned off. Please take care not to
damage the fan or affect the balance of the impeller motor assembly (balance weights may be fitted to
the impeller).
3.
The fan motors are fitted with 'sealed for life' bearings and should not require maintenance under normal
circumstances.
Wiring Diagrams:
Important Notes:- The electrical circuit must be protected with an all pole isolator having a minimum of 3mm
contact separation with suitable fuses or circuit breaker.
For ducted applications the Thermal Protector (TB) must be connected into a control circuit in order to ensure that the
fan cannot restart before the fault condition is cleared and the circuit manually reset.
(Refer to table below, for the relative wiring diagram – each fan has a wiring label within terminal box)
