9. POSITIONING 14. FAN WIRING
All units should be mounted on a completely flat base.
Mounting brackets are provided with the units.
10. DUCT CONNECTIONS
Adjoining ductwork should always be independently supported to avoid undue stress on the unit casing. Impellers
are statically and dynamically balanced, anti-vibration mounts and fast clamps are available to suit.
11. ACCESS
All units are designed with easily removable components for maintenance purposes. Sufficient room should be
kept to allow components to be withdrawn.
12. ELECTRICAL WIRING
Electrical supply must be fully isolated before attempting to affect any work on the unit.
All wiring should be carried out by a competent electrician and should comply fully with the current I.E.E. Wiring
regulations.
The electrical supply must be as stated on the nameplate.
When the wiring is complete, check for free & correct rotation of the fan impeller.
13. MAINTENANCE
HALF YEARLY
The fan impeller should be carefully cleaned with a brush. This will prevent the impeller from becoming unduly
dirty and become unbalanced.
