Before installing the product check the following points: (1) the fan impeller turns freely and (2) there are no
obstructions to the airflow.
All models include a robust mounting curb which enables easy and quick installation of the fan.
Ductwork connection should be made with duct tape or duct fast-clamps (available through your local stockist)
to ensure a good seal and secure connection.
ELECTRICAL CONNECTION
All TH series fans operate from a standard 120V 60Hz A.C electrical supply. All wiring must be carried out in
accordance with National Electrical Code and all applicable state and local buildings codes.
Electrical connections should be made in accordance with the following diagrams:
• Motor without Speed Controller
• Motor with Speed Controller
MAINTENANCE
IMPORTANT: BEFORE CARRYING OUT ANY MAINTENANCE OR SERVICING, ENSURE THE UNIT IS
DISCONNECTED FROM THE MAIN ELECTRICAL SUPPLY.
All TH series exhaust fans incorporate sealed for life bearings and therefore do not require any lubrication. We
would recommend inspection of the product at least once every twelve (12) months to avoid the excessive
accumulation of dust and dirt on the impeller (more frequent inspections may be required depending on
usage). To inspect the unit, disconnect from electrical supply and remove from curb. If any debris is evident
on the impeller clean with a damp (not wet) cloth. DO NOT USE any detergents or abrasive materials for
cleaning.
