(i) CAUTION: For General Ventilating Use Only. Do Not Use To Exhaust Hazardous Or Explosive
Materials And Vapors.

The POWERVENT series can be mounted in any orientation, horizontal or vertical, and is suitable for
numerous types of applications.
If the installation is made to rigid or flexible ducting, then it is recommended that the correct diameter
ducting be used to couple to the fan flanges. If it is necessary to bend the duct at the discharge of the
fan then the bend radius should be as large as possible.
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 bracket, which enables easy and quick installation of the fan.
See Figure (1) Installation Diagrams For POWERVENT Duct Fans.
Ductwork connection should be made with duct tape or duct fast-clamps (available through your local
HVAC wholesale supplier) to ensure a good seal and secure connection.
ELECTRICAL CONNECTION
All POWERVENT 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 electrical wiring diagrams shown in
Figure (2) Electrical Wiring.
MAINTENANCE
IMPORTANT: BEFORE CARRYING OUT ANY MAINTENANCE OR SERVICING, ENSURE THE
UNIT IS DISCONNECTED FROM THE MAINS ELECTRICAL SUPPLY.
All POWERVENT series exhaust fans incorporate sealed for life bearings and therefore do not requi-
re 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. To inspect the unit dis-
connect from electrical supply and remove from ducting. 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.
