Instructions

(iii)The fire department is being called.

(iv)You can fight the fire with your back to an exit.

e)TO REDUCE THE RISK OF FIRE, ONLY USE METAL DUCTWORK.

If the installation is made to rigid or flexible ducting, then we should recommend the correct diameter ducting is 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 2 installation diagram for 99-NBQ duct fans.

Ductwork connection should be made with duct tape or duct fast-clamps (available through your local supplier) to ensure a good seal and secure connection.

Electrical Connection

All 99-NBQ series fans operate from a standard 120V 60Hz AC electrical supply. All wiring must be carried out in accordance with National Electric Code and all applicable state and local building codes.

Electrical connections should be made in accordance with the following diagrams: Figure 3 Electrical wiring.

Maintenance

IMPORTANT: BEFORE CARRYING OUT ANY MAINTE- NANCE OR SERVICING, ENSURE THAT THE UNIT IS DISCONNECTED FROM THE MAIN ELECTRICAL SUP- PLY.

All 99-NBQ series exhaust fans incorporate sealed for life bearings and therefore so not require any lubrication. We would recommend inspection of the product at least once every twelve (12) months to avoid excessive accumulation of dust and dirt on the impeller. To inspect the unit, discon- nect from electrical supply and remove the ducting. If any debris is evident on the impeller, clean with a damp (not wet) cloth. DO NOT USE any detergents or abrasive mate- rials for cleaning.
