CLEANING & MAINTENANCE

For quiet and efficient operation, long life, and attractive appearance — lower or remove the grille and vacuum interior of the unit with the dusting brush attachment.
The motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace the motor with the exact service motor. The impeller should also be replaced.

OPERATION

The control box, located inside the fan housing, has three separate adjustments.

1. The low airflow knob adjusts the lower airflow from 40 CFM up to the airflow rate of the high fan speed determined by the toggle switch setting. The fan will not work when the knob is turned between OFF-40CFM. Factory set OFF.
   

2. The time delay knob is adjustable from 5 to 60 minutes and will switch the fan to the low-speed setting after the switch II is turned OFF for the set period of time. The time delay will NOT work when the knob is turned between OFF-5mins, the fan will turn to low speed immediately after the switch II is turned OFF. Factory set OFF.

3.  The toggle switch will adjust the upper fan speed setting from 80 to 140 CFM. Factory set 110 CFM.

Turn the switch I (according to the CONNECT ELECTRICAL WIRING section on page ? of this instruction manual) ON

• The fan will run at the certified airflow rate if the switch II is ON
• The fan will run at the user-adjustable airflow rate if the switch II is OFF

To Use Fan Time Delay Airflow Rate Change

1. Turn the switch ON
2. Turn the switch II ON — Fan will run at the certified airflow rate

2. Extend the hanger bars to the width of the framing.
   Position the ventilator with the bottom edge of the hanger bar tabs flush with the bottom edge of the framing, holding the ventilator in place. Secure hanger bars to framing using one screw on each end of the hanger bar. Select a proper hole and secure the hanger bars together using one screw

3. Install Round Ductwork
   Connect the round ductwork (not included) to the damper/duct connector, and run the ductwork to a roof or wall cap (not included). Using tape (not included), secure all the ductwork connections so that they are airtight

Connect Electrical Wiring

Run 120V AC house wiring to the location of the fan. Use only UL- approved connectors (not included) to attach the house wiring to the wiring plate. Refer to the wiring diagram above, and connect the wires.

Install Grille
