Product Usage Instructions

Follow the steps below for the typical installation of the ZB80L1 or ZB110L1 ventilation fan:

1. Place insulation around and over the fan housing.
2. Install the fan housing in the desired location.
3. Connect a power cable to the fan housing.
4. Keep duct runs short and seal gaps around the housing.
5. Install a roof cap with a built-in damper for ducting to the outside of the building.
6. Alternatively, use round elbows and a wall cap with a built-in damper for ducting.
7. Seal duct joints with tape.

Note : The ducting from the fan to the outside of the building significantly affects the air flow, noise, and energy use of the fan. It is recommended to use the shortest, straightest duct routing possible for optimal performance. Avoid installing the fan with smaller ducts than recommended. Insulating the ducts can reduce energy loss and inhibit mold growth. Existing ducts may not provide the rated airflow for the fan.

Operation

To Turn Fan ON
Turn the master switch ON. It is normal for this ventilation fan to take approximately 5 seconds to start running after it is turned on.

• Fan will run at the certified airflow rate if the mode
select switch is ON.
• Fan will run at the user-adjustable airflow rate if the
mode select switch is OFF.

To Use Fan Time Delay Airflow Rate Change

1. Turn the master switch ON.

2. Turn the mode select switch ON – fan will run at the certified airflow rate.

3. When the mode select switch is turned OFF, fan will continue to run at the certified airflow rate until the user-adjustable time delay has elapsed, and then will automatically change to the user-adjustable airflow rate.

   • **To Set the User-Adjustable Airflow Rate***
     Using a small, flat-blade screwdriver, carefully rotate the CFM adjustment until the arrow points to the desired airflow rate.

   • **To Set the User-Adjustable Time Delay***
     Using a small, flat-blade screwdriver, carefully rotate the TIME adjustment until the arrow points to the desired time delay, shown in minutes.
     The user-adjustable controls are located in one corner of the Fan Housing, behind the Grille.

   • To Turn Fan OFF
     Turn the master switch OFF.

   • To Operate Lights
     The fan and light can be operated independently, using separate switches. The light may be operated with a dimmer switch. See wiring diagrams

Cleaning and Maintenance

CAUTION

IN ORDER TO PREVENT MOTOR/CONTROL DAMAGE:

• DO NOT remove motor plug to stop spinning motor.
• Power must be disconnected (see WARNING at top left of this page) before motor plug is removed or inserted into control assembly.

To Clean

1. For quiet and efficient operation, long life and attractive appearance, remove Grille and vacuum interior of unit with a dusting brush attachment.
2. The Motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace the Control Assembly and Motor.

Troubleshooting

Symptom: Fan does not run.

• Check for an open fuse or circuit breaker in building’s service panel.

  • Check two (2) plug-in connections for Motor and its Control are seated firmly in place.

• Check that Blower Wheel spins freely.
  Symptom : Motion mode does not operate fan at certified air flow rate.

• Check two (2) plug-in connections for Sensor and its Control are seated firmly in place.
  Symptom: The fan runs erratically.

• Check that the Blower Wheel is firmly attached to the Motor shaft and both spin freely.
  Symptom: The fan seems noisy.

• Check that the back draft damper in the fan’s Duct Connector pivots freely. Screws used to attach the duct to the Duct Connector may be preventing the damper from opening.

• Check that the back draft damper in the wall or roof cap pivots freely. These dampers are sometimes mistakenly painted shut or obstructed by bird and insect debris.
  Symptom: The fan does not properly ventilate the room.

• For spot ventilation, turn both the master switch and the mode select switch ON to enable the fan to run at the certified airflow rate.

• For spot ventilation followed by continuous ventilation, increase the “TIME” setting of the user-adjustable time delay.

• For continuous ventilation, increase the “CFM” setting of the user-adjustable airflow rate
