WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer at the address or telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

3. Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction codes and standards.

4. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.

6. Ducted fans must always be vented to the outdoors.

7. Use only ON/OFF switch, mechanical timer or relay-switched control.

8. Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit.

9. This unit must be grounded.

CAUTION

1. For general ventilating use only. Do not use to exhaust

hazardous or explosive materials and vapors.

2. This product is designed for installation in flat ceilings. Sensor will not function reliably if product is not installed in flat ceiling. DO NOT MOUNT THIS PRODUCT IN A WALL.

3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.

4. Please read specification label on product for further information and requirements.

NOT FOR USE IN A COOKING AREA

Do not install above or inside this area

Typical Installation

• Installation is the same for:

Joists I-Joists Trusses

• Fits in 2" x 8" ceiling construction.

• Infinitely adjust the fan position between joists from 14" to 24" on center.

The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straighest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow.

6-inch round rigid metal duct is recommended for best performance.

WARNING Before servicing or cleaning unit, switch

power off at service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten

a prominent warning device, such as a tag, to the service panel.

Operation

It is normal for this ventilation fan to take approximately 5 seconds to start running after it is turned on.

Modes

(For reference, wiring diagrams are on pages 5 and 10.)

Continuous ventilation:

1. Turn master wall switch on.

2. Fan operates at user-adjustable airflow rate.

Motion sensing:

1. If master wall switch is not already on, turn it on.

2. Turn sensor/control wall switch on. Some installations may not have a separate sensor/control wall switch; where it is combined with master wall switch.

3. Fan operates at certified airflow rate and sensor detects motion.

4. When no more motion is detected, fan enters time delay mode. (See below.)

Manual-on (optional manual-on wall switch must be installed):

1. Turn master and manual-on wall switches on (sensor/control wall switch can be on or off).

2. Fan operates at certified airflow rate.

3. When manual-on wall switch is turned off, fan enters timed-off mode. (See below.)

Time Delay: Fan continues to run at cerified airflow rate until user-adjustable TIME

delay has passed, then fan reverts to user-adjustable airflow rate.

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

For quiet and efficient operation, long life and attractive appearance, remove Grille and vacuum interior of unit with a dusting brush attachment.

Do not use cleaning sprays, solvents or water on, or near, the sensor.

Motor is permanently lubricated and never needs oiling. If motor is making excessive or unusual noises, replace Control Assembly and Motor.

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 TIME adjustment until the arrow points to the desired minutes of time delay.

* 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.

ZB80M n ZB110M Installation Guide

Troubleshooting

Before continuing, turn off power as previously noted in WARNING and CAUTION sections at the top of the previous page.

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

• Check that Blower Wheel spins freely.

Symptom: Motion mode does not operate fan at certi-

fied air flow rate.

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

Symptom: Fan runs erratically.

• Check that Blower Wheel is firmly attached to Motor shaft and both spin freely.

Service Parts

Symptom: Fan seems noisy.

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

• Check that back draft damper in wall or roof cap pivots freely. Dampers are sometimes mistakenly painted shut or obstructed by bird or insect debris.

Symptom: Fan does not properly ventilate room.

• For spot ventilation, turn both master switch and sensor/ control wall switch ON, so sensor/control operates fan at certified airflow rate.

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

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