5. Use embossed measuring guides on side of housing to position

housing for proper wall or ceiling thickness. MAKE SURE HOUS-

ING WILL BE FLUSH WITH FINISHED CEILING OR WALL. Nail

housing or stude joist using four nails to ensure a solid, quiet

installaltion.

3. Turn off electrical power at service entrance and connect

power cable to housing using appropriate connector. Wire black

to black, white to white. Insert ground wire into grounding clip and

secure to emboss in housing. Push all wiring up into corner of unit

and replace wiring cover. Make sure cover holds housing flap in

place against side or top of housing. CAUTION: DO NOT ALLOW

WIRES TO EXTEND OUTSIDE OF WIRING BOX. Wire left

exposed will become pinched or cut when motor plate is

installed. Electrical shock may result.

4. Choose the location for your fan. For best performance, use the

shortest possible duct run and a minimum number of elbows. For

wall installations: Position unit so damper flap closes when unit is

INSTALL THE HOUSING

1. Choose the location for your fan in the ceiling. For best possible

performance, use the shortest possible duct run and a minimum

number of elbows.

2. Position mounting brackets against joist so that bottom

edge of housing will be flush with finished ceiling.

Additional positioning feature for 5/8”, 1”, & 1-1/4”

thick ceiling material:

Holes in corners of housing are labeled with various

ceiling material thicknesses. Position housing so bottom

edge of joist is visible through a matched set of holes.

The housing is now in the proper position for that ceiling

material thickness.

Additional positioning feature for 1/2” thick ceiling

material:

Bend two tabs, on side of housing, 900outward. Lift

housing until tabs contact underside of joist.

Mark the keyhole slot on both mounting brackets.

3. Set housing aside and drive nails partially into joist at the top of

both keyhole marks.

4. Hang housing from nails and pound nails tight. To ensure a noise-

free mount, pound another nail through the top hole of each

mounting tab.

WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR IN-

JURY 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 quali-

fied person(s) in accordance with all applicable codes and stan-

dards, 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 Con-

ditioning Engineers (ASHRAE), and the local code authorities.

5. When cutting or drilling into wall or ceiling, do not damage elec-

trical wiring and other hidden utilities.

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

7. To reduce the risk of fire, use only metal ductwork.

8. If this unit is to be installed over a tub or shower, it must be

marked as appropriate for the application and be connected to a

GFCI (Ground Fault Interrupter) - protected branch circuit.

9. Never place a switch where it can be reached from a tub or

shower.

10. This unit must be grounded.

CAUTION

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

ous or explosive materials and vapors.

2. To avoid motor bearing damage and noisy and/or unbalanced

impellers, keep drywall spray, construction dust, etc. off power

unit.

3. Please read specification label on product for further informa-

tion and requirements.

To clean grille: Use appropriate vacuum attachment or remove

grille and clean with a soft cloth and mild soap or detergent. Dry

grille thoroughly before reinstalling.

To clean blower assembly: Remove grille, unplug blower from

housing, remove blower mounting nuts, and carefully remove blower

from housing. Use appropriate vacuum attachment or a soft cloth

and mild soap or detergent to clean blower discharge area and

wheel. DO NOT ALLOW WATER TO ENTER MOTOR. Make sure

blower assembly is completely dry before reinstalling.

Motor is permanently lubricated. Do not oil or disassemble motor.

USE AND CARE

Ventilator is designed for continuous operation. If desired, it may be

controlled using an on/off switch or a solid-state, variable speed

control. Follow wiring instructions packed with control, and adhere

to all local and state codes, and the National Electrical Code.
