HUMIDITY SENSING RECESSED

FLUORESCENT FAN / LIGHT

READ AND SAVE THESE INSTRUCTIONS

CLEANING &

MAINTENANCE

Installer: Leave this manual

with the homeowner.

To clean trim ring / baffle: Vacuum with a

soft brush attachment or remove trim ring /

baffle and clean with a soft cloth.

SENSOR CLEANING

The humidity sensor is mounted in the trim

ring/baffle. The sensor will operate most

reliably when cleaned occasionally as follows:

1. Disconnect power at service entrance.

2. Remove the trim ring/baffle. Use a dry

dustcloth, clean toothbrush, or lightly

vacuum to clean sensor and grille.

DO NOT USE ABRASIVE CLOTH,

STEEL WOOL PADS, OR SCOURING

POWDERS.

3. DO NOT USE cleaning sprays, solvents,

or water on or near the sensor!

To clean inside of housing: Remove trim

ring / baffle and vacuum inside of housing

with a soft brush attachment.

Motor is permanently lubricated. Do not oil or

disassemble motor.

See “Service Parts” section for a list and

illustrations of service parts.

OPERATION

The light, fan and humidity control can be operated

together or independently using multi-function switch

wall controls.

• Use a 3-function control to independently operate

light, fan and humidity control.

• Use a 2-function control to independently operate

light and humidity control. For fan operation see

MANUAL ON WITH TIMED OFF section below.

• Use a 2-function control to independently operate

light and fan. Wire humidity control direct to insure

humidity control is always on.

See “Connect Wiring” section for various wiring

options.

Do not use a dimmer switch control to operate

light, fan or humidity control.

SENSOR OPERATION

This humidity-sensing

fan responds to: (a) rapid to

moderate humidity increases and (b) humidity above

a 50%-100% relative humidity set-point. (a) and (b)

are set with “SENSITIVITY” adjustment. Fan may

occasionally turn on when environmental conditions

change. If the fan continuously responds to changing

environmental conditions, “SENSITIVITY” adjustment

may be required (see section below).

STATUS INDICATOR

This indicator can only be seen by looking directly at

it. Normal mode is 5-seconds on and off. If it blinks

rapidly for 5-seconds and then off, check sensor

connections on trim ring/baffle and fan housing.

MANUAL ON WITH TIMED OFF

For odor or vapor control, the fan can be energized

by cycling its wall-mounted switch if one is installed.

Once the fan has been turned on in this manner, it

will remain on for the set “TIMER” period.

To manually energize the fan:

1. Go to Step 2 if switch is already on; otherwise,

turn switch on for more than 1 second.

2. Switch off for less than 1 second.

3. Switch back on and fan will turn on.

SENSITIVITY ADJUSTMENT

“SENSITIVITY” has been factory set for most

shower applications. If the fan is in a tub area or is

used for dampness control, the “SENSITIVITY” may

need to be increased toward maximum (“MAX.”).

If the control is responding too often to changing

environmental conditions, adjustment toward less

(“MIN.”) “SENSITIVITY” may be required. To adjust

the “SENSITIVITY”:

1. Turn power off at electrical service panel.

2. Remove bulb.

3. Through trim ring/baffle, locate the “SENSITIVITY”

screwdriver slot.

4. Using a small, flat-blade screwdriver, carefully

rotate “SENSITIVITY” adjustment clockwise

toward “MAX.” or counterclockwise toward “MIN.”

5. Re-install bulb.

6. Turn power on and check operation by turning

on shower or other humidity source until fan

turns on.

7. Repeat above steps if necessary.

TIMER ADJUSTMENT

This humidity-sensing fan has a “TIMER”. It is user-

adjustable from 5 to 60 minutes and is factory-set

at 20 minutes. The “TIMER” controls how long the

fan remains on (a) after rise in humidity and (b)

humidity level are both below the user-adjustable

“SENSITIVITY” setting or after being energized by

cycling power switch.

To adjust the “TIMER”:

1. Disconnect power at electrical service panel.

2. Remove bulb.

3. Through the trim ring/baffle, locate the

“TIMER” screwdriver slot.

4. Using a small, flat-blade screwdriver, carefully

rotate “TIMER” adjustment clockwise

to increase time or counterclockwise to

decrease time.

5. Re-install bulb.

6. Turn power on and check operation by cycling

power switch as instructed under “MANUAL

ON WITH TIMED OFF” or by turning on a

humidity source until fan turns on.

7. Check “TIMER” setting with watch or clock

after turning humidity source off if it was

turned on it Step 6.

8. Repeat above steps if necessary.

CAUTION

1. For general ventilating use only. Do not use

to exhaust hazardous or explosive materials

and vapors.

2. To avoid motor bearing damage and noisy and/

or unbalanced impellers, use the cardboard

protector (provided) to keep drywall spray,

construction dust, etc. off power unit.

3. The fluorescent bulb used with this product

inserts straight into the bulb socket. Do not

attempt to insert or remove bulb by twisting it.

4. Please read specification label on product for

further information and requirements.

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. Never place a switch where it can be reached from

a tub or shower.

8. Do not use a dimmer switch to operate the light in

this unit.

9. Install this unit in a flat ceiling only.

10. For use in non fire rated installations only.

11. Not for use in environmental air handling spaces.

12. 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 Circuit

Interrupter) - protected branch circuit.

13. Do not install in a ceiling thermally insulated to a

value greater than R40.

14. This unit must be grounded.
