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 ser-

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 combus-

tion and exhausting of gases through the

flue (chimney) of fuel burning equipment to

prevent backdrafting. Follow the heating equip-

ment manufacturer’s guideline and safety

standards such as those published by the

National Fire Protection Association (NFPA),

and the American Society for Heating, Re-

frigeration 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. Acceptable for use over a tub or shower when

connected to a GFCI (Ground Fault Circuit

Interrupter) - protected branch circuit.

8. This unit must be grounded.

CLEANING &

MAINTENANCE

Installer: Leave this manual

with the homeowner.

For quiet and efficient operation, long life,

and attractive appearance - lower or remove

grille and vacuum interior of unit with a dust-

ing brush attachment.

The motor is permanently lubricated and

never needs oiling. If the motor bearings

are making excessive or unusual noises,

replace the motor/blower wheel assembly.

SENSOR CLEANING

The humidity sensor is mounted in the grille.

The sensor will operate most reliably when

cleaned occasionally as follows:

1. Disconnect power at service entrance.

2. Remove the grille. 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!

OPERATION

The humidity control and fan can be op-

erated separately. Do not use a dimmer

switch to operate the humidity control or

light. See “Connect Wiring” for details.

SENSOR OPERATION

This humidity-sensing

fan responds to: (a)

rapid to moderate humidity increases and

(b) humidity above a 50%-80% relative

humidity (RH) set-point. (a) and (b) are

set with “HUMIDITY” adjustment. Fan may

occasionally turn on when environmental

conditions change. If the fan continuously

responds to changing environmental con-

ditions, “HUMIDITY” 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 grille

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 “MINUTES” 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.

HUMIDITY ADJUSTMENT

“HUMIDITY” has been factory set for most

shower applications. If the fan is in a tub

area or is used for dampness control, the

“HUMIDITY” may need to be decreased

toward 50% RH. If the control is responding

too often to changing environmental condi-

tions, adjustment toward 80% RH may be

required. To adjust the “HUMIDITY”:

1. Turn power off at electrical service

panel.

2. Through the grille, locate the “HUMIDITY”

screwdriver slot.

3. Using a small, flat-blade screwdriver,

carefully rotate “HUMIDITY” adjustment

toward 50 or 80.

4. Turn power on and check operation by

turning on shower or other humidity

source until fan turns on.

5. 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 after (a) rise

in humidity and (b) humidity level are both

below the user-adjustable “HUMIDITY”

setting or after being energized by cycling

power switch.

To adjust the timer:

1. Disconnect power at electrical service

panel.

2. Through the grille, locate the “MINUTES”

screwdriver slot.

3. Using a small, flat-blade screwdriver,

carefully rotate “MINUTES” adjustment

to desired setting (5 to 60 minutes).

4. 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.

5. Check timer setting with watch or clock

after turning humidity source off if it was

turned on in Step 4.

6. Repeat above steps if necessary.
