WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. Usethisunitonlyin themannerintendedby themanufacturer.
Ifyouhavequestions,contactthemanufacturerattheaddress
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
publishedby the NationalFire ProtectionAssociation (NFPA),
and the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and the local code au-
thorities.
5. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
WARNING
6. Ducted fans must always be vented to the outdoors.
7. If this unit is to be installed over a tub or shower, it must be
marked as appropriate for the application and be connected
toaGFCI(GroundFaultCircuit Interrupter) -protectedbranch
circuit.
8. Never place a switch where it can be reached from a tub or
shower.
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 ceiling installation only.DO NOT
MOUNT THIS PRODUCT IN A WALL.

PLAN THE INSTALLATION
The location of your
ULTRA-SENSAIRE®fan is
very important. Follow
these guidelines for best
operation:
• TheULTRA-SENSAIRE®
fan uses a humidity
sensor that responds to
bothincreasesinhumidity
and to humidity levels.
Thehumiditysensor may
turn the fan ON when
environmental
conditions change. If the
fan continuously
responds to changing environmental conditions, "SENSITIVITY"
adjustment may be required.
• Locate unit above (GFCI protected circuit required) or within 5 feet of
shower head.
• Locate unit away from heating or cooling sources which can affect
humidity levels.
• Do not locate near window. Unit may respond to the outdoor humidity
level.
• Unit must be installed in ceiling to properly sense moisture.
• Locate unit only on flat ceilings up to 12 feet high for proper sensing.
• The fan will operate most efficiently when located where the shortest
possible duct run and minimum number of elbows will be needed.

1. Squeeze grille springs
together and insert
springs into slots in
blower assembly.
2. Push grille up against
ceiling.
3. Turnonpowerandcheck
fan operation.
SENSOR OPERATION
The ULTRA-SENSAIRE® fan uses a sophisticated humidity sen-
sor that responds to: (a) rapid to moderate (user-adjustable)
increases in humidity or (b) humidity above a user-adjustable
set-point (50%-100% Relative Humidity). The humidity sensor
may occasionally turn the fan ON when environmental condi-
tions change. If the fan continuously responds to changing
environmental conditions, "SENSITIVITY" adjustment may be
required.
MANUAL ON WITH TIMED OFF
The ULTRA-SENSAIRE®fan has an additional operation fea-
ture. For odor or vapor control, the fan can be energized by
cycling the power switch. Once the fan has been energized in
this manner, it will remain on for the user-adjustable "TIMER"
period (approx. 5 to 60 minutes). This period is factory-set for
approximately 20 minutes.
To manually energize the fan:
1. If fan power switch is already ON, proceed to Step 2; other-
wise, turn power switch ON for more than 1 second.
2. Turn fan power switch OFF for less than 1 second.
3. Turn fan power switch back ON and fan will turn ON.
USE AND CARE
SENSITIVITY ADJUSTMENT
The "SENSITIVITY" has been factory set for most shower appli-
cations. However, if the fan is in a tub area or is being used for
dampnesscontrol, the"SENSITIVITY" may need to beincreased
toward maximum ("MAX."). If the control is responding too of-
ten to changing environmental conditions, movement toward
less ("MIN.") "SENSITIVITY" may be required.
To adjust the "SENSITIVITY":
1. Disconnect power at service entrance.
2. Through the grille, locate the screwdriver slot marked "SEN-
SITIVITY".
3. Using a small, flat-blade screwdriver, carefully rotate the
"SENSITIVITY" adjustment toward "MAX." or "MIN."
4. Turnon power and check operation by turning on the shower
or other humidity source until the fan turns on.
5. Repeat above steps if necessary.
TIMER ADJUSTMENT
The ULTRA-SENSAIRE®fan has a "TIMER" that can be ad-
justed from 5 to 60 minutes (factory-set at approx. 20 minutes).
This "TIMER" controls the length of time that the fan remains
ON (a) after the sensor has stopped sensing a rise in humidity
and the humidity level is below the user-adjustable set-point or
(b) after being energized by cycling the power switch.
To adjust the "TIMER":
1. Disconnect power at service entrance.
2. Through the grille, locate the screwdriver slot marked
"TIMER".
3. Using a small, flat-blade screwdriver, carefully rotate the
"TIMER" adjustment to desired setting (from 5 to 60 min-
utes).
4. Check operation by cycling the power switch as instructed
under "MANUAL ON WITH TIMED OFF" or by turning on a
humidity source until the fan turns on.
5. Turn humidity source off and time the unit.
6. Repeat above steps if necessary.
WARNING
BEFORE CLEANING, SERVICING OR ADJUSTING THE
UNIT, SWITCH POWER OFF AT SERVICE PANEL. LOCK
SERVICE PANEL TO PREVENT POWER FROM BEING
SWITCHED ON ACCIDENTALLY.

SENSOR CLEANING
The humidity sensor is mounted behind the grille. The sensor
will operate most reliably when cleaned occasionally as fol-
lows:
1. Disconnect power at service entrance.
2. Remove the grille. Use a dry dustcloth or lightly vacuum to
clean sensor and grille. DO NOT USE ABRASIVE CLOTH,
STEEL WOOLPADS, OR SCOURING POWDERS.
3. DO NOT USE cleaning sprays, solvents, or water on or near
the sensor!
