CAUTION
CLEANING & MAINTENANCE
OPERATION
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 switching 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 equip ment 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. Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch
circuit (ceiling installation only).
8. This unit must be grounded.
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 ceilings up to a 12/12 pitch (45 degree angle). Duct connector must point up.
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.
For quiet and efficient operation, long life, and attractive appearance - lower or remove grille and vacuum interior of unit
with the dusting brush attachment.
The motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace the motor with the exact service motor. The impeller should also be replaced.
Use an on/off switch to operate this fan. See “Connect Wiring” for details.
For model OD-5006HS OD-8011HS
The humidity control and fan can be operated separately. Use a 1 or 2 function wall control. Do not use a dimmer switch
to operate the humidity control or light. See “Connect Wiring” for details.
SENSOR OPERATION
The humidity-sensing fan uses a sophisticated humidity sensor 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 conditions change. If the fan continuously responds to changing environmental conditions, “H” (means “humidity”) adjustment may be required. This figure is factory-set for about 75%
(Ambient temperature of 25℃).
SENSITIVITY ADJUSTMENT
The “H” has been factory set for most shower applications. However, if the fan is in a tub area or is being used for dampness control, the “H” may need to be increased toward maximum “+”. If the control is responding too often to changing
environmental conditions, movement toward less “-” “H” may be required.
To adjust the “H”:
1. Disconnect power at service entrance.
2. Through the grille, locate the slot marked “H”.
3. Carefully rotate the “H” adjustment toward “+” or “-”.

TYPES OF TYPICAL INSTALLATIONS
1. Do not use in a cooking area.
2. Two ways to connect ductwork to a factory-shipped unit.
ASSEMBLY INSTRUCTIONS
1. Housing mounted to I-joists (Start at “ASSEMBLY INSTRUCTIONS 1”)
2. Housing mounted to joists (Start at “ASSEMBLY INSTRUCTIONS 1” )
3. Housing mounted to truss (Start at step “ASSEMBLY INSTRUCTIONS 2”)
2
1.MOUNT HOUSING TO JOIST OR I-JOIST.
Hold the housing so that it is in contact with the bottom of the joist.
Place the fan housing next to the ceiling joist. Using wood screws
attach the housing loosely to the ceiling joist through the keyholes
in the mounting tabs. Adjust the housing to be flush with th
finished ceiling. For the grille to fit properly, the housing’s rim must
not extend beyond the finished ceiling surface. When the housing
is correctly adjusted, tighten the screws in the slots.
4. Turn on power and check operation by turning on the shower or other humidity source until the fan turns on.
5. Repeat above steps if necessary.
When the temperature changes, humidity sensor values will have deviation.
TIMER ADJUSTMENT
The humidity sensing fan has a “T” (means timer) that can be adjusted from 5 to 60 minutes (factory-set at about 20 minutes). This “T” controls the length of time that the fan remains ON after the sensor has stopped sensing a rise in humidity
and the humidity level is below the user-adjustable set-point. To adjust the “T”:
1. Disconnect power at service entrance;
2. Through the grille, locate the slot marked “T”;
3. Carefully rotate the “T” adjustment to desired setting (from 5 to 60 minutes).
4. Check operation 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.

2. MOUNT WITH HANGER BARS
Insret the hanger bars into the slots in the housing. Place the fan
housing between the joists, make sure the bottom of the housing
is even with the finished ceiling. Extend the hanger hars to the
joist. Use screws to secure the hanger bars to the
ceiling joists.
DUCT
3. ATTACH DAMPER/DUCT CONNECTOR
Snap the damper/duct connector onto the fan housing. The
connector must be flush with the top of the housing, and the
damper flap should fall closed.
4. INSTALL ROUND DUCTWOTK
Connect the round ductwork (not included) to the damper/duct connector,
and run the ductwork to a roof or wall cap (not included). Using tape (not
included), secure all the ductwork connections so that they are air tight.
