WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING:
- Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.
- 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.
- 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.
- 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.
- When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
- Ducted fans must always be vented to the outdoors.
- Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) – protected branch circuit (ceiling installation only).
- This unit must be grounded.
- Not for Use in Kitchens.
- To reduce risk of fire and to properly exhaust air, be sure to duct air outside – Do not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces, or garages.
- WARNING: To Reduce The Risk Of Fire Or Electric Shock, Do Not Use This Fan With Any Solid-State Speed Control Device.
- The fan must not be installed in a ceiling thermally insulated to a value greater than R40.
CAUTION
- For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
- This product is designed for installation in ceilings up to a 12/12 pitch (45 degree angle). Duct connector must point up.
- To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.
- Please read specification label on product for further information and requirements.
CLEANING & MAINTENANCE
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.
PLAN THE INSTALLATION
ASSEMBLY INSTRUCTIONS
-
Before installation, you need to know:
When installing contractor packs, make sure to install any optional modules such as speed controls or humidity sensors with the fan housing to ensure wiring is completed properly. Module and grille plugs come packaged with the optional accessory and must be installed with the fan housing. -
Ceiling installation
-
Mount with mounting holes
Hold housing in place so that the housing contacts the bottom of the joist. Screw housing to joist through the hole A and hole B.
-
Mount with hanger bar
Slide one hanger bar into the channel on the housing and adjust as needed to fit between framing. Hold housing in place so that the housing contacts the bottom of the joist. Screw housing to joist through the hole A and hole B. Screw the hanger bar onto the other side of joist through its hole. Screw hanger bar to housing with screw A. -
Mount to I-joist
Side housing in into ho that the ousing contacts the dust of listed to fit joist. housing to joist through the hole A and hole B. Screw the hanger bar onto the joist through its hole. Screw hanger bar to housing with screw A .
-
Wall installation
-
When the product is installed on the wall, the adaptor shall be faced upward.
-
Slide hanger bar into the channel on the housing. Hold housing in place so that the housing contacts the bottom of stud. Screw housing to stud through the hole A and hole B on the same side. Screw the hanger bar onto the opposite stud through its hole. Screw hanger bar to housing with screw A. The minimum installation distance between studs is 13 3/8 in. (340mm.)
-
Install round ductwork
Connect the 4 in. round flexible ductwork (not included) to the damper/duct connector, and run the ductwork to a roof or wall cap (not included). Using metal foil tape (not included), secure all the ductwork connections so that they are air tight. The ducting from this fan to the outside of building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow.
CONNECT ELECTRICAL WIRING
Run 120V AC house wiring to the location of the fan. Use only UL-approved
connectors and UL-approved wire strain relief (not included) to attach the
house wiring to the wiring plate. Refer to the wiring diagram, and connect the
wires as shown.
OPERATION
See “Connect Wiring” for details.
The control box, located inside the fan housing, has three separate
adjustments:
- The low airflow knob adjusts the continuous run lower airflow from 30 CFM up to the air flow rate of the high fan speed determined by the toggle switch setting. The low speed is de-activated when set between OFF-30 CFM (factory set to OFF).
- The humidity sensor knob set user-adjustable setpoint. The humidity sensor is de-activated when set between OFF-30% (factory set to 80% (Ambient temperature of 77°F)). The time delay is factory set to 20 minutes and will switch the fan to the low speed setting after the Boost Switch is turned off for the set period of time.
- The toggle switch will adjust the upper fan speed setting from 50 to 100 CFM. (factory set to 100CFM).
To Turn Fan ON
Turn the Control Switch (according to the following “CONNECT ELECTRICAL
WIRING” ) ON.
- Fan will run at the certified high airflow rate if the Boost Switch is ON.
- Fan will run at the continuous run low airflow rate if the Boost Switch is OFF.
To Use Fan Time Delay Airflow Rate Change
- Turn the Control Switch ON.
- Turn the Ronct Switch ON . fan will run at the cortified hich airflow rate .
- When the Boost Switch is turned OFF, fan will continue to run at the certified high airflow rate until the time delay has elapsed (the delay time is 20 minutes), and then will automatically change to the continuous run low airflow rate.
To Turn Fan OFF
Turn the Control Switch OFF.
Fan run continuously at a low speed (adjustable by low airflow knob) and automatically boost up to high speed when either of these conditions is detected: a) Humidity above a user-adjustable setpoint (30%-80% relative humidity). b) rapid increases in humidity. After delay timer (20 minutes) returns fan to the default low speed. Humidity sensor description according to “HUMIDITY SENSOR OPERATION” and “SENSITIVITY ADJUSTMENT..
HUMIDITY SENSOR OPERATION
The humidity-sensing fan uses a sophisticated humidity sensor that responds
to: (a) rapid increases in humidity or (b) humidity above a user-adjustable
set-point (30%-80% relative humidity). Fan run continuously at a pre-set lower
level (set by Low airflow knob) and automatically boost up to certified
airflow rate when environmental conditions change. If the fan continuously
responds to changing environmental conditions, “H” (means “humidity”)
adjustment may be required.
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 minimum, “H” may be required.
To adjust the “H”:
- Disconnect power at service entrance.
- Through the grille, locate the slot marked “H.
- Carefully rotate the “H” adjustment toward maximum or minimum.
- Turn on power and check operation by turning on the shower or other humidity source until the fan turns on.
- Repeat above steps if necessary. When the temperature changes, humidity sensor values will have deviation.

Then, cut around inside the fan housing.
To attach the grille assembly to the fan housing, pinch the grille springs on the sides of the grille assembly, and position the grille into the housing with the grille springs in the appropriate slots. Push the grille assembly towards the ceiling to secure.
