WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a). Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.
b). 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.
c). 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.
d). 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.
e). When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
f). Ducted fans must always be vented to the outdoors.
g). Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) – protected branch circuit (ceiling installation only).
h). This unit must be grounded.
i). Not for Use in Kitchens.
j). 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
k). WARNING: To Reduce The Risk Of Fire Or Electric Shock, Do Not Use This Fan With Any Solid-State Speed Control Device.
l). The fan must not be installed in a ceiling thermally insulated to a value greater than R40.

CAUTION

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.

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.

OPERATION

See “CONNECT ELECTRICAL WIRING” for details.

Humidity Sensor for MODEL:SEP120H-EZ
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. See “CONNECT ELECTRICAL WIRING” for details.
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). 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 80% ( 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 “-”.
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.

Leave this manual with the homeowner.

PLAN THE INSTALLATION

1. Do not use in a cooking area.
2. Two ways to connect ductwork to a factory-shipped unit.

ASSEMBLY INSTRUCTIONS

Please remove duct assembly and blower assembly before installation.

A. NEW CONSTRUCTION INSTALLATION

A1. INSTALL EASY MOUNTING FRAME (Fig.1)

A2. INSTALL DUCT AND HOUSING (Fig.2 &3 ) Attach duct in frame and fix with screws.

Put the tab in the housing, push housing in frame and slide across slot in duct, secure frame, duct and housing with two screws. Then put the tab out of the housing.

A3. INSTALL BLOWER ASSEMBLY (Fig.4 &5)

Install blower assembly in housing and secure with screws.

A4. INSTALL JUNCTION BOX AND DUCTWORK(Fig.6)

Remove junction box cover and connect electrical wiring (refer to wiring diagram), replace the junction box cover. 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.

B. RETROFIT INSTALLATION

B1. INSTALL EASY MOUNTING FRAME (Fig.7)

Cut ceiling opening and remove the existing fan. Then Install easy mounting frame in place.

B2. INSTALL JUNCTION BOX AND DUCTWORK (Fig.8)

Follow the step A4 on page 3.

B3. INSTALL DUCT AND HOUSING (Fig.9)

Follow the step A2 on page 2.

B4. INSTALL BLOWER ASSEMBLY (Fig.10)

Follow the step A3 on page 2.

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 120 V AC house wiring to the location of the fan. Use only UL-approved connectors (not included) to attach the house wiring to the wiring plate. Refer to the wiring diagram, and connect the wires as shown.
