SECTION A Safety Information

Please read all instructions before installation and use.

1. Ensure the power supply is 110-120V, 60Hz.
2. Do not install in areas where temperatures exceed 104°F (40°C).
3. Do not bend or damage the power cord.
4. Follow all local building and electrical codes, including NEC and OSHA regulations.
5. Disconnect power at the circuit breaker before servicing.
6. Protect all wiring from sharp edges, oil, grease, and heat sources.
7. Do not install where airflow is restricted.
8. Ensure adequate air intake for proper ventilation.
9. Approved for installation above a shower or bathtub when connected to a GFCI-protected circuit. The control switch must be located out of reach.
10. Do not use to ventilate hazardous or explosive materials.
11. Do not operate the fan with solid-state speed controls.
12. This unit is double insulated and does not require grounding.
13. Do not install in cooking areas (see Fig. A).

Fig. A Description: A diagram illustrating a cooking area. It shows cooking equipment on a floor and indicates a zone labeled "Cooking area" with a dashed outline, stating "Do not install above or inside this area".

14. Exhaust air must be vented outdoors not into wall cavities, ceilings, attics, or garages.
15. Install the fan at least 7 feet (2.1 meters) above the floor.

WARNING: To reduce the risk of fire or electric shock, follow all safety precautions and do not install the fan in prohibited zones.

16. Use only as intended by the manufacturer. Contact customer service with questions.
17. Installation must be performed by a qualified professional, following all local safety codes and fire-rated construction rules.
18. Ensure proper airflow and venting for gas-burning appliances to prevent backdrafting. Follow NFPA and ASHRAE guidelines.
19. Do not install in ceilings with insulation values greater than R40.
20. Avoid damaging hidden utilities or wiring during installation.
21. Always lock or tag the power source before servicing. If locking is not possible, use a warning tag to indicate that the power should not be turned on.
22. For over-shower or bathtub installation, ensure the product is rated for that use and installed at least 1 meter (3.3 ft) from the water source (see Fig. B). The fan should be installed on the opposite side of the tub on the ceiling. It is acceptable for use over a bathtub or shower when connected to a GFCI-protected branch circuit (refer to Fig. B).

Fig. B Description: A diagram showing a bathtub with a shower. An arrow indicates the fan's placement above the tub, with a label ">1.0M" signifying a minimum distance from the water source.

23. Do not connect to rigid metal conduit; use flexible conduit only.
24. Keep ductwork straight and minimize bends.
25. Ductwork size must be a minimum of the discharge and should not be reduced.

PLANNING INSTALLATION

Before starting the installation, ensure that all parts are present. Compare the parts with the package contents list and hardware list. If any part is missing or damaged, do not proceed with the installation.

WARNING: Turn off the power at the breaker box before beginning installation.

NOTE: Wiring configuration may vary depending on your previous fan setup. Some components needed for installation may not be included. Additional supplies can be found at your local hardware store.

SECTION D Installation-Template

Diagram Descriptions:

• Diagram 2: Shows the "Wood Frame" fixed onto the ceiling.
• Diagram 3: Illustrates the "Housing" and "Outer Frame" components of the fan.
• Diagram 4: Shows the power cord connecting to a "Socket" and a "Power Switch".
• Diagram 5: Depicts screwing the fan base into the wood frame. Angle brackets can be added for extra support if needed.
• Diagram 6: Shows how to squeeze "spring clips" on the grille and align them with the mounting slots to securely install and fasten the panel in place.

SECTION E Installation-Operating Instructions

1. Mark the Ceiling: Draw a square measuring 11.6" x 11.6" on the ceiling where you plan to install the fan.
2. Cut the Square Opening: Use the appropriate tools to carefully cut out the square you marked in step 1.
3. Prepare Wooden Support Boards: Take two wooden boards, each measuring 3" wide, 1" thick, and 14" long. The boards should be sturdy. Place them inside the square opening, projecting approximately 0.9" from the ceiling. Secure the boards firmly to the ceiling using nails or screws.
4. Set Up Ventilation Duct and Power Cord: Before proceeding, prepare the ventilation duct and power cord. Connect the ventilation duct to the fan's outlet, and connect the power cord from the fan to the control switch. The control switch will allow you to operate the fan. Refer to the wiring diagram in Chapter 2 for guidance. If you are not familiar with electrical work, please hire a licensed electrician to handle the wiring.
5. Install the Fan: Once the duct and wiring are connected, carefully insert the fan into the square opening. Use screws to secure the fan in place, following the direction indicated by the arrow in the provided image.
6. Attach the Panel: Grip the spring clips on both sides of the panel and align them with the installation holes on the fan unit. Once aligned, firmly secure and fasten the panel into place.
7. Installation Complete: Congratulations! Your exhaust fan installation is now complete.

SECTION F Ventilation Fan Operation

1. Turning the Fan On: Flip the wall switch to the ON position to activate the fan.
2. Turning the Fan Off: Flip the wall switch to the OFF position to deactivate the fan.

Humidity Sensor Operation (Model VH1797):

NOTE: The product's humidity sensor cannot be manually adjusted. The fan automatically adjusts its airflow based on the surrounding humidity levels.

SECTION G Troubleshooting

NOTE: Holding a tissue near the fan is not a reliable test. If the fan clears steam within ~15 minutes after a shower, it is functioning properly.

SECTION H Cautions

1. Read all instructions and safety warnings before beginning installation. Review the exploded view diagram provided.
2. Disconnect power at the circuit breaker or by removing the fuse before performing any electrical work. This ensures full disconnection from the power supply.

7. Use a power cord rated for at least 10 amps.
8. Do not cut or notch joists, beams, or rafters to install the fan.
9. Be careful not to damage hidden electrical wiring or plumbing when cutting into the ceiling.
10. Install the fan so that switches and controls are out of reach of anyone using a bath or shower.
11. Do not install the fan directly above a shower or bathtub, or in any location where it could be splashed with water.
12. After installation, verify that all connections are secure to prevent the unit from falling and causing injury or property damage.
13. Do not insert objects through the fascia grille.
14. If the power cord is damaged, it must be replaced by the manufacturer, their service agent, or a qualified electrician using only manufacturer-approved parts.
15. Do not install or use the fan outdoors or in any area where it could be exposed to water or moisture. Indoor use only.
16. The fan should be mounted at least 2.3 meters (7.5 feet) above the floor.
17. A multi-pole switch is required for installation. The gap between contacts must be at least 3 mm.
18. Use vent covers to prevent the entry of water or insects into the ducting system.

SECTION I Maintenance

1. Turn off the power before performing any maintenance.
2. Remove the louver, cover, and fan blade. Clean these parts with water and a brush. Use a soft cloth and a mild detergent to wipe off grease. Do not use water over 60°C (140°F), petroleum-based products, benzene, thinner, or any other harsh solvents. Important: Do not allow water to enter the motor.
3. Dry all cleaned parts thoroughly using a soft dry cloth or allow them to air dry completely. Reassemble all parts in the reverse order of removal.
4. During the warranty period, if the fan malfunctions due to manufacturing defects under normal use, it will be repaired or replaced free of charge.
