• Use only special-purpose or dedicated parts if provided.
• Wear gloves to protect hands during installation.
• Do not install in locations where interior room temperature exceeds 40 °C (104 °F).
• For general ventilating use only. Do not exhaust hazardous or explosive materials and vapors.
• Do not install the fan above or inside a 45-degree angle projected outwards from the cooking equipment closest to the fan. (See Fig. A)
• Do not kink the supply wiring.
• Provide make-up air for proper ventilation.
• Do not connect multiple units in parallel; they may not function correctly.
• Avoid installing the unit where ducts are configured with excessive bending, successive bending, squeezed ducts, or bends close to the duct adaptor.

Description

This Panasonic product is listed by UL under file No. E78414.

It features a sirocco fan driven by a DC motor powered by an integral transformer. The DC motor is designed for long operating life, high dynamic response, higher speed ranges, and energy savings. The fan body is covered by a grille that attaches and detaches quickly via springs. A damper is included to prevent air counter-flow. The blower utilizes a high-capacity sirocco fan engineered to reduce noise levels.

Features

These products employ innovative, state-of-the-art technologies offering customizable features to improve indoor air quality. The DC motor technology makes these products 30% to 70% more energy efficient than minimum ENERGY STAR requirements, providing outstanding energy savings.

Unpacking and Supplied Accessories

Carefully unpack the unit from its carton. Verify all parts are present against the Supplied Accessories list.

Supplied Accessories

• Grille (1)
• Long screw (ST4.2X30) (5, including 1 spare)
• Installation instructions/Warranty sheet (1)

Wiring Diagram

The wiring diagram shows connections for AC 120 V 60 Hz power supply. It illustrates the connection of Live, Neutral, and Earth ground wires from the power supply (via a switch box and conduit) to the fan's components, including the junction box, PCB box, and motor. Wire nuts are used for connections.

Key wire connections:

• Power Supply: AC 120 V 60 Hz
• Live (Power Supply) connects to Live (Fan)
• Neutral (Power Supply) connects to Neutral (Fan)
• Earth ground (Power Supply) connects to Earth ground (Fan)

Dimensions

Dimensions are provided in inches (mm):

• Overall width/depth: 10 1/2 inches (266 mm)
• Ceiling hole size: 10 1/4 inches (260 mm)
• Depth from ceiling: 5 1/2 inches (140 mm)
• Duct connection diameter: 4 inches
• Other dimensions include: 12 (300), 3 3/8 (85), 3 3/4 (94), 1 1/2 (38), 3 (78), 13 (330), 5 (126) inches.

Installation I (Joist Mounting)

Step 1: Before installation, remove the protective tape from the damper and accessory screws from the adaptor. Ensure the damper opens and closes smoothly.

Step 2: Open one knock-out hole on the junction box. Choose the hole convenient for wiring.

Step 3: Remove the junction box cover and secure the conduit or stress relief to the opened knock-out hole.

Step 4: Connect wires according to the wiring diagram (Page 4). Follow local electrical safety codes and the National Electrical Code (NEC). Use UL-approved wire nuts to connect house power wires to the fan wires.

Step 5: Carefully mount the junction box cover, ensuring lead wires are not pinched.

Step 6: Finish ceiling work. The ceiling hole should be aligned with the inside edge of the flange. After finishing, fill the gap between the flange and the ceiling with caulk or sealant to prevent air leakage.

Step 7: Install the circular exhaust duct. A 4-inch circular duct is recommended. Squeeze the duct to fit the adaptor, slide it onto the adaptor, and secure it with clamps or ties. Seal the connection with mastic or approved foil tape. Note: If using a 3-inch round duct, a Panasonic 4" Oval - 3" Round reducer is required.

Step 8: Fix the flange of the frame to the joist using two long screws (ST4.2X30). Fix the suspension bracket to the joist using two long screws (ST4.2X30). Ensure the adaptor is installed upward. Do not replace the screws for the suspension bracket, as this could damage the cord in the PCB box and cause a fire.

Step 9: Install the grille. Insert the mounting springs into the slots on the fan body to attach the grille.

Installation II (Wall Mounting)

Step 1: Refer to Step 1 of Installation I.

Step 2: Fix the flange of the frame to the stud using two long screws (ST4.2X30). Fix the suspension bracket to the stud using two long screws (ST4.2X30). The adaptor must be installed upward. Do not replace the screws for the suspension bracket, as this could damage the cord in the PCB box and cause a fire.

Step 3: Complete the wiring and duct work, referring to Steps 2 and 3 of Installation I.

Step 4: Finish wall work. The wall hole should be aligned with the inside edge of the flange. After finishing, fill the gap between the flange and the wall with caulk or sealant to prevent air leakage.

Step 5: Install the grille, referring to Steps 4 and 5 of Installation I.

Maintenance (Cleaning)

Routine maintenance should be performed annually. Always disconnect power supply before working on the unit and wear gloves.

Maintenance Precautions

• Do not immerse the motor in water.
• Do not soak resin parts in water over 140 °F (60 °C).
• Never use gasoline, benzene, thinner, or other harsh chemicals for cleaning.

Cleaning Steps

• Remove Grille: Squeeze the mounting springs and carefully pull the grille down.
• Clean Grille: Clean the grille with a non-abrasive kitchen detergent. Do not use hot water. Wipe dry with a clean cloth. Ensure the grille is completely dry after cleaning.
• Clean Fan Body: Remove dust and dirt from the fan body using a vacuum cleaner. Then, use a cloth dampened with kitchen detergent to remove any remaining dirt. Wipe dry with a clean cloth.
• Reinstall Grille: Reinstall the grille after finishing cleaning.

Practical Guide to Installation

Ducting Recommendations:

• Ducting significantly impacts airflow, noise, and energy use. Use the shortest, straightest duct routing possible for best performance. Avoid using ducts smaller than recommended.
• Insulation around ducts can reduce energy loss and inhibit mold growth.
• Fans installed with existing ducts may not achieve rated airflow.
• A circular 4-inch duct is recommended for optimal performance and installation.
• Ensure duct joints and exterior penetrations are sealed with caulk or similar material to create an air-tight path, minimize building heat loss/gain, and reduce condensation potential.
• Place or wrap insulation around the duct and/or fan to minimize condensation buildup and reduce heat loss/gain.

Recommended Ducting Components:

• 4-inch roof jack, wall cap, or soffit vent with a back-draft damper.
• A 2-3 ft straight run before any elbow.
• A short piece of flexible duct can aid alignment and absorb sound.
• Foil tape should tightly cover all metal duct joints.
• Mechanically connect the duct to the termination and seal with mastic or approved foil-faced tape.
• For attic installations, caulk the box to the drywall.
