ACCORDANCE WITH NATIONAL AND LOCAL ELECTRICAL CODES.

IMPORTANT SAFETY INSTRUCTIONS

- PLEASE READ THIS SECTION CAREFULLY BEFORE INSTALLATION -

WARNING

1) Installation and electrical wiring must be done by qualified professionals and in accordance
with all applicable codes and standards, including fire-rated construction.

2) When cutting or drilling into wall or ceiling, be careful not to damage electrical wiring or
other hidden utilities.

3) Ducted fans must be vented to the outside.
a) Before servicing or cleaning unit, open the light panel and SWITCH POWER OFF AT

SERVICE PANEL.

b) Clean all grease laden surfaces frequently. To reduce the risk of fire and to disperse air

properly, make sure to vent air outside. DO NOT vent exhaust air into wall spaces,
attics, crawl spaces or garages.

NOTE - This warranty is invalid without an authorized agent’s receipt or if

:

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR PERSONAL
INJURY, OBSERVE THE FOLLOWING:

unit is damaged due to misuse, poor installation, improper use,
mistreatment, negligence or any other circumstances beyond the
control of KOBE RANGE HOODS authorized agents. Any repair
carried out without the supervision of KOBE RANGE HOODS
authorized agents will automatically void the warranty.

damages to personal property or real estate or any bodily injuries
whether caused directly or indirectly by the range hood.

WARNING

- Keep all fan, baffle/spacer/filter/oil tunnel/oil container and grease-laden surfaces clean.
Grease should not be allowed to accumulate on fan, baffle/spacer/filter/oil tunnel/oil
container.

- Always turn hood ON when cooking.

- Use high settings on cooking range ONLY when necessary.

- Do not leave cooking range unattended when cooking.

- Always use cookware and utensils appropriate for the type and amount of food prepared.

- Use this unit only in the manner intended by the manufacturer.

- Before servicing, switch power off at service panel and lock service panel (if possible) to
prevent power from switching on accidentally.

- Clean ventilating fan frequently.

: TO REDUCE THE RISK OF PERSONAL INJURY IN THE EVENT OF A

RANGE TOP GREASE FIRE:

What to Do In The Event Of a Range Top Grease Fire

- SMOTHER FLAMES with a tight fitting lid, cookie sheet, or metal tray, and then turn off the
burner. KEEP FLAMMABLE OR COMBUSTIBLE MATERIAL AWAY FROM FLAMES. If
the flames do not go out immediately, EVACUATE THE AREA AND CALL THE FIRE
DEPARTMENT or 911.

- NEVER PICK UP A BURNING PAN – You May Get Burned.

- DO NOT USE WATER, including wet dishcloths or towels – a violent steam blast will result.

- Use an extinguisher ONLY if:
a) You have a Class A, B, C extinguisher and know how to operate it.
b) The fire is small and contained in the area where it started.
c) The fire department has been called.
d) You can fight the fire with your back to an exit.

What to Do If You Smell Gas

-

Extinguish any open flame.

-

Do not try to turn on the lights or any type of appliance.

-

Open all doors and windows to disperse the gas. If you still smell gas, call the Gas
Company and Fire Department right away.

CAUTION

1) For general ventilation use only. Do not use to exhaust hazardous or explosive materials
and vapors.

2) To reduce the risk of fire, use only metal ductwork. Sufficient air is needed for proper
combustion and exhausting of gases through the flue (chimney) to prevent back drafting.

3) 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 code authorities.

4) Activating any switch on may cause ignition or an explosion.

5) Due to the size and weight of this hood, two people installation is recommended.

ELECTRICAL SHOCK HAZARD – Can result in serious injury or
death. Disconnect appliance from electric power before servicing.
If equipped, the fluorescent light bulb contains small amounts of
mercury, which must be recycled or disposed of according to
Local, State, and Federal Codes.

Preparation before Installation

NOTE: TO AVOID DAMAGE TO YOUR HOOD, PREVENT DEBRIS FROM ENTERING THE

VENT OPENING.

- Decide the location of the venting pipe from the hood to the outside. Refer to Figure 1.

- A straight, short venting run will allow the hood to perform more efficiently.

- Try to avoid as many transitions, elbows, and long run as possible. This may reduce

the performance of the hood.

- Temporarily wire the hood to test for proper operation before installing.

- Peel protective film off the hood (if any).

- For installing under the cabinet with recessed bottom, attach 4-inch wide wood filler
strips (not included) on each side. Refer to Figure 2.

- Measure and create access opening for electrical wires under the cabinet.

- Cut the multi duct exhaust according to the size of the venting pipe. Refer to Figure 3.

MAINTENANCE

CAUTION: NEVER PUT YOUR HAND INTO THE AREA HOUSING THE FAN WHILE THE
FAN IS OPERATING.

For the optimal level of operation, clean the range hood surface, safety screens, and oil
containers regularly.

To Clean Hood Surface

CAUTION: NEVER USE ABRASIVE CLEANERS, PADS, OR CLOTHS.

*** Regular care will help preserve its fine appearance.

1) Use only mild soap or detergent solutions. Dry surfaces using soft cloth.

2) If hood looks splotchy (stainless steel hood), use an orange base cleaner to clean the
surface of the hood. Avoid cleaner to get on the control switches. Only spread a light
coating over the surface of the hood and leave on for a few minutes (do not leave on too
long or this may cause damage to hood finish). Use soft towel to wipe off the cleaning
solution, gently rubs any stubborn spots. Use a slightly damp towel to get rid of any
cleaning solution. Use dry soft towel to dry the hood.

3) To bring the glow back into a stainless steel finish, use a stainless steel cleaner.

4) DO NOT allow deposits to remain for long periods of time.

5) DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere to the
surface causing rust.

6) DO NOT allow salt solutions, disinfectants, bleaches, or cleaning compounds to remain
in contact with stainless steel for extended periods. Many of these compounds contain
chemicals, which may be harmful. Rinse with water after exposure and wipe dry with a
clean cloth.

To Clean Oil Containers, Safety Screens and Impellers

CAUTION: DRAIN OIL CONTAINER BEFORE OIL CAN OVERFLOW.

1) Normal Cleaning

- Spray a mild degreaser into the fan and turn on high speed. Liquid residue will

accumulate in the oil containers.

2) Cleaning Oil Containers

- Remove the oil container (round) by turning counter-clockwise.

- Remove the oil container (oval) by sliding forward.

- Wash with warm soapy water. Dry completely before returning into place.

- Top rack dishwasher safe.

3) Cleaning Safety Screens

- Remove the safety screen screw and slide the safety screen out.

- Wash with warm soapy water. Dry completely before returning into place.

- Top rack dishwasher safe.

To Replace Light Bulb

CAUTION: HALOGEN LIGHT UNIT MAY BE HOT! WAIT UNTIL UNIT IS COOL.

NOTE: DO NOT TOUCH HALOGEN LIGHT WITH BARE HANDS, WHICH MIGHT CAUSE
OVER HEAT AND SHORTEN THE LIFT OF LIGHT BULBS.

   

1. Make sure all controls are OFF, and range hood is unplugged.

2. Place the flat-head screwdriver into the groove between the halogen light glass covering
and the housing .

3. Gently separate glass covering from the housing .

4. Gently pull out the defective light bulb  and discard. Light bulbs should be 12V 20W
maximum.

5. Wear a glove or use a cloth to hold the new light bulb and push securely into light
socket. NOTE: DO NOT PUSH TOO HARD OR YOU MAY BREAK THE BULB
CONNECTOR.

6. Put back halogen light glass cover .

7. Plug back power cord and turn on range hood to test for operation.
