IMPORTANT SAFETY INSTRUCTIONS
- PLEASE READ THIS SECTION CAREFULLY BEFORE INSTALLATION -
WARNING – TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR PERSONAL INJURY,
OBSERVE THE FOLLOWING:
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 fan, optional filter and 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 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.
- KOBE RANGE HOODS will not be held responsible for
any damages to personal property or real estate or any
bodily injuries whether caused directly or indirectly by
the range hood.
WARNING – TO REDUCE THE RISK OF PERSONAL INJURY IN THE EVENT OF A RANGE
TOP GREASE FIRE:
Keep fan, filter, if any, and grease-laden surfaces clean.
Always turn hood ON when cooking at high heat.
Use high settings on cooking range ONLY when necessary. Heat the oil slowly on low to
medium setting.
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 fans frequently. Grease should not be allowed to accumulate on fan,
filter, and oil containers.

What to Do In The Event Of a Range Top Grease Fire
-SMOTHER FLAMES with a close 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.

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.
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 may cause ignition or an explosion.

SAFETY WARNING
HOOD MAY HAVE VERY SHARP EDGES; PLEASE WEAR PROTECTIVE GLOVES IF IT
IS NECESSARY TO REMOVE ANY PARTS FOR INSTALLING, CLEANING OR
SERVICING.
Preparations of Ductwork and Location
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.
-Use duct tape to seal the joints between pipe sections.

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, filter set, 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 getting cleaning solution 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 rub off 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 and cause 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 dry with a clean
cloth.
To Clean Filter Sets and Oil Containers
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 (round).
2) Cleaning Oil Containers
- Remove the oil container by turning counter-clockwise.
- Wash with warm soapy water. Dry completely before returning into place.
- Top rack dishwasher safe.
3) Cleaning Filter Set or Charcoal Filter Set
- Remove the safety screen screw and slide the filter set or charcoal filter set out.
- Remove oil container by turning counter-clockwise.
- 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.
1) Make sure all control switches are off, and range hood is unplugged.
2) Use a flat head screwdriver to pop out the protective covering as shown in Figure 10.
3) Gently pull out the defective light bulb and discard. Light bulb should be 12V 20W
maximum. Refer to Figure 11. Push bulb securely into light socket.
4) Replace protective cover.
