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) Before servicing or cleaning unit, SWITCH POWER OFF AT SERVICE PANEL.
4) Clean fan, filter, if any, and grease laden surfaces frequently.
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.

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, charcoal filter unit, 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 Charcoal Filter Set and Oil Containers
CAUTION: DRAIN OIL CONTAINER BEFORE OIL CAN OVERFLOW.
1) Cleaning Charcoal Filter Set
- Remove the safety screen screw and slide the charcoal filter set out. Remove oil
container (round) by turning counter-clockwise.
- Wash with warm soapy water. Dry completely before returning into place.
- Top rack dishwasher safe.

12
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 on Figure 13.
3) Gently pull out the defective light bulb and discard. Light bulb should be 12V 20W
maximum. Refer to Figure 14. Push bulb securely into light socket.
4) Replace protective cover.
5) Plug in range hood.
