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 hood must be vented to the outside.
a) Before servicing or cleaning unit, SWITCH POWER OFF AT SERVICE PANEL.
b) Clean fan, filter, if any, and grease laden surfaces frequently. To reduce the risk
of fire and properly disperse air, 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.
•Alwaysturn hood ON when cooking at high heat.
•Use high settings on cooking range ONLY when necessary. Heat the oil slowly on low to
mediumsetting.
•Do not leave cooking range unattended when cooking.
•Always use cookware and utensils appropriatefor 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 or filter.

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 dishclothsor towels – a violent steamblast 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) of fuel burning equipment to
prevent back drafting.
3) Follow the heating equipment manufacturer’s guideline and safety standards such as those
4) published by the National Fire Protection Association (NFPA), and the American Society for
5) Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and code authorities.
6) Two installers are recommended because of the large size and weight of this hood.
7) Activating any switch may cause ignition or an explosion.
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.

INSTALLATION
PLEASE READ ENTIRE INSTRUCTIONS BEFORE PROCEEDING
Calculation before Installation
To calculate installation, please refer to Table 1. (All calculation in inches.)
Preparations 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.
- Use duct tape to seal the joints between pipe sections.
- If necessary, prepare back wall frame with cross framing lumber for secure installation.
Using references in Table 1 and measurements on page 15, decide the level of the
lumber. Refer to Figure 2.
- Important: peel protective film off the duct cover and the hood (if any).
TABLE 1
A = Height of Floor to Ceiling
B = Height of Floor to Counter
Top (Standard: 36”)
C = Preferred Height of Counter Top to
Hood Bottom (Recommended 27”
to 30”)
D = Height of Hood
E = Height of the Hood
Installation [A – (B + C)]
F = Height of Duct Cover [E – D]
SAFETY WARNING
HOOD MAY HAVE VERY SHARP EDGES; PLEASE WEAR PROTECTIVE GLOVES IF
REMOVING ANY PARTS FOR INSTALLING, CLEANING OR SERVICING.

MAINTENANCE
CAUTION: NEVER PUT YOUR HAND INTO THE AREA HOUSING THE FAN WHILE THE
FAN IS OPERATING.
For optimal operation, clean range hood surface, stainless steel filter, and oil container
regularly.
To Clean Hood Surface
CAUTION: NEVER USE ABRASIVE CLEANERS, PADS, OR CLOTHS.
-Regular care will help preserve its 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 cleaner on the control switches. 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 away 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 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 Stainless Steel Filter / Oil Container
CAUTION: DRAIN OIL CONTAINER BEFORE OIL CAN OVERFLOW.
1) The oil container attached underneath stainless steel filter can be removed by turning
counter-clockwise.
2) To clean the stainless steel filter, remove the screws (leave in a safe place), and slide
stainless steel filter out.
3) Both oil container and stainless steel filter should be washed with warm soapy water
and dry thoroughly before returning in place. Both are top rack dishwasher safe.

13
To Clean Carbon Filter (Optional Recirculating Kit)
1) Turn oil container counter-clockwise. Shown in Figure 18.
2) Use a Philips screwdriver to take out the screws (2 pcs). Shown in Figure 19.
Figure 18 Figure 19
3) Remove the carbon filter from the two stainless steel filters.
Shown in Figure 20.
4) Place carbon filter into warm water with neutral detergent
and clean thoroughly. Dry and replace.
5) Re-install the carbon filter and the stainless steel filters.
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 protective covering as shown in Figure 21.
3) Gently pull out the defective light bulb and discard. Light bulbs should be 12V 20W
maximum. Refer to Figure 22. Push bulb securely into light socket.
4) Replace protective cover.
5) Plug in range hood.
