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 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 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:
1. 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.
2. Always turn hood ON when cooking.
3. Use high settings on cooking range ONLY when necessary.
4. Do not leave cooking range unattended when cooking.
5. Always use cookware and utensils appropriate for the type and amount of food prepared.
6. Use this unit only in the manner intended by the manufacturer.
7. Before servicing, switch power off at service panel and lock service panel (if possible) to prevent
power from switching on accidentally.
8. Clean ventilating fan frequently.

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 MATERIALAWAY FROM FLAMES. If the flames do not go
out immediately, EVACUATE THE AREAAND CALLTHE 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 ClassA, 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.

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.
Figure 1
Telescopic Stack Installation
Note: Duct cover with telescopic stack sold separately.
1. Mark centerlines of cook top or range on ceiling above. Use centerlines marked on ceiling to
position the mounting template as shown in Figure 2.
2. Remove and save template. Cut and remove ceiling drywall. Install 2” x 4” cross framing lumber
(not provided) between ceiling joists. Refer to Figure 3. Consult a professional if you have
difficulty or your installation is unique.
3. Finish the ceiling surface. Be sure to mark the location of the ceiling joists and cross framing, or
replace the mounting template in the position of the ceiling joists & cross framing.
4. Attach the telescopic stack to the ceiling and securely fasten to the joists and cross framing with
eight screws (not provided) as shown in Figure 3. Make sure screws are driven into center of
joists and cross framing for maximum support.
5. Adjust the telescopic stack using reference Fcalculated in Table 1 and measurements on page
15-16. Tighten from the side with eight (4x8 mm) screws (provided) as shown in Figure 4.

MAINTENANCE
For optimal performance, clean the range hood surface and baffles 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 a stainless steel cleaner to clean the surface of
the hood. Avoid getting cleaning solution onto or into the control panel. Follow directions of the
stainless steel cleaner. Caution: Do not leave on too long as this may cause damage to hood
finish. Use soft towel to wipe off the cleaning solution, gently rub off any stubborn spots. Use
dry soft towel to dry the hood.
3. DO NOT allow deposits to accumulate or remain on the hood.
4. DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere to the surface
and cause rusting.
5. 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 lint free cloth.
For Baffle Filter models only: to Clean Baffle Filter/Oil Tunnel
CAUTION: DRAIN OIL FROM BAFFLE FILTERS, SPACERS & OIL TUNNEL REGULARLY TO
PREVENT OVERFLOW.
1. Remove all the baffle filters, spacers and oil tunnel.
2. Using a sponge, wash with warm soapy water. Dry completely before returning into place.
CAUTION: SHARP EDGES
(Note: Baffle Filters are top rack dishwasher safe.)
