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 void 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 MATERIAL AWAY FROM FLAMES. If the flames do not
go out immediately, EVACUATE THE AREAAND CALLTHE FIRE DEPARTMENT or 911.
•NEVER PICK UPA BURNING PAN –You May Get Burned.
•DO NOT USE WATER, including wet dishcloths or towels –a 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, installation by 2 persons 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

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 (Figure 1).
A straight, short vent run will allow the hood to
perform more efficiently.
Try to avoid as many transitions, elbows, and long
runs as possible. Transitions, elbows and/or long
runs may reduce the performance of the hood.
Temporarily wire the hood to test for proper
operation before installing.
Important: Peel protective film off the hood and
duct covers, if any.
- Use duct tape to seal the joints between pipe
sections.
Hood Installation
CAUTION: USE HAND TOOLS ONLY. DO NOT
OVER TIGHTEN SCREWS. IT MAY CAUSE DAMAGE TO
THE HOOD.
CAUTION: If moving the cooking range is
necessary to install the hood, turn off the power in
an electric range at the main electrical box. SHUT
OFF THE GAS BEFORE MOVING A GAS RANGE.
And use a protective covering to protect cooktop
and/or countertop from damage.
1. Mark centerlines of cook top or range on ceiling.
Use centerlines marked on ceiling to position the
range hood as shown in Figure 2.
2. Cut and remove ceiling drywall. Install 2” x 4”
cross framing lumber (not provided) between
ceiling joists.
3. The framing should be spaced 9-1/2” at the front
centerline and 7-3/4” on the sides. Refer to Figure
3.
4. Finish the ceiling surface. Be sure to mark the
location of the ceiling joists and cross framing
lumber.
5. Cut a 7-1/2” duct opening and approximately a 1”
wire access hole. Secure four hood mounting
screws (not provided) into the ceiling joint and
cross framing lumber, leaving 1/8” away from the
cabinet as shown on Figure 4. Make sure screws
are driven into the ceiling at the middle of joists
and cross framing lumber for maximum support
and stability.

length of wiring to drop down from the ceiling to the
electric box.
13. Connect the electrical wires according to color
(green to green, white to white, and black to black)
and cap with wire connectors. Green wire must be
grounded to reduce risk of electric shock.
Ductwork Installation

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.
