- 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, baffles/filters 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, baffle/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.
- 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 and
baffles/filters.

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.

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.

Preparation before Installation
NOTE: TO AVOID DAMAGE TO YOUR HOOD, PREVENT DEBRIS FROM ENTERING THE
VENT OPENING.
- Decide the location of 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.
- Temporarily wire the hood to test for proper operation
before installing.
1. If necessary, prepare back wall frame with cross
framing lumber for secure installation. Using
references in Table 1 and measurements on page 12,
decide the level of the lumber. Refer to Figure 2.

MAINTENANCE
SAFETY WARNING
NEVER PUT YOUR HAND INTO AREA HOUSING THE FAN WHILE THE FAN IS
OPERATING.
For optimal operation, clean range hood surface and stainless steel baffle filters regularly.
Cleaning Hood Surface
CAUTION : NEVER USE ABRASIVE CLEANERS, PADS, OR CLOTHS.
Regular care will help preserve the appearance of the hood.
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. 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 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 extended periods.
5) DO NOT use ordinary steel wool or steel brushes. Small bits of steel adhering to the
surface may 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 wipe
dry with a clean cloth.
