GREASEFILTERS
MAINTENANCE
Grease Filters
The grease filters should be cleaned fre-
quently. Use a warm detergent solution.
Grease filters are dishwasher safe.
See “Install Filter” section for installation and
removal instructions.
Ductfree Filters
The ductfree filters should be changed every 6 months. See “Install Filter” section
for installation and removal instructions.
Hood Cleaning
Stainless steel is one of the easiest materials to keep clean. Occasional care will
help preserve its fine appearance.
Cleaning tips:
•Hot water with soap or detergent is all that is usually needed.
•Follow all cleaning by rinsing with clear water. Wipe dry with a clean, soft cloth
to avoid water marks.
•For discolorations or deposits that persist, use a non-scratching household
cleanser or stainless steel polishing powder with a little water and a soft cloth.
•For stubborn cases, use a plastic scouring pad or soft bristle brush together
with cleanser and water. Rub lightly in direction of polishing lines or "grain" of
the stainless finish. Avoid using too much pressure which may mar the surface.
•DO NOT allow deposits to remain for long periods of time.
•DO NOT use ordinary steel wool or steel brushes. Small bits of steel may
adhere to the surface causing rust.
•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.
Painted surfaces should be cleaned with warm water and mild detergent only.

INSTALL THE DUCTWORK
Ductedconfigurationonly.
NOTE: To reduce the risk of fire, use only
metal ductwork.
1. Decide where the ductwork will run between
the hood and the outside.
2. A straight, short duct run will allow the hood
to perform most efficiently.
3. Long duct runs, elbows, and transitions will
reduce the performance of the hood. Use
as few of them as possible.
4. Install a roof or wall cap. Connect 6" round
metal ductwork to cap and work back to-
wards hood location. Use duct tape to seal
the joints between ductwork sections.
