OPERATION
Controls
The hood is operated using the (4) push-
buttonslocatedateye-level, onthe frontedge
of the hood.
The light switch turns the halogen lights
on and off. Push the light switch once to
turn the lights ON - push a second time to
turn the lights ON to a brighter level - push a
third time to turn the lights OFF.
The timer switch turns the blower timer on and off. Push this switch once to turn the
timer ON. With the blower timer turned ON, the speed that was selected will blink in
the display; if the speed selection is changed the blower timer will remain ON; the
blower will shut OFF after 10 minutes.
The display indicates:
- indicates the selected motor speed (from 1 to 4);
- indicates Timer On when the number blinks;
- indicates Filter Alarm when the central segments is on or blinking.
The blower switch turns the blower on and off. Push the switch once to turn the
blower ON (turns on to last speed selected). Pushing the switch sequentially selects
blower speeds from 1 to 4. To turn OFF the blower, push and hold the blower switch
for approximately 2 seconds.
The reset switch resets the grease filter or charcoal filter alarm. The grease filter
must be cleaned when the center segment of the display lights up continuously or
blinks. The filter alarm will be seen in the DISPLAY for approximately 30 seconds
after the blower is turned off. To reset the hour counter, keep the switch pressed for
2 seconds when the alarm can be seen in the DISPLAY.
HEAT SENTRY™
Your hood is equipped with a HEAT SENTRY™ thermostat. This thermostat is a
device that will turn on or speed up the blower if it senses excessive heat above
the cooking surface.
1) If blower is OFF - it turns blower ON to HIGH speed.
2) If blower is ON at a lower speed setting - it turns blower up to HIGH speed.
When the temperature level drops to normal, the blower will return to its original
setting.
WARNING
The HEAT SENTRY thermostat can start the blower even if the hood is turned
OFF. When this occurs, it is impossible to turn the blower OFF with its switch.
If you must stop the blower, do it from the main electrical panel.

MAINTENANCE
Proper maintenance of the Range Hood will
assure proper performance of the unit.
Grease Filters
Grease filters should be cleaned when the
light switch flashes or remains lit when the
blower is off (i.e. 30 hours of operation). Use
a warm detergent solution to clean filters.
Filters are dishwasher safe. See page 14 for
filter removal and installation instructions.
Non-ductedRecirculation Filter

be changed when the light switch flashes or
remains lit when the blower is off (i.e. 120
hours of operation). See page 14 for filter
removal and installation instructions.
HoodCleaning
Stainless steel is one of the easiest materials
to keep clean. Occasional care will help pre-
serve 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.
●Fordiscolorationsordepositsthatpersist,use anon-scratching householdcleanser
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
cleaser 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 com-
pounds contain chemicals which may be harmful. Rinse with water after expo-
sure and wipe dry with a clean cloth.
Painted surfaces should be cleaned with warm water and mild detergent only.

INSTALL THE DUCTWORK
(DUCTEDHOODSONLY)
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. Astraight,shortductrunwill allowthehood
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. Larger
ducting may be required for best
performance with longer duct runs.
4. Install a roof or wall cap. Connect round
metal ductwork to cap and work back to-
wardshoodlocation. Useducttapeto seal
the joints between ductwork sections.

WARNING: Electrical wiring must be
done by a qualified person(s) in
accordance with all applicable codes and
standards. This range hood must be
properly grounded. Turn off electrical

1. Plan where the hood will be located
above the cook top. Refer to the
INSTALL MOUNTING BRACKET
section for hood mounting height
options.
2. Install a standard 2” x 4” wall outlet box
and 3-blade 125 Volt, 15Amp grounded
receptacle.
3. Mount the receptacle 20” to 26” above
the bottom of the hood Fig. 3
