The efficiency of your downdraft depends on
a clean filter.
Frequency of cleaning depends on the type
of cooking you do. Grease filters should be
cleaned at least once a month.
Never operate the downdraft without the filters
in place.
To remove: Lift up and pull the bottom out.
Remove the left filter first, then slide the
right filter to the left and remove it.
To clean: Soak and then agitate in a hot
detergent solution. Light brushing may be
used to remove imbedded soil. Rinse, shake
and remove moisture before replacing.
Filters may be cleaned by placing in
dishwasher, although some slight color
fading may occur after several washings.
With careful handling, the filter will last for
years. If replacement becomes necessary,
order the part from your dealer.
Cooking Tips
The high air movement of this downdraft
system can increase the cooking times for
some foods. It may take longer to reach
high cooking temperatures if the downdraft
is turned to high right away. Adjust the fan
speed for best cooking results.
For best results when heating oil for deep
frying or when boiling water, use the front
surface units or wait until the water is
boiling or the oil is at frying temperatures
before turning on the downdraft.
The downdraft may not completely capture all the
steam from pans on the front burners.
Canning
When canning foods in a water-bath canner,
a gentle but steady boil must be maintained
continuously for the required time.
When canning foods in a pressure canner,
the pressure must be maintained
continuously for the required time.
Use of the blower at HIGH speed when
canning may reduce the temperature
enough to stop boiling. While canning,
we recommend using the downdraft at
LOW speed and using the front surface unit.
Painted or metal surfaces
Grease filters
Do not use a steel-wool pad; it will scratch the
surface.
To clean the stainless steel surface, use a
hot, damp cloth with a mild detergent
suitable for stainless steel surfaces. Use a
clean, hot, damp cloth to remove soap.
Dry with a dry, clean cloth.
If food soil remains, try a general kitchen
cleaner, such as Fantastik®, Simple Green®,
or Formula 409®.
For hard-to-clean soil, use a standard
stainless steel cleaner, such as Bon-Ami®
or Cameo®.
Apply cleaner with a damp sponge. Use a
clean, hot, damp cloth to remove cleaner.
Dry with a dry, clean cloth. Always scrub
lightly in the direction of the grain.
After cleaning, use a stainless steel polish,
such as Stainless Steel Magic®, Revere
Copper and Stainless Steel Cleaner®, or
Wenol All Purpose Metal Polish®. Follow
the product instructions for cleaning the
stainless steel surface.

Installation Possibilities
When the kitchen design calls for an against the wall
installation, move 24″deep base cabinet forward,
3″to 5″. Filler panels can be angled or flat to fill the
space between adjacent cabinets.
In an island or peninsula, the countertop can be extra
deep to provide seating opposite of the cooktop.
Adding base cabinets on each side of the cooktop
provides extra storage and countertop work space.
Advance Planning—Clearances
■Installation must conform with local codes.
■The downdraft system with blower, motor and
duct work will occupy the cabinet below the
countertop and cooktop.
■The blower/motor assembly can be located below
the cabinet floor. The assembly will fit between
16″floor joists.
■ –In this installation a transition to 6 ″ round is required.
■The blower motor assembly can also be installed
outdoors. Order JXBC57 for remote blower
installations outdoors.
■Refer to “Cooktop Clearances” for information
on appropriate placement and necessary
clearances when planning installation.
■Refer to your specific cooktop installation
instruction for other appropriate clearances.
■Avoid placing cabinetry directly above the
cooking surface when possible.
If cabinetry is used above the cooking surface:
–Installation must conform with local codes.
–Use cabinets no more than 13″ deep.
–Maintain 30″minimum clearance between cooktop
and unprotected cabinets directly above cooktop.
–If clearance is less than 30″, protect cabinet
bottoms with flame-retardant millboard at least 1/4″
thick or gypsum board at least 3/16″thick covered
with 28 gauge sheet steel or .02″thick copper.
–Clearance between cooktop and protected
cabinetry must not be less than 24.″

Install Raise/Lower Switch
WARNING: Disconnect electrical power from
the unit before beginning switch installation.
Failure to do so could result in personal injury or
damage to the electrical controls.
Determine the location for the RAISE/LOWER
switch. The wiring lead is 72 ″ long.
■Drill a 3/16″hole into the desired location.
■–If the switch is mounted into a tile surface,
drill the hole between the tiles. Use locally
approved caulking to cover any gaps.
■Center the mounting bracket over the hole and
mark pilot holes. Remove the bracket and drill
pilot holes.
■Mount the metal switch bracket with screws
(not provided, choose screws for your type of
countertop or use locally approved adhesive).
■Tie a knot in the lead as close to the switch as
possible. This will prevent the lead from being
pulled away from the switch.
■Thread the wire lead through the trim mounting
bracket and the top of the countertop as shown.
■Pull the wire through the hole from the
underside of the countertop and thread the
wire lead into the end of the wire box.
■Peel film from the back of the cover trim to
expose the adhesive. Press trim onto the
mounting bracket to set the adhesive.
■Peel film from the back of the RAISE/LOWER
pad to expose the adhesive. Align with the
impression and press to set the adhesive.
■Remove protective coating from the top of the
trim frame.
IMPORTANT: Do NOT connect wire leads to
white connector until you have threaded the
lead through the countertop hole and through
the end of the wire box.
■Push wire metal leads into the white connector
plug. Pull wire through the box leaving about
2″additional length.
■Place plastic strain relief over the wire;
the wire should be flat and fit into the area.
Do NOT pinch or twist the wire. Snap the strain
relief closed.
■Push the strain relief into the hole on the wire
box. It will snap into position.
■Secure wire box to vent with screws provided.
■Coil the excess wire and position away from
moving parts and cabinet contents.

Installing the Cooktop
■With the Downdraft in the “Down” position,
place the cooktop into the cutout.
■Push the cooktop back until the back edge of
the cooktop just barely touches the front edge
of the downdraft cover.
■Using a dime as a thickness gauge, align the
cooktop so that there is a minimum uniform
gap of 0.05″(the thickness of a dime) between
the cooktop and the downdraft cover.
NOTE: Do not force the downdraft cover to move
rearward when aligning the cooktop. This may
cause the downdraft cover to impact and damage
the cooktop when the vent is raised and lowered.
NOTES:
■Accurate alignment of cooktop and downdraft
is necessary to ensure that there is no
interference when air vent is raised and
lowered. There should be a gap of 0.05″
(the thickness of a dime) between the back
edge of the cooktop and the front edge of
the downdraft cover.
■Radiant cooktops cannot be flush mounted
when using this downdraft vent.
