The Importance of Cooking Ventilation
The main purpose of cooking ventilation is to capture the
by-products of cooking. These by-products are heat, steam,
smoke, odor, hazardous gases, and grease. Without proper
cooking ventilation, these by-products can cause a great deal
of harm to the home.

Hood Cleaning
A. Hood Canopy
Wipedowntheinteriorandexteriorofthehoodasneededwithasoft
cloth and warm soapy water (liquid dish detergent is acceptable). Do
not use acids, abrasives, strong detergents, solvents, or scouring
pads. Stainless steel should be treated with a quality stainless steel
cleaner such as Stainless Steel Magic®(Vent-A-Hood®part number
SS64). Follow all label instructions. Do not polish across the grain
or in circles.
B. Blower Unit
WARNING: To reduce the risk of personal injury, be sure the
power is turned off in the hood before removing the shield(s)
and blower housing(s).
The blower captures grease by-products in the grease pan attached
to the bottom of the blower. Cooking habits determine how often the
grease pan will need to be cleaned.
To remove the grease pan, unsnap the suitcase latches (A) (one on
each side of the pan).

Page 7 L026

Hood Cleaning (Continued)
The grease pan (B) may now be lowered from the hood.
Clean the grease pan in a sink of warm, soapy water (liquid dish
detergent) and let soak for a few minutes. Wash with a sponge or
dishcloth, rinse and let drain. Reinstall the grease pan and snap
the suitcase latches in place. The grease pan alternatively may be
placed into a dishwasher.
C. Blower Wheel
WARNING: To reduce the risk of personal injury, be sure the
power is turned off in the hood before removing the grease pan.
Regular cleaning of the grease pan should prevent grease
accumulation on the blower wheel. If grease build-up should occur,
the blower wheel may easily be cleaned in place using a soft bristle
toothbrush and a common degreaser such as Formula 409®. Take
carenottomoveorlosethemetalbalancingclipsthatmaybeafxed
to the wheel.
In instances where the blower wheel may need to be removed, follow
theinstructionsonthenextpage.

Hood Cleaning (Continued)
A soft bristle toothbrush with warm soapy water may be used to
clean the blades, or soak the blower wheel in warm soapy water.
When reinstalling the wheel onto the motor shaft, make sure the set
screwmakesdirectcontactwiththe“atspot”onthemotorshaft.
Slide the blower wheel onto the motor shaft as far as it will go and
tighten the set screw (clockwise) to lock the blower wheel in the
correct position.
Remove the grease pan as described in Hood Cleaning, Section
B. If the blower wheel needs to be removed, a 1/8” T-handle hex
wrenchisnecessary.AT-handlehexwrench(A)maybeobtained
from Vent-A-Hood®to accomplish this (Vent-A-Hood®part number
AW101). There is a small set screw on the side of the hub of the
wheelthattightensupagainsta“at”spotonthemotorshaft.Theset
screw must be turned ½turn counterclockwise to remove the blower
wheel. Insert the T-handle allen wrench through the guide hole (B)
locatednexttotheblowerhousinglatch,throughthebladesofthe
blower wheel, and into the set screw. Use caution to avoid bending
or distorting the blower wheel and take care not to move or lose the
metalbalancingclipsthatmaybeafxedtothewheel.Ifthewheel
isdifculttoremove,theareawherethemotorshaftmakescontact
with the blower wheel hub may need to be sprayed with a common
penetrating oil such as WD-40®.

Maintenance/Troubleshooting
Replacing the ARS Filter Components
1. Remove the duct cover front panel. The panel is held in place
with four snaps at the corners and at least one snap on the left and
right.Beginbypullingthepanelawayatonecornereitherwithnger
tips or a plastic utensil. Work around the duct cover disengaging
one snap at a time until all of the snaps are loose. Beware of sharp
corners and edges. Use caution to prevent bending, scratching, or
sropping the cover.
2. Liftthesmoketrappinglterupwardandremoveitforwardout
oftheductcover.Discardlterwithhouseholdrefuse.
3. Lift the odor absorbing canister by the handles. Raise the canister
so that the canister bottom is just above the bottom of the duct cover
opening and slide the canister out of the duct cover. Replace activated
carbonmediaordiscardlterwithhouseholdrefuse.
4. InstallnewltersfollowingtheinstallationproceduresintheARS
installation manual.
Replacing the Activated Carbon Media
1. Remove the odor absorbing canister by following the procedure
above.
2. Remove the screws holding the cover inside the top of the odor
absorbing canister.
3. Invert the odor absorbing canister over a household refuse
container. Shake the odor absorbing canister to remove all of the
activated carbon pellets.
4. Withtheodorabsorbingcanisterupright,relltheunitwiththe
new activated carbon pellets (Vent-A-Hood part number PARS-C).
Lightly shake or vibrate the odor absorbing canister to settle the
pellets. Fill all voids completely and leave a small mound of pellets
above the cover opening to allow for future settling.
5. Replace the cover using the screws that were removed in step
2 above.

A. Light Bulb Replacement
WARNING: To reduce the risk of personal injury, turn off power
and allow lights to cool before proceeding.
Toremovethebulb,turnitcounterclockwise.Ifthelightisdifcultto
remove, it may be necessary to use the light bulb suction cup that
has been provided with this manual.
Replace the bulb with a GU10 120 volt, 50 watt halogen bulb (Vent-
A-Hood®part number P1110).
B What To Do If...
Smoke is in the kitchen. Check the following:
Is the hood sized appropriately for the type of cooking equipment
it is ventilating?
The purpose of a hood is to collect cooking contaminants and hold
themuntiltheblowerunitcanexhaustthemtotheoutside.Therefore,
it is necessary to size the hood based on the type of cooking
equipment that is being used. Whenever possible, hoods should
overlap the cooking equipment by at least three inches on each
side. The hood should also project out to the front edge of the front
burners. Finally, the height of the hood can affect its performance.
Generally speaking, taller hoods are more suitable for professional
style ranges, whereas under cabinet hoods are recommended for
standard cooking equipment.
Does the blower capacity of the hood match the cooking
equipment it is over?
K250 Single Blower - For standard electric or small gas cooking
equipment.
Is the hood mounted at the appropriate height off of the cooking
surface?
The height of the hood off the cooking surface is very important. The
higher the hood is mounted, the less effective it will be. Hoods only
collect cooking vapors; they will not pull cooking contaminants back
into the hood if they escape unto the kitchen. Generally speaking,
the deeper the hood, the higher the hood can hang and still be
effective.
K Series Wall Mount 24”

Page 11 L026
Maintenance/Troubleshooting (Continued)
Is the hood making a rubbing or scraping noise?
This may be caused by the blower wheel coming in contact with the
blower housing. Refer to Hood Cleaning, Section C for blower wheel
installation details.
NOTE: If smoke still enters the kitchen after following these
suggestions, contact your dealer for additional service and/or
suggestions.
