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. Vent-A-Hood®range hoods exhaust
all cooking by-products to the outside with the exception of
GREASE, which is collected by the patented Magic Lung®
blower system.
The Magic Lung Blower®- How It Works
TheMagic Lung®internalblowersystemwasoriginallypatented
in 1937. The Magic Lung®pressurizes grease-laden air as it
passes through the blower wheel and cools the grease from a
vapor into a liquid. The centrifugal action of the Magic Lung®
traps 99% of cooking grease without the use of messy and
inefcient wire mesh or bafe lters. The constant speed
centrifugalblowerisalsodesignedtocreatea pressurebarrier,
lowering the risk of an attic or wall re.

Operating Instructions
A. Models with Halogen Lights
On halogen light models, motors are switched independent from
one-another. The user should generally start with the hood on the
lowest setting, and then increase speed and/or turn on additional
motors as required.
RedSwitch -Thisswitchoperatesatwo-speedmotor.Thistwo-speed
motor allows the user to switch the hood to “LOW” (position I) for
quieter operation during light cooking, while the “HIGH” (position II)
setting delivers the full power of the Magic Lung®blower unit. If the
two-speedmotoris turned to“LOW”,theheatsensor(SensaSource®)
monitors cooking activity. If the heat reaches an unacceptable level
inside the hood, or a range re occurs, the two-speed motor will
switch from “LOW” to full power automatically. The sensor will return
the motor to the “LOW” level when the heat subsides or the hood
may be turned off manually (middle position).
Red Switch
White Switch - This switch controls the lights. “LOW” level lighting
(position I) is 25 watts per bulb, “HIGH” level lighting (position II) is
50 watts per bulb. Off is in the middle position.

blower housing(s) will need to be cleaned.
To remove the blower housing(s) and damper(s), rst remove the
blower shield (A). This is accomplished by loosening the two brass
screws on the bottom of the shield. The blower housing is removed
for cleaning by un-snapping the suitcase latches (B) (one on each
sideofthehousing).Then,pullthehousingforwardandgently“tip”it
downward to clear the blower wheel(s). The blower wheel(s) can be
removed (if necessary) by using the allen wrench that was provided
with this manual. See part C of this section for details on how to
clean the blower wheel(s).

Hood Cleaning (Continued)
Clean the shield(s), damper(s), and/or blower housing(s) in a sink
of warm soapy water (liquid dish detergent) and let soak for a
few minutes. Wash with sponge or dishcloth, rinse and let drain.
Reinstall blower housing and snap suitcase latches in place. The
blower housing and shield(s) 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 shield(s)
and blower housing(s).
Regular cleaning of the blower housing 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 (B).
Ininstanceswheretheblowerwheelmayneedtoberemoved,follow
the instructions below.
Removingthe blower wheelrequiresa1/8”hexwrenchwhichhasbeen
provided with this manual. There is a small set screw on the side of
the hub of the wheel (A) 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 wrench through the blades of the
blower wheel and into the set screw. 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®.

Page 10L023
Hood Cleaning (Continued)
After allowing the penetrating oil to soak for a few minutes, push
the blower wheel forward slightly, then gently pull the blower wheel
off the motor shaft. 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 (B).
Asoftbristletoothbrushwithwarmsoapywatermaybeusedtoclean
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, making
sure the back of the blower wheel does not touch the motor mount
screws protruding from the motor.
If the motor is too far back, it will rub the motor mount screws, and if
it is too far forward, it will rub the inside of the blower housing.Adjust
the blower wheel slightly to nd the correct front-to-rear location.
Tighten the set screw (clockwise) to lock the blower wheel in the
correct position.
NOTE:Forhoodsthathavemorethanoneblowerwheel,makesure
that white blower wheels are matched up with white motor rings,
and black blower wheels and matched up with black motor rings.
The hood will not perform properly if blower wheels and motors are
mismatched.
