VentAHood Magic Lung Configuration guide

Cleaning Your
Fire
-
Safe “Magic Lung
®
” Blower
As
contaminated air passes through the
Magic Lung
®
blower system, vaporized cooking grease is
“squeezed” back into liquid form inside the snap
-
off blower housing
. From there,
it flows through a hole into
an
E
-
Z Clean grease tray.
The amount and type of cooking you do will determine how often your E
-
Z Clean
grease tray, blower housing and blower wheel(s) require cleaning. The grease tray will require cleaning more
often than the blower housing and blower wheel
(s).
Because your Vent
-
A
-
Hood extracts over 99% of the cooking grease from the air, you are assured
that grease is not building up inside your ductwork (a bad fire hazard), or inside your home (smelly and very
destructive to carpeting, upholstery and the f
inish o
n cabinetry). Do not use any acids, abrasives, strong
detergents,
solvents
or scouring pads
to clean your hood.
SPECIAL NOTE ON DUAL BLOWERS
:
If there are two or more blowers in your Vent
-
A
-
Hood, you
will find white motor/blower wheel combinations
and black motor/blower wheel combinations. White mot
ors
turn clockwise and black
motors turn counter
-
clockwise. Consequently,
the curved fins on the black
and
white blower wheels face opposite directions so the air can be “scooped” toward the outside.
In w
all
-
mounted
hoods, the white motor/blower wheel are installed on the right. In island, peninsula or pass
-
thru hoods, the
white motor/blower wheel are installed on the left, as you face the front of the hood
.

When they are new,
you may wish
to scratch a “B”
into the me
tal on the back of the black
blower
wheel and a “W” into the back of the
white blower wheel because, after a period of time, the grease and
cleaning may obliterate the paint.
Take care to always keep the motors and wheels in their proper
locations!
Placing a blower wheel and/or motor in the wrong location may cause the motor to
overheat and
prematurely burn out. Your Vent

Hood will also become noisy and won’t ventilate properly.
CLEANING STEPS
:
1).
Frequently
clean the grease from the drip pan incorporated in the
blower shield. Using two hands, hold the blower shield level
as you
carefully pull it
straight toward you. Once the shield is free from the
retaining pins,
continue to hold it level as you lower it from the hood
.
Periodically
clean the blower housing, damper(s) and blower wheel(s).
Remove
the blower housing by
un
-
snapping the latches on each side
then, while tipping it slightly downward, pull it forward to clear the blower
wheel(s).
Locate
and remove the polymer damper
(
s
)
located inside the
blower housing.

2). Clean the blower housing, blower shield an
d dampers
by soaking in a sink
of hot, soapy water for about 5 minutes. Formula 409 and WD40 are
also good
at liquefying greas
e. T
hese
parts
may be washed
in the
dishwasher but be aware,
the detergent may deteriorate the paint
over time
and this is not a
warranty issue
.
3). To remove the motor/blower wheel assembly from the hood, undo the three
screws that attach the round, motor mounting plate to the hood (see figure 2).
Motor mounting plates are
color
coded either white or black
to match their
co
rrespond
ing blower wheel
s
. Disconnect
the motor
from its
wiring harness
and
remove. (
NOTE:
M
otors are
permanently lubricated and do not need to be oiled)
.
Figure 2
4).
Handle blower wheels
carefully
. They can be damaged beyond
repair
by twisting, bending
or dropping them! Also, do not disturb any
metal
clips attached to the fins (see figure 3). These clips balance the
wheels
Figure 3
and must not be moved!
Using an 1/8” allen wrench (see figure 4), loosen the set screw in the hub
of the blowe
r wheel (see figure 5). If the set screw is loosened and the
blower
wheel does not slide
easily off of the motor shaft, it may be due to a grease
build
-
up
on
the shaft. Clean this grease from the shaft with a liquid penetrating
Figure 4
oil, such as WD40,
and the blower wheel will slide off easily.
5). G
rease can be removed from the blower wheel by soaking
it in a hot detergent or ammonia water solution, scrubbing it with
a soft brush, and then rinsing.
Keep the motor dry.
If it is not too greasy, t
he blower wheel may be cleaned
in the dishwasher. However, the dishwasher detergent may
eventually take the paint off the wheel.
Figure 5
If you have a dual blower, permanently mark the blower
wheels, as described above, so you will always be
able to
distinguish the white wheel from the black
.
Take care to reinstall the motors and wheels in their
proper locations!
6). Line up the set screw with the flat side of the motor shaft and slip the blower wheel onto the shaft.
Position the wheel
sl
ightly
away from the motor.
NOTE:
Placement of the wheel is important!
Do not leave it
too far forward or it will rub on the blower housing when it is replaced in step #9. Using the allen wrench,
tighten the set screw against the flat side of the motor sha
ft.
7). Spin the wheel by hand to see that it does not touch the motor and does not wobble. A blower wheel that
wobbles needs to be replaced.
8). If you have taken it out of the hood, reinstall the motor/blower wheel assembly.
9).
Reinstall the dampers in
the blower housing, making sure they open and close freely. Reinstall
the blower
housing and blower shield. Spin the blower wheel by hand to be sure it turns freely and is not scraping on the
housing. If the blower wheel rubs on the housing you will need t
o reposition the blower wheel on the motor
shaft.
