Note: Add 2.5 amps for each warming light and 0.5 amp for each halogen light.
Because the Magic Lung uses centrifugal filtration rather than conventional baffle or mesh filters, the Magic Lung blower can handle cooking equipment with higher cubic feet per minute (CFM) requirements and can deliver equivalent CFM much more efficiently
than other than other filtration systems. When comparing the Magic Lung with other blower units made by other manufacturers, use the “Equivalent CFM”.

Installation Details Continued
4) Remove the hood from its packaging and place the back of the hood on the floor or countertop in front of the wall
where it will hang.
5) Remove the blower shield(s) (A) by loosening the two brass screws on the bottom of the shield. Gently close the back
draft dampers from the top side of the hood. To remove the blower housing(s), unsnap the suitcase latches (B) (one on
each side of the housing). The housing(s) should be pulled forward and gently “tipped” to clear the blower wheels and
then out of the hood.
7) Install an appropriate 1/2” UL listed electrical wire clamp through each motor box electrical opening on top of the
hood. Install electrical wiring from the service panel to the hood location for each motor box. Consult the connection
diagrams (on previous page) for further details on electrical placement. Extend wire to the hood. Electrical connection(s)
will occur before the hood is installed on the wall.
7) Remove the three screws retaining the blower motor(s).
Unplug and remove the motor(s), taking care not to damage
the blower wheel(s). It is not necessary to remove the blower
wheel from the motor.
Warning: Make sure power is off and locked at the service disconnecting
means on the service panel during installation.
8) Remove the duct cover from its packaging. Remove and save the screws from the base of the duct cover. Place the
duct cover into the top of the hood and secure it temporarily to the hood with the screws previously removed. Lift the
hood and hold in place on the wall in the location where it will be installed. Lightly mark the wall with a short horizontal
mark along the bottom edge of the hood.
9) Remove the hood and duct cover assembly from the wall. On the back side of the hood, measure the distance between
the bottom edge of the hood and the top edge of the wood mounting strip. Measure this distance above the horizontal
line made in Step 8 and lightly mark the wall with a level, horizontal line. Measure where the center (left to right) of the
hood will be and mark the upper horizontal line on the wall with a short vertical centerline.
10) Remove the screws inside the top of the back of the hood that retain the wood strip that is recessed in the mounting
channel. Note: Some retaining screws may be located behind the blower(s). Remove the wood mounting strip from the
back of the hood and place the top edge of the strip on the upper, level horizontal line on the wall. Referencing the
vertical centerline from Step 9, place the mounting strip so it is centered (left to right) on the wall in the space where
the hood will be located. Drill pilot holes in the strip to prevent splitting. Using proper hardware, attach the mounting
strip to at least two wall studs.
