SHEETMETAL INSTALLATION
Air Distribution and Duct Work
The F72 operates most efficiently when all of the
system air is delivered across the electronic cell at
a uniform velocity. Turning vanes should be
added to any return airdrop upstream from the air
cleaner (Fig. 3).
Gradual transitions to the F72 cabinet are
recommended in all duct work larger or smaller
than the cabinet opening. If transitions are used,
they should not exceed 20 degrees (4 in. rise per
linear ft. [101.6 mm rise per linear 304.8 m]).
INSTALL AIR CLEANER
Mount the F72 air cleaner as follows:
1. Fabricate and install the necessary vanes and
transitions.
2. Set the cabinet in position. If hanging
brackets are used, make certain the brackets
are strong enough to hold the cabinet and the
cabinet is attached firmly to the brackets.
NOTE: Place a spirit level on top of the cabinet
to make sure it is level.
3. a. Drill holes for sheet metal screws into the
cabinet face and also the duct.
b. Fasten the duct to the inside of the cabinet
flange opening with sheet metal screws.
c. Seal all joints in the return air system to
prevent dust from entering the clean air
stream.
Install the F72 components as follows:

CORRECT CELL POSITION IN
THE F72
1. Slide the prefilter(s) and post filter(s) into
place.
2. Insert the electronic cell(s) into the cabinet
with the cell handle facing the door opening.
Make certain the arrow stamped on the cell(s)
points downstream (Fig. 5).
WIRING
- CAUTION -
Disconnect the power supply before installation to
prevent electrical shock and equipment damage.
