Remember that allowance must be made for the grille
to swing down so that the cell can be removed by
pulling it straight out of the cabinet. (Figure 9).

If the duct work to be used is larger or smaller than the
recommended framing sizes, a transition should be
installed between the duct work and the air cleaner to
insure maximum filtering efficiency. The expansion or
contraction rate of the transition should not exceed the
ratio of 1 to 3. (See figure 10.)
Once the duct connection to the framing is completed,
the air cleaner frame (cabinet) may be inserted into the
framing cavity.
Before inserting the cabinet, one of the three knock-
outs (figure 15) should be removed for insertion of the
120 VAC input wiring.
After properly positioning the cabinet, it may be fas-
tened to the framing either by using the mounting holes
in the inside walls of the cabinet or the mounting holes
in the front flanges of the unit.
