through the fi lter(s) before entering this unit. (See
Routine Maintenance for Installation/Removal
of air fi lters).
Removal of Internal Filter Rack — First remove
the Return Air Panel from the unit. Remove the
height adjustment screw from the inside of the
rack, and the (1) screw securing the assembly
to the coil located on the left leg of the rack. The
assembly can easily be collapsed and removed
from the unit. See Figure 3a for fi lter rack securing
screw locations.
Condensate Drain — Condensate is removed
from the unit through the 3/4" female pipe fi tting
located on the front side of the unit. (See Figure
4.) Install a 2 inch condensate trap in the drain
line of the same size and prime with water. When
connecting rigid drain line, hold the female fi tting
with a wrench to prevent twisting. Do not over-
tighten! Refer to local codes and restrictions for
proper condensate disposal requirements.
UNIT INSTALLATION
Ground Level — When installing the unit at
ground level, provide a concrete mounting pad
separate from the building foundation. The
pad must be level to insure proper condensate
disposal and strong enough to support the unit's
weight. Refer to Figure 2 . Make sure the slab
is a minimum of 2" above the grade and in an
area that drains well. (Figure 5)
All panels must be securely in place
when rigging and hoisting.
Rigging and Hoisting — The unit should be lifted
using slings and spreader bars. The spreader
bars are necessary to prevent damaging the top
of the unit's cabinet. Make sure that the lifting
equipment is adequate for the load. Refer to
Figure 2 for unit weights. Keep the unit in an
upright position at all times. For rooftop instal-
lations, remove and discard the two supports
attached beneath the unit.
