Install Unit On Roof Curb
Check to see that all lifting brackets are secure and that the
rigging cables and straps are clear of door handles or any
other appendages of the unit.
The units have two inch interlocking splice collars at each
mating face. Care must be used so that the flanges engage as
the unit sections are mounted together. The units must be set
tightly together during lifting as the curb gasket will grip the unit
base and make moving the unit difficult.
Units with vestibules must be handled so that the lifting
bracket can be removed after the unit is placed on the curbing.
Remove the lifting bracket that projects inward over the
curbing. Save the self tapping bolts. When the adjacent section
is placed in position, use self tapping bolts to secure the bases
together as illustrated in
Figure 10
.
Complete cabinet by placing sealant over any areas that
appear to have remaining gaps. Install the cabinet top strips as

that is included with the air handler.
Assemble and install all air hoods in accordance with the
instructions that are provided with hood.

Installation of Piping and Wiring
CAUTION
The base section of each cabinet has a drip pan installed
below every panel that drains to the outside frame trough. Any
holes cut through the bottom of the unit must also penetrate
the drip pan. If holes are cut in the drip pan, they must be
sealed to prevent moisture leakage.
Be sure that all piping, wiring and control penetrations that are
made through the unit panels and floors are thoroughly sealed
on both the inside and outside of the cabinet.
A single metal thickness pan is provided in the bottom of the
vestibule. The pan can be removed if necessary. If holes are
cut into the pan for piping passage, the holes must be sealed
to prevent moisture leakage.
