Service Clearances
In addition to providing adequate space around the unit for
piping coils and drains, access to at least one side of the unit
is always required to allow for regular service and routine
maintenance, which includes filter replacement, drain pan
inspection and cleaning, fan bearing lubrication, and belt
adjustment. Provide sufficient space—at least equal to the
length of the coil—on the side of the unit for coil removal. See
Figure 1
for servicing space requirements.
Maintain at least 54" of clearance in front of electrical power
devices. Electrical power devices that are mounted on the side
of the unit typically are up to 12" deep
with multiple fans have motor control boxes up to 16" deep
when supplied with VFDs.

Rigging
Use all lifting points. Improper lifting can cause severe
personal injury and property damage.
Lifting points may not be symmetrical to the center of gravity
of the unit. Ballast or unequal cable lengths maybe required.
Skyline air handlers ship as separate sections, completely
assembled, or in modules of assembled sections. The unit
must be rigged as it ships from the factory. Do not rig units
after assembly. Units are provided with a factory-installed base
rail and can be lifted using the 2" diameter lifting holes located
in the corners of each shipping section. To prevent damage to
the unit cabinetry, use spreader bars. Position spreader bars
to prevent cables from rubbing the frame or panels. Before
hoisting into position, test lift for stability and balance. Avoid
twisting or uneven lifting of unit.
