LOCATION

Use the following guidelines to select a suitable location for
these units.

1.

Unit is designed for outdoor installation only.

2.

Condenser must have an unlimited supply of air. Where 
a choice of location is possible, position unit on either 
north or east side of building.

3.

For ground level installation, a level pad or slab should 
be used. The thickness and size of the pad or slab used 
should meet local codes and unit weight. Do not tie the 
slab to the building foundation.

4.

For roof top installation, be sure the structure will support 
the weight of the unit plus any field installed components. 
Unit must be installed on a level roof curb or appropriate 
angle iron frame providing adequate support under the 
compressor/condenser section.

5.

Maintain level tolerance of unit to 1/8" maximum.

CLEARANCES

All units require certain clearances for proper operation and
service. Refer to Table 10 for the clearances required for
combustion, construction, servicing and proper unit opera-
tion.

RIGGING OR HANDLING

Care must be exercised when moving the unit. Do not
remove any packaging until the unit is near the place of
installation. Rig unit with slings placed under the unit.
Spreader bars of sufficient length should be used across the
top of the unit.

Units may also be moved or lifted with a fork-lift. Slotted
openings in the skid are provided for this purpose. Forks
must pass completely through the base.

Refer to Table 2 for unit weights and to Figure 1 for approxi-
mate center of gravity. 

 

Excessive exposure of this furnace to contami-
nated combustion air may result in equipment
damage or personal injury. Typical contaminates
include: permanent wave solution, chlorinated
washes and cleaners, chlorine based swimming
pool chemicals, water softening chemicals, carbon
tetrachloride, halogen type refrigerants, cleaning
solvents (e.g. perchloroethylene), printing inks,
paint removers, varnishes, hydrochloric acid,
cements and glues, antistatic fabric softeners for
clothes dryers, masonry acid washing materials.

Do not permit overhanging structures or shrubs to
obstruct the condenser air discharge, combustion
air inlet or vent outlet.

Before lifting a unit, make sure that its weight is
distributed equally on the cables so that it will lift
evenly.
