Access to the top of the cabinet for removal of the return air filter.
(8)
A source of 208 V ac, 3-phase, 50/60 hertz input power rated at 60 amps. The power source outlet
should be located as near as possible to the installed location of the air conditioner. The power source
wiring must include a disconnect switch. However, provisions should be made to insure that power is
not disconnected during normal operation and that the disconnect is not used to turn off the air
conditioner for normal shutdown.

An earth ground capable of handling 60 amps.
(10)
Remove four shipping bolts from evaporator motor fan mounting bracket (refer to Figure FO-2 ).
(11)
Check that no source of dangerous or objectionable fumes is located near the fresh air intake.

If possible, make use of terrain features such as trees and buildings to provide a shaded location. This
will minimize the cooling load on the air conditioner.
(13)
If possible, avoid locations where the condenser and fresh air intakes will be laden with dust, dirt, soot,
smoke, or other debris.
b.
Inside Installation. Manufacture an arrangement of ducts for the condenser intake and discharge air
openings, and the fresh air intake.
NOTE
Easy access to fresh or return air filters must be provided. Filters may be left in position
in unit or relocated in duct work. Some installations (filters relocated in duct work) may
require different size filters. Access to underside of air conditioner is required for
electrical, ground wire, drain line, etc.
c.
Outside Installation. Manufacture an arrangement of ducts for the conditioned air intake and discharge air.
Ducts may be made for attachment to the air conditioner cabinet using the mounting holes for the
conditioned air intake or some other arrangement may be made. Ducts may also be made for installation of
conditioned air intake on the inside ends or replacements ducts may be used. Prepare appropriate openings
in the wall for the ducts.
