4.8 INSTALLATION SITE PREPARATION. The air conditioner is designed so that it is adaptable to a variety of
installation arrangements. Most typical installations are made by preparing an opening in an exterior wall of the room or
enclosure to be conditioned and by positioning the air conditioner so that the front of the cabinet is inside the room or
enclosure and the back is outside. Alternate installations may be made with the entire cabinet either inside or outside the
4.8.1 General. The following are minimum requirements for all installations See fig. FO-1 for installation dimensions.
a. A relatively level surface capable of bearing the weight of the air conditioner on which to set the base. To insure
proper condensation drainage, the surface should be level within 5 degrees from front to back and side to side.
b. An unobstructed flow of air from outside the conditioned area to the inlet and outlet of the condenser.
c. An unobstructed flow of air from inside the conditioned area to the conditioned air mistake and discharge .
d. Access to the front of the cabinet for routine operation and servicing and for necessary maintenance actions.
e. Access to the front of the cabinet for removal of the return air filter.
f. A source of 208 Vac, 3-phase, 50/60 hertz input power rated at 24.4 amps. The power source outlet should be
located as near as possible to the installed location of the air conditioner. The power source wring 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.
g. An earth ground capable of handling 24.4 amps.
h. Check that no source of dangerous or objectionable fumes are located near the air inlets.
BEWARE of strange odors that could be caused by refrigerant leakage. In
case of leaks, ventilate area immediately and contact Direct Support
i. 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.
