SITE AND SHELTER REQUIREMENTS.
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
positioning the air conditioner so that the front of the cabinet is inside the room or enclosure and the back of the
cabinet is outside. Alternate installations may be made with the entire cabinet either inside or outside the
conditioned area. The following are minimum requirements for all installations:
a. A relatively level surface capable of bearing the weight of the air conditioner on which to set the base. To
insure proper condensate drainage, the surface should be level within 5 from front to back and side to side. See
b. An unobstructed flow of air from outside the conditioned area to the intake and discharge of the
condenser fan (back face of air conditioner).
c. An unobstructed flow of air from inside the conditioned area to the conditioned air supply and discharge
openings (front face of air conditioner).
Check that no source of dangerous or objectionable fumes is near the fresh air
intake which could cause harm to personnel.
d. An unobstructed flow of air from outside the conditioned area to the fresh air damper intake and/or CBR
filter intake, if installed (back face of air conditioner).
e. Access to the front and back of the air conditioner for routine operation and servicing and for necessary
f. Access to and sufficient headroom to allow removal of the top panel is necessary, if the unit is to be
serviced when installed.
g. A source of 208 volt, 3 phase, 50/60/400 hertz input power rated at 18.0 amps or 230 volt, single phase,
50/60 hertz input power rated at 30.0 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.
h. An earth ground capable of handling 18.0 or 30.00 amps as applicable (10 AWG wire minimum).
i. If possible, make use of terrain features such as trees and buildings to provide a shaded location. This
minimizes the cooling load on the refrigeration system.
j. If possible, avoid a location where the condenser and fresh air intakes will be laden with dust, dirt, soot,
smoke or other debris.
