that the front of the cabinet is inside the room or enclosure and back outside.
installations may be made with the entire cabinet either inside or outside the conditioned area.
Refer to MIL-HDBK-116, Environmental Control of Small shelters, for additional general
information. The following are minimum requirements for all installations:
(1) 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.
(2) An unobstructed flow of air from outside the conditioned area to the inlet and
two outlets of the condenser fans.
(3) An obstructed flow of air from inside the conditioned area to the conditioned air
intake and discharge.
(4) An obstructed flow of air from outside the conditioned area to the fresh air
damper intake and/or NBC filter intake, if installed.
(5) Access to the front and back of the cabinet for routine operation and servicing and
for necessary maintenance actions.
(6) Access to the top of the cabinet for removal of the top panel and sufficient
headroom to allow maintenance actions and internal component removal and
installation through the top panel opening if possible.
(7) A source of 208 VAC, 3 phase, 400 hertz input power rated at 48 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 shut-down.
