3-5. INSTALLATION SITE PREPARATION

If the air conditioner is to be used on a shelter or system that is specifically designed to accept the air conditioner, see the

Technical Manual(s) for that shelter or system.

a. The following is a list of general guidelines for installation site preparation.

(1) A relatively level surface capable of bearing the weight of the air conditioner to insure proper condensate

drainage. The surface should be level to within 10 from front to back and side to side. See figures 3-1, 3-2, and 3-3 for

mounting dimensions.

(2) An unobstructed flow of air from outside the conditioned area to the ambient air inlet and discharge openings

on the rear of the condenser assembly.

(3) An unobstructed flow of air to and from inside the conditioned area to the return air inlet and the two supply air

outlets located on the front of the evaporator assembly.

NOTE

A return air filter is not provided as part of the air conditioner. It must be installed

in duct work connected to the return air inlet.

(4) An unobstructed flow of air from outside the conditioned area to the fresh air intake. See figure 3-1.

NOTE

The fresh air intake may be mounted on the left or right side of the evaporator

assembly by exchanging it with the fresh air cover plate.

(5) Access to all removable outside covers should be considered for servicing internal parts.

(6) A source of 208 volt, 3 phase, 400 hertz input power rated at 8 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.
