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. The following is a list of general

guidelines for installation site preparation.

A relatively level surface capable of bearing the weight of the air conditioner to ensure proper

condensate drainage. The surface should be level to within 10Ε from front to back and side to

side. See the following three figures for mounting dimensions.

An unobstructed flow of air from outside the conditioned area to the ambient air inlet and

discharge openings of the rear of the condenser assembly.

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

ductwork connected to the return air inlet.

An unobstructed flow of air from outside the conditioned area to the fresh air intake.

NOTE

The fresh air intake (not supplied) may be mounted on the left or right side of the

evaporator assembly by exchanging it with either fresh air cover plate.

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

A source of 208 volt, 3 phase, 400 hertz input power rated at 28 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 ensure

that power is not disconnected during normal operation and that the disconnect is not used to turn

off the air conditioner for normal shutdown.

WARNING

Check that no source of dangerous or objectionable fumes is near the fresh air intake.
