AIR CONDITIONER, HORIZONTAL, COMPACT

(NSN 4120-01-502-1319)

SERVICE UPON RECEIPT

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 of the

conditioned area. Minimum requirements for all installation includes:

A level surface capable of bearing the weight of the air conditioner of which to set the base. To ensure proper

condensate drainage, level from side to side and front to back. An unobstructed flow of air from outside the

conditioned area to the intake and discharge of the condenser fan (back face of air conditioner). Refer to the

illustrations in this work package for mounting dimensions.

An unobstructed flow of air from inside the conditioned area to the intake and discharge openings (front face of air

conditioner).

An unobstructed flow of air from the outside conditioned area to the fresh air intake. (Back face of air conditioner.)

Access to the front and back of the air conditioner for routine operation, servicing, and necessary maintenance

actions.

Sufficient access to allow for the removal of the front and rear top panels is necessary.

A source of 208 volt, 3 phase, 400 hertz input power rated at 10.0 amps for the F9000H-4SPFI. 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. Provisions should be made to insure that power is not disconnected during normal

operation and that the disconnect switch is not used to turn off the air conditioner for normal shutdown.

Make sure no sources of dangerous fumes are near the fresh air intake.

If possible, avoid a location where the condenser and fresh air intake will be laden with dust, soot dirt, smoke, or

other debris.

SERVICE UPON RECEIPT OF MATERIAL

UNLOADING

The air conditioner is packaged in a container designed for shipment and handling with the cabinet in the upright position.

The base of the container is constructed as a shipping pallet.

To unload the air conditioner:

1. Remove all blocking and tie downs that may have been used to secure the container to the carrier.

2. Use a forklift, or other suitable material handling equipment, to remove the packaged unit from the carrier.

CAUTION

Use care in handling to avoid damage to the air conditioner. If an overhead lifting device

is used, use an appropriate sling so the weight of the unit is borne by the base of the

shipping container.

To unpack the Air Conditioner:

1. Prior to unpacking, move the air conditioner into the area where it will be installed.

NOTE

The shipping container may be retained for reuse for mobility purposes, if frequent

relocation of the air conditioner is expected.
