OPERATING UNDER USUAL CONDITIONS

Section III.

2-5.

GENERAL.

a. The instructions in this section are published for the information and guidance of the

personnel responsible for the operation of the air conditioner.

The operator must know how to perform every operation of which the air conditioner is

capable. This section gives instructions on starting and stopping the air conditioner, and detailed

operating instructions. Since nearly every condition presents a different problem, the operator

may have to vary the given procedure to fit the condition.

UNLOADING EQUIPMENT.

2-6.

The total weight of the air conditioner is 290 pounds (132 kg.). Use a hand truck or fork-

lift of at least 500 pounds capacity to unload the unit. Keep unit upright during the unloading

operation.

2-7.

UNPACKING EQUIPMENT.

Move the unit as near to the site of installation as possible. Remove crating hardware and

metal straps being careful not to damage the unit with the tools used for uncrating.

2-8.

INSPECTING AND SERVICING EQUIPMENT.

a. Inspection. Inspect the entire air conditioner for signs of damage, missing or loose

hardware, an any defects that may have been incurred during shipment. Report all damage and

defects to organizational maintenance.

b. Servicing. Perform the daily preventative maintenance services listed in paragraph

2-4. Be sure all hardware is securely in place.

INSTALLATION.

2-9.

General. The air conditioner is shipped assembled and ready for operation. It contains

a full charge of refrigerant and compressor oil. Install the unit on a firm, level surface to allow

proper condensate drainage. Place it so that the control panel and condenser and evaporator

louvers are accessible to the operator and to maintenance personnel. Be sure there are no

obstructions in front of any air intake or discharge louvers or other openings that may cause

insufficient flow of air in to or out of the air conditioner. If the unit is van mounted, report

any such obstructions to organizational maintenance.

b. Lifting. Check for broken or deformed lifting ring attachment and hardware before

lifting air conditioner. Lift with crane or forklift truck.

Use lifting harness with 4-leg spreader bar. Each leg must

be capable of withstanding a concentrated load of more than

500 pounds. If spreader bar cannot be used, the angle bet-

ween the harness legs and the top of the air conditioner must

not be less than 45-degrees.

c. Mounting. Base mounting hole dimensions are shown on figure 2-3. The resilient mount

parts shown in figure 2-4 are shipped with the air conditioner.

For safe operation connect a No. 10 AWG (min.) ground

wire between the air conditioner ground connection and

an earth ground, as shown in figure 2-5.
