CHAPTER 4
UNIT MAINTENANCE INSTRUCTIONS
Section I. SERVICE UPON RECEIPT OF MATERIAL
4-1. Inspecting and Servicing the Equipment
After removal from the shipping container, inspect the outside of the air conditioner for damage. There should be no
dents, gauges, deformation or scuffed paint. The air conditioner is shipped ready for operation. No servicing is required.
4-2. Installation.
a. Location. The air conditioner models F60T-2, F60T-2A, and CV-60-5/6-08 are designed to be mounted in an out-
side wall of the enclosure that it is to cool or heat, with the front surface approximately flush with the inside wall. The
supporting structure may be made of wood, structural steel or concrete, resting or below-grade footings if necessary to
prevent settling. For greatest efficiency, the unit should be located on the north wall of the enclosure, or in a shaded
area. The area behind the unit must be kept clear of obstructions to permit unrestricted airflow.
NOTE
The area behind the condenser fan should be kept free of shrubbery for
at least 10 feet. The hot air discharged by the condenser fan will kill
most plant life.
b. Mounting. The air conditioner can be bolted to the floor or supporting surface by 7/16-14 bolts, threaded through
holes in the base plate. (See Figure 2-2.) Adequate clearance should be left between the top of the unit and the wall to
permit removal of the top for service and maintenance. The space can be filled with a removable strip of any satisfac-
tory material such as sheet metal or plywood.
c. Transit. If a unit is to be transported while mounted in a shelter, it is necessary to secure the top of the unit to the
shelter for stability. This is accomplished using the flush door rings located on each side of the unit close to the top.
d. Drainage. Provisions for drainage of condensate water from the evaporator coil must be made. Pipe plugs (1/2-
14 NPT) are located in each side of the bottom panel so that standard plumbing fittings can be installed in the most con-
venient location(s) for drainage. The condensate can be conducted to a storm sewer, dry sump or other facility by means
of a hose or rigid plumbing.
e. Service. A source of 208-Volt, 50/60 Hertz, 3 phase (4-wire) electric power must be supplied to operate the air
conditioner. The power input receptacle is located on the left side of the unit, about six inches above the drain plug. If
this location is unsuitable, alternate locations are provided. The receptacle can be removed from its normal location and
installed in the lower front panel beside the control panel, in the rear panel at the 8 o'clock position beside the condenser
fan, in the lower rear quarter of the right-hand side, or in a receptacle behind the left-hand return air grille. A ground wire
should be attached to the grounding stud at 8:30 position beside the condenser fan. The other end of the ground wire
must be connected to a copper rod driven at least 18 inches (45.7 CM) into the earth.
