(10)
Securely nail wooden crate closed, and wrap with steel handling strips.
(11)
Using the lifting method describe in paragraph 2-2c (1) or (2), place air conditioner on bed of carrier.
(12)
Securely block or tie the crated air conditioner on the carrier. If the carrier has a wooden floor, spike the
crated airconditioner to the carrier bed.
(13)
Store air conditioner in a room maintained at an even temperature and relatively low humidity. Cover
entire air conditioner with a tarpaulin when no suitable storage facility is available.
2-6. Reinstallation after Movement
a.
Short Distance. Reinstall air conditioner according to paragraph 2-4, after moving air conditioner a short
distance(para 2-5a).
b.
Long Distance. Reinstall airconditioner according to paragraphs 2-3 and 2-4, after moving air conditioner a long
distance (para 2-5b).

Section III. CONTROLS AND INSTRUMENTS
2-7. General
This section describes, locates, illustrates, and furnishes operator, crew, or organizational maintenance personnel
sufficient informational maintenance personnel sufficient information about various controls and instruments for proper
operation of the air conditioner.
2-8. Controls and Instruments
a.
Remote Control Box. The air conditioning switch and the continuously variable temperature control resistor (fig2-2)
are flush mounted on the front of the remote control box assembly. The switches function as follows:
.
(1) Air conditioning switch. The four position heat off vent cool, five deck air conditioning switch controls the air
conditioner mode of operation. When in the HEAT position the evaporator fan is place in operation and the heater
circuit is closed and controlled by the temperature control variable resistor. When in the OFF position all relays
are deenergized, and the air conditioner dows not condition the shelter air. When in the VENT position the air
conditioner recirculates the shelter air with the evaporator fan; freshair may be drawn into the shelter by turning the
fresh air contl handle, located in lower left hand front section of air conditioner, to OPEN position. When in the
COOL position the motor compressor circuit is closed, the evaporator and condenser fans are energized, and the
cooling system starts to function—cooling the shelter air.
(2) Temperature control. The continuously variable temperature control resistor controls the air conditioner return air
temperature. The temperature range on the cooling cycle is from 60 G to 90 F. The temperature range on the
heating cycle is from 60 F to 90 F.
b. Electrical Tray Panel. The system reset switch, elapsed time meter, 2bV DC supply ¾ amp fuse indicator light and
fuse holder, and the master circuit breaker (fig. 2-3) are flush mounted on the front panel of the electrical tray
assembly. The control and instrument functions as follows:
(1) System reset switch. This push button-type switch must be reset (depressed) in the event that the low ambient
temperature switch, or the compressor motor thermal overload contacts in the refrigerant circuit are tripped.
(2) Elapsed time meter. Culminate air conditioner operating is registered on the elapsed time meter. Total operating
time is read by locating the black bubble in the meter’s mercury column and noting the bubble height on the graduated
scale along side of the mercury column. The scale meter range is from 0 to 10,000 hours, each scale division being
equivalent to 100 hours operating time.
(3) Master circuit breaker. This circuit breaker controls the power supplied to the air conditioner through the power
input receptacle P101. This switch has ON (up) and OFF(down) positions.
