outlined in paragraph 4–3.
OF EQUIPMENT TO PREVENT ENEMY USE
When capture or abandonment of the air condi-
tioner to an enemy is imminent, the responsible
unit. commander must make the decision either to
destroy the equipment or to render it inoperative.
Based on this decision, orders are issued which
cover the desired extent of destruction. Whatever
method of demolition is employed, it is essential
to destroy the same vital parts of all air condi-
tioners and all corresponding repair parts.
4-6. Demolition to Render Equipment
Inoperative
a. Mechanical Means.
Use sledge hammers,
crowbars, picks, axes. or any other heavy tools
which may be available to destroy the following:
(1) Compressor and compressor motor.
(2) Condenser assembly.
(3) Evaporator assembly.
(4) Condenser and evaporator fans.
Note. The procedures in (1) thru (4) are mini-
mum requirements for this method.
(5) Remove control panel and junction box.
b. Misuse. Perform the following steps to ren-
der the air conditioner inoperative.
(1) Remove the air conditioning filter, and
drop nuts, bolts, or small metallic objects into the
evaporator fan housing.
(2) Pull circuit breaker up and plug in the
main power cable.
N o t e . The procedures in (1) and (2) above are
minimum requirements for this method.
4-7. Demolition by Explosives or Weapons
Fire
a. Explosives. Place as many of the charges as
the situation permits, and detonate them simulta-
neously with a detonating cord and suitable de-
tonator.
(1) One ½ - pound charge inside the junc
tion box.
(2) One ½-pound
fan.
(3) One ½-pound
ser.
(4) One ½-pound
orator assembly.

charge next to the evap-
Note. The charges are a minimum requirement for
this method.
b. Weapons Fire. Fire on the air conditioner
with the heaviest practicable weapons available.
4-8. Other Demolition Methods
a. Scattering and Concealment. Remove all eas-
ily accessible parts, such as the remote control
box and wiring harness, and scatter them
through dense foliage, bury them, or throw them
in a body of water.
b. Burning. Pack rags, clothing, or c a n v a s
under and around the unit and inside the con-
denser and evaporator frames. Saturate t h i s
packing with gasoline, oil, or diesel fuel, and ig-
nite.
c. Submersion. Totally submerge the unit in a
body of water to provide water damage and con-
cealment. Salt water will do greater damage to
metal parts than fresh water.
4-9. Training
All operators should receive thorough training in
the destruction of the air conditioner. Refer to
FM 5-25. Simulated destruction, using all of the
methods listed above, should be included in the
operator training program. It must be empha-
sized in training that demolition operations are
usually necessitated by critical situations when
time available for carrying out destruction is lim-
ited. For this reason, it is necessary that opera-
tors be thoroughly familiar with all methods of
destruction of equipment, and be able to carry out
demolition instructions without reference to this
or any other manual.
