Section II. CONDENSOR/EVAPORATOR REPAIRS

3-4. General. Most copper tubing lines within condensor or evaporator coils are 3/8" diameter and can be brazed to

repair minor damage. Other lines which may be larger can also be repaired though replacement line may not be readily

available. This section concentrates on major line damage repair techniques offered through splicing, bypassing, or

replacement of useful line.

3-5. By-Passing Damaged Line. In some instances, damage to a loop within a condenser or evaporator may be

impossible to repair. This procedure allows by-pass of damaged lines where access to the end of a condensor or

evaporator is feasible.

a. General Information

(1) Limitations.

Degraded cooling output.

(2)

Personnel/Time required.

1 Soldier/8.0 hours.

(3)Materials/Tools.

Tool Kit, Service Refrigeration Unit (Appendix B, Item 12)

Copper Tubing Identical Size to that Damaged (Appendix C)

b. Procedural Steps:

WARNING

High Voltage exists in this equipment. DEATH ON CONTACT may result if personnel fail

to observe safety precautions. Turning the switch on the ECU, to the OFF position, does

not meet the requirements of disconnecting power from the ECU.

(1) Disconnect electrical power source from ECU.

(2) Gain access to end of damaged condensor or evaporator.

(3) Remove loop at end of damaged line and next loop in sequence.

(4) Measure replacement tubing and cut to ensure tight bends at each end of replacement loop.
