5-32. PRESERVATION PROCEDURES.
Ensure that all refrigerant has been recovered from the system and open refrigerant lines are capped securely to prevent
moisture from entering the system.
Administrative storage is short term storage (1 to 45 days). It covers storage of equipment which can be readied for
mission performance within 24 hours.
Intermediate storage is 46 to 180 days and requires no special handling other than protection from damage and the
elements.
Long term storage and flyable storage are for indefinite periods of time and require special steps to prepare the
equipment. See paragraphs 5-33.a through 5-33.c below for preparing each component of the air conditioner for long
term or flyable storage.
5-33. PACKING.
a. Control Module Assembly Preservation . Place protective caps over the electrical connectors. (If original
protective caps are not available, use a substitute that will prevent moisture, dirt or other foreign matter from entering the
electrical connectors). Wrap the unit with two layers of heavy plastic material or barrier paper. Using banding material,
strap the Control Module Assembly to the same wooden pallet or suitable skid base with either the Condenser Assembly
b. Condenser Assembly Preservation. Recover the refrigerant and disconnect refrigerant lines. Immediately place
protective caps over the refrigerant fittings and electrical connectors. (If original protective caps are not available, use a
substitute that will prevent moisture, dirt or other foreign matter from entering the vacuum of the refrigerant system or
electrical connectors). Evacuate the condenser assembly. Wrap the unit with two layers of heavy plastic material or
barrier paper. Using banding material, strap the Condenser to a wooden pallet or other skid base suitable for forklift
c. Evaporator Assembly Preservation. Recover the refrigerant and disconnect refrigerant lines. Immediately place
protective caps over the refrigerant fittings and electrical connectors. (If original protective caps are not available, use a
substitute that will prevent moisture, dirt or other foreign matter from entering the vacuum of the refrigerant system or
electrical connectors). Evacuate the Evaporator Assembly. Wrap the unit with two layers of heavy plastic material or
barrier paper. Using banding material, strap the Evaporator Assembly to a wooden pallet or other skid base suitable for
