Section Ill. PREVENTIVE MAINTENANCE CHECKS AND SERVICES

To insure that the air conditioner is ready for op-
eration at all times, it must be inspected system-
atically so that defects may be discovered and cor-
rected before they result in serious damage or
failure. The necessary preventive maintenance
checks and services to be performed are listed
and described in paragraph 3-5. The item num-
bers indicate the sequence of minimum inspection
requirements. Defects discovered during opera-
tion of the unit will be noted for future correc-
tion, to be made as soon as operation has ceased.
Stop operation immediately if a deficiency is
noted which would damage the equipment if op-
eration is continued. All deficiencies and the cor-
rective action taken will be recorded on DA Form
2404 (Equipment Inspection and Maintenance
Worksheet ) at the earliest possible opportunity.
