Section III. UNIT PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
4.10 GENERAl,. To insure that the air conditioner is ready for operation at all times, it must be inspected systematically
so that the defects may be discovered and corrected before the result is serious damage or failure. Defects discovered
during operation of the unit shall be noted for future corrections to be made as an operation has ceased. Stop operation
which would damage the equipment if operation were to continue. All deficiencies and shortcomings shall be recorded
together with the corrective action taken on DA Form 2404, Equipment Inspection and Maintenance Inspection
Worksheet, at the earliest opportunity. If your equipment fails to operate, troubleshoot with proper equipment. Report
any deficiencies using proper forms. See DA PAM 738-750.
Dry cleaning solvent (Item 16, Appendix E) used to clean parts is potentially dan-
gerous to personnel and property. Avoid repeated and prolonged skin contact. Do
not use near open flame or excessive heat. Flash point of solvent is 100 "F (38 "C).
Do not use compressed air for cleaning purposes, except where reduced to less than
30 psi (2.1 kg/cm2 ) and then only with effective chip guarding and personal protec-
tive equipment.
