MAINTENANCE SCHEDULE
OPERATING LOG
The use of an operating log as included in this manual (see Table of Contents) permits thorough analysis of the operation of a
refrigeration system by those responsible for its maintenance and servicing. Continual recording of gauge pressures, tempera-
tures, and other pertinent information, enables the observer and serviceman to be constantly familiar with the operation of the
system and to recognize immediately any deviations from normal operating conditions. It is recommended that readings be taken
at least every four hours.
This schedule should be followed to ensure trouble-free operation of the compressor unit.
