OPERATING LOG
The use of an operating log, as included in this manual, permits thorough analysis of the operation of a refrigeration system by
those responsible for its maintenance and servicing. Continual recording of gauge pressures, tem per a 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.
