Preventive Maintenance Checks and Services (PMCS) are essential to the efficient operation of the refrigeration unit and
to prevent possible damage that might occur through neglect or failure to observe warning symptoms in a timely manner.
Checks and services performed by operators are limited to those functions which can be done from the outside of the
cabinet or behind access doors. The Preventive Maintenance Checks and Services Table 2-1 lists the inspections and
care of the refrigeration unit required to keep it in good operating condition.
a.
Warnings and Cautions. Always observe the WARNINGs and CAUTIONs appearing in your PMCS Table.
Warnings and cautions appear before applicable procedures. You must observe these WARNINGs and CAUTIONs to
prevent serious injury to yourself and others or prevent your equipment from being damaged.
