SECTION II. OPERATOR'S PREVENTIVE MAINTENANCE CHECKS
AND SERVICES (PMCS)
2-3.
GENERAL.
Preventive Maintenance Checks and Services (PMCS) means systematic caring,
inspecting and servicing of equipment to keep it in good condition and to prevent breakdowns. As the water
heater's operator, your mission is to:
a.
Be sure to perform your PMCS each time you operate the water heater. Always do your PMCS in the
same order, so it gets to be a habit. Once you've had some practice, you'll quickly spot anything wrong.
b.
Do your BEFORE PMCS just before you operate the water heater. Pay attention to WARNINGs,
CAUTIONs, and NOTEs.
c.
Do your DURING PMCS while you operate the water heater. During operation means to monitor the
water heater and its related components while it is actually being operated. Pay attention to WARNINGs,
CAUTIONs, and NOTEs.
d.
Do your AFTER PMCS right after operating the water heater. Pay attention to WARNINGs,
CAUTIONs, and NOTEs.
e.
Do your WEEKLY PMCS once a week.
f.
Do your MONTHLY PMCS once a month.
g.
Use DA Form 2404 (Equipment Inspection and Maintenance Worksheet) to record any faults that you
discover before, during, and after operation, unless you can fix them. You DO NOT need to record faults that
you can fix.
h.
Be prepared to assist unit maintenance when they work on the heater. Perform any other services
when required by unit maintenance.
