APPENDIX C — MAINTENANCE SUMMARY
AND LOG SHEETS
19MV Maintenance Interval Requirements
NOTE: Equipment failures caused by lack of adherence to the Mainte-
nance Interval Requirements are not covered under warranty.
WEEKLY
COMPRESSOR None. CONTROLS Review PIC6 Alarm/Alert History.
EVAPORATOR None. VFD None.
CONDENSER None. UPS
PIC6 automatically performs UPS Discharge Level test of
the battery. Alert 117 will be active should the test fail.
Should Alert 117 become active the battery will need to be
replaced within 2 weeks. Upon replacement, the new bat-
tery must be acknowledged in the UPS Config menu (Bat-
tery Replacement Done = Yes). If no action is taken UPS
Battery Replacement Alarm 481 will be active, resulting in
chiller shutdown.
MONTHLY
COMPRESSOR None. CONTROLS None.
FIRST YEAR
COMPRESSOR Replace motor coolant line filter drier. EXVS Clean EXV strainers.
ANNUALLY
COMPRESSOR
Change motor cooling line filter drier. Leak test. Replace
desiccant packet inside MBC cavity.
CONTROLS
Perform general cleaning. Tighten connections. Check
pressure transducers. Confirm accuracy of thermistors.
Complete a MBC clearance check. Record MBC drop
counts against the limit.
EVAPORATOR
Inspect and clean evaporator tubes. Confirm there is no
foreign debris in the tubes or waterboxes from the water
system. Inspect all pressure relief devices. Leak test. Verify
water pressure differential. Inspect water pumps. Send
refrigerant sample out for analysis. Replace liquid strainer
in inhibitor reclaim line (closest to evaporator inlet).
VFD
Perform general cleaning. Tighten connections. Perform
visual inspection of the capacitors located on the DC bus
and inductors. Check cooling fan operation. Replace or
clean air filter.
CONDENSER
Inspect and clean condenser tubes. Leak test. Verify
water pressure differential. Inspect water pumps and
cooling tower.
POWER
PANEL
Perform general cleaning of air filter located in the door of
the high voltage section. Filter mesh is made of washable
aluminum. Verify that fan is operating. Fan exit is located on
the back of the high voltage section. Fan will operate when
enclosure temperature exceeds 70°F (21°C). Replace the
motor coolant line filter drier.
EVERY 3 TO 5 YEARS
COMPRESSOR None. CONTROLS Replace UPS battery.
EVAPORATOR Perform eddy current test. VFD None.
CONDENSER
Inspect EXVs and clean or replace strainers. Perform
eddy current test.
SEASONAL SHUTDOWN
COMPRESSOR None. CONTROLS None.
EVAPORATOR
Isolate and drain waterbox. Remove waterbox cover
from one end. Use compressed air to clear tubes.
VFD None.
CONDENSER
Isolate and drain waterbox. Remove waterbox cover
from one end. Use compressed air to clear tubes.
