Table 22. Recommended maintenance
Daily
Check the chiller's evaporator and
condenser pressures, oil tank
pressure, differential oil pressure,
and discharge oil pressure.
Compare the readings with the
values provided in the preceding
table.
Check the oil level in the chiller oil
sump using the two sight glasses
provided in the oil sump head.
When the unit is operating, the oil
level should be visible in the lower
sight glass.
Complete logs on a daily basis.

Every 3 months
Clean all water strainers in the
water piping system.
Every 6 months
Lubricate the vane control linkage
bearings, ball joints, and pivot
points.
Lubricate vane operator tang O-
rings.
Operate the tang operators
manually and check for any
abnormalities.
Lubricate the oil filter shutoff valve
O-rings.
Drain contents of the rupture disk
and purge discharge vent-line
drip-leg into an evacuated waste
container. Do this more often if the
purge is operated excessively.
Apply oil to any exposed metal
parts to prevent rust.

Annually (a) (b)
Shut down the chiller once each year to check the
items listed on the "CVHE, CVHF, and CVHG
CenTraVac™ Chiller Annual Inspection List," p. D–
1 (refer to "Forms and Check Sheets," p.
For R-123 chillers, perform the annual
maintenance procedures referred to in Operation
and Maintenance Guide: EarthWise Purge System
with Tracer AdaptiView Control for Water-Cooled
CenTraVac Chillers with R-123 Refrigerant
(PRGD-SVX01*-EN). For R-514A chillers, perform
the annual maintenance procedures referred to in
Operation and Maintenance Guide: Purge System
with Tracer AdaptiView Control for Water-Cooled
CenTraVac Chillers with R-514A Refrigerant
(PRGE-SVX001*-EN).
Use an ice water bath to verify the accuracy of the
evaporator refrigerant temperature sensor
(4R10). If the sensor is exposed to temperature
extremes outside its normal operating range (0°F
to 90°F [-17.8°C to 32.2°C]), check its accuracy
at six-month intervals.
Inspect the condenser tubes for fouling; clean if
necessary.
Inspect and clean the ifm efector® flow detection
sensors. Use Scotch-Brite® or other non-abrasive
material to clean scale; do NOT use steel wool,
which could cause the probe to rust.
