damage. Clean out any inline strainers.
• Clean and repaint any areas that show signs of corro-
sion.
• Test vent piping of all relief valves for presence of
refrigerant to detect improperly sealed relief valves.
Replace any leaking relief valve.
• Inspect the condenser tubes for fouling; clean if nec-
essary. Refer to “Maintenance Procedures”.
• Check to make sure that the crank case heater is
working.
Scheduling Other Maintenance
• Use a nondestructive tube test to inspect the con-
denser and evaporator tubes at 3-year intervals.
Note: It may be desirable to perform tube tests on these
components at more frequent intervals, depend-
ing upon chiller application. This is especially true
of critical process equipment.
• Depending on chiller duty, contact a qualified service
organization to determine when to conduct a com-
plete examination of the unit to determine the condi-
tion of the compressor and internal components.
