Periodic Maintenance
• Check the refrigerant charge and oil level. Refer to Paragraphs "Weekly
Maintenance" on Page 133 and "Oil Separator Level Check" on Page 139.
Routine changing of oil is not required.
• Have a qualified laboratory perform a compressor oil analysis to deter-
mine system moisture content and acid level. This analysis is a valuable
diagnostic tool.
• Check the pressure drop across the oil filter. See Paragraph "Oil Filter
Change" on Page 140.
• Contact a qualified service organization to leak test the chiller, to check
operating and safety controls, and to inspect electrical components for
deficiencies.
• Inspect all piping components for leakage and damage. Clean out any
inline strainers.
• Clean and repaint any areas that show signs of corrosion.
