Inadequate temperature control
Verify the setpoint.
If the chiller is over-cooling, recycle the power.
Make sure the condenser/air filter is free of dust and debris.
Check the fluid concentration, see Section 3.
Ensure chiller installation complies with site requirements, see Section 3.
Make sure supply voltage matches chiller nameplate rating ±10%.
For ThermoFlex900 - 5000 global voltage chillers ensure the
chiller is
properly configured, see Appendix B.
If the temperature continues to rise, make sure your application's heat
load does not exceed the rated specifications.
Check for high thermal gradients (e.g., the application load is being
turned on and off or rapidly changing).
Verify/adjust controller PID values, see next page.
Chiller vibration
The optional pressure relief valve setting may be the cause. Change the
pressure setting ± 5 psi to eliminate the vibration.
