Keep the distance between the chiller and the instrument being cooled as
short as possible.
Ensure tubing is straight and without bends. If diameter reductions are
required, make them at the inlet and outlet of your application, not at the
chiller.
Chiller will not circulate process fluid
Check the reservoir level. Fill, if necessary.
Ensure the reservoir bag filter is not clogged.
Check the application for restrictions in the cooling lines.
Chiller requires >3 PSIG application pressure drop. If a bypass valve has
been installed, a restriction may need to be added to the bypass line.
The pump motor overloaded. The pump's internal overtemperature
overcurrent device will shut off the pump causing the flow to stop. This can
be caused by low fluid, debris in system, operating
temperature condition or excessively confined space. Allow time for the
motor to cool down.
Make sure supply voltage matches the
Inadequate temperature control
Adding fluid that has a temperature differential with the fluid already in the
reservoir will temporarily affect temperature stability performance.
Verify the setpoint.
For high-temperature chillers check the heater's
high temperature safety. Remove the two small
black plastic covers on the rear of the
and press on each of the black stems. If the
safety activated you should hear a "click. " If it
activates again contact us.
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 your chiller's installation complies with the site requirements listed in
Section 3.
Make sure supply voltage matches the chiller's nameplate rating ±10%.
For ThermoFlex900 - 5000 Global Voltage chillers ensure it 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.
