For an HRS series thermo-chiller, what does it mean when alarm code “AL06” is generated and the thermo-chiller stops operating, and what can be done to remedy this?

This means that the resistance (pressure loss) of the piping, including the customer’s device, has exceeded the thermo-chiller pump capacity.
Check that there is no restriction in the piping, including the customer’s device.
If there is restriction, thicken the piping or relieve the circulating fluid flow rate with a bypass piping set.
Depending on the problem, however, consider requesting maintenance from a maintenance company.
We can recommend service providers if needed.
For details on resetting alarms, refer to section “7.3 Troubleshooting” in the HRS series operation manual, which can be found here.
