If the problem is caused by lack of water flow rate the Integrity 10 will shut down to protect internal
parts from damage. Once chilled water has been restored the unit will automatically recommence
operation and the warning message screen will disappear.
If the problem is caused by the water temperature being too high the Integrity 10 will shut itself down
as previously mentioned in order to protect internal parts from damage. Again when the correct
temperature chilled water is restored the unit will recommence operation and the message screen
disappear.
Possible reasons for chilled water becoming too hot include but are not exclusive to:
Failed chiller unit.
More than one appliance connected to the chiller system returning water at temperature
greater than the chiller can cope with.
Integrity 10 connected in series with another piece of equipment returning chilled water at a
temperature above 35°C.
Low coolant flow rate which is insufficient to remove the heat from the heat exchangers (less
than 2.5/L per minute).
Note:
The chilled water flow rate must be continuous at minimum rate of 2.5 litres/min at 5
C.
The coolant system should be able to dissipate heat energy at 1100W with a coolant
temperature of 5
C. Running all 10 cell positions at -30
without a chilled water set at 5
C
supply may cause stress on the electrical components and result in a reduced performance
leading to shorted times between service requirements.

Error Message ‘Motor stalled’.
When the warning symbol appears in a single cell button and the cell button turns red, touch the cell
button to display the fault condition.
This illustration screen shot shows a stir motor fault with cell position number 2. The cell position may
still be used in heating / cooling mode but the cell will not stir. The cell will have to be replaced. See
Section 9.4 for cell replacement.
To return to the home screen and view the performance of other operational cells touch the back
button.
