• Signal cable (to inverter) is connected to the chiller unit.
• Chiller fluid level should be MAX. If not, fill with fresh water.
• If water temperature is too low, wait for the temperature to attain proper value ( 19
o
C / 66
o
F ).
The chiller is equipped with an internal, automatic heater.
First time startup
• Check that the supply matches the rated voltage.
• Check that the electrical connection has been made correctly.
12.12.3. Error Conditions
One common error signal is routed from the Chiller system to the
inverter and further into the control system.
The following error conditions are monitored:
• Temperature out of range (high and low)
• Water level too low
• Liquid flow too low (less than 0.8 l/min). The signal is 1 minute
delayed, to be able to fill water hoses at startup..
During normal operation, the cooling medium temperature is displayed.
If any chiller failure occurs:
• Alarm signal is generated.
• Chiller will stop.
• Look at the chiller display to see the real reason for the problem:
Code Description
AL Water level or water flow too low. Check for correct water level in the Water
Level Indicator on Chiller front.
H1 (Chiller 2016) Temperature of cooling medium too high, > 35
o
C / 95

F
H1 (Chiller 2020) Temperature of cooling medium too high, > 45

L1 Temperature of cooling medium too low, < 19

C / 66
o
F
Continue after error situation
• Find root cause for the error situation and fix it. Flow too low is normally caused by a squeezed
water hose.
• Switch chiller unit OFF and ON again.
