Check during start
After the above procedure, start the chiller to check whether everything works normally.
If there is any issue, immediately stop the product and follow the "Troubleshooting" process.
Refer to the Appendix for the criteria of each detail.
Follow the below procedure for checkpoints when starting the chiller.
- Check the rotating direction of the condenser fan motor. Place newspaper or tissue to check
whether the air flow is normal around the motor.
- Check whether the cold water outlet temperature is the same as the setting.
- Through HMI device, check whether all sensors show effective values. Temperature sensor
detects the compressor discharge temperature, compressor suction temperature, condenser
outlet temperature and cold water inlet/outlet temperature.
- Check whether the operating current, operating noise and vibration is the same as the product
specification.
Stop
After completing to check based on the above procedure, stop the product.
After the above procedure, start the chiller to check whether everything works normally.
If there is any issue, immediately stop the product and follow the "Troubleshooting" process.

Load operation and operation adjustment
After starting and stopping the product, check the product function by operating the load and
adjusting the operation.
Adjust the cold water outlet temperature setting to adjust the load to check the product while
changing the operating condition.
Prepare operation data
Always record the operating condition when operating the chiller to check whether it is operating
normally compared to the specification.
Refer to 'the standard operation record' page of Appendix.
Analyze water quality of cold water
Analyze the water quality during the test run and secure the data.
Compare the water quality analysis result after a certain period of time (monthly check is recom-
mended) against that of test run to decide the period to change the water.
