Overview of system operation check procedure
Step-1
: Connect Service Tool PC to the VRF VR-II system.
Do scaning of refrigerant system which should be commissioned.
Step-2
: Compare the number of installed units (OU, RB Group and IU) with the System List data obtained from the Service Tool.
Step-3
: Operate all Indoor Units under Test Mode Cooling (Select Test mode either cool or heat based on ambient temperature.).
Step-3-1: During operation, check the RB unit SV status and IU thermistor value
Step-3-2: After 1-hour operation, check the Refrigerant System
Step-4
: After 1-hour Test run operation (excluding special operation),
Step-4-1: Switching the operation mode of IU, in order of RB group number, from cool to heat.
- Check the RB unit SV status and IU thermistor value
Step-4-2: When all IUs run under heating, continue operation minimum 15min. And check the Refrigerant system
