● If there is a low temperature component, open the low-pressure valves of
pressure gauge 1 and pressure gauge 2, and charge the remaining refrigerant
from the low-pressure needle valves in small
ow or intermittently.

Step 4 On the home screen, choose Running > Device Details > Compressor, and view
Discharge pressure and Suction pressure to determine whether they are within
normal ranges. Choose Running > Device Details > EEV and view EEV suction
superheat degree to determine whether it is within the normal range.
