NOTICE
To avoid compressor breakdown, do NOT charge more than the specified amount of
refrigerant.
Prerequisite: Before charging refrigerant, make sure the refrigerant piping is
connected and checked (leak test and vacuum drying).
1 Connect the refrigerant cylinder to the service port.
2 Charge the additional refrigerant amount.
3 Open the gas stop valve.

NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO
Formula to calculate the quantity in CO
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label.
2 Fix the label on the inside of the outdoor unit near the gas and liquid stop
valves.
INFORMATION
Applicable ONLY for combination with indoor units CVXM-A9, FVXM-A9.
All field made refrigerant joints must be tested for tightness.
No leak shall be detected with a test method that has a sensitivity of 5 grams
refrigerant per year or better, at a pressure of at least 0.25 times the maximum
working pressure (see "PS High" on the unit name plate).
