Pre-charging refrigerant
Step 1
Calculate additional refrigerant charge amount: R (kg)
Refrigerant overcharge happened, recover
refrigerant to reach R=Q
Step 2
• Open valves C and B to the liquid line
• Execute pre-charging amount: Q (kg)
Step 3a
• Close valves C and B
• Charging is finished
• Fill in the amount on the additional
refrigerant charge label
• Go to test run
Step 3b
Close valves C and B
R=Q R>QR<Q

Charging refrigerant
Step 5
Proceed with manual charge
Step 6
Activate field setting [2-20]=1
Unit will start manual refrigerant charging operation.
Step 7
• Open valve A
• Charge remaining amount of refrigerant P (kg)
R=Q+P
Step 8
• Close valve A
• Push BS3 to stop manual charging
• Charging is finished
• Fill in the amount on the additional refrigerant charge label
• Go to test run
Step 4
• Connect valve A to the refrigerant charge port (d)
• Open all outdoor unit stop valves
