14.4.4 To charge refrigerant: Flow chart
For more information, see "14.4.5To charge refrigerant"[426].
Pre-charging refrigerant
Step 1
Calculate additional refrigerant charge amount: R (kg)
Refrigerant overcharge happened, recover
refrigerant to reach R=Q
Step 2+3
• Open valves C, D and B to the liquid and equalising line
• Charge the equalising line to maximally 0.05 MPa, then close valve C and
disconnect its connection to the manifold. Continue pre-charging through
the liquid line only
• Execute pre-charging amount: Q (kg)
Step 4a
• Close valves D and B
• Charging is finished
• Fill in the amount on the additional
refrigerant charge label
• Input the additional refrigerant amount via
setting [2-14]
• Go to test run
Step 4b
Close valves D and B

Charging refrigerant
Step 6
Proceed with automatic or manual charge
Step 6b
Activate field setting [2-20]=1
Unit will start manual refrigerant charging operation.
Step 6a
• Push 1x BS2: "888"
• Push BS2 for more than 5 seconds "t01" pressure equalisation
• Open valve A
• Charge remaining amount of refrigerant P (kg)
R=Q+P
Depending on ambient conditions, the unit will decide to perform autocharge
operation in heating or cooling mode.
• Close valve A
• Push BS3 to stop manual charging
• Charging is finished
• Fill in the amount on the additional refrigerant charge label
• Input the additional refrigerant amount via setting [2-14]
• Go to test run
Step 5
• Connect valve A to the refrigerant charge port (d)
• Open all outdoor unit stop valves
