Calculate additional refrigerant charge amount: R [kg]
Step 1
• Close valve A
• Open valve B to the liquid line
• Execute pre-charging amount: Q (kg)
Step 2 + 3
Close valve B
Step 4a
• Connect valve A to the refrigerant charge port (d)
• Open all outdoor unit stop valves
Step 5
Activate field setting [2-20]=1
Unit will start manual refrigerant charging operation.
Step 6
• Open valve A
• Charge remaining amount of refrigerant P (kg)
R=Q+P
Step 7
• 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 8
• Close valve 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
Refrigerant overcharge happened, recover refrigerant to
reach Q=R
Step 4c
Q<R Q=R Q>R

16.5 To charge refrigerant
To speed up the refrigerant charging process, it is in case of larger
systems recommended to first pre-charge a portion of refrigerant
through the liquid line before proceeding with the manual charging. It
can be skipped, but charging will take longer then.
Pre-charging refrigerant
1 Calculate the additional amount of refrigerant to be added using
the formula mentioned in "16.3 To determine the additional
refrigerant amount"[432].
Note: The first 10 kg of additional refrigerant can be pre-charged
without outdoor unit operation.
Note: Pre-charging can be done without compressor operation
Prerequisite: Make sure that all outdoor unit stop valves and
manifold valve A are closed. Disconnect the manifold from the gas
lines.
2 Connect the manifold valve B to the service port of the liquid
stop valve.
3 Pre‑charge refrigerant until the determined additional refrigerant
amount is reached or pre‑charging is not possible anymore.
