VRV IV+ heat pump for high ambient temperatures

4P561157-1A – 2020.10

18.4.4 To charge refrigerant: Flow chart

For more information, see "To charge refrigerant"[492].

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
