Figure 7- Charging the unit
NOTES
•
Use a charging hose with push rod when using the service port (5).
•
Make sure to keep stop valve open during operation.
•
Check for refrigerant gas leakage after tightening the cap.
WARNING
Do not purge the air with refrigerants. Use a vacuum pump to vacuum the installation.

LLP= length of liquid pipe (m)

Next perform a fine-tuning
For fine-tuning of the refrigerant charge, the compressor must operate.
•
If the liquid-line sight glass is showing seal after the rough charging (due to possible different conditions), add 10%
refrigerant charge weight.
•
If the liquid-line sight glass is showing some glass bubbles, the rough refrigerant charge is sufficient by fine-tuning the
additional 10% refrigerant charge weight.
•
If the liquid-line sight glass is showing flash gas, then charge until the additional 10% refrigerant charge weight. The unit
must have time to stabilize which means that this charging must be done in a smooth way.
WARNING Take care for contamination of the remote condenser in
order to avoid blocking of the system. It is
impossible for Daikin to control the contamination of the "foreign" condenser of the installer. The Daikin unit has a strict
contamination level.
WARNING
Use the liquid line check valve for charging refrigerant and make sure to charge liquid.
