Additional Refrigerant Charge - Mitsubishi Electric City Multi PUHY-P200YNW-A Installation Manual

9-9. Additional refrigerant charge

Charge refrigerant in a liquid state.
- Charging refrigerant in the gaseous state will change the composition of the refrigerant and lead
to a performance drop.
Do not use a charging cylinder when charging refrigerant.
- The use of a charging cylinder may change the composition of the refrigerant and lead to a
performance drop.
The table below summarizes the factory-charged amount of refrigerant, the maximum amount of refrigerant to be
added on site, and the maximum total amount of refrigerant in the system.
