NOTE

•Make sure that the setting is appropriate so that liquid can be charged.

•A cylinder with siphon enables liquid to be charged without the cylinder turned upside down.

[Cylinder with siphon]

Gauge manifold

Outdoor unit

Refrigerant cylinder

[Cylinder without siphon]

Gauge manifold

Outdoor unit

Siphon pipe

Refrigerant cylinder

Electronic balance

NOTE

•Because R410A is HFC mixed refrigerant, charging with gas changes the charged refrigerant composition, causing the equipment characteristics to change.
