Cylinder with siphon

Cylinder without siphon

Siphon

Charge the refrigerant standing the cylinder upright.

Charge the refrigerant turning the cylinder upside down.

• If R-410A refrigerant is charged with gas, the composition of the charged refrigerant changes and the

characteristics of the equipment vary.

•During the measuring operation of refrigerant quantity added use electronic scales.

If cylinder doesn’t have syphon, upset it.
