ESIE09-08A Precautions for New Refrigerant (R-410A)
Precautions for New Refrigerant (R-410A) 287

Differences

Change in pressure

Change in service port diameter
7. Charge hose for R-410A

Specifications

Working pressure 5.08 MPa (51.8 kg/cm
2
)

Rupture pressure 25.4 MPa (259 kg/cm
2
)

Available with and without hand-operate valve that prevents refrigerant from outflow.

Differences

Pressure proof hose

Change in service port diameter

Use of nylon coated material for HFC resistance
8. Charging cylinder

Specifications

Use weigher for refrigerant charge listed below to charge directly from refrigerant cylinder.

Differences

The cylinder can not be used for mixed refrigerant since mixing ratio is changed during charging.
When R-410A is charged in liquid state using charging cylinder, foaming phenomenon is generated
inside charging cylinder.
9. Weigher for refrigerant charge

Specifications

High accuracy
(Hose with ball valve)
Can not be used
