Temperature scale indicates the relationship between pressure and temperature in gas
saturated state.
!
Differences
2
Change in pressure
2
Change in service port diameter
7. Charge hose for R410A
!
Specifications
2
Working pressure 5.08 MPa (51.8 kg/cm

)
2
Rupture pressure 25.4 MPa (259 kg/cm

Available with and without hand-operate valve that prevents refrigerant from outflow.
!
Differences
2
Pressure proof hose
2
Change in service port diameter
2
Use of nylon coated material for HFC resistance
8. Charging cylinder
!
Specifications
2
Use weigher for refrigerant charge listed below to charge directly from refrigerant cylinder.
!
Differences
2
The cylinder can not be used for mixed refrigerant since mixing ratio is changed during
charging.
When R410A is charged in liquid state using charging cylinder, foaming phenomenon is
generated inside charging cylinder.
(Hose with ball valve)
Can not be used
