Tool name
Pressure is huge and cannot be measured with a
conventional (R22) gauge. To prevent erroneous mixing
of other refrigerants, the diameter of each port has been
Gauge manifold
changed.
It is recommended to use a gauge manifold with a high
pressure display range –0.1 to 5.3 MPa and a low pressure
display range –0.1 to 3.8 MPa.
To increase pressure resistance, the hose material and base
Charging hose
size were changed.
A conventional (R22) vacuum pump can be used by installing
a vacuum pump adapter.
Vacuum pump
Be sure that the pump oil does not backflow into the system.
Use one capable for vacuum suction of –100.7 kPa (5 Torr,
–755 mmHg).
Gas leakage detector
Special gas leakage detector for HFC refrigerant R410A.
2.3. Accessories
For installation purposes, be sure to use the parts supplied by the manufacturer or
other prescribed parts.
