a. Pressure gauge and leather hose: dedicated for R410A. The measuring range
of the pressure gauges must be at least 4.0 MPa, and the leather hoses must
withstand a pressure of at least 4.5 MPa. Ensure that the leather pipes match
the 1/4 inch needle valves inside the unit. If necessary, prepare needle valve
adapters.
b. Dry nitrogen.
c. Nitrogen reducing valve: A reducing valve must be installed on the head of
the nitrogen cylinder, and the reducing valve range must be at least 4.0 MPa.
d. Vacuum pump airflow: 2–4 L/s; absolute vacuum: ≤ 60 Pa.
