c: The flow rate of the vacuum pump should range from 2 L/s to 4 L/s. The
absolute vacuum degree should be 60 Pa at most.
d: The pressure gauges and rubber hoses must be dedicated for R410A. The
measuring range of the pressure gauges must be at least 4.0 MPa, and the
rubber hoses must withstand a pressure of at least 4.5 MPa. Ensure that the
rubber hoses match the 1/4 inch needle valves inside the unit. If necessary,
prepare needle valve adapters. When charging refrigerant, you are advised to
use a safety valve to prevent refrigerant leakage during the removal of a rubber
hose, which may cause frostbite.
e: The nitrogen cylinder port should have a reducing valve, and the measuring
range should be at least 4.0 MPa.
