a: The specifications of thread sealant/sealing tape are as follows:

• Applicable to all pipe materials
• Anaerobic metal pipe thread sealant with PTEF as the padding
• Maximum gap: 0.5 mm
• Pressure resistance: above 1.6 MPa
• Compliant with industry standards

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.

f: Dry nitrogen.
