[. . . ] 4 Fully close the gas stop valve when the pressure reading on the gauge drops to 0. * If too much refrigerant has been added to the air conditioner system, the pressure may not drop to 0. If this occurs, use a refrigerant collecting device to collect all of the refrigerant in the system, and then recharge the system with the correct amount of refrigerant after the indoor and outdoor units have been relocated. When commercially available copper pipes are used, wrap liquid and gas pipes with commercially available insulation materials (heat-resistant to 100 C or more, thickness of 12 mm or more). The indoor parts of the drain pipe should be wrapped with polyethylene foam insulation materials (specific gravity of 0. Apply thin layer of refrigerant oil to pipe and joint seating surface before tightening flare nut. Use leak detector or soapy water to check for gas leaks after connections are completed. 8 C IPipe size (Outdoor unit-Branch box) Pipe size (mm) Liquid Gas 9.

When usual pipe sealing is used, refer to Table 2 for flaring of R410A refrigerant pipes. 88 (5/8") A (mm) Flare tool for R410A Flare tool for R22 5-6) Remove the service panel D (three screws) and the front piping cover A (two screws) and rear piping cover B (two screws). The pipes can be protectively wrapped up to a diameter of 90 before or after connecting the pipes. Cut out the knockout in the pipe cover following the groove and wrap the pipes. Use putty or sealant to seal the pipe inlet around the pipes so that no gaps remain. (If the gaps are not closed, noise may be emitted or water and dust will enter the unit and breakdown may result. Conduct piping connection and valve operation accurately by following the figure below. Apply sealer along the insulator to prevent water entering the insulator covering the refrigerant pipe joints. After evacuation and refrigerant charge , ensure that the handle is fully open.
