Heat insulation for refrigerant pipes:

1Wrap the enclosed large-sized pipe cover around the gas pipe, making sure that the end of the pipe cover touches the side of the unit.

2Wrap the enclosed small-sized pipe cover around the liquid pipe, making sure that the end of the pipe cover touches the side of the unit.

3Secure both ends of each pipe cover with the enclosed bands. (Attach the bands 20 mm, 25/32 inch from the ends of the pipe cover.)

•After connecting the refrigerant piping to the indoor unit, be sure to test the pipe connections for gas leakage with nitrogen gas. (Check that there is no refrigerant leakage from the refrigerant piping to the indoor unit.)
