CONNECTING THE PIPING
OUTDOOR UNIT INSTALLATION
1. FLARE PROCESSING
(1) Cut the connection pipe with pipe cutters so
that the pipe is not deformed.
(2) Holding the pipe downward so that cuttings
cannot enter the pipe, remove the burrs.
(3) Remove the flare nut from the indoor unit pipe
and outdoor unit and assemble as shown in
(Table1) and insert the flare nut onto the pipe,
and flare with a flaring tool.
(4) Check if the flared part "L" (Fig.20)is spread
uniformly and that there are no cracks.
