• Apart from the CMY-Y202-F and CMY-Y302-F gas side, there are no
restrictions on the posture for attaching joints.
• Ensure that the branch pipes for the CMY-Y202-F and CMY-Y302-F
gas side are attached horizontally or facing upwards (see the dia-
gram below.)
Horizontal Facing upwards
(Facing downwards is not possible)
• There is no limitation on the joint mounting configuration.
• If the diameter of the refrigerant piping selected by the procedures
described on pages
