Procedures for installing the branched pipes
Refer to the instructions that came with the branched pipe kit (separately sold) for details.
[1] Branches on the indoor-unit side
■
Joint
Restrictions for installing the joint described here only apply to CMY-Y202S-G2 and CMY-Y302S-G2 in the gas line.
CMY-Y202S-G2 and CMY-Y302S-G2 in the gas line must be installed horizontally (see figure above) or with the
branched pipes facing up.
If the size of the refrigerant pipe that is selected by following the instructions under 3-2. Piping Design does not match
the size of the joint, use a reducer to connect them. A reducer is included in the kit.
■
Header
No restrictions apply to the installation of the header.
If the size of the refrigerant pipe that is selected by following the instructions under 3-2. Piping Design does not match
the size of the header, cut the pipe to an appropriate size using a pipe cutter, or use a reducer to connect them.
If the number of header branches exceeds the number of pipes to be connected, cap the unused header branches.
Caps are included in the kit.
[2] Branches on the outdoor/heat source-unit side
Inclination of the branched pipes
The inclination of the branched pipes must be ±15° or less against the horizontal plane.
Excessive inclination of the branched pipes may damage the unit.
Minimum length of the straight section of the pipe before the branched pipes
Always use the pipes supplied in the branched pipe kit, and make sure the straight section of the pipe immediately
before it connects to the branched pipe is at least 500 mm. Failure to do so may damage the unit.
