1. Designing CMY-R160-J1 to a PURY/PQRY system
The maximum down-stream Indoor capacity for 1 port of BC
controller is P54. When the down-stream Indoor capacity is
above P54, Joint kit CMY-R160-J1 is needed to combined 2
ports of BC controller to enlarge the capacity, like Group 2 and
3 in Fig. 1.
Maximum 3 Indoor units are allowed to connect to 1 port of BC
controller or 2 combined ports of BC controller using CMY-
R160-J1.
When connecting Indoor units to 1 port of BC controller or 2
combined ports of BC controller using CMY-R160-J1 or CMY-
Y102SS-G2 is applicable, like Group 1 and 2 in Fig. 1
Caution: Mixed cooling and heating mode at the same time for
Indoor units connecting to 1 port or 2 combined ports is not
available.
2. Piping at the installation site
The connection of CMY-R160-J1 to BC controller and pipe leading to Indoor units is referable to Fig. 2. Non-oxidized brazing is
necessary. All piping must be careful to avoid foreign material getting inside.
After piping and air-tight testing, insulation work to the Joint and pipe should be done. Details is available at the Installation Manual.
Joint kit "CMY-R160-J1" for BC controller is used to combine 2 ports of the BC controller at a PURY/PQRY system so as to
enable down-stream Indoor capacity above P54 as shown in Fig. 1.

The Joint kit include following items:
Have pipe expansion of indoor unit connecting port by
cutting the piping at the cutting point.
Remove burr after cutting the piping to prevent entering
the piping.
Check that there is no crack at the pipe expansion part.
