1. Designing CMY-R160C-J to a PURY-HP-T(S)KMU/
Y(S)KMU system
The maximum of Indoor capacity for one port of BC controller
is P54. When the Indoor capacity is above P54, Joint kit CMY-
R160C-J is needed to combine two ports of BC controller to en-
large the capacity, like Groups 2 and 3 in Fig. 1.
A maximum of three Indoor units are allowed to connect to one
port of BC controller or two combined ports of BC controller us-
ing CMY-R160C-J.
When connecting Indoor units to one port of BC controller or
two combined ports of BC controller using CMY-R160C-J,
CMY-Y102SS-G2 or CMY-Y104C-G is applicable, like Groups
1 and 2 in Fig. 1
Caution: Simultaneous operation of cooling and heating
modes for Indoor units connecting to the same BC ports is not
available.
2. Piping at the installation site
Refer to Fig. 2 for connecting the CMY-R160C-J to the BC controller and the pipe leading to the Indoor units. Non-oxidized brazing
is necessary. Avoid getting foreign material inside the piping.
After piping and air-tight testing, insulate the joint and pipe. Details are available in the Installation Manual.
