1. The indoor unit whose liquid pipe is connected to A1 in A system is called unit A1, its communication wire
of A1(3)
、
A1(4) should be connected to A1(P)
、
A1(Q) respectively.
2. The indoor unit whose liquid pipe is connected to A2 in A system is called unit A2, its communication wire
of A2(3)
、
A2(4) should be connected to A2(P)
、
A2(Q) respectively.
3. The indoor unit whose liquid pipe is connected to B1 in B system is called unit B1, its communication wire
of B1(3)
、
B1(4) should be connected to B1(P)
、
B1(Q) respectively.
4. The indoor unit whose liquid pipe is connected to B2 in B system is called unit B2, its communication wire
of B2(3)
、
B2(4) should be connected to B2(P)
、
B2(Q) respectively.
Note: Because the customers themselves match the communication wire, and the P and Q are
nonpolar, the customers must use shielded communication wires.
