Unit
(1) Connection communication line
Remove the cover of the electrical cabinet of the valve cage. Introduce the communication lines for the outdoor
and indoor units through holes at the lower right of the electrical cabinet and crimp them on the communication
terminal block. Thereafter, fix the lead wires using crimping pliers to prevent the communication line from falling
off due to external force.
(2) Connection of power line and ground wire :
Remove the cover of the electrical cabinet of the connection kit. Introduce power lines through holes at the
lower left of the electrical cabinet and crimp them on the communication terminal block. Thereafter, fix the
power lines using crimping pliers to prevent them from falling off due to external force.
1) Do not route the communication lines and power lines together. Otherwise, they could malfunction or
electrical disturbances could occur.
2) Ensure that the ground wires are properly crimped. Otherwise, grounding will turn out to be ineffective.
