pipe connection can be performed from 3 directions, rear, right
and upper. For rear and upper pipe connections, the plastic cap
is attached at knockout hole for the refrigerant pipe and the drain
pipe. Cut out the knockout hole of cap for piping and attach the
cap again after running the refrigerant pipe through the cap.

suspension band to prevent dangling.
