• After power is supplied or after an operation stop for a while, a small clicking noise may be heard from the inside of the branch box. The electronic expan-
sion valve is opening and closing. The unit is not faulty.
• Be sure to perform the test run for each indoor unit. Make sure each indoor unit operates properly following the installation manual attached to the unit.

wires.
