*3.Refer to the Data book for connecting input/output

signal connectors.

*4.Daisy-chain terminals (TB3) on the outdoor units in the

same refrigerant system together

.

*5.Faston terminals have a locking function.

Make sure the terminals are securely locked in place

after insertion. Press the tab on the terminals to

removed them.

*6.Control box houses high-voltage parts.

Before inspecting the inside of the control box,turn of
