Single-dotted lines indicate wiring not
supplied with the unit.
*2.
Dot-dash lines indicate the control box
boundaries.
*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
f the power
,keep the unit of
f for at
least 10 minutes, and confirm that the voltage
at both ends of the main capacitor (C1) has
dropped to DC20V or less.
