Power Supply
208/230V
1 ~ 60Hz
[ PRECAUTIONS ]
1. Make sure that the ground fault circuit interrupter is
designed to protect the air conditioner from ground faults,

(2) Actuation
• The following table explains FORCED OFF and ON/OFF
OPERATIONS in response to Input A.
FORCED OFF
Input "ON" stops operation (impossible by
remote controllers.)
Input OFF enables control by remote con-
troller.
(3) How to select FORCED OFF and ON/OFF OPERATION
• Turn the power on and then use the remote controller to
select operation.
10-5 CENTRALIZED CONTROL
