Caution,

1.To protect each Fan motors and Compressors from abnormal current, these Over current relays<51C>,<51F1,2>are installed.

Therefore,do not change factory set value of these Over current relays. 2.To protect the compressor from frequently "ON-OFF" ,timer<TM>is

installed. Therefore,do not change factory set value of this timer.

Note:

1.The dotted lines show field wiring.

2.The figure in the parentheses show field supply parts. 3.Color of earth wire is yellow and green twisting. 4.Not specified color of wire is brown.

5.Specification subject to change without notice.
