CAUTION : HIGH VOLTAGE
The high voltage circuit is incorporated.
Be careful to do the check service, as the
electric shock may be caused in case of
touching parts on the P.C. board by hand.
The 4-way valve coil is turned on while the cooling operation
1. indicates the terminal block.
Alphanumeric characters in the cycle indicate the terminal No.
2. The two-dot chain line indicates the wiring procured locally.
