2) Remove screw (screw 2 pcs.) of the upper

 

 

 

 

 

 

 

P.C. board

 

 

 

 

 

 

 

 

 

part of the front cabinet.

 

 

 

 

 

 

• If removing the inverter cover in this

condition, P.C. board can be checked.

 

 

 

 

 

 

 

 

 

• If there is no space above the unit, perform

 

 

 

 

 

 

 

 

 

work of 1 in ‚.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Be careful to check the inverter because

 

 

 

 

 

 

 

 

 

high-voltage circuit is incorporated in it.

NOTE

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This capacitor is one with mass capacity.

 

 

 

 

 

 

 

 

 

Therefore, it is dangerous that a large

 

 

 

 

 

 

 

 

 

spark generates if short-circuiting

7)Pull the inverter box upward.

8)Disconnect connectors of various lead wires.

Requirement

As each connector has a lock mecha- nism, avoid to remove the connector by holding the lead wire, but by holding the connector.

Be sure to remove the connector by holding the connector, not by pulling the lead wire.
