Electric shock
Since the control panel carries AC 220V, you may suffer electric shock if touching any live component
of it. Thus, please wear insulating gloves in power-on maintenance or while removing the dangerous
component to be replaced to avoid electric shock.
As some components in the inverse circuit carry high voltage, please take care in power-on operation.

Please use original components for maintenance.
Components of this appliance feature flame retardance, voltage withstanding and other safety
characteristics, thus please use components with the same characteristics for replacement. Especially

component list, please use original components.
■
If required, please install and wire the components as before.
For safety, this product is provided with some insulating materials such as hose and adhesive tape;
besides, some components fi xed on the upper part of the printed circuit board. When using ties to
secure the internal wiring, do keep them away from heating or high-voltage components. The wiring
must be placed well as before.
The replaced lead shall be kept away from the sharp edges of component.

After maintenance, please conduct safety inspection.
Please inspect whether all the usable screws, components and leads dismantled have been put
back to the original places correctly and whether there are any components whose performance has
degraded near the maintenance area.
