Precaution
During the service
During the service, check for damage, deformation, or deterioration of the power plug and the
electrical outlet.
- If any abnormality is found, repair or replace the power plug or electrical outlet to prevent electric
shock or fire.
When servicing the product, completely remove dust or foreign material from housing, connection,
and connector parts.
- It is to prevent fire caused by tracing or short circuit.
Check electrical parts, harnesses or connectors for any trace of moisture.
- When moisture exists, replace the parts or completely remove the moisture.
When fitting connectors to PBA terminals, make sure to push the connectors through until you hear
the
‘ click ’ sound.
- If connectors are loosely fitted, a product malfunction or fire may occur as a result.
If a harness or connector terminal is damaged (cut), do not repair but replace it.
- If it is repaired using materials such as insulating tapes, product malfunction or fire may occur as a
result.
After the service
After servicing the product, check the overall assembly status and terminal connection of terminals.
- If electrical wiring is under pressure or parts are fitted incorrectly, re-assemble the product.
Exercise caution not to have internal electrical wiring touches moving parts or sharp objects.
- Otherwise, product malfunction, short circuit, or fire may occur as a result.
After checking the product, tighten the fixing bolts firmly so that the product body is not shaky on the
toilet.

toilet, resulting in injury.
After servicing the product, make sure to check connections such as supply water valve, water
supply hose, or T-shaped valve for leaks.
- Otherwise electrical shock or injury may occur as a result.
Make sure to use a grounded electrical outlet. In the case of short circuit, grounding prevents electric
shock or injury.
- Make sure to connect the power plug to a dedicated electrical outlet with grounding terminals.
