How to Exchange Main Parts

1. Hydro Unit

WARNING

<Turn off the power breaker>
Because the electrical components are energized with high voltage, always turn off the power breaker before
starting to work.

<Check>
After a repair is complete, perform a trial operation (after attaching the front panel, upper and lower cabinets, and
side cabinet) and check that no abnormality including smoke or abnormal noise occurs. Failure to do so may cause
a fire or an electric shock. Place the cabinets before making a trial operation.

<Watch out for fire>
Observe the following instructions when repairing the refrigerant cycle.
(1) Watch out for surrounding fire. Always put out the fire of stove burner or other devices before starting the repair.

Should the fire fail to be put out, the oil mixed with refrigerant gas could catch fire.

(2) Do not use a welder in a closed room.

A room with no ventilation may cause carbon monoxide poisoning.

(3) Keep away flammable materials.

The materials may catch the fire of a welder.

CAUTION

<Wear gloves>
Wear gloves (

∗

) when performing repair.

Failure to do so may cause an injury when accidentally contacting the parts.

∗

: Thick gloves such as cotton work gloves

No.
