11 How to exchange main parts
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>
Ensure that no water pressure is present when replacing the water circuit (circulation pump, heater unit, flow sensor, etc).
After a repair is complete, perform a test run (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 test run.
<Watch out for fire>
Observe the following instructions when repairing the refrigerant cycle.
CAUTION
<Wear gloves>
Wear gloves (∗) when performing repair.
Failure to do so may cause an injury when accidentally contacting the parts.
∗
<Remove the ground wire>
The ground wire is connected between the product body and the front cabinet, so do not pull it too hard.
<Change O-ring>
If you disconnect the O-ring connection, be sure to replace it with a new O-ring. It may cause water leakage.
