1. Firstly check that there is electrical leakage in the main body of the product.
2. Perform work always after removing the power plugs in handling with the part where electricity conducts through.
3. Wear a rubber gloves(insulation gloves) for preventing electrical shock accident in case of testing with power on.
4. Always check rated current, voltage and capacity in using the instruments.
5. Exercise care so that water does not enter into electrical parts around the machine room.
6. Take care so that things should not fall down by removing them cleanly on the product when leaning the product forward
or backward. Especially, take care of thin things (glass panels, books).
7. Ensure to consult the repair and maintenance center shop when the cold storage cycle is damaged (to prevent that gas
inside of the cycle gets a room dirty).
