    1. Precautions 1-1. Precautions for the Service • Use the correct parts when changing the electric parts. - Please check the labels and notices for the model name, proper voltage, and proper current for the electric parts. • Fully repair the connection for the types of harness when repairing the product after breakdown. - A faulty connection can cause irregular noise and problems.

  • Page 6: Precautions For Handling Refrigerant Of The Dvm Chiller

    1-4. Precautions for Handling Refrigerant of the DVM CHILLER Environmental Cautions: Air pollution due to gas release • Safety Cautions If liquid gas is released, then body parts that come into contact with it may experience frostbite/blister/numbness. If a large amount of gas is released, then suffocation may occur due to lack of oxygen. If the released gas is heated, then noxious gas may be produced by combustion.
