PRECAUTIONS FOR SAFE OPERATION
WARNING
Do not use the unit outdoors. Current leakage or electric shock may result if the unit is exposed to rain water.
Only qualified engineers or service personnel should install the unit. The installation by unqualified personnel may cause electric shock or fire.
Install the unit on a sturdy floor. If the floor is not strong enough or the installation site is not adequate, this may result in injury from the unit falling or tipping over.
Never install the unit in a humid place or a place where it is likely to be splashed by water.
Deterioration of the insulation may result which could cause current leakage or electric shock. 
Never install the unit in a flammable or volatile location. This may cause explosion or fire.
Never install the unit where acid or corrosive gases are present as current leakage or electric
shock may result due to corrosion.
Use a dedicated power source as indicated on the rating label attached to the unit. Ensure that a suitable fuse of adequate amperage is used to allow for compressor start up.
Remove dust from the power supply plug before inserting in a power source. A dusty plug or improper insertion may pose a hazard.
Use a power supply outlet with ground (earth) to prevent electric shock. If the power supply outlet is not grounded, it will be necessary to install a ground by qualified engineers.
Never ground the unit through a gas pipe, water main, telephone line or lightning rod. Such
grounding may cause electric shock in the case of an incomplete circuit.
Do not insert metal objects such as a pin or a wire into any vent, gap or any outlet for inner air
circulation. This may cause electric shock or injury by accidental contact with moving parts. 
Never store volatile or flammable substances in this unit. This may cause explosion or fire.
Never store corrosive substances in this unit. This may lead to damage to the inner components or electric parts.
If this unit is to be used for storing poisons, radioactive material or other harmful products, ensure that it is in a safe area. Failure to do so may lead to an adverse effect on the health of personnel in the area and the local environment. In this case, a request for repair or maintenance will necessitate a safety check sheet for maintenance personnel.
