PRECAUTIONS FOR SAFE OPERATION
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 splash water directly onto the unit as this may cause electric shock or short circuit.
Use a dedicated power source as indicated on the rating label attached to the unit.
Remove dust from the power supply plug before inserting in a power source. A dusty plug or
improper insertion may cause a hazard.
Use a power supply outlet with ground (earth) to prevent electric shock. If the power supply
outlet is not grounded (earthed), 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.
Check the gas type and ensure that it is fit for the purpose. Make sure that all pipes are
connected correctly and are not liable to become disconnected. Ensure that the gas pressure
is set at the specified value. Improper connection of the gas pipe or use of incorrect gas
pressure may result in leakage of CO
2
gas. Elevated level of CO
2
gas can be hazardous to
health and may lead to asphyxiation and risk of death.
Never store volatile or flammable substances in this unit. This may cause explosion or fire.
Ventilate a room air occasionally when using CO
2
gas for control. The gas density will increase
in an enclosed small room and high level of gas density can be hazardous to health. In addition,
avoid inhaling the chamber air directly when opening the door if CO
2
gas is used.
Si l’appareil est utilisé dans un evdroit restreint, le niveau de la densité
CO
2
de l’air peut s’élever
et peut être nocif aux humains. Évitez d’aspirer l’air provenant de l’intérieur de l’appareil quand
vous ouverz la porte.
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.
