This symbol means an action is prohibited.

This symbol means an instruction must be followed.

Be sure to keep the operating instructions in a place accessible to users of this unit.

< Label on the unit >

This mark is labeled on the cover in which the electrical components of high voltage

are enclosed to prevent the electric shock.

The cover should be removed by a qualified engineer or service personnel only.

WARNING

As with any equipment that uses CO2gas, there is a likelihood of oxygen depletion in the vicinity

of the equipment. It is important that you assess the work site to ensure there is suitable and

sufficient ventilation. If restricted ventilation is suspected, then other methods of ensuring a

safe environment must be considered. These may include atmosphere monitoring and

warning devices.

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 and take an adequate precaution to prevent the unit from

turning over. 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.

Always ground (earth) the unit 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.

Connect the unit to a power source as indicated on the rating label attached to the unit. Use

of any other voltage or frequency other than that on the rating label may cause fire or electric shock.

Never store volatile or flammable substances in this unit if the container cannot be sealed. These

may cause explosion or fire.

Do not insert metal objects such as a pin or a wire into any vent, gap or any outlet on the unit.

This may cause electric shock or injury by accidental contact with moving parts.

Use this unit in safe area when treating the poison, harmful or radiate articles. Improper use

may cause bad effect on your health or environment.

Turn off the power switch (if provided) and disconnect the power supply to the unit prior to

any repair or maintenance of the unit in order to prevent electric shock or injury.

Do not touch any electrical parts (such as power supply plug) or operate switches with a wet

hand. This may cause electric shock.

WARNING

PRECAUTIONS FOR SAFE OPERATION

Ensure you do not inhale or consume medication or aerosols from around the unit at the time of

maintenance. These may be harmful to your health.

Never splash water directly onto the unit as this may cause electric shock or short circuit.

Never put containers with liquid on the unit as this may cause electric shock or short circuit when

the liquid is spilled.

Never bind, process, or step on the power supply cord, or never damage or break the power

supply plug. A broken supply cord or plug may cause fire or electric shock.

Do not use the power supply cord if its plug is loose. Such power supply cord may cause fire or

electric shock.

Never disassemble, repair, or modify the unit yourself. Any such work carried out by an

unauthorized person may result in fire, or electric shock or injury due to a malfunction.

Disconnect the power supply plug if there is something wrong with the unit. Continued

abnormal operation may cause electric shock or fire.

When removing the power supply plug from the power supply outlet, grip the power supply

plug, not the cord. Pulling the cord may result in electric shock or fire by short circuit.

Disconnect the power supply plug before moving the unit. Take care not to damage the power

supply cord. A damaged cord may cause electric shock or fire.

Disconnect the power supply plug when the unit is not used for long periods. Keeping the

connection may cause electric shock, current leakage, or fire due to the deterioration of insulation.

If the unit is to be stored unused in an unsupervised area for an extended period, ensure that

children do not have access and that doors cannot be closed completely.

The disposal of the unit should be accomplished by appropriate personnel. Remove doors to

prevent accidents such as suffocation.

Do not put the packing plastic bag within reach of children as suffocation may result.

Do not position this unit and the other unit so that it is difficult to operate the disconnection of

the power supply plug. Failure to disconnect the power supply plug may cause fire if there is

something wrong with the unit.

Flammable and explosive product. This product contains flammable refrigerant. Do not damage

or break the pipework.

WARNING

PRECAUTIONS FOR SAFE OPERATION

Use a dedicated power source (a dedicated circuit with a breaker) as indicated on the rating label

attached to the unit. A branched circuit may cause fire resulting from abnormal heating.

Connect the power supply plug to the power source firmly after removing the dust on the plug.

A dusty plug or improper insertion may cause a heat or ignition.

Never store corrosive substances such as acid or alkali in this unit if the container cannot be

sealed. These may cause corrosion of inner components or electric parts.

Check the setting when starting up of operation after power failure or turning off of power

switch. The stored items may be damaged due to the change of setting.

Be careful not to tip over the unit during movement to prevent damage or injury.

Prepare a safety check sheet when you request any repair or maintenance for the safety of service

personnel.
