NOTE:

As with any equipment that uses CO

gas, 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.

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
