PRECAUTIONS FOR SAFE OPERATION

WARNING

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.

As with any equipment that uses CO2 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.

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

Never disassemble, repair, or modify the unit yourself. Any such work carried out by an unauthorized person may result in fire 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.

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. Always remove doors to prevent accidents such as suffocation.

Connect a carbon dioxide cylinder or a oxygen gas cylinder to this unit correctly. Incorrect connection may cause explosion or fire.

Ventilate the room air when using the carbon dioxide gas for the back-up system. The CO2

density level in the air could rise and may be harmful to humans.

Make sure to prepare a safety check sheet when you request any repair or maintenance for the safety of service personnel.
