– Contains fluorinated greenhouse gases as defined by the Kyoto Protocol
– Ozone-depleting potential OPD: 0
– Greenhouse potential GWP: 2088
– Water hazard class WGK: 1, with a slight risk to water
At any time the unit is operational, rotating machinery and electrically charged com-
ponents are present. When the unit is not electrically isolated:
• Ensure all guards and doors are closed.
• Only remove guards or open doors:
– When the unit has been electrically isolated.
– Sufficient time has been allowed for the rotating fan momentum to cease.

NOTICE
• Always refer to the Material Safety Data Sheet (MSDS) from the supplier.
– Information relating to hazards, handling and storage, first aid amongst other
information is contained within the MSDS.
• Store these document(s) along with the Multi-DENCO documents.
Due to the nature of a refrigeration circuit, a Multi-DENCO system can contain dan-
gerously hot and dangerous cold aspects within the same system or circuit. Failure
to wear PPE could result in moderate injury.
• Review the appropriate chapters for further information.
• Never touch any part of the refrigeration circuit with unprotected skin.
• Always conduct your own personal risk assessment to evaluate any further
requirements.
