EXPLOSION/FLAME HAZARDS
• Never recover anything other than the approved refrigerants as specified on the machine.
Alternate refrigerants may contain flammables such as butane or propane and can explode or
cause a fire. Recovering alternate refrigerants will also void the warranty on your machine.
• For general safety reasons, at the end of the working day or in between services (when
services do not immediately follow), see to it that all valves on hoses and the machine are
closed.
ADDITIONAL SAFETY INFORMATION
For additional information concerning safety, refer to the following standards.
ANSI Standard Z87.1 — SAFE PRACTICE FOR OCCUPATION AND EDUCATIONAL EYE AND FACE PROTECTION -
obtainable from the American National Standards Institute, 11 West 42nd St., New York, NY 10036, Telephone
(212) 642-4900, Fax (212) 398-0023 - www.ansi.org
CAUTION: This equipment should be used in locations with mechanical ventilation that provides at least
four air changes per hour or the equipment should be located at least 18 inches (457 mm) above the
floor, or the equivalent.
CAUTION: Do not pressure test or leak test R234yf service equipment and/or vehicle air conditioning
systems with compressed air. Some mixtures of air and R234yf have been shown to be combustible at
elevated pressures. These mixtures, if ignited, may cause injury or property damage. Additional health
and safety information may be obtained from refrigerant manufacturers.
ATTENTION: Technicians using this equipment must be certified under EPA Section 609 (Environmental
Protection Agency).
WARNING: There is the possibility of refrigerant contamination in the refrigerant container or the mobile
A/C system being serviced or refrigerant container. Before recycling use proper equipment such as a
refrigerant identifier, if necessary.
NOTE: Use only new refrigerant oil to replace the amount removed during the recycling process. Used oil
should be discarded per applicable federal, state, and local requirements.
The manufacturer shall not be responsible for any additional costs associated with a product failure
including, but not limited to, loss of work time, loss of refrigerant, cross contamination of refrigerant,
and unauthorized shipping and/or labor charges.
IMPORTANT: R1234yf systems have special fittings (per SAE specifications) to avoid cross-contamination
with other systems. DO NOT adapt your unit for a different refrigerant — system failure will result.
PERIODICALLY INSPECT AND MAINTAIN REFRIGERANT HOSES AND SEALS TO ENSURE THAT HOSES AND
SEALS PREVENT THE ADDITION OF EXCESS AIR, DUE TO LEAKS, DURING THE RECOVERY PROCESS, WHICH
WOULD INCREASE THE NCG LEVEL IN THE RECOVERED REFRIGERANT.
CERTIFICATION
All technicians opening the refrigeration circuit in automotive air conditioning systems must now be certified
in refrigerant recovery and recycling procedures to be in compliance with Section 609 of the Clean Air Act
Amendments of 1990. For information on certification call MACS Worldwide at (215) 631-7020.
