WARNING

PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. OVERFILLING OF THE TANK MAY CAUSE VIOLENT EXPLOSION AND POSSIBLE INJURY OR DEATH. Safety devices require the use of only authorized refillable tanks. Refer to the instruction manual for tank specifications and ordering information. Do not recover refrigerants in a non-refillable storage container! Regulations require refrigerant to be transported only in specifically authorized containers.

ALL HOSES MAY CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contact with refrigerant may cause injury. Wear proper protective equipment, including safety goggles. Disconnect hoses with extreme caution.

HIGH VOLTAGE ELECTRICITY INSIDE PANELS. RISK OF ELECTRICAL SHOCK. Disconnect power before service unit. Refer to the instruction manual.

TO REDUCE RISK OF FIRE, avoid the use of an extension cord. The extension cord may overheat. If you must use an extension cord, the cord must be 14 AWG minimum and as short as possible. Do not use this equipment in the vicinity of spilled or open containers of gasoline or other flammable substances.

Use this equipment in locations with mechanical ventilation that provides at least four air changes per hour or locate the equipment at least 18 inches above the floor.

Make certain that all safety devices are functioning properly before operating the unit. Before operating, read and follow the instructions and warnings in the manual.

CAUTION: SHOULD BE OPERATED BY QUALIFIED PERSONNEL. Technician must be familiar with air conditioning and refrigeration systems, refrigerants and the dangers of pressurized components.

Use with the R-134a refrigerant only. This equipment is not designed for any other purpose other than recovering, recycling and charging refrigerants. Do not mix refrigerant types.

OPERATING NOTES

Change the filter-drier when the display shows Change Filter message. Follow the instructions for the changeover. At temperatures exceeding 120 °F / °C, wait 10 minutes between recovery jobs.

R-134a WARNINGS!

Use the MAC2000 unit only with R-134a refrigerants. Cross-contamination with other refrigerant types will cause severe damage to the A/C systems and to service tools and equipment. Do not mix refrigerant types through a system or in the same container.

Avoid breathing A/C refrigerant and lubricant vapor mist. Exposure may irritate eyes, nose and throat. To remove R-134a from the system, use service equipment certified to meet the requirements of SAE-J2210 (R-134a recycling equipment). If accidental system discharge occurs, ventilate work area before resuming service.

HFC-134a service equipment or vehicle A/C systems should not be pressured tested or leak tested with compressed air. Some mixtures of air/HFC-134a have been shown to be combustible at elevated pressures. These mixtures are potentially dangerous and may result in fire or explosion causing injury or property damage.

Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.
