WARNING

PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. OVERFILLING OF THE TANK MAY CAUSE VIOLENT EXPLOSION AND POSSIBLE INJURY OR DEATH. Refer to the instruction manual for tank specifications and ordering

information. Do not recover refrigerants into a non-refillable storage container! Federal regulations require refrigerant to be transported only in containers meeting DOT spec. 4BW or DOT spec. 4BA.

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 servicing unit. Refer to the instruction manual.

TO REDUCE THE RISK OF FIRE, avoid the use of an extension cord because the

extension cord may overheat. However, if you must use an extension cord, use No. 14 AWG at the 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 all safety devices are functioning properly before operating the unit. Before operating, read and follow the instructions and warnings in this manual.

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

Use only with R-12 or R-134a. This equipment is not designed for any other purpose than recovering, recycling or recharging refrigerants! Do not mix refrigerant types!

ATTENTION!

Ce réservoir sous pression contient du frigorigène liquide. S’il est surchargé, ce réservoir peut exploser et causer des blessures ou la mort.

ATTENTION. Débrancher avant la maintenance. ATTENTION. Pour réduire les risques d’incendie, ne pas utiliser de cordon prolongateur de section inférieure à 14 AWG

de facon à éviter la surchauffe du cordon. ATTENTION. Utiliser seulement du frigorigène R-134a.

OPERATING NOTES

At temperatures exceeding 120

Use the Series 348002K/348012K only with R-12 or R-134a! Cross-contamination with other refrigerant types will cause severe damage to the A/C system 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 or mist. Exposure may irritate eyes, nose and throat. To remove R-12 or R-134a from the A/C system, use service equipment certified to meet the requirements of SAE-J2210 (R-12 or R-134a recycling equipment). If accidental system discharge occurs, ventilate work area before resuming service.

R-12 or HFC-134a service equipment or vehicle A/C systems should not be pressure tested or leak tested with compressed air. Some mixtures of air/HFC-R-12 /R-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.

F / 49oC, wait 10 minutes between recovery jobs.

R-12 and R-134a WARNINGS!
