WARNINGS

ALLOW ONLY QUALIFIED PERSONNEL TO OPERATE THE UNIT. Before operating the unit, read and follow the instructions and warnings in this manual. The operator must be familiar with air conditioning and refrigeration systems, refrigerants, and the dangers of pressurized components. If the operator cannot read English, operating instructions and safety precautions must be read and discussed in the operator’s native language.

–Si el operador no puede leer inglés, las instrucciones de operación y las precauciones de seguridad deberán leerse y comentarse en el idioma nativo del operador.

–Si l’utilisateur ne peut lire l’anglais, les instructions et les consignes de sécurité doivent lui être expliquées dans sa langue maternelle.

PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. Do not overfill the internal storage vessel, because overfilling may cause explosion and personal injury or death. Do not recover refrigerants into nonrefillable containers; use only federally authorized refillable containers (DOT spec. 4BW or 4BA).

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

DO NOT BREATHE REFRIGERANT AND LUBRICANT VAPOR OR MIST. Exposure may cause personal injury, especially to the eyes, nose, throat, and lungs. Use the unit in locations with mechanical ventilation that provides at least four air changes per hour. If accidental system discharge occurs, ventilate the work area before resuming service.

DO NOT USE AN EXTENSION CORD. An extension cord may overheat and cause fire. If you must use an extension cord, use the shortest possible cord with a minimum size of 14 AWG.

TO REDUCE THE RISK OF FIRE, do not use the unit in the vicinity of spilled or open containers of gasoline or other flammable substances.

DO NOT USE COMPRESSED AIR TO PRESSURE TEST OR LEAK TEST THE UNIT OR VEHICLE AIR CONDITIONING SYSTEM. Some mixtures of air and R-134a refrigerant are combustible at elevated pressures.

These mixtures are potentially dangerous and may result in fire or explosion causing personal injury or property damage.

USE THE 34700Z UNIT WITH R-134a REFRIGERANT ONLY. The unit is designed to recover, recycle, and recharge only R-134a refrigerant. Do not attempt to adapt the unit for another refrigerant. Do not mix refrigerant types through a system or in the same container; mixing of refrigerants will cause severe damage to the unit and the vehicle air conditioning system.

USE THE 17700Z UNIT WITH R-12 REFRIGERANT ONLY. The unit is designed to recover, recycle, and recharge only R-12 refrigerant. Do not attempt to adapt the unit for another refrigerant. Do not mix refrigerant types through a system or in the same container; mixing of refrigerants will cause severe damage to the unit and the vehicle air conditioning system.

HIGH VOLTAGE ELECTRICITY INSIDE THE UNIT HAS A RISK OF ELECTRICAL SHOCK. Exposure may cause personal injury. Disconnect the power before servicing the unit.

OPERATING NOTE: At temperatures exceeding 120° F / 49° C, wait 10 minutes between recovery jobs.

34700Z Recovery, Recycling, Recharging Unit

Introduction

The 34700Z model is used on R-134a vehicles; the 17700Z model is used on R-12 vehicles. Both models are designed to be compatible with existing service equipment and standard service procedures.

Both models are UL-listed, single-pass systems that meet SAE specifications for recycled refrigerant. Follow the SAE-J2210 recommended service procedure for the containment of R-134a; follow the SAE-J1991 recommended service procedure for the containment of R-12.

The unit includes a 6 cfm (142 l/m) Robinair high vacuum pump for fast thorough evacuation. The recovery compressor is not a vacuum pump. The compressor pulls the A/C system to a partial vacuum only; use the unit’s vacuum cycle to remove moisture from the A/C system. (We recommend a minimum 15-minute vacuum, or follow the vehicle manufacturer’s recommendation.)

Note : R-134a systems require special oils. Refer to the A/C system manufacturer’s service manual for oil specifications.
