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 el 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 non-refillable containers; use only federally authorized refillable containers (DOT spec. 4BW or 4BA).
ALL 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 17700-2K UNIT WITH R-12 REFRIGERANT ONLY. The unit is for recovering, recycling, and recharging 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.
USE THE 34700-2K UNIT WITH R-134a REFRIGERANT ONLY. The unit is for recovering, recycling, and recharging 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.
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.

Operating Instructions
OPERATING TIPS
Follow the SAE-J1991 recommended service procedure for the containment of R-12, and the SAE-J2210 recommended service procedure for the containment of R-134a.
The recovery compressor is not a vacuum pump. The compressor pulls the A/C system to a partial vacuum only. You must use the unit’s vacuum cycle to remove moisture from the A/C system. We recommend a minimum 15-minute vacuum, or follow the system manufacturer's recommendations.
This unit is designed to be used with the manifold gauge set built into the control panel.
The unit includes a 6 cfm (142 l/m) Robinair high vacuum pump for fast, thorough evacuation. Change the vacuum pump oil after every 10 hours of use.
R-134a systems require special oils. Refer to the A/C system manufacturer’s service manuals for oil specifications.
Pressing the START and STOP keys together for several seconds will exit any mode and reset the control.
NOTE: The following operating instructions are written to be used with the BASIC PROMPTS mode of operation. It is recommended that the BASIC PROMPTS mode is used until the operator becomes very familiar with the operation of the unit. See the OPERATING GUIDELINES section of this manual for instructions on how to select between BASIC PROMPTS and ADVANCED PROMPTS.

REPLENISHING A/C SYSTEM OIL
CAUTION! To prevent air from entering the A/C system, never let the
oil level drop below the pickup tube while charging or replenishing.
Before charging the A/C system, you must replenish any oil removed from the A/C system during the recovery process. Charge only the amount of oil that was removed from the A/C system during recovery. Check the oil drain bottle to determine the amount of oil that was removed during recovery. Empty the oil drain bottle before recovering the next A/C system to prevent an inaccurate oil charge. NOTE: If no oil was removed from the A/C system during recovery, DO NOT charge any oil into the A/C system.
THE VACUUM CYCLE MUST RUN COMPLETELY OR THE OIL INJECT WILL NOT OPERATE.
1. Select the correct oil for the A/C system being serviced. Refer to the vehicle manufacturer's service manual.
2. Adjust the o-ring around the oil injector bottle to the required oil charge level. For example, if the bottle's oil level is at 4 ounces, and you need 1/2 ounce of oil to replenish the A/C system, place the o-ring at the 3 1/2 ounce level.
3. Reattach the oil injector bottle to the unit.
4. Close the Low Side manifold valve. Put the High Side valve in the Oil Inject/ Charge position.
5. Press the F1 (INJECT OIL) button once and release it when it “beeps.” Press the F1 button again and hold it until the oil level reaches the o-ring.
6. Press the STOP button after the oil charge is complete to recharge the A/C system with refrigerant. You must recharge the AC system with refrigerant at this time to ensure all of the oil is delivered.

CHANGING THE VACUUM PUMP OIL
For maximum vacuum pump performance, change the vacuum pump oil after every 10 hours of operation.
1. Turn on the MAIN POWER switch.
IMPORTANT!
Review current local, state, and federal statutes, cases, laws, and regulations to determine the current status and appropriate disposal method for pump oil. It is the responsibility of the user to determine if a material is a hazardous waste at the time of disposal. Ensure that you are in compliance with all applicable laws and regulations.
2. Press the MENU button.
NOTE: Do not connect the service hoses to a vehicle.
3. Use the arrow keys to select CHANGE VACUUM PUMP OIL, and press
START.
4. Press START again to begin.
5. The vacuum pump will run for two minutes. Allow the vacuum pump to run until it automatically stops.
6. Remove the black plastic plug on the oil fill port of the vacuum pump.
7. Remove the oil drain cap from the vacuum pump, and drain the oil into a suitable container for correct disposal.
8. Replace the oil drain cap.
9. Attach the flexible tube and cap to the oil bottle, and pour eight ounces of vacuum pump oil into the fill port.
10. Press the START key. While the vacuum pump is
running, slowly add oil until the level rises to the center of the reservoir's sight glass.
