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.
