Operating Instructions
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.
