OPERATION INSTRUCTIONS
RECOVER AND RECYCLE REFRIGERANT FROM AN AC SYSTEM
1. Be s ure that the s hut offvalves are offprior to attaching to a vehicle AC system.
2. Attach the m achine to the high and low sides of the AC system to be serviced. The R-
134a hoses have SAE approved s hut-off valves (quick disconnects). The hoses are
shut off when disconnected from the AC s ystem and are open only when connected
with the knurled knobs turned clockwise.Slide the collar ofthe fitting back and press to
the appropriate fitting.
• Blue hose to the low side ofAC system
• Red hose to the high side ofAC system
3. Set MAIN POWER (k, Figure 3) ON.
4. Open the valves on the service hoses by turning the knurled knob clockwise (Figure
12). This will allow refrigerantto flow to the vehicle.
5. Observe the pres sure readings on the low and high side manifold gauges. If the
readings are zero, then repair AC system leak or proceed to vacuum phase.
6. Open the High Side and Low Side valves on the control panel ofthe m achine.
7. Pres s and hold the SEL key until the LED corres ponding to “RECOVERY” lights; then
press GO. At this point the RECOVERY/RECYCLING phas e will begin and the
“Recovery”LED will flash.
8. During the RECOVERY/RECYCLING phase the amount of refrigerant recovered from
the vehicle will be displayed. Upon completion of the recovery phase the machine will
stop and hold three minutes.
9. During this time the m achine automaticallydischarges the us ed oil. Itwill be neces sary
to monitor this oil dumping to determ ine the am ount of oil that must be added to the
vehicle. When the oil discharge is complete, meas ure, record and empty the oil
discharge bottle. This amount will be added to the AC s ystem before charging. When
there is no increase in system pres sure, the vacuum pump will start and evacuate the
input oil s eparator inside the VR-6000.
10. If, during this 3-minute time period, the residual refrigerant left in the A/C system
causes the pres sure to increase, the m achine will automaticallyresume recovering the
refrigerant. When this phase is complete the machine will s ound and audible alarm ,
and switch to the REFRIGERANTA VAILAB LE display.
11. Close the High Side and Low Side panel valves .
12. Set the MAIN POWER switch OFF.
13. Disconnect the m achine if desired. (See DISCONNECTING THE MACHINE FROM A
VEHICLE.)
14. Make neces sary repairs to the A/C s ystem being serviced.
REMO VING NON-CONDENSABLE G ASES
As non-condensable gases accum ulate in the refrigerant s torage tank, exces sive press ure
is created. The most noticeable symptom of excess pres sure is a slow down of refrigerant
flow during the recoveryprocess. In most cases, you will not notice a reduction in refrigerant
recovery rate until the nominal press ure in the storage tank is 20 psig above the norm al
press ure, as listed on the purge chart. C he ck for non-condensable gas es aft er each
recovery phase. The table provided below (Figure 13) is used to determ ine when an excess
ofnon-condensable gases has accumulated in the refrigerantstorage tank.
