• Stop the recycling proces s if you develop momentary eye, nose, or throat irritation as
this indicates inadequate ventilation. Stop work and take necess ary steps to im prove
ventilation inthe work area.
HEAT/FREEZ ING HAZARDS
WAR NING:
• When under press ure, refrigerants become liquid. When accidentally
releas ed from the liquid state they evaporate and become gaseous. As they
evaporate,they can freeze or fros tbite tissue very rapidly. When these gases
are breathed, the lungs can be s eriously damaged. If sufficient quantities are
taken into the lungs, death can result. If you believe you have expos ed your lungs to
releas ed refrigerant, seek immediate medical assis tance.
• Refrigerants can cause frostbite and severe burns to exposed skin. Refrigerants are
under pressure and canbe forcibly sprayedin all directions ifcarelessly handled. Avoid
contact with refrigerants and always wear hand coverings and make certain other
exposed s kin is properly covered.
• Refrigerants can also s everely injure or cause permanent blindness to unprotected
eyes. Refrigerants are under press ure and can be forcibly s prayed in all directions if
carelessly handled. Avoid contact with refrigerants andalways wear safetygoggles.
EXPLOSION/FLAME HAZARDS
WAR NING:
• Never recover anything other than the approved refrigerants as specified on
theVR-6000. Alternate refrigerants m ay contain flam mables such as butane
or propaneand can explode or cause a fire. Recovering alternate refrigerants
will also void the warranty on your VIPER VR-6000.
• For generalsafetyreasons, attheend ofthe working day or in between services (when
services do not immediatelyfollow), s ee to it that all valves on hoses and tanks are
clos ed.

ABOUT THE VIPER A/C AIR CO NDITIONING SERVICE CENTER
The ozone layer around the earth’s atmos phere is a thin protective covering. It acts as a
shield against the sun’s destructiveultravioletrays. Without the ozone layer the very exis tence
of our planet would be in question. Scientific studies show that the ozone layer is being
destroyed at an alarming rate. It has been es tablished that emissions from refrigerants,
such as R-12, contain chlorofluorocarbons (CFC’s), which are the leading caus e of ozone
depletion. One CFC molecule has been s hown to destroyup to 100,000 ozone molecules.
Your VIPER VR-6000 incorporates a highly accurate electronic scale for determ ining
charging weights, etc. Other functions can also beperformed with the electronic scale as you
will discover during the operating procedures. Either standard or m etric units of measure
can be selected. Your new VIPER VR-6000 has been designed s pecifically touse R-134a, to
operatewithin theobjectives oftheMontreal Protocol.

OPERATION INSTRUCTIONS
RECOVER AND RECYCLE REFRIGERANT FROM AN AC SYSTEM
1. Be sure that the shutoffvalves are off prior toattaching to a vehicleAC s ystem.
2. Attach themachine 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 system and are open only when connected
with the knurledknobs turnedclockwise. Slide thecollar ofthe fitting back and pres s to
theappropriate fitting.
• Blue hose to the low side of AC system
• Red hose to thehigh s ide of AC system
3. Set MAIN POWER (k, Figure 3) ON.
4. Open the valves on the s ervice hoses by turning the knurled knob clockwise (Figure
12). This will allow refrigerant to flow tothe vehicle.
5. Observe the pressure readings on the low and high side manifold gauges. If the
readings are zero,then repair AC system leak orproceed to vacuum phas e.
6. Open the High Side andLow Side valves on the controlpanel ofthe machine.
7. Press and hold the SEL keyuntil the LED corresponding to “RECOVERY” lights; then
pres s GO. At this point the RECOVERY/RECYCLING phase will begin and the
“Recovery” LEDwill flas h.
8. During the RECOVERY/RECYCLING phas e the amount of refrigerant recovered from
thevehicle will be displayed. Upon completion of the recovery phase the machine will
stop and hold three m inutes.
9. During this time themachine automatically discharges the us ed oil. It will be necess ary
to m onitor this oil dumping to determ ine the am ount of oil that must be added to the
vehicle. When the oil discharge is complete, measure, record and em pty the oil
discharge bottle. This amount will be added to the AC system before charging. When
there is noincrease insystem pressure, the vacuum pump will start and evacuate the
input oil s eparator insidethe VR-6000.
10. If, during this 3-minute time period, the residual refri gerant left in the A/C system
caus es the pres sure to increase, themachine will automatically resume recovering the
refrigerant. When this phase is complete the machine will sound and audible alarm,
and switch to the REF RIGERANT A VAILA BLE display.
11. Clos e the High Side andLow Side panel valves.
12. Setthe MAIN POWER switchOFF.
13. Disconnect the machine if desired. (See DISCONNECTING THE MACHINE FROM A
VEHICL E.)
14. Make necess ary repairs tothe A/C system being serviced.
REMO VING NON-CONDENSABLE GASES
As non-condensable gases accumulate in the refrigerant storage tank, excessive pres sure
is created. The m ost noticeable symptom of excess press ure is a slow down of refrigerant
flow duringtherecovery process. Inm ost cases, you will not notice a reduction in refrigerant
recovery rate until the nominal press ure in the storage tank is 20 ps ig above the normal
pres sure, as listed on the purge chart. C he ck for non-condensable gases after each
recovery phase. The table provided below (Figure 13)is used to determine when an exces s
ofnon-condensable gases has accumulated in the refrigerants torage tank.
16
INSTRUCTIONS MA NUAL
Proceedas follows:
“REFRIGERANT AVAILABLE” LED must light, if it is neces sary pres s the SEL key to switch
th e ligh t to “R EFRIGERANT AVA ILABL E” LED.
1. Press once the “°F” key in order to display the refrigerant tank temperature (in
Fahrenheit degree), press it a s econd time to display the temperature in Celsius
degree)
2. Read thestoragetank pressure ofthetank gauge
3. Find the temperature in the TEMP °F column for that tank then read the associated
PR ESSURE colum n in ps ig.
4. If the related TANK PRESSURE gauge (A4, fig.5) reads LOWER or EQUAL than the
nominal press ure listed in the table for the respective tank temperature, IT IS NOT
NECESSARY to vent the non-condensablegases from the tank.
5. If the related TANK PRESSURE gauge (A4, fig.5) reads HIGHER than the nominal
pres sure listed in the table for the respective tank temperature, you s hould vent the
non-condensable gases from the tank. This is accom plished byopening the air purge
valv e as shown in figures 1,2,3, & 4.
6. Press the STOP keyto exit the reading of the tank temperature
7. Slowly open the air purge valve (r,fig.2) counterclockwise (turn ~20 degree)

vacuum time value.
2. During the vacuum phase, the display will clock its duration. Leave the machine
running until the displayreads 0000 and the pump stops autom atically.
3. Close all the valves and read the vacuum value on press ure gauges (A1) and (A2).
Wait for about 2 minutes, and then check that the pressure has not increased during
the interval. An increase in press ure s ignals leaks in the A/C system. Locate and
eliminate the leaks ; repeatthevacuum phase.
WARNING: Avoid breathing A/C refrigerant and lub ricant vapor mist. Exp osure may
irritate eyes, nose, and throat. To remove HFC-134a from the A/C system, use service
equipment certified to meet the requirements of SAE J2210 (HFC-134a recycling
eq uipment). Additional health and saf ety information may be obtained from add itional
refrigerant and lubricant manufacturers.

CALIBRATING THE ELECTRONIC SCALE
This operation s hould be performed when the s cale values displayed are out of line with
known values.The operations listed below must be performed with the maximum attention
and care. Always observe the precautions outlined in this section. Always place the weights
carefully on the scale plate, one at a time. Always place the weights the center of the scale
plate.Proceed as explained below tocalibrate the s cale (see fig. 1,2, 3, & 4). Disconnectthe
machinefrom m ain power supply. Procure a known reference weight (50 lbs). Remove the
plasticcover onthe rear of the m achineto access the machine bottle. Close the blue and red
valves on the storage tank. Remove the s torage tank locking bolts. Separate the heater

blanket(i) from the s torage tank (donot touch or disconnect the wires of the heater blanket).
Extreme care must be taken when removing the storage tank, so as to avoid pulling
wires loose anddamaging the copper tubing.
Remove the s torage tank (f) from its seat, leavingthe heater blanket around the s cale plate.
Rest the s torage tank on a stand at least 10” in height. Switch on the MACHINE. Be careful
not to touch any electrical wires . Wait at least 10 s econds and press STOP to s ilence the
alarm . Press the INCREASE and ARROW keys s imultaneously and hold down for about 5
seconds. The value displayed at this point will correspond to the scale zero value. Press
down lightlyon the s cale plate; the value should increase. If it does not, replace the charge
cell. Press the ENTER key to m emorize the value. In this phase, take care that nothing
touches the s cale plate). Place the reference weight (50 lbs) carefully at the center of the
scale plate andcheck that the displayed value increases accordingly. Press the SEL keyand
us e the INCREA SE & ARROW keys to typ e in the 4 figures of the ref erence weight. Press
ENTER. The display reading should be the reference weight minus the weight of the em pty
bottle (tare weight).
Remove the reference weight. Switch off the machine and disconnect from main power
supply. Replace the s torage tank in its s eat on the scale plate. Switch on the MACHINE,
taking care not to touch any electrical wires . Check calibration: place a known reference
weight onthe bottle and check that the displayed availability value increases bythe value of
theknown reference weight±2%. Removethe reference weight. Switch off the m achine and
disconnect from m ain s upply.Replace thestoragetank lockingbolts . Open the red and blue
storage tank valves. Replace the rear plas ticcover.
NOTE: In order to check the scale calibration the unit must be displaying a positive value for
REFRIGERANT AVAI LABLE,if the display is reading zero additional weight must be added
to the top of the tank to get a positive reading. The known weight is then added and the
change in weightis verified as the k nown weight.
VACUUM PUMP
Perform the operations listedbelow on a routine basis in order to ensure good operation of
thevacuum pump.
