•Avoid breathing AC refrigerant and lubricant vapor mist. Exposure may irritate eyes, nose, and throat. To remove HFC-134a from the AC system, use service equipment certified to meet the requirements of SAE J2210 (HFC-134a recycling equipment).
•Additional health and safety information may be obtained from additional refrigerant and lubricant manufacturers.
•Always perform vehicle service in a properly ventilated area. Never run an engine without proper ventilation for its exhaust.
•Stop the recycling process if you develop momentary eye, nose, or throat irritation as this indicates inadequate ventilation. Stop work and take necessary steps to improve ventilation in the work area.
HEAT/FREEZING HAZARDS
WARNING:
• When under pressure, refrigerants become liquid. When accidentally released from the liquid state they evaporate and become gaseous. As they evaporate, they can freeze or frostbite tissue very rapidly. When these gases are breathed, the lungs can be seriously damaged. If sufficient quantities are
taken into the lungs, death can result. If you believe you have exposed your lungs to released refrigerant, seek immediate medical assistance.
•Refrigerants can cause frostbite and severe burns to exposed skin. Refrigerants are under pressure and can be forcibly sprayed in all directions if carelessly handled. Avoid contact with refrigerants and always wear hand coverings and make certain other exposed skin is properly covered.
•Refrigerants can also severely injure or cause permanent blindness to unprotected eyes. Refrigerants are under pressure and can be forcibly sprayed in all directions if carelesslyhandled. Avoid contact with refrigerants and always wear safetygoggles.
EXPLOSION/FLAME HAZARDS
WARNING:
• Never recover anything other than the approved refrigerants as specified on the VR-6000. Alternate refrigerants may contain flammables such as butane or propane and can explode or cause a fire. Recovering alternate refrigerants will also void the warranty on your VIPER VR-6000.
•For general safetyreasons, at the end of the working dayor in between services (when services do not immediately follow), see to it that all valves on hoses and tanks are closed.

ABOUT THE VIPER A/C AIR CONDITIONING SERVICE CENTER
The ozone layer around the earth’s atmosphere is a thin protective covering. It acts as a shield against the sun’s destructive ultraviolet rays. Without the ozone layer the very existence of our planet would be in question. Scientific studies show that the ozone layer is being destroyed at an alarming rate. It has been established that emissions from refrigerants, such as R-12, contain chlorofluorocarbons (CFC’s), which are the leading cause of ozone depletion. One CFC molecule has been shown to destroy up to 100,000 ozone molecules. Your VIPER VR-6000 incorporates a highly accurate electronic scale for determining charging weights, etc. Other functions can also be performed with the electronic scale as you will discover during the operating procedures. Either standard or metric units of measure can be selected. Your new VIPER VR-6000 has been designed specifically to use R-134a, to operate within the objectives of the Montreal Protocol.

INSTRUCTIONS MANUAL
OPERATION INSTRUCTIONS
RECOVER AND RECYCLE REFRIGERANT FROM AN AC SYSTEM
1.Be sure that the shut off valves are off prior to attaching to a vehicle AC system.
2.Attach the machine to the high and low sides of the AC system to be serviced. The R- 134a hoses have SAE approved shut-off valves (quick disconnects). The hoses are shut off when disconnected from the AC system and are open only when connected with the knurled knobs turned clockwise. Slide the collar of the fitting back and press to the appropriate fitting.
•Blue hose to the low side of AC system
•Red hose to the high side of AC 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 refrigerant to flow to the vehicle.
5.Observe the pressure 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 of the machine.
7.Press and hold the SEL key until the LED corresponding to “RECOVERY” lights; then press GO. At this point the RECOVERY/RECYCLING phase 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 machine automatically discharges the used oil. It will be necessary to monitor this oil dumping to determine the amount of oil that must be added to the vehicle. When the oil discharge is complete, measure, record and empty the oil discharge bottle. This amount will be added to the AC system before charging. When there is no increase in system pressure, the vacuum pump will start and evacuate the input oil separator inside the VR-6000.
10.If, during this 3-minute time period, the residual refrigerant left in the A/C system causes the pressure to increase, the machine will automatically resume recovering the refrigerant. When this phase is complete the machine will sound and audible alarm, and switch to the REFRIGERANT AVAILABLE display.
11.Close the High Side and Low Side panel valves.
12.Set the MAIN POWER switch OFF.
13.Disconnect the machine if desired. (See DISCONNECTING THE MACHINE FROM A VEHICLE.)
14.Make necessary repairs to the A/C system being serviced.
REMOVING NON-CONDENSABLE GASES
As non-condensable gases accumulate in the refrigerant storage tank, excessive pressure is created. The most noticeable symptom of excess pressure is a slow down of refrigerant flow during the recovery process. In most cases, you will not notice a reduction in refrigerant recovery rate until the nominal pressure in the storage tank is 20 psig above the normal pressure, as listed on the purge chart. Check for non-condensable gases after each recovery phase. The table provided below (Figure 13) is used to determine when an excess of non-condensable gases has accumulated in the refrigerant storage tank.
16
INSTRUCTIONS MANUAL
Proceed as follows:
“REFRIGERANT AVAILABLE” LED must light, if it is necessary press the SEL key to switch the light to “REFRIGERANT AVAILABLE” LED.
1.Press once the “°F” key in order to display the refrigerant tank temperature (in Fahrenheit degree), press it a second time to display the temperature in Celsius degree)
2.Read the storage tank pressure of the tank gauge
3.Find the temperature in the TEMP °F column for that tank then read the associated PRESSURE column in psig.
4.If the related TANK PRESSURE gauge (A4, fig.5) reads LOWER or EQUAL than the nominal pressure listed in the table for the respective tank temperature, IT IS NOT NECESSARY to vent the non-condensable gases from the tank.
5.If the related TANK PRESSURE gauge (A4, fig.5) reads HIGHER than the nominal pressure listed in the table for the respective tank temperature, you should vent the non-condensable gases from the tank. This is accomplished by opening the air purge valve as shown in figures 1,2,3, & 4.
6.Press the STOP keyto exit the reading of the tank temperature
7.Slowlyopen the air purge valve (r,fig.2) counterclockwise (turn ~20 degree)
8.Once opened the air purge valve r, (fig.2) check the tank pressure gauge and the value shown bythe display.
9.Close the air purge valve when the tank pressure comes down to the nominal pressure listed in the table.
Fig.13: Normal R-134° container pressure chart

INSTRUCTIONS MANUAL
VACUUM PHASE
1.Upon completion of the RECOVERY phase it is possible to start the vacuum phase by opening the highand low-pressure valves, pressing the SEL key until the LED corresponding to “EVACUATE” lights, and then pressing GO. The vacuum time can be set as follows. Press SEL until the “EVACUATE” LED lights, then press ENTER; at this point the first digit on the left of the displaywill begin to flash. Press the INCREASE key until the desired digit appears. Likewise, press the ARROW and INCREASE keys to change the other digits. When setting is complete, press the ENTER key to confirm the 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 automatically.
3.Close all the valves and read the vacuum value on pressure gauges (A1) and (A2). Wait for about 2 minutes, and then check that the pressure has not increased during the interval. An increase in pressure signals leaks in the A/C system. Locate and eliminate the leaks; repeat the vacuum phase.
WARNING: Avoid breathing A/C refrigerant and lubricant vapor mist. Exposure 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 equipment). Additional health and safety information may be obtained from additional refrigerant and lubricant manufacturers.
NEW OIL INJECTION
You can inject virgin lubricating oil into the vehicle A/C system at this time. Make certain that the Oil Charge Bottle has sufficient quantity of oil. Cautiously open the Oil Charge valve until the same amount of oil that was recovered in the RECOVERY AND RECYCLING operation is removed from the container and replaced back into the vehicle's A/C system. The oil will be drawn into the vehicle A/C system by the deep vacuum that was obtained while evacuating. The subsequent charging of refrigerant will ensure all of the oil will be charged from the lines and hoses.
RECHARGE AN A/C SYSTEM
WARNING: Always wear safety goggles and hand protection when working with refrigerants. Failure to follow these procedures may result in serious injury. Due to the extreme cold temperatures associated with the use of refrigerants, any contact with the eye can cause blindness and contact with the bare skin can cause burns or frostbite.
CAUTION: When charging a vehicle do not lean on the machine as this may affect the scale readings. Inaccurate weight measurements may result. The vehicle system can be damaged if weights are not measured accurately.
During this phase, the correct refrigerant charge is returned to the vehicle’s A/C system.
1.Press the SEL keyuntil the “RECHARGE” LED lights.
2.Proceed as described below to set the quantity of refrigerant fluid to be charged. Press the ENTER key. The first digit on the left of the display will begin to flash. Press the INCREASE keyuntil the desired value appears. (Digits read in pounds and ounces, or kilograms.) Likewise, press the ARROW and INCREASE keys to change the values of the other digits. Press ENTER when setting is completed to confirm the values. The quantity of fluid required for filling the system is usually reported on a data plate in the engine compartment of the vehicle. If the quantity is not known, consult the relevant system operating and maintenance manuals.
18
INSTRUCTIONS MANUAL
3.Open the highand low-pressure valves (if previouslyclosed) and press the GO key.
4.The machine will stop automatically when the preset quantity has been charged. If the A/C system pressure increases to equal the tank pressure, and the charge is not complete, it will be necessary to draw the remaining refrigerant into the system using the vehicle compressor as outlined below.
5.Close the highand low-pressure valves.
6.Start the vehicle motor and switch on the A/C system, and allow both to run for at least 3 minutes. At this point the system will be at steady state and it will be possible to check the high and low side values on the relative pressure gauges.
7.Disconnect ONLY the high-pressure quick-connect coupling (if necessary, switch the engine off). Then, with the A/C system still running, open the high and low pressure taps to force the A/C system to draw up the refrigerant contained in the hoses.
8.After about 1 (one) minute, disconnect the low-pressure couplings of the VIPER VR6000 from the vehicle A/C system and switch off the engine.
WARNING: When removing hoses from the vehicle, use extreme caution. Wear gloves and eye protection. Take care not to allow refrigerant to enter the eyes. Liquid refrigerant will cause severe burns and/or frostbite to exposed skin, blindness if sprayed into the eyes, and even the possibility of death if inhaled.
RECOVERING THE REFRIGERANT IN THE HOSES.
1.Set the MAIN POWER switch ON and open the high side and low side valves on the front of the machine.
2.Press and hold the SEL keyuntil the LED until the LED corresponding to “RECOVERY” lights; then press GO. At this point the RECOVERY/RECYCLING phase will begin; the “RECOVERY” LED will flash.
3.When all of the refrigerant has been removed from the hoses, the machine will automatically shut off and the lamp in the switch will extinguish. To avoid going through an “unnecessary and time consuming oil dumping phase”, press the stop keyas soon as pressure in low pressure hose reaches zero.
4.Close the High Side Valve and Low Side Valve and turn off the machine’s main power.

The value displayed at this point will correspond to the scale zero value. Press down lightlyon the scale plate; the value should increase. If it does not, replace the charge cell. Press the ENTER key to memorize the value. In this phase, take care that nothing touches the scale plate). Place the reference weight (50 lbs) carefully at the center of the scale plate and check that the displayed value increases accordingly. Press the SEL keyand use the INCREASE & ARROW keys to type in the 4 figures of the reference weight. Press ENTER. The display reading should be the reference weight minus the weight of the empty bottle (tare weight).
Remove the reference weight. Switch off the machine and disconnect from main power supply. Replace the storage tank in its seat on the scale plate. Switch on the MACHINE, taking care not to touch any electrical wires. Check calibration: place a known reference weight on the bottle and check that the displayed availability value increases by the value of the known reference weight ±2%. Remove the reference weight. Switch off the machine and disconnect from main supply. Replace the storage tank locking bolts. Open the red and blue storage tank valves. Replace the rear plastic cover.
NOTE: In order to check the scale calibration the unit must be displaying a positive value for REFRIGERANT AVAILABLE, 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 weight is verified as the known weight.
VACUUM PUMP
Perform the operations listed below on a routine basis in order to ensure good operation of the vacuum pump.
M.1) Oil top-up
M.2) Oil change
M.3) Decontamination
When topping-up or replacing the pump oil, use only VIPER No. 793091 Vacuum Pump Oil.
M.1) Oil top-up
This operation must be performed when the level of the oil falls to less than half on the indicator (4 - Figure 15). To refill the oil, perform the steps listed below in the order given. Refer to Figure 13.
1.Disconnect the VR-6000 from main power supply.
2.Unscrew the filling cap (3).
3.Pour oil into the tank until the oil level is about half on the indicator (4).
4.Replace the oil cap (3) and tighten down.
M.2) Oil change
The vacuum pump oil must be replaced once a season and in any case every time the refrigerant filters are replaced. The oil must also be changed whenever it changes color, becoming dark and turbid, since this is a sign that it has been contaminated and has absorbed humidity. Before beginning the oil change procedure, procure a container of
