Viper VR-6000 owner manual Recovering The Refrigerant In The Hoses

INSTRUCTIONS MANUAL

3.Open the high- and 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 high- and 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 VR- 6000 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.
