3. Open the high- and low-press ure valves (ifpreviouslyclosed) and press the GOkey.

4. The m achine will stop autom atically when the preset quantity has been charged. If the

A/C system press ure increases to equal the tank pressure, and the charge is not

complete, it will be necess ary to draw the remaining refrigerant into the system using

the vehicle compressor as outlined below.

5. Close the high- and low-press ure valves.

6. Start the vehicle motor and s w itch on the A/C system,and allow both to run for atleast 3

minutes. Atthis point the s ystem will be at s teady state and it will be possible to check

the high and low s ide values on the relative pressure gauges.

7. Disconnect ONLY the high-press ure 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 refrigerantcontained in the hoses .

8. After about 1 (one) minute, disconnect the low-press ure couplings of the VIPER VR-

6000 from the vehicle A/C s ystem and switch offthe engine.

W ARNING: W hen removing hoses from the vehicle, use extreme caution. W ear gloves

and eye protection. Tak e car e not to allow refrigerant to ent er the eye s. Liquid refrigerant

will cause sev ere burns and/or frostbite to ex posed skin, blindne ss if sprayed into the

eyes, and even the possibility of death if inhaled.

RECO VERING THE REFRIGERANT IN THE HO SES.

2. Press and hold the SEL key until 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 flas h.

3. When all of the refrigerant has been removed from the hoses, the machine will

automatically shut offand the l amp in the switch will extinguish.To avoid going through

an “unnecessary and time consum ing oil dumping phase”,press the stop keyas soon

as press ure in low press ure hose reaches zero.
