Depending on the reason for shut down, an alarm may sound, and the “HP/Bottle Full”
indicator may light. If this happens, resolve the problem before restarting the process.

sound. Allow machine to rest for at least 5 minutes before attempting restart.
Vacuuming the System
After recovering the refrigerant in the auto A/C system, you must vacuum the system 1.
to remove all remaining contaminants.
The LP and HP hoses are still connected from running the Recovery Process. The 2.
HP and LP Valves are open on the Control Panel. NOTE: The Vacuuming Process
will not run if the system pressure is above 35 PSI. The recovery process must be
run to reduce system pressure.
Press “Vacuumize” Key on the Control Panel. The LCD Display will show the default 3.
time preset for the vacuum process. Using the “+” Key adjust the time as required.
Typically, vacuuming should proceed for 20-30 minutes. Newer or more regularly
serviced systems can run 20 minutes. Dirtier systems should run 30 minutes.
Press “Start / Stop” Key on the Control Panel to begin the Vacuuming Process. 4.
