7.Machine will run automatically until correct amount of refrigerant is removed.

8.When the pressure of both the HP and LP system are near “0”, the system will automatically reset to run approximately 1 minute longer. After that, there is a 20 second oil drain period. The machine will then automatically shut off.

9.Machine will shut off and alarm will sound to signal process is completed.

Understanding and resolving problems during the recovery process

1.If during the recovery process the pressure exceeds safe limits, the refrigerant bottle be- comes full, or no refrigerant is recovered for a minute, the system will stop automatically. 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.

2.If the system pressure exceeds 240 PSI, the machine will shut down an alarm will sound, and the “HP / Bottle Full” light will come on. Reduce the pressure to below 180 PSI, then press the “Start / Stop” Key to restart the process.

3.If the Refrigerant Bottle becomes full during the recovery process, the operation will shut down, an alarm will sound, and the “HP / Bottle Full” light will come on. Remove some refrigerant from the bottle before restarting the process.

4.If weight of refrigerant tank does not increase for a minute, it indicates that no refrig- erant is being recovered. This may mean the auto A/C system is empty, the HP or LP valve is closed, a hose is blocked, or other problem. The process will shut down, and an alarm will sound. Resolve the problem before restarting the process.

5.Do not operate machine more than 10 times in an hour. Doing so may overheat compressor. If overheated, machine will automatically shut down and alarm will sound. Allow machine to rest for at least 5 minutes before attempting restart.

Vacuuming the System

1.After recovering the refrigerant in the auto A/C system, you must vacuum the system to remove all remaining contaminants.

2.The LP and HP hoses are still connected from running the Recovery Process. The 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.

3.Press “Vacuumize” Key on the Control Panel. The LCD Display will show the default 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.

4.Press “Start / Stop” Key on the Control Panel to begin the Vacuuming Process.
