Combines simple operation with superior accuracy. The Cool-Tech 34788 recovers, recycles, evacuates, leak tests, and recharges R-134a quickly and accurately. Automatic operation means less attention is needed!

• Automatic Function — With this new option, you can program the unit to
  recover, vacuum, leak test, charge, and then walk away without having to operate panel valves.
• Vacuum Leak Test — Will monitor the vacuum level after an evacuation, and
  inform the technician of a possible leak in the vehicle’s A/C system.
• Automatic Refrigerant Refill — With this latest advance, you never have to
  stop in the middle of a job to change refrigerant tanks. The unit maintains a user
  selectable amount of refrigerant in an internal vessel, and signals when it’s time
  to change the supply tank, so no monitoring is required.
• Automatic Air Purge — Eliminates damaging air without any monitoring of
  gauges or opening of valves.
• Automatic Oil Drain — The unit automatically drains system oil captured during
  recovery, and the display reminds you to empty the bottle. Graduations on the
  container clearly show you how much oil needs to be replaced.
• Refrigerant Charging — Has never been this easy. Select a charge mode from
  either the high side, low side, or both. Accuracy features eliminate guesswork!
• Refrigerant Management Systems—New and improved, system displays
  refrigerant use and monitors remaining fi lter life. Prompts appear when 1/3 of
  filter life remains.
• Vacuum Function — Defaults to 15 minutes, but is programmable up to 99
  minutes. Remaining vacuum time is displayed on the screen.

• No more guessing how much oil to add back when replacing components.
  
• Import charge capacity directly to charge mode.
