• Fully-Automatic Function: Program to recover, vacuum, leak test, and charge
  without operating panel valves.
  
• Automatic Dye Inject: Gives the user the ability to use the machine to inject UV dye into a vehicle's A/C system.
  
• Automatic Oil Measure & Inject: The machine will automatically determine how much
  lubrication oil needs to be injected back into the A/C system based on how much oil
  was taken out during recovery.
  
• A/C System Flush: Flushes a vehicle's A/C system with refrigerant, eliminating a residual oil or other liquid.
  
• Save & Print before and after service data: Allows the user to store before and after service information by vehicle, and print this information to provide to a customer.
  
• Indicator light and notification alarm: Notifies the user when service is complete, or if a problem has occurred
  

• Recovers 20 percent More Refrigerant!
• Charge Accuracy +/- 1/2 Ounce
• Control panel offers flat storage feature when not in use
• Two large tool storage areas
• Change between traditional & hybrid vehicle systems without fear of cross
  contamination with improved oil injection
• New 2X larger display makes the 34988 easier than ever to use
• Built-in storage for extra filter
• On-board storage for compressor oils

Combines simple operation with superior accuracy. The Cool-Tech 34988 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 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.
  
• Vacuum Function — Defaults to 15 minutes, but is programmable up to 99 minutes. Remaining vacuum time is displayed on the screen.
  
• Oil Inject: Less than 1% cross-contamination.
  
• Refrigerant & Oil Database: For North American market vehicles 1994 - 2008.
  
• Automatic Air Purge: Eliminates damaging air without monitoring gauges or opening valves.
  
• Automatic Refrigerant Refill: Maintains a user-selectable amount of refrigerant in an internal vessel and signals when it's time to change supply tank; no monitoring required.
  
• Display: Multilingual
  
• Refrigerant Charging: Select a charge mode from high-side, low-side, or both.
  
• Refrigerant Management System: Displays refrigerant use and monitors remaining filter life. Prompts appear when 1/3 of filter life remains.
