Microprocessor: Controls functions; prompts lead you through programming and also signal time to change the filter-drier, vacuum pump oil and compressor oil. Float Chamber: Automatically adjusts from liquid to vapor for most efficient recovery. Electronic Scale: Makes it simple to recharge to factory specifications; also weighs recovered refrigerant and provides tank overfill protection. Cool-Tech Vacuum Pump: 6 CFM has the capacity to thoroughly evacuate system, readying it for recharging. Versatility for many types of systems! Lockout Panel: Prevents mixing of refrigerants; slides to one side for 1/4 in. fittings and to the other for 1/2 in. Acme fittings.
