RECOVERY PROCEDURES
WARNING!
Always wear safety goggles when working with refrigerant. Use only
authorized refillable refrigerant tanks. Disconnect hoses with extreme
caution!
All hoses may contain refrigerant under pressure. Read and follow all
warnings at the beginning of this manual before operating the unit.
Before beginning recovery, be sure your unit is set up as described in the Set-Up
Instructions. Also be sure there is vacuum pump oil in the vacuum pump.
1. Connect the high and low side hoses to the A/C-R system, as you would normally
connect your manifold gauge set.
2. Be sure both the high and low side valves on the control panel are open. Also be
sure both valves on the tank are open.
3. Plug the unit into the proper voltage outlet, and turn on the MAIN POWER
switch. The display shows either “134a” (which indicates R-134a automotive
refrigerant that uses
1 /
2
” Acme fittings) or “R12” (which indicates all other refriger-
ant types that use 1 /
4
” flare fittings).
