WARNING
Wear safety goggles when working with refrigerant. Read and follow
all warnings at the beginning of this manual before operating the unit.
1. Connect the power cord to the back of the unit, and plug it into the correct
voltage outlet.
2. Turn on the MAIN POWER and, if necessary, empty the oil drain bottle
located on the right hand side of the unit.
3. Press the
RECOVER
button.
4. If 150 pounds (68 kg) or more of refrigerant has been recovered since the last
filter-drier change, the display reads FILTER WEIGHT XXX lb (XX kg).
Press
START.
NOTE: Refer to the filter change procedure on page 19 of this manual for details
about replacing the filter.
5. Connect the high and low side hoses to the A/C system, and open the coupler
valves.
6. Put the Low Side Valve in the Recover/Vacuum position. Put the High Side
Valve in the Recover/Vacuum position. Press
START
to continue.
7. If the system pressure is below 25 psi, the display reads: LOW SYSTEM
PRESSURE until the pressure increases or the
START
button is pressed. You
may press
STOP
to exit at this point.
8. If the unit has refrigerant in the low-side plumbing, it begins the clearing
process and displays CLEARING IN PROGRESS. If you wish to skip the
clearing operation or stop the clearing prematurely, press the
