Operating Instructions
WARNING
Wear safety goggles when working with refrigerants. Read and
follow all warnings at the beginning of this manual before oper-
ating this machine.
Connecting hoses to the wrong ports may cause personal injury
and/or damage to the equipment. Check your vehicle’s A/C
system operating manual for the correct hookup.
Handle battery connection cables with extreme caution — batter-
ies generate explosive gases during normal battery operation.
Working in the vicinity of a lead-acid or other automotive battery
is dangerous. Wear complete eye protection. NEVER smoke or
allow a spark or flame in the vicinity of a battery.
1. Run the vehicle’s A/C system for a few minutes before starting the recovery
process. Tests show more refrigerant is recovered if this action is taken. Turn the
system off before proceeding.
2. Connect one of the station’s blue recovery hoses (8) to the low-side service port
on the vehicle’s air conditioning system. The other blue recovery hose should not
be connected to the vehicle’s system, but should remain connected to the back of
the recovery station.
3. Open the tank valve with the 3 /
8
" hose connected to it. Open the 3 /
8
" hose valve.
4. Turn the control panel valve (13) to START . This equalizes the pressure on both
sides of the compressor, allowing easier starts.
5. Connect a compressed air line (120 psi minimum; 200 psi maximum) to the air
inlet on the regulator (6) on the back of the station.
6. Connect the red power lead to the “+” (positive) post of the vehicle’s battery, or to
another 12-volt power source. Then connect the black power lead to an engine
ground,
not the battery “-” (negative) terminal.
The compressor should start idling, and the yellow power LED and the green tank
level LED will illuminate. If the green LED does not illuminate, the tank is full or
the float cable is disconnected.
7. Turn the control panel valve (13) to RECOVER . There should be a change in the
sound of the compressor. The inlet pressure gauge (11) should show a drop in
pressure, and the tank pressure gauge (12) should rise.
8. When the inlet pressure reaches a vacuum, disconnect the air line. Wait five (5)
minutes. If the inlet pressure rises above 0 (zero) psi, repeat Steps 4 through 8.
