RECOVER/RECYCLE
1. Setup the AC880 as shown on Page 4 and then turn the Main Power Switch
ON.
2. Attach the Red and Blue Hoses to the A/C System per the vehicle
manufacturer's instructions, open the Red and Blue Hose Valves.
3. Using the Keypad, press the “Up Arrow” key one time to display “WEIGHT=
XX.X LB” “RECYCLE? 5” and press the ENTER key. The Display will read
“RECYCLE HOLD” “TIME XX MIN 5”.
The Recycle Hold Time is the amount of time that the AC880 waits for “out-
gassing” or for the pressure in the A/C System being recovered to rise
enough to automatically restart the recovery process. The minimum value is
two minutes. The value entered is stored in memory and comes up as the
default value the next time the procedure is used.
4. Press the “Up Arrow” key to change the value of the field. Press the “Right
Arrow” key to change to a different field. Press the ENTER key to accept the
value. The Display will then read “CHECK HOSES” “START? 5”.
5. Press the ENTER key to start recovering and recycling with the AC880.
The Display will read the “WEIGHT= XX.X LB” “COMPRESSOR ON”. The
AC880 will recover and recycle refrigerant from the A/C System and
automatically cycle OFF when a vacuum is sensed. This vacuum level can
be seen on the Low Pressure Gauge. The Display will read “WEIGHT= XX.X
LB” “COMPRESSOR OFF”
A small quantity of refrigerant will probably remain in the A/C System as
observed by an increasing pressure on the Low Pressure Gauge. The AC880
will automatically cycle ON to continue recovering refrigerant if pressure rises
to a preset level. This automatic cycling will repeat resetting the Recycle Hold
Timer each time. When the AC880 remains OFF for the duration of the
Recycle Hold Timer value entered in Step 4 the Display will read “AMOUNT
RECYCLED=” “XX.X LB 5” from the A/C System and the Attention Light will
turn ON.
6. Close the Red and Blue Hose Valves and disconnect the hoses from the A/C
System.
7. Press the ENTER key. The Display will read “DRAIN RECOVERED OIL
NOW!”. Drain any recovered oil using the Drain Recovered Oil procedure on
Page 7.
8. Press the ENTER key to return to the Main Menu.
* This screen will display if there is an internal fault. Please contact RTI
Technical Support. Turn the AC880 Main Power Switch OFF.
** This screen will display when the Charging Cylinder fills to capacity,
approximately 39.5 lbs (18 Kg.) If this occurs, the Weight can be lowered
using the Charging procedure on Page 9 before the AC880 can be used
to recover more refrigerant. Press the ENTER key to return to the Main
Menu.
