PROBLEMS ?
Refer to Page 18 should problems be encountered using the Fill Cylinder procedure.
Pressure differential between the cylinder of new refrigerant and the internal AC880 charge cylinder greatly affect the efficiency and speed of the Fill Charge Cylinder procedure.
FILL CHARGE CYLINDER
N N N EXTREMELY IMPORTANT N N N
Always connect Yellow Hose (15) to Cylinder (14) first and then connect other end of hose with
Note: For large capacity or multiple A/C Systems where recharge will NOT be done between successive recoveries, it may be desirable to skip this procedure.
1.Set up the AC880 as shown on Page 4 and then turn the Main Power Switch ON. An adapter is provided with the AC880 (R134a) which permits the Yellow Hose (15) to be attached to the 1/4 SAE Flare fitting that is on some cylinders of R134a refrigerant.
Note: The AC880 uses 15.4 lbs (7 Kg) of refrigerant when Filling the first time. If the Refrigerant Cylinder (14) is emptied, the AC880 will appear to stop filling (the Weight will stop rising) and will stay in this condition until the RESET key is pressed.
2.Using the Keypad, press the “Up Arrow” key four times to display “WEIGHT= XX.X LB” “FILL CYLINDER? #” and press the ENTER key. The Display will read “CHECK HOSES” “START? #”.
3.Open the LIQUID Valve on the Refrigerant Cylinder (14) connected to the Fill Port (13) with the Yellow Hose (15).
4.Press the ENTER key when ready to start filling the AC880.
The Display will read “WEIGHT=XX.X LB” “COMPRESSOR ON”. When the level is approximately 13 lbs (6 kg), 75 percent of the full capacity, the AC880 will turn OFF, the Display will read “FILL COMPLETE” “FILLED= XX.X LB #” (the amount of refrigerant removed from the cylinder) and the Attention Light will turn ON. Close the Liquid Valve on the Refrigerant Cylinder.
Note: Press the RESET button on the Keypad to stop the Fill Cylinder procedure at any time.
5.Press the ENTER key to return to the Main Menu.
*While filling the Charging Cylinder, this screen will display periodically concurrent with the Attention Light turning ON. This is normal and nothing to be concerned about. The screen should revert to normal after a few seconds.
**This screen will display when the Charging Cylinder fills to capacity, approximately 17.5 lbs (8 Kg). If this occurs, the weight can be lowered using the Charge procedure on Page 9 before the AC880 can be used to recover more refrigerant. Press the ENTER key to return to the Main Menu.
Note: The AC880 Charging Cylinder can also be filled from the GAS or VAPOR side of a cylinder by following the Recover/Recycle procedure on Page 6.
Note: The AC880 will use 1.1 lb (0.5 Kg) more refrigerant than the displayed value the very first time it is used or after performing a Calibration Procedure in order to prime the internal components.
Note: The Yellow Hose (15) can be removed from the Fill Port (13) and connected to either the Blue or Red Hose connection port on the rear of the AC880 to recover the refrigerant left in the Yellow Hose (15) using the Recover/Recycle procedure on Page 6.
