TROUBLESHOOTING FILL CYLINDER PROCEDURE

1)The cylinder of new refrigerant should be at ambient temperature or greater for best performance of the Fill Cylinder procedure. Make sure the cylinder was not recently moved from an air-conditioned storage room to a warm work area. Place the cylinder on a block of wood if necessary to elevate it from a cool concrete floor. Application of a heat belt to the cylinder will greatly enhance the speed.

2)Verify that the cylinder of new refrigerant (14) is up-side-down as shown in the figure on page 4 and that the cylinder valve is open.

3)If filling the Charge Cylinder from a DOT Cylinder, make sure the hose is connected to the liquid port and the DOT Cylinder is right-side-up.

4)If the yellow hose (15) was connected to the Fill Port (13) the first time the AC880 was used, there may be excessive air in the AC880 Charge Cylinder. At least 4 lbs. of refrigerant must be recovered/recycled into the AC880 Charge Cylinder following the Recover/Recycle procedure on Page 6. During this process, the air in the AC880 Charge Cylinder will be automatically purged.

5)Verify that the cylinder of new refrigerant has liquid refrigerant in it by shaking the cylinder or weighing the contents. A minimum of 4 lbs. of liquid is required.

6) Verify that the Yellow Hose (15) is connected correctly from the Cylinder (14) to the Fill Port (13). On an R12 AC880, the Fill Port is equipped with a valve core so a depressor must be present in the hose end (see figure). The Yellow Hose (15) has a shut-off valve on one end (instead of an anti-blowback valve) which must be connected to the Fill Port (13). The depressor in the hose may be adjustable, so extend the depth of the depressor by using needle-nose pliers.

7) Remove the valve core from the Fill Port (13) using a valve core remover.

There may be a machine fault if the above steps do not result in a successful increase of weight shown on the display after running the Fill Cylinder procedure for a minimum of 15 minutes.
