PROBLEM: I turned a 30 lb. cylinder of new refrigerant upside down to fill the Charging
Cylin d er wi th liquid. The Charg ing Cylinder didn't fill and now the AC800 won 't
recover from an A/C system.
SOLUTION: The AC800 has been overloaded with liquid refrigerant (see Safety Precaution
Section at the beginning of this manual).
... WARNING ...
IF A CYLINDER IS TURNED UP-SIDE-DOWN, THE
AC800 WILL OVERFILL WITH LIQUID
REFRIGERANT. THIS OVER FILLS THE SUCTION
ACCUMULATOR WITH LIQUID.
FROST ON THE OIL DRAIN ON THE REAR OF THE
AC800 IS A GOOD INDICATION OF THIS
OCCURRENCE.
THIS SYMPTOM IS CAUSE FOR CONCERN AS LIQUID
REFRIGERANT WILL BE FORCED INTO THE
COMPRESSOR.
THIS C AN DEST ROY THE COMPRESS OR AND WILL
VOID THE WARRANTY.
The safest method to remove the excess liquid which has collected in the Suction
Accumulato r is t o drain it from the Oil Drain on the back of the AC800 as follows:
Draw a deep vacuum (25 to 29 I n. Hg .) on an emp t y cy linder and connect it to the
Oil Drain Valve. Open the cylinder valve and the Oil Drain valve.
Close the valves and disconnect the cylinder after the liquid has been drawn into the
cylinder. This refrigerant can now be recycled by the AC800 following normal
recycling procedures.
If the above suggested solutions do not solve the problem, call the phone number shown on the
Serial Label on the rear of the machine and one of our technicians will help diagnose the cause.
Please have the Serial Number available for reference.
