PROBLEM: I turned a 30 lb. cylinder of new refrigerant upside down to fill the Charging Cylinder with
liquid. The Charging Cylinder didn't fill and now the TC2670 won't recover from an A/C
system.
SOLUTION: The TC2670 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
TC2670 WILL OVERFILL WITH LIQUID REFRIGERANT.
THIS OVER FILLS THE SUCTION ACCUMULATOR
WITH LIQUID.
FROST ON THE OIL DRAIN ON THE REAR OF THE
TC2670 IS A GOOD INDICATION OF THIS
OCCURRENCE.
THIS SYMPTOM IS CAUSE FOR CONCERN AS LIQUID
REFRIGERANT WILL BE FORCED INTO THE
COMPRESSOR.
THIS CAN DESTROY THE COMPRESSOR AND WILL
VOID THE WARRANTY.
The safest method to remove the excess liquid which has collected in the Suction
Accumulator is to drain it from the Oil Drain on the back of the TC2670 as follows:
Draw a deep vacuum (25 to 29 In. Hg.) on an empty cylinder 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 TC2670 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.
