Because of its high stability and accuracy, the 68860 is ideal for automotive, commer-
cial, and residential A/C refrigerant charging and recovery. Its high resolution also
allows accurate critical charging of small refrigeration systems such as commercial
freezers. To use the 68860 for refrigerant charging, perform the following steps:
1. Press the “UNITS” key to set the desired display units.
2. If desired, set up the Tank Capacity Mode as described in the Tank Capacity
Mode section. This will allow you to know at any time the percent of refrigerant
remaining in the refrigerant cylinder.
3. Carefully set the refrigerant cylinder on the weighing platform.
4. Attach the cylinder to the charging manifold via a utility hose. Open the cylinder
valve and purge air from the hose.
5. Program the desired refrigerant charge weight as described in the Programming
section. Activate the program by pressing the “RUN/STOP” key.
6. Open the manifold valve(s).
7. The display will indicate the weight charged as negative, indicating refrigerant is
being removed from the charging cylinder.
8. If the refrigerant cylinder empties while charging:
Close all valves.
Press the “HOLD” key to “freeze” the display (as described in the Hold
Mode Section).
Replace the empty refrigerant cylinder with a full one. Attach and purge hoses.
