Liquid Sampling

Liquid sampling is an option that is exclusive to the Ultima ID Pro™. It permits the user to
flash liquid into vapor for introduction into the analyzer. To use the liquid sampling assembly,
follow these eight steps:
1) Inspect the High Pressure Liquid Sample Trap Assembly and ensure that the
plunger is completely depressed. Assemble the High Side Liquid Sample Hose as
shown on page 1-12 of this manual.
2) Connect the appropriate end of the hose to the instrument and the opposite end
of the liquid sampling assembly to the High Side Liquid port of the system or
cylinder. Affix the High Pressure Liquid Sample Trap Assembly vertically to a
tank with the magnet.
3) Open the high side valve of the cylinder. The liquid sample will exit the tank and
flash to vapor in the hose assembly. As the liquid is flashed, the plunger on the
High Pressure Liquid Sample Trap Assembly will begin to rise and the flashed
refrigerant sample will travel into the analyzer.
4) Wait for the plunger on the High Pressure Liquid Sample Trap Assembly to
expand past the outlet port.
5) Press 'TEST' on the Analyzer (Figure 7).
6) Upon completion of the test, close the valve on the cylinder, disconnect the hose
from the inlet of the High Pressure Liquid Sample Trap Assembly, and depress
the plunger to expel any trapped oil.
7) Inspect the hose for signs of oil and replace the Brass Sample Hose Restrictor if
necessary.
8) Disconnect the hose from the Ultima ID Pro™
NOTE:
Liquid sampling will likely clog the Brass Sample Hose Restrictor much faster than
Vapor Sampling. If the Restrictor becomes clogged and the analyzer continuously displays
"Non-Condensable" or "Unknown Refrigerant" readings you will need to replace the clogged
Restrictor with a new one. To avoid oil or liquid contamination from entering the analyzer,
have a designated vapor and liquid Brass Sample Hose Restrictor for each form of testing.
