Inspect Water Piping
Refer to piping diagrams provided in the certified drawings, and the piping instructions in the
19XL Installation Instructions manual. Inspect the piping to the cooler and condenser. Be sure
that flow directions are correct and that all piping specifications have been met.
Piping systems must be properly vented, with no stress on waterbox nozzles and covers.
Water flows through the cooler and condenser must meet job requirements. Measure the
pressure drop across cooler and across condenser.
Check Optional Pumpout Compressor Water Piping
If the optional storage tank and/or pumpout system are installed, check to ensure the
pumpout condenser water has been piped in. Check for field-supplied shutoff valves and
controls as specified in the job data. Check for refrigerant leaks on field-installed piping. See
Figure 27 and Figure 28.

Water must be within design limits, clean, and treated to ensure proper machine
performance and reduce the potential of tubing damage due to corrosion, scal-
ing, or erosion. Carrier assumes no responsibility for chiller damage resulting
from untreated or improperly treated water.
