Inspect Water Piping
Refer to piping diagrams prov i ded in the certified drawings , and the piping instructions in the
19XL Installatio n Instructions manual. Inspect the piping to t he cooler and c ondenser. Be su re
that flow dire ctions are correc t and that all piping specific ations have been met.
Piping systems must be properly vented, with no stress on waterbox nozzles and covers.
Water flows through th e c ool er and condenser must meet job requirements. Measu re the
pressure drop across c ool er and across condense r .
Check Optional Pumpout Compressor Water Piping
If the optional storage tank and/or pumpout system are installed, check to ensure the
pumpout condenser wat er has been piped in. Check f or fi eld-supplied shutoff valves and
controls as specifie d in t he job data. Check for refrig erant leaks on field-in stalled piping. See
Figure 27 and Figure 28.
CAUTION CAUTION
!
Water must be within design limits, clean, and treated to ensure proper machine
performance and reduce the potential of tubing da mag e due to corrosion, scal-
ing, or erosion. Carri er assumes no responsibi lity for chiller damage resu lting
from untreated or improperly treated water.
