Water Piping
For applications that include an
“infinite source” or “multiple-use”,
cooling condenser water supply,
install a valved bypass “leg”
(optional) between the supply and
return pipes; see Figure 4. This
valved bypass allows the operator to
short-circuit water flow through the
cooling condenser when the supply
water temperature is too low.
See “Condenser Water Temperature
Control for CenTraVac
®
Centrifugal
Chiller Systems” Engineering
Bulletin (CTV-PRB006-EN) for
additional application information.
Important: System refrigerant
pressure differential must be
maintained above 5 PSID [34 kPa] at
all times. Failure to do so could
result in operating problems.
Note: Whenever a CVHE, CVHF
and CVHG unit is equipped with an
auxiliary condenser, use a bypass
valve system to avoid circulating
water through the auxiliary shell
during unit shutdown.
Water Box Locations
If necessary, the non-marine-style
water boxes on each shell whether
evaporator or condenser can be
switched end-for-end to obtain the
desired piping arrangement. Contact
Trane LBU Marketing for switching
of marine-style boxes.
Important: Do not exchange
positions of marine-style water
boxes. Failure to follow this
recommendation could alter
designed water flow piping
configuration and prevent proper
unit operation.
WARNING
Heavy Objects!
Use only shoulder pattern eyebolts
which are properly seated for lifting
the water box. Failure to use the
proper lifting procedures could
result in death or serious injury.
To accommodate lifting apparatus, a
nut is welded to each evaporator
water box to enable attachment of a
3/4" [19 mm] eyebolt (field supplied).
Condenser water boxes are
provided with 1/2" [13 mm] tapped
holes that allow installation of the
eyebolt included in the unit’s loose
parts-box.
If the water boxes on any of the
shells are exchanged end-for-end, be
sure to reinstall them right side up to
maintain the correct baffle
arrangements. Use a new gasket
with each water box cover.
