Waterbox Locations
Important: Do NOT exchange positions of marine-style
waterboxes. Proper unit operation and proper
water flow could be affected by repositioning
marine-style waterboxes. Contact
CenTraVac™ Chiller Technical Service for
more information.
If necessary, the non-marine-style waterboxes on each
shell—whether evaporator or condenser—can be switched
end-for-end to obtain the desired piping arrangement.
If removal of waterboxes is necessary, refer to “Waterbox
Removal and Installation,” p. 94.
If the waterboxes 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 waterbox cover.
Grooved Pipe Coupling
A customer-supplied, standard flexible grooved pipe
coupling (Victaulic
®
Style 77 or equivalent) should be used
to complete the Victaulic
®
connection for both 150 psig
(1034.2 kPaG) and 300 psig (2068.4 kPaG) waterboxes.
When a flexible coupling such as this is installed at the
waterbox connections, other flexible piping connectors (i.e.,
braided-steel, elastomeric arch, etc.) are not usually
required to attenuate vibration and/or prevent stress on the
connections.
