Waterbox Locations
IImmppoorrttaanntt:: 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. 89.
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.

NNootteess::
• Refer to the coupling manufacturer’s
guidelines for specific information
concerning proper piping system design
and construction methods for grooved
water piping systems.
• Flexible coupling gaskets require proper
lubrication before installation to provide a
good seal. Refer to the coupling
manufacturer’s guidelines for proper
lubricant type and application.
