Water Piping Connections
All standard units use grooved-pipe connections. These
are grooved-end NSP (Victaulic style) pipe connections.
Flanged connections are optional.
Piping joined using grooved type couplings, like all types
of piping system s, requires proper support to carry the
w eight of pipes and equipm ent. The support m ethods
used m ust elim inate undue stresses on joints, piping and
other com ponents; allow m ovem ent w here required, and
provide for any other special requirem ents (i.e., drainage,
etc.).
N ot e: Plug-type sensor extension cables are available for
purchase from Trane Parts Service if needed. These
sensor extension cables m ay be necessary if the
waterboxes are changed or if the tem perature
sensors are m oved out into the unit piping for
better m ixed tem perature readings.
Waterbox Locations
If necessary, the non-m arine-style waterboxes on each
shell w hether evaporator or condenser can be sw itched
end-for-end to obtain the desired piping arrangem ent.
If rem oval of waterboxes is necessary, refer to “ Waterbox
Rem oval and Installation,” p. 98 .
If the waterboxes on any of the shells are exchanged end-
for-end, be sure to reinstall them right side up to m aintain
the correct baffle arrangem ents. Use a new gasket w ith
each waterbox cover.
