Step 15
16. Insulate the economizing piping package and the
supply/return/by-pass hoses (3-hoses) via field
provided pipe insulation. Insulating the piping will
stop condensation from forming on the pipe and
dripping onto the ceiling tiles.

ess::
•
Trane does not provide insulation on the
economizing piping package. This insulation
must be field provided and field installed.
•
Trane does not provide condensate
overflow protection of the waterside
economizer. This must be field provided and
installed.
17. Install filter rack (top and bottom) to the
economizing package. The filter rack is located in
the unit’s packaging along with the filter.
18. Hang unit. See
for hanging of the
packaged unit. Bottom screws referenced in Step 4
must be installed at this time.
19. Field pipe the drain lines of the waterside
economizer and water-source heat pump together
prior to installing a condensate trap (see
“Condensate Drain Connection,” p. 30
)for proper
trapping of condensation.

Step 19
Waterside Economizer Installation for
Vertical Units
The following steps were sequenced to aid in the
installation and pairing of a water side economizer to a
EXV and DXV water source heat pump.
1. Remove the filter bracket from the unit. It is secured
by five screws: three on top (circled) and two on the
bottom (not shown). Do not discard the filter
brackets.

Step 1
2. Mount the waterside economizer to the unit. It is
secured to the unit using the five engagement holes
that were used for the filter brackets: three on top
and two on the bottom.
