piping will prevent condensation from forming on the
pipe and dripping on the floor.
Notes:
• Trane does not provide insulation on the
economizing piping package. The 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.
8. Field pipe the drain lines of the waterside economizer
and water-source heat pump. Both the WSE and unit
condensate drains must be separately trapped for
proper handling of condensation (see
). Both Vertical and Horizontal units will be piped similar
to each other. The drain connection is located on the
bottom side of the economizing coil.

Waterside Economizer Installation for
Vertical 0.5 to 5 Ton Units
The following steps were sequenced to aid in the
installation and pairing of a water side economizer to a 0.5
to 5 ton vertical 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.
Figure 70. 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.

3. Attach the filter brackets to the waterside economizer
using five screws. Install the air filter.
