NOTICE
Equipment Damage!
If using any commercial flushing/cleaning solution,
construct a temporary bypass around the unit to
prevent damage to internal components of the
evaporator/condenser. Trane assumes no responsibility
for equipment damage caused by flushing/cleaning
solutions or water-born debris.
Make water piping connections to the evaporator and
condenser. Isolate and support piping to prevent stress on
the unit. Construct piping according to local and national
codes. Insulate and flush piping before connecting to unit.
Use grooved pipe connectors for all water piping
connections. Evaporator and condenser water inlet and
outlet sizes and locations are shown by the unit submittals.
The designation in the tables corresponds to the
compressor frame code followed by the evaporator shell

Reversing Waterboxes
All water boxes may be reversed end-for-end. See
"Maintenance Procedures," p. 69
removal instructions.
Remove sensors from wells before removing waterbox.
Do not rotate water boxes. See
Figure 16, p. 32
for correct orientation of the water inlet
and outlet.
Complete the water box switch and replace sensors.
Notes:
•
If water boxes are reversed, be sure to properly rewire
water temperature sensors in control panel.
•
Be certain to replace water boxes right-side-up to
maintain proper baffle orientation. Use new o-rings.
