capable of reading the actual entering water
temperature regardless of the economizer’s on or off
situation.
12. Insulate the thermistor with tubing insulation.
13. Tie wrap each end of the tubing insulation to prevent
air filtration.The tie wraps and insulation are located in
a bag and shipped inside of the unit.
14. Thread the factory wire harness through the low
voltage hole of the heat pump to the 3-way valve’s wire
harness.
15. Connect the factory installed wire harness to the to the
wire harness supplied with the 3-way valve (see
Table 45, p. 66
).
16. Bundle excess valve wire, and wire tie the bundle
neatly.
17. Install control side service panel to the heat pump.
18. Install the unit filter frame to the economizing inlet.
19. Insulate the economizing piping package with field
supplied pipe insulation. Insulating the piping will help
stop condensation from forming on the pipe.
Notes:
•
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 field installed.
20. Install waterside service panel to the heat pump.
21. The economizer condensate line must be trapped prior
to the unit’s drain line. This helps prevent air from
being sucked through the drain line causing
condensate to spit or build-up in the economizer or unit
drain pans. Field pipe the drain lines of the waterside
economizer and water-source heat pump together
prior to installing a condensate trap. See page
“Condensate Drain Connection,” p. 57
for proper
trapping of condensation.
