4. Attach the water side economizing unit to the ducted
panel of the water-source heat pump with 10-factory
provided screws.The economizing package fits to the
outside of the of the water-source heat pump. Trane
recommends the mating of the systems be made via 3-
screws spaced evenly across the top, 3-screws spaced
evenly across the bottom (installed immediately after
hanging the unit), and 2-screws on each side.
Note:
Waterside economizer option is configured for
right return. Left return requires additional field
piping.
5. Install the 18-inch steel braided hose between the
upper most piping connection of the economizer, and
the water-in of the heat pump. The hose is shipped
loose with the water-side economizer.
6. Install the SUPPLY and RETURN hoses to the:
a. 2-position valve’s threaded connection
b. water-out threaded connection of the water-source
heat pump
7.
Verify the control board for the water side economizer
is located at the back of the control box. The
temperature rating of this board is factory set to 55ºF.
For units with boilerless (electric heat) control and
water side economizer, the boilerless control board is
factory set to 45ºF.
8. Thread the bulb and wire through the low voltage hole
of the water-source heat pump. See
