The following steps were sequenced
to aid in the installation and mating
of a water side economizer to a
water-source heat pump (GEH 1/2 to
5 ton).
1.
Remove the control side service
panel of the water-source heat
pump unit.
2.
Remove rubber isolation
grommets from the return-air
section. Place them in a
convenient location.
3.
Attach ducted panel to the water-
source heat pump unit with six
factory provided Torx® head
screws. This panel is shipped
loose with the water-source heat
pump but must be field installed
to the unit.

Step 3
4.
Attach the water side
economizing unit to the ducted
panel of the water-source heat
pump with 10-factory provided
Torx® head 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.
Figure 71.
Step 4
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.
