Waterside Economizer Installation
Note:
GEH ½-5 and EXH 1½-6 ton units.
The following steps were sequenced to aid in the
installation and mating of a water side economizer to a
water-source heat pump (GEH ½-5 ton) and (EXH 1½-5
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 head screws. This panel
is shipped loose with the water-source heat pump but
must be field installed to the unit.
4. Attach the water side economizing unit to the ducted
panel of the water-source heat pump with 10-factory
provided 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.
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 (1) 2-
position valve’s threaded connection (2) water-out
threaded connection of the water-source heat pump.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow codes could result in death or serious injury.
