also see submittal. It is recommended that larger size
economizers be lifted using overhead rigging.
2. If the unit has insulation, remove the insulation and
loosen the bolts on the condenser liquid line flange.
See Figure 17, p. 28. Do not remove the bolts at this
time. Cut the motor cooling drain line(s) if present and
cut entering and leaving 5/8 inch OD copper oil cooler
lines. Refer to Figure 17, p.

NOTICE
Angle Valves Damage!
Rigging, handling, and placing chiller components
on uneven surfaces can cause damage to angle
valves.
Remove angle valves to avoid breakage during
handling if it is necessary to remove the
economizer.
Note: Take care to avoid damage to angle valves
during handling and transfer of economizer.
3. Loosen the bolts on the evaporator liquid line flange.
This connection is near the bottom of the evaporator.
See Figure 17, p. 28. Do not remove the bolts at this
time.
4. Economizers are connected to the condenser shell via
a bolted flange. See Figure 22, p.
at this flanged connection.
5. Loosen the economizer vent pipe bolts that secure the
vent pipes to the compressor interstage castings
(unless the compressor has already been removed to
gain vertical clearance.)
6. Secure economizer with appropriate rigging.
7. Remove the bolts from the condenser and evaporator
liquid line connection flanges. Adjust the floor jack as
necessary to support the weight of the economizer.
8. Remove the economizer vent pipe flange bolts to
loosen the economizer. When the bolts are free, back
the economizer away from the chiller. The economizer

31. Remove the bolts
may tend to rotate off the jack towards the chiller. Be
prepared to offset the rotation.
9. Remove the economizer orifice plates and mark them
so they are reinstalled in their original position. The
orifice with the greatest number of holes is to be
located between the economizer and the evaporator.
The orifice with fewer holes is to be located between
the condenser and economizer.
10. Move the economizer away from the chiller and set it
on a pallet. Cover all openings to prevent the entry of
foreign material into the economizer, condenser and
compressor.
11. Use the reverse order to reassemble the economizer
on the chiller. Be sure to install new gaskets at the
appropriate joints.
12. Torque all bolts to specifications. Consult with your
Trane service group for specific torques for your
economizer design.

WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by
Trane or others, refer to the appropriate
manufacturer's literature for allowable waiting periods
for discharge of capacitors. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged.
Use the following steps to remove the Tracer AdaptiView™
display arm if additional clearance is required.
1. Cut tie wraps holding wires inside of control arm and
remove wires from arm.
2. Remove 3-3/8-in. bolts from the angle bracket attached
to the control panel mounting bracket.
3. Use the reverse order to re-attach the arm to the
control panel mounting bracket.
