Disassembly
11. Torque all bolts to specifications. Consult with your
Trane service group for specific torques for your
economizer design.
Condenser/Evaporator
Disassembly
After the compressor assembly has been removed, the
condenser and evaporator shells can be taken apart at
flanged connections to reduce the horizontal clearance
required for the chiller installation.
WARNING
Heavy Objects!
Failure to follow instructions below or properly lift
component could result in component dropping and
possibly crushing operator/technician which could
result in death or serious injury, and equipment or
property-only damage. Ensure that all the lifting
equipment used is properly rated for the weight of the
component being lifted. Each of the cables (chains or
slings), hooks, and shackles used to lift the component
must be capable of supporting the entire weight of the
component. Lifting cables (chains or slings) may not be
of the same length. Adjust as necessary for even
component lift.
1. Ensure that condenser and evaporator shells are
securely supported on level ground. If not, shim under
the bases.
2. Support the condenser with rigging using the lifting
holes on the tube sheets. See Figure 15. Do not lift the
shell, simply support it to avoid slipping as the bolts
are removed from the connecting flange.

3. Remove the bolts from the flanges connecting the
evaporator tube sheet and condenser shell support
(see
Figure
16). Then remove the bolts from the
flanges connecting the shells.
4. Reassemble the evaporator and condenser shells in
the reverse order.
Note: Install the top bolts first as these have limited
clearance and act as dowel pins.
