1. Mark and disconnect the power wiring at the
compressor motor terminal lugs inside the starter
panel.
2. Mark and disconnect control wiring entering the
starter panel.
3. Remove the bolts securing the bottom of the starter
to the brackets on the evaporator.
4. To move the starter panel away from the chiller, it is
recommended that a fork truck be used. Position
the truck so that it is ready to take up the weight of
the starter panel. The panel is top-heavy and must
be adequately secured before moving. Refer to
Table 12, p. 19 for starter weights.

5. Loosen the bolts which hold the starter to the flange
on the motor. Steady the starter panel as the
retaining bolts are removed because the panel will
tip forward. See Figure 19, p.
6. Support the weight of the starter panel with the fork
truck and carefully remove the starter panel from
the chiller. Store the panel in a clean dry area free of
any corrosive agents. When ready, reassemble the
panel on the chiller in reverse order.

Condenser/Evaporator
Disassembly
After the compressor assembly has been removed on
separable shell units, the condenser and evaporator
shells can be taken apart at flanged connections to
reduce the horizontal clearance required for the chiller
installation.

N N o o t t e e : : Brace condenser legs to prevent flexing. Do not
move the condenser horizontally without bracing
legs.
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
not lift the shell, simply support it to avoid slipping
as the bolts are removed from the connecting
flange.
