Use the following steps to remove the control panel if
additional horizontal clearance is required.
1. Mark and disconnect incoming wiring to the control
panel.
2. Remove the bolts from the bottom of the panel
which secure the panel to the lower mounting
bracket.
3. Loosen the bolts on the back of the panel which
secure the panel to the top (suction elbow)
mounting bracket. See
Figure 18, p. 27 .
Figure 18. Control panel mounting bracket
4. Two people will be needed to lift the panel clear of
the chiller. Refer to Table 10, p. 18 for control panel
weight. Steady the panel as the top retaining bolts
are removed. Then lift the panel clear. Store the
panel in a clean dry area.
5. Use the reverse order to reassemble the control
panel.
Unit-mounted Starter Removal
Additional horizontal and vertical clearances may be
obtained by removing the unit-mounted starter on
chillers so equipped. See
Figure 19, p. 27 and Figure
20, p. 27 .
N No otte e:: Unless otherwise stated, lift only vertically on
starter-provided devices. Refer to all starter-
related manuals prior to lifting. If needed, use a
spreader bar to avoid angles in chains and
reduce required lifting height clearance.

The following procedure assumes the chiller is new
and has never been installed and therefore there is no
electrical power connected to the chiller. If there is
power to the unit, follow proper lockout/tagout
procedures, and any other applicable safety
regulations regarding electric power.
