1. Remove and discard high-fault bracing.
WARNING
Connection Leaks!
Failure to follow instructions below could result in
damage to the coil header and cause connection leaks.
Use a backup wrench when attaching piping to coils
with copper headers. Do not use brass connectors
because they distort easily.
2. Remove and discard power wire from breaker/terminal,
contactors, and motor terminals. See
use of backup wrench.
Note: Be sure to save motor terminal nuts for installation.
3. Remove and discard 1F1/2/3 line side harness.
4. Remove relay 1K11.
5. Remove and discard current transformers: 1T2-1, 1T2-2,
and 1T-31.
6. Remove and discard (if applicable) under/over voltage
transformers: T3-1, 1T3-2, and 1T3-1.
7. Remove and discard terminals 1x3.
8. Remove and save Fuse 1F1/2/3 for later use.
Note: This fuse will be rated at 5 amps (380 to 415 volts)
and 4 amps (460 volts).
9. Remove starter module 1A3.

Note: The liquid level red power wire (64A) is connected
to J3 Pin 1 of the starter module. This will be
connected to the power supply 1A2. Refer to
"Panel Control Wiring," p.

Figure 36 during the following procedure.
Location 4, as shown in Figure
used to route the power wire which connects the unit to the
AFD.
Test-fit the 2.5-inch conduit fittings at the locations to
ensure the conduit and or fitting will not interfere with the
unit evaporator and or panel before drilling holes.
Depending on the unit's evaporator size the holes may be
located further inward than specified without interference
between conduit and evaporator. Locating the holes
further inward will aid in harness installation later. Before
drilling, make sure conduit and fittings will not interfere with
evaporator or panel door.
