Mechanical lifting equipment is also required to remove
the sub assemblies from the main chassis. Subassem-
blies weigh a minimum of 205 pounds and as much as
1500 pounds each.
Wiring
All low voltage wires are connected using quick-connect
plugs. NEMA does not allow quick-connect plugs for
power (high voltage) wiring. For this reason, all power
wires have raw ends and are ‘hardwired’ to terminal
blocks in the unit and require handtools for removal.
These power wires must be labeled prior to removal to
avoid problems.
Piping
All water piping is iron with grooved (Victualic ® ) connec-
tions.
Refrigeration circuits are copper pipe and do not require
any disassembly and reassembly.
Main Electrical Panel Removal
The main electrical panel is removed as follows.
1. Unplug the wiring harness that connects the EPiC™
keypad, reset buttons and selector switches from the
panel door to the main electrical panel.
2. Remove the panel door by lifting it from its hinges.
Carefully set it away from the unit to help prevent
damage during the remaining disassembly process.
3. Unplug all control wiring harnesses that run from the
main electrical panel to the main cabinet section. All
wiring connecting the main electrical panel to the unit
passes through knockouts on the left inside corner.
These plugs are labeled for correct re-installation.
4. Disconnect all high voltage wiring to the fan motors.
5. Verify that all electrical connections to the unit from
the control panel have been disconnected.
6. Support the electrical panel from above or below to
prevent it from falling once the connecting bolts have
been removed.
7. Loosen and remove the section bolts that fasten the
main electrical panel to the main cabinet sections, as
shown in Figure 3.
8. Set the main electrical panel aside, away from the
unit to help prevent damage during the remaining dis-
assembly process.

Filter Rack and Coil Cabinet Removal
The coil cabinet and filter rack can be removed from the
main chassis, as follows. See Figure 4 for fastener loca-
tions.
1. Remove the filter rack from the coil cabinet by screw-
ing out the fasteners from the four corners of the rack.
IMPORTANT! Filter rack mounting bolts are
a specific length so as to not contact the coil
behind the bulkhead. If any are lost, replace-
ment bolts must be the same length.
