Set the pump module in place and mount the cooling control panel. Use shims
or flat washers to make sure the pump module is level and solid (not rocking). The
cooling control panel should be mounted to a solid surface, or structure, able to
withstand the minor vibration of the contactors without coming loose.
Connect one conduit from the control panel to the pump module and one to the
heat exchanger for AC wiring. Depending on local wiring codes and personal
preference, another set of conduit runs may be installed for the control and status
wires to the pump module and the heat exchanger. The small signal wires and the
AC wiring should never be run in the same conduit.
Open the Isolator switches on the cooling control panel, pump module and heat
exchanger. This will allow them to be closed one at a time later to check for wiring
problems.
Connect the AC wiring between the cooling control panel and the pump
module and heat exchanger. Follow the AC Power Flow Diagrams and Electrical
Installation Diagrams mentioned at the beginning of this section. All AC
connections are connected to terminals labeled X1.
Connect the control and status wires between the cooling control panel and the
pump module with the supplied 16-2-12C (screened) multi-conductor cable.
These connections are on Electrical Installation Drawing, 843-5550-189 or 843-
5550-218. These low level signals connect from terminals X1-8 thru X1-15 in the
pump module to X2-21 thru X2-28 in the cooling control panel. Table 2-1 is a
connection reference chart.
