RPS/RDT Factory Split at Condensing Unit
Phase III. Reconnecting power and control wiring
The wire harnesses are coiled in the condenser section base rail
(see Figure 49). The power wires into the lower base rail
raceway and the control wires into the upper raceway.
1
Uncoil the harnesses and feed them through the base rail of
the air handler section and make the proper connections.
The power wires terminate to the load side of the
contactors; the control wires plug into the plug patch panel.
2
The liquid line solenoid valve harness is split into two
harnesses. Install one half in the plug patch panel in the
main control box (see Figure 49).
3
The other half of the harness is located in conduit on the
bulkhead of the air handler section (see Figure 49).
4
Terminate the conduit to the vertical raceway in the
condenser section (see Figure 50).
5
Wire nut the ends of the two harnesses together.
6
The optional hot gas bypass solenoid valve harness is
coiled in the upper raceway of the condenser base rail (see
Figure 50). Route the plug end of the harness through the
air handler raceway and into the main control cabinet and
plug into the plug patch panel.
