ELECTRICAL WIRING SCHEMATICS
7.1 INTRODUCTION
This section contains the Electrical Schematics and Wiring Diagrams. The diagrams are presented as follows:
Figure 7--1 provides the legend for use with Figure 7--2, the schematic diagram for units with single--phase motor,
normal evaporator fan capability, and Figure 7--3, the schematic diagram for units with single--phase
motor, single evaporator fan capability.
Figure 7--2 provides the basic schematic diagram for units with single--phase motor, normal evaporator fan
capability.
Figure 7--3 provides the basic schematic diagram for units with single--phase motor, single evaporator fan capability.
Figure 7--4 provides the legend for use with Figure 7--5, the schematic diagram for units with three--phase
evaporator motor capability.
Figure 7--5 provides the schematic diagram for units with three--phase evaporator motor capability.
Figure 7--6 supplements Figure 7--2 and Figure 7--3 and provides schematics for TransFRESH and Emergency
Bypass.
Figure 7--7 supplements Figure 7--2 and Figure 7--3 and provides the schematic and wiring diagrams for the
Electronic Partlow Recorder.
Figure 7--8 supplements Figure 7--2, Figure 7--3 and Figure 7--5 and provides the schematic and wiring diagrams for
Upper and Lower Vent Position Sensors.
