Installation, Operation and Maintenance Manual - Data Aire

7.6 Wiring Diagrams
Every Data Aire evaporator, condenser, condensing unit or fl uid cooler comes with a wiring diagram.
These diagrams are ladder type schematics intended for service personnel. The intent is
to allow the technician to understand the wiring details associated with the electrical components
and how they interface with the controls as well as peripheral equipment (including secondary
heat exchangers).
The wiring diagram in the evaporator will indicate fi eld interface terminals to the secondary heat
exchanger. The internal wiring of the heat exchanger is found on a separate diagram which can
be found on the inside cover of the heat exchanger electrical box. Both diagram types are also
placed inside the shipping/warranty packet secured in the evaporator section.
Evaporator wiring diagrams will have a drawing number that starts with a three letter designation,
“DAP”. An example of a typical diagram is DAP-S-778. Wiring diagrams for condensers or
condensing units start with the three letter designation, “DRC”. A typical diagram example would
be DRC-S-001. Fluid coolers begin with the three letter designation “DFC”. A typical fl uid cooler
diagram would be DFC-S-001.
