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 that is placed inside the evaporator.
Evaporator wiring diagrams will have a drawing number which starts out with the three letter
designation, “DAM”. An example of a typical diagram is DAM-S-378 S. Wiring diagrams for
condensers or condensing units start out with the three letter designation, “DRC”. An example of
a typical diagram is DRC-S-001. Wiring diagrams for fl uid coolers start out with the three letter
designation, “DFC”. An example of a typical diagram is DFC-S-001.
