2.7.5 Glycol Cooled Systems (G Models)
Systems equipped with a glycol-cooled system/pump
package require field wiring between the glycol unit

wire two control conductors from the terminal board
within the glycol unit, to the pump package electrical
box. Refer to the electrical schematic supplied with
your unit for the number of field wires needed and
