provided notation is made on schematic to aid field
servicing of equipment. When sourcing extension cable,
consideration should be given towards Belden 83754 for
14 AWG or equivalent as suitable. The inner foil shield
and the outer braid shield should be grounded as close
as possible to the EXV module in the control cabinet.
The expansion valve wiring cannot run in conduit with
other wiring that is over 24 Volts AC.
6. A flow switch must be installed in the leaving chilled
water line per manufacturer's instructions and wired to

splice a 4 conductor, shielded cable, with drain wire. This
cable needs to be a minimum of 22 AWG. Preferably the
conductors are colored white, black, blue, and brown but
