6000/8000Scm System Wiring – Option A: Dual Power / Valve Control
Under this configuration the Primary Evaporator and Condensing units are separately
powered, the Secondary Evaporator is powered from the Primary Evaporator, and the
Condensing unit turns on and off based on suction pressure, as follows:
•
Both the Primary and Secondary Evaporators include a factory installed liquid line
solenoid valve (LLSV), which is controlled by the Evaporator temperature controller
in the Primary Evaporator. The Condensing unit is controlled by a low pressure
switch which reacts to the suction pressure and senses whether the LLSV is open
or closed.
•
When the controller temperature set-point is reached, both of the LLSV close,
causing the system to pump down until the low pressure switch shuts off the
Condensing unit.
•
When the controller calls for cooling, both of the LLSV open, causing the suction
pressure to rise and activate the Condensing unit.
Field power wiring is connected to the Primary Evaporator and Condensing units, and
interconnect wiring between the Primary and Secondary Evaporators. No
interconnecting wiring is needed between the Evaporator and Condensing unit.
Primary Evaporator Field Power Wiring:

Connect line lead to Primary Evaporator terminal "L"

Connect neutral lead to Primary Evaporator terminal "N"

Connect power ground to grounding lug on Primary Evaporator
Secondary Evaporator Field Interconnect Wiring from Primary Evaporator:

Interconnect power leads to terminals “18”, “20”, “22”, and “26”

Interconnect 18/2 thermostat wiring to terminals “8” and “9”

Connect power ground to grounding lug on Secondary Evaporator
Condensing Unit Field Power Wiring:

Connect line lead to Condensing unit terminal "L1"

Connect neutral lead to Condensing unit terminal "L2"

Connect power ground to grounding lug on Condensing unit.
