Installation

WARNING

Ground Wire!

All field-installed wiring must be completed by qualified personnel. All field-installed wiring must comply with NEC and applicable local codes. Failure to follow this instruction could result in death or serious injuries.

WARNING

Grounding Required!

Follow proper local and state electrical code on requirements for grounding. Failure to follow code could result in death or serious injury.

[ ] Install proper grounding wires to an earth ground.

Field Installed Control Wiring Requirements

115 Volt Control Wiring (All Units)

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

[ ] Verify that the Control transformer (1T1) is wired for the proper operating voltage.

[ ] Connect properly sized wiring to the liquid line solenoid valve(s).

[ ] Connect properly sized wiring to the hot gas bypass solenoid valve(s), if applicable, to operate with the unit. Refer to the unit wiring diagram that shipped with the unit.

[ ] Install the interlock circuitry wiring for the air handling unit or the chilled solution pump to permit compressor operation after the fan or chilled solution pump has started, i.e., proof of fan operation device, fan starter auxiliary contacts or pump starter station, pump starter auxiliary contacts, proof of flow device, etc). Refer to the field connection diagram that shipped with the unit for interlocking information.

[ ] Install properly sized power supply wiring, with over current protection, to the proper termination point for the field provided economizer actuator(s), if applicable. Refer to the “Economizer Actuator Circuit” illustrated in the “Field Installed Control Wiring” section.

”No Controls” Units

[ ] A field provided “step” controller must be installed and properly wired. Refer to the field connection diagram for connection information.

“EVP” Chiller Units

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

[ ] Install the EVP chiller remote panel.

[ ] Install and connect properly sized control wiring to the proper termination points between the remote panel and the unit control panel.
