Electrical
• Comply with proper local electrical codes.
• Contact a licensed electrician to perform the electrical installation.
• The electrician should verify that the wiring is adequate in the installation area.
• Refer to the nameplate label on the rear of the unit for detailed electrical requirements.
Power cord: Some units include a power cord. Hardwire the power cord to an electrical service
disconnect or add a plug with the appropriate rating and type.
For units without a power cord, connect incoming power to the labeled terminal block inside the
unit’s electrical enclosure.
Service disconnect: Use a dedicated service disconnect and time-delay fusing or circuit breaker per
the electrical requirements on the unit’s nameplate label.
Phase monitor: Chillers configured for 3-phase electrical include a phase monitor. Refer to the fault
indicators provided on the phase monitor and contact a licensed electrician to correct any faults.
Energizing the service: Electrical power must be applied to the chiller at least 12 hours in advance of
startup. This energizes the crankcase heater and drives out any accumulated liquid refrigerant in the
compressor.
