Voltage Range: Power supplied to the chiller must fall within the voltage minimum to
maximum range listed in the table above. The chiller will not operate normally if the power
supply voltage falls below or above the tolerance range.
Maximum allowable voltage variance permitted between phases is 2%.
MCA: Minimum Circuit Ampacity (A) (Criteria used to select the wiring standard).
MFA: Maximum Fuse Amps (A) (Criteria used to select circuit breaker and ground error
circuit breaker [electricity leakage circuit breaker]).
MSC: Maximum Start Current (A)
RLA: Rated Load Amps (A) (Current required when operating under the following
conditions—Cooling: Outdoor Air Temperature: 8°1F DB / 66°F WB; Water Inlet / Outlet
Temperature: 54°F / 44°F).
FLA: Full Load Amps (A).
