Has water been placed in drain pan to confirm proper drainage?
Are correct filters in place?
Refrigerant Piping
If leaks are found, report any leaks to ICE Warranty Service Dept.
C. Check Rated Voltage at Terminal Block for Imbalance before starting of Unit.
❒208/230V 1 Phase
❒380V 3 Phase 50Hz.
Measured Line to Line Volts L1&L2_______V.
(L1&L2 + L1&L3 + L2&L3)/3 = Avg. Voltage = _______________
Max. Deviation from avg. voltage = ______________volts
Voltage imbalance = (100 x Max. Deviation)/avg. Voltage = ___________%
A voltage deviation greater than 2% with the unit running should be addressed and corrected. Excess
voltage deviation can cause the compressor to overheat and to operate inefficiently.
Example: Maximum Deviation from Average Voltage X 100 (for Percent)
Measured Voltages:
Three phase units only check fan & compressor rotation.
❒208/230V 3 Phase
❒575 3 Phase 60 Hz.
L1 & L2 = 241 Volts
L1 & L3 = 243 Volts = 717 / 3 = 239 Average Voltage
L2 & L3 = 233 Volts
239 - 233 = 6
100 x 6/239 =2.5% Voltage Unbalance
L1&L3 ________V.
