same time, so the starting current of 970-1490 models are the single compressor start-up current value.
Note:
(1) Values obtained at standard unit operating conditions: evaporator entering/leaving water
temperature = 12°C/7°C. Condenser entering/leaving water temperature = 30°C/35°C.
(2) For the dual compressor unit, we suggest equipped with breaker for each circuit.
