Note:
• Nominal cooling capacity is based on the following conditions: 12/7°C EWT and LWT, 35°C
ambient temperature;
• Maximum running current refers to the maximum current when the unit is working in the
allowable area.
• Shipping quality include steel packing quality. Operating quality include the quality of water in
the water-side heat exchanger, without steel packing quality.
