Notes

*1. The cylinder environment must frost-free.

·  Nominal operating condition:
   (A7/W35) – Outside air temperature (DB/WB): 7/6°C, Water temperature (inlet/outlet) 30/35°C.
   (A35/W7) – Outside air temperature (DB/WB): 35/24°C, Water temperature (inlet/outlet) 12/7°C.

·  Power Input: At distance of 1m from outdoor unit.

·  Power input figures do NOT include pump input figures as pump input depends on local system configuration.

·  Split type specifications are just examples of the case that the units are connected to a plate heat exchanger produced by Alfa Laval. Actual specifications depend on local system configuration. The specifications above are based on Alfa Laval ACH70-50H Heat Exchanger being used.
