Just as a note, when using that particular exchanger as a condenser, it should actually be mounted upside down compared to how the picture shows it, with the connection that would then face down as the liquid line connection. Water flow should be opposite to refrigerant flow whether used as a condenser or evaporator, only exception is in a heat pump where the refrigerant flow reverses, at which point you have the water flow going opposite in the mode that is used more.
