An area of the heat exchanger may be divided into a plurality of regions, such that a first nozzle is coupled to the first outlet port and provided above a first region of the plurality of regions and a second nozzle is coupled to the second outlet port and provided above a second region of the plurality of regions. The control valve may selectively direct the flow of water toward the first nozzle or the second nozzle to clean a desired region.</p> |
