GENERAL

These installation instructions cover the 30HK, HL, HWA, HWB, HWC, and HWS units. The HL and HWA are con- denserless units, and the HK, HWB, HWC, and HWS units are all ¯uid cooled. In addition, the 30HK and HWC units have a standard mechanically cleanable condenser and the 30HWS unit has a mechanically cleanable condenser spe- ci®cally designed for sea coast applications.
