* Recommended only when unit will be run in an extreme condensing mode for prolonged periods of time.
** In areas where water quality is poor or not qualified, inspection and cleaning may be required to assure
trouble-free operation. Hard water deposits must be removed to prevent corrosion and leaking. Checking
at more frequent intervals may be required to prevent scale buildup. See page 6-13 for information about
removing scale deposits using AERCO HydroSkrub scale remover.
