6.8 HEAT EXCHANGER CLEANING

For hard water installations, AERCO high recommends use of its Scale Reducer system. The
Scale Reducer, model SR300, is strongly recommended for installations in areas with hard water
(>3.5 grains/gal, >59.9 mg/L). It provides an economical, maintenance free treatment of hard
water without the use of salt or any chemicals. The SR300 prevents new scale build-up and
eliminates existing build-up in hot water boilers, boilers and storage tanks, hot water piping,
valves, recirculation lines and pumps, mixing valves, showerheads and other plumbing fixtures.
This eliminates the associated heat exchanger overheating and lets the hot water boiler continue
to perform at its peak efficiency (low-water heating cost). In addition to reduced inspection
frequency, the periodic maintenance to remove and flush the hot water boiler for scale deposits is
no longer necessary.
For hard water applications, AERCO recommends
annually to maintain maximum heat transfer efficiencies using a solution of HydroSkrub and
water. HydroSkrub is distributed by AERCO International, Inc. and is designed to dissolve the
toughest water scale, lime, mud and rust deposits from virtually any type of water-based
equipment.
Please review MSDS, specifications, and our website
additional information, or call technical service at (800) 526-0288.
Do not drain the unit without venting the shell! A vacuum in the unit may displace
the head liner causing serious damage not covered by warranty.
