CAUTION
Failure to adhere to the following product cleaning
guidelines can result in heat exchanger damage,
including leaks or loss of performance.
Follow these recommended cleaning procedures
when cleaning is required:
•
Use clean, potable water to clean the coils.
City tap water is recommended. Do not use
chemical cleaners to clean the coils.
•
Remove surface debris such as dirt, leaves,
insects, fibers, or other debris with a vacuum
cleaner that has a soft attachment rather
than a metal tube. Do not contact the heat
exchanger with the vacuum nozzle, air nozzle,
or any other tool. Compressed air blown from
the inside out can also be used.
•
When brushing dirt and debris off the face
of the heat exchanger, a clean, unused, soft
bristle (not wire) brush can be used. Take
care to prevent damage to the coil. The
brush should not be contaminated with other
metallic debris such as copper shavings.
•
Water pressure for cleaning should not
exceed the pressure of the spray from a
common garden hose with attached nozzle.
Use a gentle spray from a spray nozzle with
a plastic end or put your finger on the end of
the spray nozzle to reduce impact and provide
a gentle spray. Do not use a pressure washer,
as it causes damage to the heat exchanger.
Cleaning should be from the inside out to drive
fibers and dirt out of the heat exchanger.
Hot water and steam coils
Inspect the hot water and steam coils for dirt and
debris, and clean when necessary using the same
procedure as the condenser and evaporator coils.
