15. Aluminum Indoor Coil Cleaning
(Qualified Servicer Only)
This unit is equipped with an aluminum tube evaporator coil.
The safest way to clean the evaporator coil is to simply flush
the coil with water. This cleaning practice remains as the
recommended cleaning method for both copper tube and
aluminum tube residential evaporator coils.
It has been determined that many coil cleaners and drain
pan tablets contain corrosive chemicals that can be harmful
to aluminum tube and fin evaporator coils. Even a one-time
application of these corrosive chemicals can cause premature
aluminum evaporator coil failure. Any cleaners that contain
corrosive chemicals including, but not limited to, chlorine and
hydroxides, should not be used.
An alternate cleaning method is to use one of the products
listed in TP-109* to clean the coils. The cleaners listed are
the only agents deemed safe and approved for use to clean
round tube aluminum coils. TP-109 is also available on the
web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of any chemical
cleaners.
