Thanks to Luis Chacon at Trane Parts in Long Beach for providing this information!
As
the cooling season moves into high gear, it is important to remember that
Microchannel condenser coils are more susceptible to corrosion due to their
aluminum construction, and cleaning with cleansers or detergents is strongly
discouraged.
Why
this is important to the parts organization: It is important that all service
technicians and servicing contractors are aware of the proper cleaning
techniques for Microchannel coils. Cleaning the coil with water ONLY with
a spray nozzle pressure below 600 psi is recommended. Only in extreme
cases should a chemical cleaner be used; one cleaner recommended is CHM00351,If
a cleaner is used, it must be thoroughly rinsed with water even if the product
is considered a “No Rinse” cleaner. See Trane's full document by clicking the link below.
