14. 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 resi-

dential evaporator coils.

It has been determined that many coil cleaners and drain pan

tablets contain corrosive chemicals that can be harmful to alumi-

num tube and fin evaporator coils. Even a one-time application of

these corrosive chemicals can cause premature aluminum evapo-

rator 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 Part-

ner Link > Service Toolkit.

NOTE: Ensure coils are rinsed well after use of any chemical cleaners.
