solution to all coil surfaces including finned _uea, tube

sheets, and coil headers. Hold gmden sprayer nozzle

close to finned areas and apply cleaner with a vertic_d,

up-and-down motion. Avoid spraying in horizontal

pattern to minimize potential for fin dmnage. Ensure

cleaner thoroughly penetrates deep into finned _ueas.

Interior and exterior finned areas must be thoroughly

cleaned.

5. Allow finned surfaces to remain wet with cleaning solu-

tion for 10 minutes. Ensure surfaces are not _dlowed to

dry before rinsing. Reapply cleaner as needed to ensure

10-minute saturation is achieved.

6. Thoroughly rinse all surfaces with low velocity clean

water using downward rinsing motion of water spray

nozzle. Protect fins from damage from the spray nozzle.

Do not use bleach, harsh chemicals, or acid cleaneLs on out-

door or indoor coils of any kind. These types of cleaneLs me

difficult to rinse, and they promote rapid corrosion of the tin

collar -- copper tube connection. Only use the Environ-

mentally Sound Coil Cleanel:

Never use high pressure air or liquids to clean coils. High

pressures damage coils and increase the airside pressure

&op. To promote unit integrity, follow cleaning and main-

tenance procedures in this document.
