Routine Cleaning of E-Coated Coil Surfaces

Monthly cleaning with Environmentally Sound Coil Cleaner is essential to extend the life of coils. It is recommended that all coils including standard aluminum, pre-coated, copper/copper, or E-coated coils be cleaned with the Environ- mentally Sound Coil Cleaner as described below. Coil clean- ing should be part of the regularly scheduled maintenance procedures of the unit to ensure long life of the coil. Failure to clean the coils may result in reduced durability in the environment.

Environmentally Sound Coil Cleaner is non-bacterial, biodegradable and will not harm the coil or surrounding components such as electrical wiring, painted metal surfaces or insulation. Use of non-recommended coil cleaners is strongly discouraged since coil and unit durability could be affected.

The following field supplied equipment is required for coil cleaning:

•21/2 gallon garden sprayer

•water rinse with low velocity spray nozzle

Environmentally Sound Coil Cleaner Application Instructions

Perform the following procedure to clean the coil.

NOTE: Wear proper eye protection such as safety glasses during mixing and application.

1.Remove all surface debris and dirt from the coil with a vacuum cleaner.

2.Thoroughly wet finned surfaces with clean water and a low velocity garden hose, being careful not to bend fins.

3.Mix Environmentally Sound Coil Cleaner in a 21/2 gallon garden sprayer according to the instruc- tions included with the cleaner. The optimum solution temperature is 100 F.

CAUTION: DO NOT USE water in excess of 130 F. Enzymes in coil cleaner will be destroyed and coil cleaner will not be effective.

4.Thoroughly apply Environmentally Sound Coil Cleaner solution to all coil surfaces including finned area, tube sheets, and coil headers. Hold garden sprayer nozzle close to finned areas and apply cleaner with a vertical, up-and-down motion. Avoid spraying in horizontal pattern to minimize potential for fin damage. Ensure cleaner thoroughly penetrates deep into finned areas. Interior and exterior finned areas must be thoroughly cleaned.

5.Allow finned surfaces to remain wet with cleaning solution for 10 minutes. Ensure surfaces are not allowed 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.

CAUTION: Do not use bleach, harsh chemicals, or acid cleaners on outdoor or indoor coils of any kind. These types of cleaners are difficult to rinse, and they promote rapid corrosion of the fin collar — copper tube connection. Only use the Environmentally Sound Coil Cleaner.

Never use high pressure air or liquids to clean coils. High pressures damage coils and increase the airside pressure drop. To promote unit integrity, follow clean- ing and maintenance procedures in this document.
