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:

• 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
2
1
/
2
gallon garden sprayer according to the instruc-
tions included with the cleaner. The optimum
solution temperature is 100 F.
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.
X. REPLACEMENT PARTS
A complete list of replacement parts is available from your
Bryant dealer.
CAUTION: DO NOT USE water in excess of 130 F.
Enzymes in coil cleaner will be destroyed and coil
cleaner will not be effective.
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.
