moving side to side and from top to bottom.
Allow the cleaning solution to soak for 5 to
10 minutes. Then move on to the exterior
using the same method.
Rinse - Using pressurized potable water such
as a garden hose, (< 100 psi), rinse the coils
and
continue to always work in
sections/panels.
Continue until all coil areas on the inside of
the unit have been rinsed. Note: Coils must
always be cleaned / back flushed, opposite
of airflow to prevent impacting the dirt into
the coil.
Repeat these steps with GulfClean ™ Salt
Reducer. When finished replace all panels
and tops that were removed.
Microchannel Coil Cleaning
Cleaning microchannel coils is necessary in
all locations. In some locations it may be
necessary to clean the coils more or less often
than recommended. Condenser coil must be
cleaned at a minimum of once a year. In
locations where there is commonly debris or
a condition that causes dirt/grease build up it
may be necessary to clean the coils more
often. Proper procedure must be followed at
every cleaning interval. Using improper
cleaning technique or incorrect chemicals
will
result in coil damage, system
performance fall off, and potentially leaks
requiring coil replacement.
Documented
routine cleaning of
microchannel coils with factory provided e-
coating is required to maintain coating
warranty coverage. Use the E-Coated Coil
Cleaning section for details on cleaning e-
coated coils.
Field
applied coil coatings are not
recommended with microchannel coils.
Allowed Chemical Cleaners and Procedures
AAON recommends certain chemicals that
can be used to remove buildup of grime and
debris on the surface of microchannel coils.
These chemicals have been tested for
performance and safety and are the only
chemicals that AAON will warrant as correct
for cleaning microchannel coils.
There are two procedures that are outlined
below that will clean the coils effectively
without damage to the coils. Use of any other
procedure or chemical may void the warranty
to the unit where the coil is installed.
With
all procedures make sure the unit is off
before starting.
The water pressure used to clean must not
exceed 100 psi, from no closer than 6 inches
from the coils, and with the water aimed
perpendicular to the coils.
#1 Simple Green
Simple Green is available from AAON Parts
and
Supply (Part# T10701) and is
biodegradable with a neutral 6.5 pH A 4 to 1
solution is recommended. Use the following
procedure.
1. Rinse the coil completely with water.
Use a hard spray but be careful not to
bend or damage the fins. A spray that is
too hard will bend the fins. Spray from
the fan side of the coil.
2. With a pump sprayer filled with a mix
of 4 parts water to one part Simple
Green spray the air inlet face of the coil.
Be sure to cover all areas of the face of
the coil.
Electric shock hazard. Shut off all
