Round Tube Plate Fin Condenser Coil Cleaning

Routine cleaning of coil surfaces is essential to maintain proper
operation of the unit. Elimination of contamination and removal of
harmful residues will greatly increase the life of the coil and ex-
tend the life of the unit. The following maintenance and cleaning
procedures are recommended as part of the routine maintenance
activities to extend the life of the coil.

Remove Surface Loaded Fibers

Surface loaded fibers or dirt should be removed with a vacuum
cleaner. If a vacuum cleaner is not available, a soft non-metallic
bristle brush may be used. In either case, the tool should be ap-
plied in the direction of the fins. Coil surfaces can be easily dam-
aged (fin edges can be easily bent over and damage to the coating
of a protected coil) if the tool is applied across the fins.
NOTE: Use of a water stream, such as a garden hose, against a
surface loaded coil will drive the fibers and dirt into the coil. This
will make cleaning efforts more difficult. Surface loaded fibers
must be completely removed prior to using low velocity clean wa-
ter rinse.

Periodic Clean Water Rinse

A periodic clean water rinse is very beneficial for coils that are ap-
plied in coastal or industrial environments. However, it is very im-
portant that the water rinse is made with very low velocity water
stream to avoid damaging the fin edges. Monthly cleaning is rec-
ommended.

Routine Cleaning of Coil Surfaces

Routine cleaning with Totaline
is essential to extend the life of coils. This cleaner is available
from Carrier Replacement Components as part number P902-
0301 for a one-gallon container, and part number P902-0305 for a
5-gallon container. It is recommended that all coils, including the
standard copper tube aluminum fin or e-coated coils be cleaned
with the Indoor and Outdoor Coil Cleaner as described below.
Coil cleaning should be part of the unit's regularly scheduled
maintenance procedures to ensure long life of the coil. Failure to
clean the coils may result in reduced durability in the environment.
Avoid the use of:
• coil brighteners
• acid cleaning prior to painting
• high pressure washers
• poor quality water for cleaning
Totaline Indoor and Outdoor Coil Cleaner is non-flammable, hy-
poallergenic, nonbacterial, and a USDA accepted biodegradable
agent that 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.

Totaline Indoor/Outdoor
Instructions

REQUIRED EQUIPMENT

• 2-1/2 gallon garden sprayer
• Water rinse with low velocity spray nozzle
Harsh chemicals, household bleach or acid or basic cleaners
should not be used to clean coils of any kind. These cleaners
can be very difficult to rinse out of the coil and can accelerate
corrosion at the fin/tube interface where dissimilar materials
are in contact. If there is dirt below the surface of the coil, use
the Totaline Indoor and Outdoor Coil Cleaner as described
below.
High velocity water from a pressure washer, garden hose, or
compressed air should never be used to clean a coil. The force
of the water or air jet will bend the fin edges and increase
airside pressure drop. Reduced unit performance or nuisance
unit shutdown may occur.

Application Instructions

1. Proper eye protection such as safety glasses is recommended
during mixing and application.
2. Remove all surface loaded fibers and dirt with a vacuum
cleaner as described above.
3. Thoroughly wet finned surfaces with clean water and a low
velocity garden hose, being careful not to bend fins.
4. Mix Indoor and Outdoor Coil Cleaner in a 2-
sprayer according to the instructions included with the
cleaner. The optimum solution temperature is 100°F (38°C).
NOTE: Do NOT USE water in excess of 130°F (54.4°C), as
the enzymatic activity will be destroyed.
5. Thoroughly apply Totaline Indoor and Outdoor Coil Cleaner
solution to all coil surfaces including finned area, tube sheets
and coil headers.
6. 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.
7. Ensure cleaner thoroughly penetrates deep into finned areas.
8. Interior and exterior finned areas must be thoroughly cleaned.
