Remove Surface Loaded Fibers

Surface loaded fibers or dirt should be removed with a vac-

uum cleaner. If a vacuum cleaner is not available, a soft non-

metallic bristle brush may be used. In either case, the tool

should be applied in the direction of the fins. Coil surfaces

can be easily damaged (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 water rinse.

Periodic Clean Water Rinse

A periodic clean water rinse is very beneficial for coils that

are applied in coastal or industrial environments. However,

it is very important that the water rinse is made with very

low velocity water stream to avoid damaging the fin edges.

Monthly cleaning as described below is recommended.

Routine Cleaning of Coil Surfaces

Monthly cleaning with Totaline® environmentally sound coil

cleaner is essential to extend the life of coils. This cleaner is

available from Replacement parts division 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 standard aluminum, pre-coated, copper/copper

or E-coated coils be cleaned with the Totaline environmentally

sound 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 environmentally sound coil cleaner is non-flammable,

hypoallergenic, nonbacterial, and a USDA accepted biode-

gradable 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® Environmentally Sound Coil Cleaner Application

Equipment

•2

gallon garden sprayer

• Water rinse with low velocity spray nozzle

Totaline Environmentally Sound Coil Cleaner Application

Instructions

1. Proper eye protection such as safety glasses is recom-

mended during mixing and application.

2. Remove all surface loaded fibers and dirt with a vac-

uum 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 Totaline environmentally sound coil cleaner in a

gallon garden sprayer according to the instruc-

tions included with the cleaner. The optimum solu-

tion temperature is 100 F.

NOTE: Do NOT

USE water in excess of 130 F, as the enzy-

matic activity will be destroyed.

5. Thoroughly apply Totaline environmentally sound

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.

9. Finned surfaces should remain wet with cleaning

solution for 10 minutes.

10. Ensure surfaces are not allowed to dry before rinsing.

Reapplying cleaner as needed to ensure 10-minute

saturation is achieved.

11. 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.

B. Condensate Drain

Check and clean each year at the start of the cooling season.

In winter, keep drains and traps dry. An access panel is

located above the condensate connection to allow easy clean

out of the condensate pan. The first time the panel is

removed, the insulation behind the access panel will need to

be cut away. Carefully cut the insulation with a knife or

blade on three sides so the insulation can be folded out of the

way during cleaning. Be careful not to damage components

behind the insulation while cutting. Once cleaning is com-

pleted, fold the insulation back into place and secure the

access panel in the original position.

C. Filters

Clean or replace at start of each heating and cooling season,

or more often if operating conditions require. Refer to Table 1

for type and size.

D. Outdoor-Air Inlet Screens

Clean screens with steam or hot water and a mild detergent.

Do not use throwaway filters in place of screens. See Table 1

for quantity and size.

E. Main Burner

At the beginning of each heating season, inspect for deterio-

ration or blockage due to corrosion or other causes. Observe

the main burner flames. Refer to Main Burners section on

page 41.

CAUTION: Harsh chemicals, household bleach or

acid or basic cleaners should not be used to clean

outdoor or indoor 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

environmentally sound coil cleaner as described

above.

CAUTION: 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.
