TOTALINE ENVIRONMENTALLY BALANCED COIL

CLEANER APPLICATION EQUIPMENT

•

2-1/2 gallon garden sprayer

•

water rinse with low velocity spray nozzle

CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in accelerated

corrosion of unit parts.

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 environmentally

balanced coil cleaner.

IMPORTANT: 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,

resulting in reduced unit performance.

Totaline Environmentally Sound Coil Cleaner Application

Instructions:

NOTE: Proper eye protection such as safety glasses is recom-

mended during mixing and application.

Turn off unit power.

Remove screws holding rear corner post and top cover in

place. Pivot top cover up 12 to 18 inches (305 to 457 mm)

and support with a rigid support. See Fig. 39.

Remove all surface loaded fibers and dirt 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 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 sur-

face loaded coil will drive the fibers and dirt into the coil, making

cleaning efforts more difficult. Surface loaded fibers must be com-

pletely removed prior to using low velocity clean water rinse.

Using a low velocity garden hose thoroughly wet finned

surfaces with clean water. Be careful not to bend the fins.

Mix Totaline environmentally balanced coil cleaner in a

2-1/2 gallon garden sprayer according to the instructions

included with the cleaner. The optimum solution tempera-

ture is 100°F (38°C).

NOTE: Do NOT USE water in excess of 130°F (54°C), as the

enzymatic activity will be destroyed.

Thoroughly apply Totaline environmentally balanced coil

cleaner solution to all coil surfaces including the 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 spray-

ing 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.

10. Finned surfaces should remain wet with cleaning solution

for 10 minutes.

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

Reapply cleaner as needed to ensure 10-minute saturation

is achieved.

12. Thoroughly rinse all surfaces with low velocity clean

water using downward rinsing motion of water spray noz-

zle. Protect fins from damage from the spray nozzle.

13. Replace top cover and rear corner posts.
