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 sur-

faces 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

surface loaded coil will drive the fibers and dirt into the coil,

making cleaning efforts more difficult. Surface loaded fibers

must be completely 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 sound coil cleaner in a 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 sound 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

RIGID

apply cleaner with a vertical, up-and-down motion.

SUPPORT

Avoid spraying in horizontal pattern to minimize poten-

tial 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 solu-

tion for 10 minutes.

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

Reapply cleaner as needed to ensure 10-minute satura-

tion is achieved.

12. 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.

13. Replace top cover and rear corner posts.
