Totaline Environmentally Sound Coil Cleaner Application Instructions:
Note: Proper eye protection such as safety glasses is recommended during mixing and application.
1. Turn off unit power.
2. 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. 47.
3. 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 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.
4. Using a low velocity garden hose thoroughly wet finned surfaces with clean water. Be careful not to bend the fins.
5. Mix Totaline environmentally sound coil cleaner in a 21/2 gallon garden 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°C), as the enzymatic activity will be destroyed.
6. Thoroughly apply Totaline® environmentally sound coil cleaner solution to all coil surfaces including the finned
area, tube sheets and coil headers.
7. 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.
8. Ensure cleaner thoroughly penetrates deep into finned areas.
9. 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 nozzle.
Protect fins from damage from the spray nozzle.
13. Replace top cover and rear corner posts.
