3. Remove all surface loaded fibers and dirt with a vacuum
cleaner. If a vacuum cleaner is not available, a soft non-metal-
lic 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.
4. Using a low velocity garden hose thoroughly wet finned sur-
faces with clean water. Be careful not to bend the fins.
5. Mix Totaline environmentally sound coil cleaner in a 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
RIGID cleaner with a vertical, up-and-down motion. Avoid spraying
SUPPORT
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. Reap-
ply 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. Pro-
tect fins from damage from the spray nozzle.
13. Replace top cover and rear corner posts.
