3. Remove all surface loaded fibers and dirt 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 surface loaded coil will drive the fibers and dirt into
the coil, making cleaning efforts more difficult. Surface load-
ed fibers must be completely removed prior to using low ve-
locity 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 balanced coil cleaner in a
2-1/2 gallon garden sprayer according to the instruc-
tions 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 balanced
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 mini-
mize 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 rins-
ing. 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.
