Cleaning Option E Coated Coils
WARNING
Prior to cleaning the unit, turn off and lock out the main
power switch to the unit and open all access panels.
The following cleaning procedures are recommended as part
of the routine maintenance activities for Option E Coated Coils.
Documented routine cleaning of Option E Coated Coils is
required to maintain warranty coverage.
Remove Surface Loaded Fibers
Surface loaded fibers or dirt should be removed prior to water
rinse to prevent further restriction of airflow. If unable to back
wash the side of the coil opposite that of the coils entering air
side, then surface loaded fibers or dirt should be removed 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 bent over) if the tool is applied
across the fins.
NOTE:
Use of a water stream, such as a garden hose,
against a surface loaded coil will drive the fibers and
dirt into the coil. This will make cleaning efforts more
difficult. Surface loaded fibers must be completely
removed prior to using low velocity clean water rinse.
Periodic Clean Water Rinse
A monthly clean water rinse is recommended for coils that are
applied in coastal or industrial environments to help to remove
chlorides, dirt and debris. An elevated water temperature (not
to exceed 130ºF) will reduce surface tension, increasing the
ability to remove chlorides and dirt. Pressure washer PSI must
not exceed 900 psig and the nozzel should remain at leat 1 foot
from the coil to avoid damaging fin edges.
Routine Quarterly Cleaning of Option E Coated Coil
Surfaces
Quarterly cleaning is essential to extend the life of an Option
E Coated Coil and is required to maintain warranty coverage.
Coil cleaning shall be part of the unit’s regularly scheduled
maintenance procedures. Failure to clean an Option E Coated
Coil will void the warranty and may result in reduced efficiency
and durability in the environment.
For routine quarterly cleaning, first clean the coil with the
below approved coil cleaner (see approved products list under
Recommended Coil Cleaners section,
Table 35
). After cleaning
the coils with the approved cleaning agent, use the approved
chloride remover (under the Recommended Chloride Remover
section) to remove soluble salts and revitalize the unit.
