NOTE: Use of a water stream, such as a garden hose, against a surface loaded coil will drive the fibers, dirt, and salts
into the coil. This will make cleaning efforts more difficult. Surface loaded fibers must be completely removed prior to
completing low velocity cleaning and water rinses.
Required quarterly cleaning and chloride removal of Modine coated equipment (coil and cabinet surfaces)
