velocity clean water rinse.

2. Rinse. Do not use any chemicals (including those advertised as coil cleaners) to wash microchannel heat exchangers.

NOTE: 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. It is very important when rinsing, to water temperature is less than 55 °C. An elevated

water temperature (not to exceed 55 °C) will reduce surface tension, increasing the ability to remove chlorides and dirt.
