Inspecting and Cleaning the Internal Insulation on Fan-Coils

The process of cooling and dehumidification produces condensate (water) which must be continuously removed from the air handling unit. The entering air side of the cooling coil to the leaving edge of the drain pan is considered to be the “wet” section of the unit. Other potentially “wet” sections are immediately downstream of a humidifier and/or an fresh air intake section.

It is common for the “wet” section components, including the internal insulation, to become wet during normal operation. Therefore, inspect the internal insulation in these areas periodically to assure it is clean and free of dirt or microbial growth (mold). Inspect units every six months or more frequently if operating experience dictates. Accumu- lated dirt and other organic matter exposed to water or extended periods of high relative humidity (60% or higher) may support micro- bial growth. Clean the insulation to prevent the unit from becoming an IAQ contaminant source.

Also, inspect internal insulation in the “dry” areas of the unit periodi- cally to ensure the insulation is clean and dry. Wet insulation in an area that is normally considered to be “dry” may indicate an opera- tional problem. Refer to Table 40 on page 99 for further information. Inspect the equipment a minimum of every six months or more frequently if operating experience dictates. When accumulated dirt and other organic matter is exposed to water or extended periods of high relative humidity (60% or higher) may support microbial growth, an indoor air quality contaminant source.

If evidence of contamination exists in either the wet or dry sections, take immediate action to determine and eliminate the cause. Remove the contamination and sanitize the affected area. See Tabale 40 on page 99 for assistance in identifying the cause. Remove and clean any microbial growth on a non-porous insulating surface (e.g. closed- cell insulation or sheet metal surface).

The Trane Company recommends the following procedure for proper cleaning the fan-coil internal insulation and sheet metal:

1.Disconnect all electrical power to the unit.

2.Don the appropriate personal protective equipment (PPE).

3.Thoroughly clean the contaminated area(s) with an EPA-approved sanitizer specifically designed for HVAC use. Use a brush for sheet metal surfaces or a soft sponge on closed-cell foam surface to mechanically remove the microbial growth. Be careful not to damage the non-porous surface of the insulation. Carefully follow the sanitizer manufacturers instructions regarding personal protection and ventila- tion.
