5. Thoroughly clean the contaminated area with mild
bleach and water solution or an EPA-approved
sanitizer specifically designed for HVAC use.
Carefully follow the sanitizer manufacturer instruc-
tions regarding the use and the disposal of their
product.
6. Immediately rinse the drain pan thoroughly with
fresh water to prevent potential corrosion from the
cleaning solution of the drain pan and drain line
components.
7. Allow the unit to dry thoroughly before putting the
system back into service.
8. Determine and correct the cause of the microbial
contamination.
9. Be careful that the contaminated material does not
contact other areas of the unit or building.
Properly dispose of all contaminated
materials and cleaning solution.
IMPORTANT: Standing water in
drain pans can promote microbial
growth (mold) that may cause unpleas-
ant odors and serious health-related
indoor air quality problems. If mold is
found, it must be removed immediately
and that portion of the unit properly
cleaned and sanitized.
Air Filters
Catalog data tables provide filter size, type and
quantity.
Throwaway Filters
To replace throwaway lters, install new lters with the
directional arrows pointing in direction of airow.
Fans
Inspecting and Cleaning Fans
Fan sections or air handlers should be inspected every
six months at a minimum or more frequently if operating
experience dictates. Accumulated dirt and organic
matter on the interior surfaces of fans should be cleaned
immediately. The suggested procedure for cleaning
these surfaces is:
1. Disconnect all electrical power to the unit, tag and
lock out power source.
2. Put on appropriate personal protective equip-
ment.
3. Use a portable vacuum with HEPA ltration to
remove the loose dirt and organic matter. The lter
should be 99.97% efcient at .3 micron particle
size.
4. If no microbial growth (mold) exists, thoroughly
clean the fan and associated components with an
industrial cleaning solution. Carefully follow the
cleaning solution manufacturer instructions regard-
ing use and disposal of their product.
5. If microbial growth (mold) is present remove the
contamination, and thoroughly clean the affected
area with an EPA-approved sanitizer specically
designed for HVAC use. Carefully follow the
sanitizer manufacturer instructions regarding the
use and disposal of their product.
6. Rinse the affected surfaces thoroughly with fresh
water and a fresh sponge to prevent potential cor-
rosion of metal surfaces.
7. Allow the unit to dry completely before putting it
back into service.
8. Use caution to assure that any contaminated ma-
terial does not contact other areas of the unit or
building.
Properly dispose of all contaminated
materials and cleaning solution.
IMPORTANT: If the microbial growth
(mold) was found, the cause of the
contamination must be determined
and action taken to assure it does not
reoccur.
