Fans:
Fans and blowers shall be thoroughly cleaned. Areas
to be cleaned include blowers, fan housings, plenums
(except ceiling supply and return plenums), scrolls,
blades, or vanes, shafts, baffles, dampers and drive
assemblies. All visible surface contamination depos-
its shall be removed.
Fans, motors, electrical components, and internal
casing should be cleaned with the use of a soft brush,
e.g. paintbrush, and vacuum cleaner. Brush out dirt
and dust etc. from the motor, fan impeller, fan casing
and shafts.
Use a vacuum cleaner and brush to remove dust
from the motor ventilation holes to ensure that motor
cooling is maintained at maximum efficiency. Don’t
use cleaning materials over the motor and wiring.
Belts should be checked for wear and tension and-
should be adjusted or replaced if necessary.
Air Diffusers:
Air diffusers may be cleaned with hot soapy water
and a soft cloth.
Attenuators:
If there is any evidence of damage, deterioration, de-
lamination, friable material, mold or fungus growth, or
moisture such that fibrous glass materials cannot be
restored by cleaning or resurfacing with an accept-
able insulation repair coating, they shall be identified
for replacement.
If you need to take one of the attenuators
a. Pull out the striping on the panel-profile cross sec-
tion part.
b. Take the panel out.
c. Take the screws on the profiles which are fixing the
attenuators out
d. Take the attenuators out
Cleanliness Verification:
Following cleaning, a visual inspection of interior sur-
faces, shall be performed to verify the surfaces are
visibly clean and free from non-adhered substances
and debris.
Verification of cleanliness will be determined after
mechanical cleaning and before the application of
any treatment or introduction of any treatment-relat-
ed substance to the AHU, including biocidal agents
and coatings.
Visual Inspection: The AHU shall be inspected visu-
ally to ensure that no visible contaminants are left.
1. If no contaminants are evident through visual in-
spection, AHU shall be considered clean; howev-
er, cleanliness of the AHU can be verified through
gravimetric or wipe testing analysis etc.
2. If visible contaminants are evident through visual
inspection, those portions of the AHU where con-
tam nants are visible shall be re-cleaned and sub-
jected to re-inspection for cleanliness.
Biocidal Agents and Coatings
1. Biocides can only be used if, under no circums-
tances, they are detrimental to the health of the
occupants in the areas served by the air handling
unit.
2. Biocidal agents shall only be applied if active fun-
gal growth is reasonably suspected, or where un-
acceptable levels of fungal contamination have
been verified through testing.
3. Application of any biocidal agents used to control
the growth of fungal or bacteriological contami-
nants shall be performed after the removal of sur-
face deposits and debris.
4. Biocidal agents shall be applied in strict accor-
dance with manufacturer’s instructions.
5. Biocidal coating products for both porous and
non-porous surfaces shall be water soluble solu-
tions with supporting efficiency data and MSDS
records.
6. Biocidal coatings shall be applied according to
manufacturer’s instructions. Coatings shall be
sprayed directly onto interior surfaces, rather than
“fogged” downstream onto surfaces. A continuous
film must be achieved on the surface to be treated
by the coating application. Application of any bi-
ocidal coatings shall be in strict accordance with
manufacturer’s minimum millage surface applica-
tion rate standards for effectiveness.
Upon cleaning completion, all components must
be returned to those settings recorded just prior to
cleaning operations.
Air-Volume Control Devices (dampers and any air-
directional mechanical devices) of the AHU, upon
completion, must be restored to their marked position
prior to cleaning.
