E. PCO Media: Media shall consist of six-inch (nominal) non-metallic media with face area to
match casing opening, pleated at one pleat per inch (nominal), with a 40-200 nanometer TiO2
coating. PCO media shall be placed perpendicular to the air stream in the unit casing. Media
shall have an internal mechanism to eliminate the silica produced by the oxidation of ethanol.
F. UVGI Lamps & Ballasts: Lamps and ballasts shall be designed specifically to provide type-C
ultraviolet light with a wavelength at or near 2537 Angstroms. Lamps shall be non-ozoneproducing. Lamps shall be Teflon-coated to reduce breakage. Sufficient lamps shall be
provided and positioned center point through the media equidistant from edges so as to
achieve a minimum coverage of 9.5 milliwatts per square inch of UVC light, upstream and
downstream, across all exposed surfaces of the PCO media. Lamp UVC output shall not
drop below 9.5 milliwatts per square inch over their usable 12,000 hr life.
G. Electrical: Unit shall be configured to operate with 120V/1φ/60Hz electrical power. Unit shall
be provided with junction box for point of connection.
H. Racking System: The racking system shall be constructed as either a front – loading or side
I.
Loading design. Either system must show proof of conformance to ICB 2012, CBC 2010
and ICC AC – 156 (2010).
The catalyst and the racking system shall bear the OSP
certification number.
J.
Unit shall be m anufactured by Genesis Air, Inc. Model No.: 2008 PCP Compound or Owner
approved equal.
PART 3 - EXECUTION
3.01
INSTALLATION
A. Installation shall meet or exceed all applicable federal, state and local requirements,
referenced standards and conform to codes and ordinances of authorities having jurisdiction.
B. All installation shall be in accordance with manufacturer’s published recommendations.
C. Confirm the filters installation upstream of PCO system so there is no passage of unfiltered
to the PCO system. Any deficiencies found shall be brought to the attention of MDA for
necessary corrections. Each of the existing air handler air filter installations includes felt,
rubber and neoprene gaskets to prevent air around filters.
D. The PCO system supports and retention elements shall be coordinated to provide a
substantial, structurally sound, leak-proof installation.
E. Do not operate PCO system and air handling equipment without having all filters in place
and properly operating.
3.02
TESTING
A. Verify the proper installation of the PCO system. Thoroughly inspect for proper fit and seal of
all PCO panels.
B. A factory-trained representative shall supervise installation of the PCO system in the air
handling equipment and system Start-up.

C. The PCO system for each air handler shall be field tested in place by subjecting the
installed PCO system installation to a Smoke in a Can Test, Industry Standard for Testing
Smoke Detectors Particulate 0.3 – 2.5 micron ppm. Each system shall pass a test for the
following:
1. Confirm the AHU smoke detector trip setting with filtration only and starting with ten
second burst(s) with using (1) can of smoke, (2) cans of smoke, etc. with catalyst
turned off.
2. Repeat item 1 above and demonstrate the AHU smoke detector will not trip with
catalyst turn on with the same number of cans used a 10 second burst tests.
3. With the catalyst on begin emptying full can(s), 1, 2 or more cans, at the same time into
the air stream to a point where the smoke detector will trip. Record the smoke release
duration and the number of can(s) at the trip point.
4. Particulate reduction minimum of 95% with a MERV 14 Filter in place.
5. TVOC reduction minimum of 65%
6. AHU air speed through the unit PCO system shall be at its normal operating air flow
(max. 16,300 CFM). The unit airflow speed will not exceed 400 FPM.
7. Owner acceptance will be after receipt of written test reports indicating satisfactory
performance.
3.03
TRAINING
A. Provide minimum 4-hour instruction in system trouble shooting and preventative maintenance
to Owner.
B. Photo-catalytic oxidation air cleaning systems: A manufacturer’s authorized representative
shall visit the Project Site bi-annually for the first year of operation to inspect system and
