PCO/UV N-Duct™
Model
Installer’s Manual

AirGorilla™ combines the power of two highly regarded contaminant fighting technologies -
ultraviolet light and PCO (photocatalytic oxidation). The PCO/UV N-Duct™ utilizes two,
Dual-Radiant™ germicidal ultraviolet lamps that produce a total of 210 microwatts of
contaminant killing power (measured at 1 mtr.). In addition, the UV lamps illuminate a
unique photocatalytic filter of nano-technology titanium dioxide that provides higher levels of
destruction and on a broader range of contaminants. As air circulates through the air duct
system and passes the PCO/UV N-Duct™ unit, these powerful technologies destroy
airborne bacteria, mold, fungi, viruses, volatile organic compounds (VOC's) & odors.
AirGorilla’s PCO/UV N-Duct™ unit is designed for ease of installation and service. Cut just
one hole and install. The unit never needs to be “un-installed” to replace the UV lamps.
Simply open the door and change them out. And thanks to the innovative Display Panel and
micro-circuitry, there is no guesswork if the UV lamps are working or if they need to be
replaced.

AUDIBLE ALERT – the PCO/UV N-Duct™ unit is often installed
in areas not readily visible to the owner and therefore the Replace
Lamp LED may not be seen when lit. When the UV lamps need to
be replaced, an audible alert will also be sounded (a continuous
beep) to notify the owner of the need to replace the lamps.

The PCO/UV N-Duct™ unit is designed for air disinfection and installs into the air handling
system or ductwork. Select a mounting location that offers sufficient space for the mounting
plate 7” x 13” and enough internal space for the UV lamps and PCO filter 11” H x 17” D. In
addition, allow for sufficient space for removal (pulling out) of an 18” UV lamp. Installation
also requires access to 120 – 277 VAC electrical power.
• Do not install where UV lamp is visible • Do not install in outdoor applications
• Do not expose wiring or plastic to UV light • Do not install beneath a humidifier
• If installed near an air filter, check with the filter manufacturer for UV properties & safety.

IMPORTANT
This unit must be installed in compliance and in accordance with all national,
state, and local electrical and mechanical codes. Failure to do so will void all
expressed or implied warranty representations.

ØThe unit should be installed perpendicular to the airflow so that air passes the UV
lamps first.
Airflow
Airflow
ØWhile the unit can be installed in either the return or supply air side, it may be
more effective in removing airborne contaminants if installed on the supply side.
ØOnce a mounting location is selected, use the included Mounting Template to
mark the location of the mounting plate screw holes and Lamps/PCO Filter
insertion hole (center this hole in the duct if possible).
ØDrill screw holes and cut insertion hole (make sure surfaces are flat and burr
free).
ØInstall unit into duct securing with sheet metal screws.
ØOpen Display Panel door and insert UV lamps into UV lamp portals (swivel lamp
retaining clamps out of the way then return when lamps are inserted).
ØAttach white lamp socket to 4 pins on lamp base (the lamp socket is asymmetrical
and can only be attached one way – rotate socket so holes align with base pins).
(If installing into ductboard, the unit can be secured with duct tape or by making 2
sheetmetal brackets 1” x 10” and securing the unit to the brackets with screws/nuts –
another “work hole” must be cut in the duct to allow access to attach the brackets to
the mounting plate.)
CONNECT POWER
The PCO/UV N-Duct™ unit is a variable voltage device and is designed for use with
120 – 277 VAC. The unit can be plugged into any 110 VAC electrical outlet, or by cutting the
plug off the powercord can be wired into any AC source so that the unit is “ON” continually;
or wired directly into the HVAC control panel so that it operates when the HVAC system is
running.
Once the unit is connected to an electrical power source it should be fully operational. The
PCO/UV N-Duct™ unit has a “kill” switch activated by the Display Panel door. If the door is
open, power to the electrical functions of the unit are shut off. The Display Panel door must
be closed for the unit to operate. If the unit is receiving power and the Display Panel door is
closed, the Power On LED should be lit as well as the 2 LEDs indicating the UV lamps are lit.
CHECK UNIT OPERATION
4

1) Power On light is not lit
-Ensure the unit is receiving power (unit is wired correctly or plugged into an
active AC outlet)
-If wired into the HVAC control panel, HVAC unit must be running
-Ensure Display Panel door is closed completely
2) UV Lamp On light is not lit
-Check that the lamp socket is firmly attached to the lamp base pins
-Ensure the wires to the lamp socket have not become dislodged
-Ensure the UV lamp is operational (open the Display Panel door; pull the UV
lamp out slightly so that the lamp glass can be seen; deactivate the “kill
switch” by depressing the kill switch button; if UV lamp does not light, replace
lamp – UV resistant safety glasses should be worn for this test)
Like all light bulbs, UV lamps have a life span. Unlike regular light bulbs, however, UV lamps
loose their effectiveness over time. Typically, after 9000 hours of use (approximately 1 yr.),
the lamps do not produce enough ultraviolet germicidal irradiation to be effective. However,
even after this time, the lamps usually do not burn out, but stay lit. This is often confusing
to owners, but the lamps simply no longer produce the intensity necessary to be effective in
improving or maintaining indoor air quality and must be replaced. It should also be noted
that some ultraviolet lamps burn out prematurely and do not last the full 9000 guaranteed
hours. AirGorilla’s visual and audible reminders of when the UV lamps need to be replaced
(or if they have burned out) help ensure you are receiving the full benefit and effectiveness
of the PCO/UV N-Duct’s™ advanced air cleaning technologies.
WARNINGS

TROUBLESHOOTING
ULTRAVIOLET LAMP LIFE
WARNING
Electrical Shock – The PCO/UV N-Duct™ system is to be wired or plugged into 110 –
240 VAC electrical power.
Ultraviolet Light is Harmful – Never look at a lit ultraviolet lamp without UV protective
glasses and skin coverings. Unplug the lamp before servicing.
Ultraviolet Lamp May Cause Injury – Ultraviolet lamps are made of glass and
therefore somewhat fragile. Safety glasses and gloves should be worn when handling a
UV lamp. In addition, UV lamps can be very hot and cause skin burns. Allow lamp to cool
before handling.

Steps for Replacing the Ultraviolet Lamps:
1. READ THE WARNINGS ABOVE.
2. If the unit is plugged into an AC outlet, simply unplug it before servicing the UV
lamps.
3. Open the Display Panel door. The Display Panel door is connected to a kill switch
that disables power inside the unit when the door is opened.
4. The unit contains 2 UV lamps. The base of the UV lamps (white in color) are visible
on the left side of the enclosure. Attached to each lamp base is a white socket with
wires leading to the power supplies that are housed to the right (separately
enclosed). Pull the lamp socket off the UV lamp base.
5. Each lamp base is held in a cavity by two swivel clamps. Simply swivel them out of
the way. Grab the lamp base and pull it toward you gently. The lamps are held snug
so a little force may be necessary to pull them out. The lamps are 16” long.
6. Install new, replacement lamps (AirGorilla #DR36-1).
a. Make sure lamp is clean – use alcohol wipe to remove dirt and fingerprints.
b. Insert UV lamp into UV lamp portal.
c. Turn swivel clamps over lamp base to hold secure.
d. Attach lamp socket (align holes in socket to lamp base pins).
7. Push the “Reset” button next to the lamp (there is a reset button for each lamp) that
restarts the 9000 hour timer that alerts you when the lamp reaches the end of its
effective life.
8. Close the Display Panel door. Plug in the power cord if applicable. Within a few
seconds, the LED lights that indicate POWER ON and AIR PURIFYING should be lit
(not the REPLACE LAMP LED).
9. If the correct LEDs are not lit, reopen the Display Panel door and make sure the lamp
socket is attached fully to the lamp base pins, then make sure the Display Panel door
is closed completely. If the LED lights are still not lit, consult the TROULESHOOTING
SECTION ABOVE.
