CAUTION
!
Other voltages will void the warranty and do permanent damage to
the entire unit. Fixtures should be operated continuously to preclude
the development of mold and bacteria.

p
CAUTION
!
Install Emitter tube before applying power. Failure to do so will
trigger the "end-of-lamp-life circuit" and the Emitter will fail to light!
If this happens, shut off power for 10 seconds, reinstall/install
Emitter and reapply power. Emitter will light.
2.1
Emitters™ (lamps) may be installed anywhere to
bathe an air stream or surfaces with germicidal UVC
enegy. It is best that they be located at known growth
areas such as downstream of the cooling coil and over the
drain pan or where best accommodates the system. They
may also be placed in a return air duct, supply duct, mixed
air plenum, point of delivery or any combination thereof to
suit the application.
2.2
When choosing the site, make sure that it can be
supplied with the necessary power requirements, and
suitable physical access for service.
2.3
Reflecting UVC energy is recommended as it
enhances irradiance. Lining the UVC cavity with aluminum
allows photons to bounce reducing possible shadow areas
thus increasing efficacy.
2.4
Permanently installed radiometers are the
recommended choice for monitoring the relative output of
a sensitive or large system for lamp changeout. In general,
UVC installations are sized to allow for an approximate
50% drop in total UVC output for mold control. Consult
factory specifications for infectious disease control.
3.1
Consult all applicable codes before installing.
Check fixture label(s) for the correct power requirements
and supply the correct voltage from a suitable, protected
(fused), and grounded power source.
3.2
The lamp access door or panel should be
interlocked with the power source to turn lamp(s) off when
the system is opened. It should have signs (provided) in
appropriate languages alerting maintenance personnel to
the possible hazard of looking at or exposing skin to UVC
energy. Service accesses may be equipped with a glass or
Lexan
®
window to view Emitters. UVC energy does not
penetrate common glass or Lexan
®
.
3.3
UVC energy may damage some plastics except
for UV rated and HVAC style drain pans. Wrap suspect
items with aluminum tape; use metallic conduit or use
other appropriate shielding where these items may be in
"line of sight" of UVC.
3.4
Determine the most desirable location for the
intended use and install reflecting material.
CAUTION: Do
not drill into coil, Freon lines or other mechanical
equipment.
3.5
Using the fixture base as a template, scribe and
then create one insertion hole, 1" diameter on the
mounting surface for the Emitter. Drill suitable holes for
each fastener (unless using self-taping screws). Using the
proper #10 fastener for your application, install fixture(s)
and wire in accordance with the applicable code.
3.6
Locate Emitter without touching glass with bare
hands and clean using a Steril-Aire Cleaning kit. Make
sure the "O" ring is toward and pushed onto the white
ceramic base of the Emitter. Release the holding spring on
the fixture base, lift it up and install the Emitter by grasping
the white base. Carefully push the lamp through the fixture
into the plenum until seated. Hold in and lock in place by
affixing the spring wire fastener to its lances. Push on the
power plug while noting the rectangle orientation of the
pins. Do not force. If the plug does not easily engage the
pins, rotate it 90 degrees.
3.7
Test all circuits and turn system on. A "blue hue"
will glow from each Emitter indicating that each fixture is
working.
Caution:
View
only
with all skin
covered and use a full face mask.
3.8
Affix the included "WARNING LABEL" in plain
sight to the A/C unit.
Protect labels against poor
conditions if necessary and replace when worn.
3.9
Emitters must be changed annually or sooner to
maintain design output. The interval depends on the
application, on/off switches per day and/or hours used. A
Steril-Aire UV Radiometer Kit can monitor UVC output to
determine lamp change-out.
3.91
Affix the included label for changing the emitter to
the outside of the housing.
4.1
Emitters should operate all the time. It is not
recommended to cycle the Emitters by time clock or fan
operation.
4.2
Emitters need periodic replacement to maintain
design output. The changeout basis depends on the
application, number of times switched per day and/or
hours of operation. Replace Emitter tubes when output
falls to 50% of initial output (or as specified) by actual
radiometer measurements.
4.3
If a radiometer is not available, Emitter(s) should
be replaced after 9,000 hours or in accordance with an
infectious disease application specification.
