Made in USA
NOTE: Read this entire instruction sheet before starting the installation.
IMPORTANT CONSIDERATIONS
Improper installation, adjustment, alteration, service,
maintenance, or use can cause fire, electrical shock, or
other conditions which may cause personal injury or
property damage. Consult your supplier or Steril-Aire for
information or assistance.
Understand the signal words DANGER, WARNING, or
CAUTION. These words are universally used for overall
safety. DANGER identifies the most serious hazards
which will result in severe personal injury or death.
WARNING signifies hazards which could result in
personal injury or death. CAUTION is used to identify
unsafe practices resulting in minor personal injury or
product and property damage.
WARNING: Before performing maintenance or
service on fixture, ensure unit is unplugged.
Electrical shock can cause injury or death.
CAUTIONS:
Never expose eyes or skin to UVC light.
Wear gloves, face shield/glasses (per ANSI
Z87.1) and cover all exposed skin.
Do not touch Emitter glass without gloves.
Damage to Emitter may result. Oil from
fingerprints will permanently etch glass of
Emitter and weaken structure. If necessary,
clean Emitter using a Steril-Aire cleaning kit
(isopropyl alcohol and a lint-free wipe may
be substituted).
Voltages outside of the range designed for
the unit will void the warranty and do
permanent damage to the entire unit.
Emitter contains a small quantity of mercury.
If an Emitter breaks, clean and dispose of
with care.
UVC energy may cause damage to non-
metallic components except for UV-rated and
HVAC-style drain pans. Select mounting
locations that prevent exposure to
vulnerable components. If mounting
locations are limited, such components shall
be protected with UV resistant material such
as aluminum foil, aluminum duct tape,
metallic shields, etc.
The qualified installer must use factory kits
and accessories when installing this
product.
INSTALLATION &OPERATION
NOTE: ENSURE THAT EMITTER IS INSTALLED BEFORE
POWER IS APPLIED. INSTALLING EMITTER AFTER
POWER HAS BEEN APPLIED WILL TRIGGER THE “END-
OF-LAMP-LIFE CIRCUIT” AND THE EMITTER MAY FAIL TO
LIGHT. IF THIS HAPPENS, SHUT OFF POWER FOR 10
SECONDS AND THEN TURN POWER BACK ON. EMITTER
WILL THEN LIGHT.
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.
2. For unitary air conditioners and smaller air
handler units, disconnect power from unit. For
larger units, the Emitter access door or panel
should be interlocked with the power source to
turn Emitter(s) off when the system is opened. It
should have signs (provided) in appropriate
languages alerting maintenance personnel to

2
the possible hazard of looking at or exposing
skin to UVC energy. Service accesses may be
equipped with a glass or Lexan® window
(viewport) to view Emitters. UVC energy does
not penetrate common glass or Lexan®.
3. If applicable, remove outer cover of unitary air
conditioner or air handler.
4. UVC energy may damage some plastics except
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 the UVC energy.
6. Determine location of the Emitter. (Many types
of unitary air conditioners have a removable
shroud/heating coil assembly that may
adequately accommodate the Emitter.) The
Emitter shall:
oBe at least 1” away from the heating coil.
oNot make contact with the blower.
oProvide direct light onto the cooling coil and
drain pan.
oBe positioned so there is no direct, visible
light from outside of the unitary air
conditioner. A baffle may be installed to
provide any needed light blockage.
CAUTION: Do not drill into coil, refrigerant lines
or other mechanical equipment.
7. Determine an appropriate flat-surfaced location
for mounting the power supply with the provided
screws. Make sure that the power supply’s lead
socket (with extension cord, if applicable) can
reach the pins of the Emitter and that its wires
can reach the power source; mount the power
supply.

8. Based on the mounting option selected, use the
following instructions for installation. Install the
Mounting Bracket(s) and Emitter.
oSpring Clips: Mount clips on existing panel
facing the coil. The clips should be attached to
the Emitter on both ceramic ends. If the spring
clips must contact the Emitter glass, 3 wraps of
electrical tape are recommended at the points
of contact to prevent the spring clips from
damaging the Emitter wires along the lamp. If
the wires running the length of the lamp have
been damaged, the warranty is void.
Short Hooks: Remove spine/top plate between
the two upper coils. Cut spine/top plate in order
to accommodate the support wire. Insert the
short hooks over the top of the cooling coils
such that its right angle leg slides between the
fins of the front coil (see below). Ensure that
Emitter ceramic ends rest on the Short Hooks
(see below).
Reinstall the spine/top plate pieces. In some
cases, one Short Hook may be sufficient where

the collared Emitter end can rest in a 13/16” or
7/8” hole drilled on a panel between the coils
and blower wheel on the end of unit (see photo
below).
oFlat Plate Lamp Holder (for metal):
Connect the socket from the power supply
or extension cord to the Emitter pins. Plug
power supply’s power cord into outlet.
Reconnect power and replace outer cover
of the unit. Refer to the images below for
guidance.
oFlat Plate Lamp Holder (for plastic)
Make a ¾” hole in the plastic external
housing or internal plastic plate in the unit.
oInsert Lamp Holder: Drill 1-1/4” hole on a
panel to accommodate component A and
secure A with screws. Slide Emitter partially
through A. Slide component B (collared end
first) onto power supply’s cord or extension
cord and install cord onto Emitter pins (see
Photo 1). Slide Emitter and component B
through A, and twist and lock B under A’s
tabs (see Photo 2).
oU Bracket:
Connect the socket from the power supply to
the Emitter. Snap the Emitter’s ceramic ends
into the spring clips of the U Bracket. Lower
the bracket and Emitter into the desired space
until the Emitter is appropriately facing the
cooling coil. Affix the bracket’s straps onto the
mounting surface with the provided hex
screws.

9. Connect the socket from the power supply or
extension cord to the Emitter pins.
10. Complete all power connections.
11. Reconnect power to the air conditioner. The
Emitter should emit a bright blue hue, indicating
that it is working properly.
12. Replace outer cover of air conditioner.
MAINTENANCE
Emitters need to be periodically replaced to maintain
design output. The change-out basis depends upon
the application, number of times switched on/off per
day, and the hours of operation. Emitters are to be
replaced when output falls to 50% of initial output (or
as specified) by actual radiometer measurements. A
Steril-Aire UVC Radiometer Kit may be used for
such measurements. If a radiometer is unavailable,
Emitters should be replaced after 9,000 hours of
use.
TROUBLESHOOTING
Symptom
Possible Causes
Corrective Action
Emitter does not light
Momentary loss of power
Reset Power Turn off power for 10 Seconds, and then
turn power on.
Poor connection
Check connection to Emitter. Check wiring
connections. Reset Power.
Incorrect wiring
Inspect circuit to wiring diagram.
Dirty pins
Clean pins. Reset Power.
System malfunction
Check system components, interlock door switches,
relays, motion detectors, etc.
Emitter reaching end of life
Replace with new Emitter. Reset Power.
Defective Power supply
Replace Power Supply.
Low Radiometer Reading
or Visibly Weak Emitter
Light
Dirty Emitter or Radiometer
Clean Emitter. Clean Radiometer lens.
Bad Wiring
Check wiring to Emitter.
Emitter reaching end of life
Replace Emitter.
Emitter too Cold
If emitter is at or below 35°F (1°C), Emitter is too cold
to operate properly.
Red/Orange Emitter
Emitter reaching end of life
Replace Emitter.
REPLACEMENT OF EMITTERS
1. Turn off power to the kit.
2. Carefully pull and slide out the Emitter from the
black shrink wrap. Carefully remove Emitter. DO
NOT CUT THE BLACK SHRINK WRAP.
3. Single Ended Emitters must be installed with
silicone grease applied to the female lead
socket. Without silicone grease moisture can
enter the socket and damage the socket, voiding
the warranty.
4. Using a new Emitter and grasping only the
ceramic ends, align the Emitter pins with the
slots on the inside of the black shrink wrap and
carefully push the pins into the slots until seated.
The Emitter is now safely locked into place.
5. Once the kit is powered, the Emitter should emit
a bright blue hue.
