Installation Steps for External Mounting of
Power Supply
:
1. Determine a suitable location to install unit
housing. Mounting location should be of
sufficient strength as to support the unit;
otherwise, reinforcement of the ductwork may be
necessary. Fasten the unit in place with four
self-tapping screws (supplied).
2. Select location for UV lamp module. Drill a 1”
hole. Mount mounting plate over drilled hole with
screws provided. Insert UV lamp module into
hole. Attach to HVAC system with 2 self-tapping
screws (supplied).
3. Plug lamp connector onto installed UV lamp
module. Be sure the connector is pushed fully
onto the lamp.
4. Connect power wires to the off 24 VAC HVAC
system.
This should be done in Accordance
with all State and Local Electrical and
Building Codes.
*Note: The T3 UV lamp assembly can be
removed independently, simply by removing the
2 screws in the gray lamp holder.
*3. Plug the rubber lamp connector fully onto the
installed UV lamp assembly. Be sure the 4
pinholes are orientated properly to the 4
matching pins on the lamp.
Note: The pins are in a rectangular pattern and
can only be mated in 2 positions
*Note: UV status viewport lens supplied to verify
lamp operation (for either installation). A 3/8”
hole will need to be drilled within a 3” radius
around the lamp, but above the “V” in the light
shield.

Installation Steps for Internal Mounting of
Power Supply
:
1. Mount power supply inside of the air handler
out of the air stream as much as possible.
Place the power supply as close to the control
panel as possible for ease of connecting to 24
VAC.
2. To utilize the internal mounting bracket- first
install the bracket inside the air handler in a
location that will position the UV lamp such that
it bathes the entire surface to be treated. Next
plug the lamp connector onto the lamp.
3. Connect power wires to the off 24 VAC
HVAC system.
This should be done in
Accordance with all State and Local
Electrical and Building Codes.
Maintenance
:
Note: It is recommended that this unit be installed
and maintained by a trained technician. Never
perform maintenance on the UV unit without
disconnecting power.
Typical maintenance consists of replacement of the
ultraviolet lamps.
UV lamps undergo a photochemical process during
operation. This slowly reduces the amount of UV light
generated to disinfect against airborne pathogens. For
optimum air stream disinfection against airborne
pathogens it is recommended the UV lamps be
changed on an annual basis.
When installing new lamps, ensure that the lamp glass
is free from any fingerprints or debris, as this may alter
the path of the UV energy. Use rubbing alcohol and a
dry cloth to remove any surface contaminants.
