Bard 8620-344 I Wall Mount UV-C LED Field Kit Instruction Manual
WARNING
Electrical shock hazard.
Disconnect the remote electric power supply or supplies before servicing.
Failure to do so can result in serious injury or death.
WARNING
Exposed moving parts.
Disconnect all electrical power before servicing.
Failure to do so can result in severe injury or amputation.
CAUTION
Sharp metallic edges.
Take care and wear appropriate protective devices to avoid accidental contact
with sharp edges.
Failure to do so can result in personal injury.
CAUTION
Ultraviolet band C (UV-C) 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, protect components with UV-resistant material such as aluminum foil, aluminum duct tape, metallic shields, etc.
Overview
The UV-C field-installed light kit utilizes UV-C LED lighting technology to sterilize and improve overall air quality within an occupied space. UV-C exposure is proven to damage the DNA of microorganisms and render them inactive aiding in preventing the spread of diseases.
Product Specifications
WARNING
UV-C exposure can cause burns to skin and damage eyes.
Ensure proper safety precautions are taken during installation.
A trained, experienced technician must install the UV-C field kit.
Personal Protective Equipment (PPE)
UV radiation is absorbed by clothing, plastic or glass. Once absorbed, the UV
radiation is no longer active. Wear UV goggles or face shield. Cover any
exposed skin with coats, gloves, etc.
UV-C band light spectrum is not visible to the eye.
NOTE: The health aspects associated with the use of this product and its
ability to aid in disinfection of environmental air have not been investigated
by UL.
NOTE: Color shift or chalking may occur without affecting structural properties.

Parts List
Installation
Field-supplied tools needed:
- Appropriate personal protection equipment, including gloves and safety glasses
- Electrical meter to verify power status
- Drill
- Phillips head screwdriver
- 5/16″ nut driver
Installation Procedure
-
Disconnect all power to HVACR unit. Use the meter to verify that power has been disconnected.
-
Open front doors and remove inner control panel cover.
-
Remove blower housing cover (large upper panel).
-
Attach two (2) magnetic clips to the UV light assembly (see Dimensions drawing on page 2).
-
Install UV light assembly onto wire channel to the right of the blower assembly with the attached magnetic clips (see Figure 1).
-
Route wires into control panel through upper right bushing as shown in Figure 1.
-
Connect red wire from UV light assembly to “NO” contact on the relay assembly (see Field Installation Diagram on page 7).
-
Determine unit supply voltage—located on the unit serial plate. Connect black wire from UV light assembly to:
(230V-1PH) − “L2”
(230V-3PH) − “L3”
(460V-3PH) − Terminal block
See Field Installation Diagram on page 7. -
Connect red wire from “COM” on relay assembly to:
(230V-1PH) − “L1”
(230V-3PH) − “L1”
(460V-3PH) − Terminal block
See Field Installation Diagram on page 7. -
Connect short orange wire from relay assembly to indicator light assembly.
-
Connect short black/white wire from relay assembly to indicator light.
-
Install relay and indicator light assemblies in control panel using self-drilling screws provided (see Figure 2).
-
Install door panel switch into panel switch bracket 113-909. Cut insulation away from top of control panel to allow clearance and install the door panel switch assembly using self-drilling screws as shown in Figure 3. Door panel switch acts as interlock safety device to disable UV light source upon removal of blower access panel preventing UV exposure.
-
Route orange wire into upper right control panel bushing as was performed in Step 6 (see Figure 1).
-
Route long orange wire from relay assembly through upper right control panel bushing and connect to “NO” contact on panel switch assembly.

Install UV Light Assembly and Route Wires
16. Seat spade end of orange wire from panel switch assembly under the “G”
terminal on low voltage strip assembly, then seat spade end of black/white
wire from coil on relay assembly under the “C” terminal on low voltage strip
(see Figure 4).
17. Wires can be dressed with provided zip ties or by tucking into wire
channels. Ensure wires are secured away from sharp edges and moving parts to
prevent damage.
Cover wires and plastic components within a distance of 6″ of the UV light
with foil tape to create a protective barrier from the UV light.
18. UV light will not function without blower panel installed because of door
panel switch (interlock safety switch). Do NOT press door panel switch with
blower panel removed as the UV source could become active and create UV
exposure.
Replace blower access cover (large upper panel). Adhere UV-C Warning Label
7961-963 to blower access panel.
Adhere “UV-C LED Light Bar Installed” Label 7961-622-0375 to unit serial
plate. (Serial plate is silver and located on the exterior of the unit cabinet
or on a service panel with “5253-039-
XXXX” printed in the lower right corner.)
19. Now that blower panel is installed, UV light operation can be safely
verified. Restore power to unit and provide a “G” call signal from the
thermostat. Operation can be confirmed if indicator light installed in Step 7
is ON in control panel. Do NOT attempt to look at UV source to confirm
operation!
20. Disconnect power to unit. Replace all inner and outer panel covers.
21. Restore power to unit.
