General

Germicidal lights emit ultraviolet (UVC) energy that has been proven effective in reducing microbial life forms (viruses, bacteria, yeasts, and molds) in the air. UVC germicidal lamps greatly reduce the growth and proliferation of mold and other bio-aerosols (bacteria and viruses) on illuminated surfaces.
Germicidal lamps are NOT intended to be used for removal of active mold growth. Existing mold growth must be appropriately removed PRIOR to installation of the germicidal lamp.
A door switch is provided which de-energizes the UVC light when the door is opened.
IMPORTANT – Cotton gloves or a cotton cloth must be used when handling the new UVC lamp.

Application

The UVC light kit is specifically designed for LG/LC/KG/KC/KH 156-300(S) units. In addition, the light is equipped with shields to focus the UVC light on the coil surface where it is needed and reduce the exposure of light on other components and access panels for improved safety and overall effectiveness.
Enhanced rapid start ballast provides UVC lamp operation at a full range of operating conditions.
Lamps operate on 110-230V single‐phase power supply. A step‐down transformer may be ordered separately for 460V and 575V rooftop units (factory-installed in
LGM/LCM). Alternately, 110V power supply may be used to directly power the UVC ballast(s).
WARNING
Potential Mold Spore Release.
Application of UVC lamps to existing mold growth can cause respiratory irritation and allergic symp toms.
Do not use UVC lamps where active mold growth ex ists. Remove active mold growth from surfaces prior to operation of UVC lamps.
NOTICE
Potential odor emissions.
Odors may be present when some materials are ex posed to UV light.
These materials may include Technicoated or ECoated Coils. Other materials may include chemi cals, solvents, polymers and organic materials.
Some occupants may notice irritation or discomfort. If odors are present, the UV Lights should be turned off and fresh air should be introduced into the occu pied space immediately. Contact your Independent Lennox Dealer.
CAUTION
Potential Risk of Degradation of Materials.
Potential of degraded wire insulation may cause hu man injury through electrical shock.
UVC light may damage plastics and rubber materi als. May cause fabric discoloration.
Avoid UVC light exposure to plastic drain pans, wire insulation, flex duct or other plastic/rubber compo nents.
Before installation, confirm that any corrosion‐re sistant coating (if applied to the coil) will not be nega tively impacted by the UVC light exposure.

Turn off power to the rooftop unit.
Open access to the control box, blower compartment and the filter section.

WARNING
Electric shock hazard.
Can cause injury or death.
Disconnect all remote power supplies before opening any unit access panels. Unit may have multiple power supplies. Do not operate without access panels in place.
UVC Exposure Protection
The UVC light is equipped with a unique directional shield to focus the UVC light on the coil surface and drain pan where it is needed and reduce the exposure of light on other components such as wiring, plastic parts etc. For shielding of electrical wiring in the rooftop unit, black convoluted tubing is provided in the unit. However, if there is any concern, aluminum foil tape can be used to cover up any exposed component.
WARNING
Potential Risk of Fire.
Dust, lint and other debris may cause fire if allowed to come in contact with illuminated UVC lamp. Remove any dust, lint or other debris from lamps and surrounding duct system.

Install UVC Light Assembly

The lamp for the UVC light assembly comes separately packaged in a foam sleeve. Install the lamp in the UVC assembly before installing it in the unit.

Wear cotton gloves or use a cotton cloth when handling the new lamp. To install the lamp, remove two black plastic splash guards from the lamp holders on each end of the UVC assembly. Gently but firmly push in the splash guards on each end of the lamp. See figure 1.
Align and insert the splash guards (now connected to the lamp) back onto the UVC assembly lamp holders. Click into place.
Carefully place the UVC assembly on the blower deck. Line up the mounting holes on the UVC assembly with the mounting holes on the blower deck. See figure 2. Use the self tapping screws provided to secure the UVC assembly in place.

Wiring Connections

Route the UVC cable wires as shown in figure 3.
Wire tie the cable at multiple locations along the existing wire harness.
Make wiring connections in the control section as shown in:
Figure 4 – 230V LGH/LCH/KG/KC/KH with T1
Figure 5 – 460/575V LGH/KG with T49
Figure 6 – 575V LGH/KG with T13
Figure 7 – 230V LGM/LCM
Figure 8 – 460/575V LGM/LCM

Install Convoluted Tubing

Install convoluted tubing (included in the kit) to shield electrical wiring and components. The tubing is split type making it easy to slip on the wiring. Black wire ties are provided to tie the tubing in place. See figure 9 and 10.
In addition, aluminum tape (not provided) can be used if needed to further shield any other surface of concern.
Note – The cable should not extend past the UVC assembly to be in direct line of sight of UVC lamp. Install UV Shield
To block the UVC light from reaching the filter access door, install the sheet-metal panel. See figure 11.
Install Door Switch
Install the door switch bracket onto the UV shield. Clip the switch onto the bracket and wire as shown in figure 3. Finish Installation
Close all access doors before powering UVC lamp. Apply UVC Danger label and UVC Field Kit label to blower access door so that it is clearly visible. See figure 12.
Configure M4 For UVC Light

Use the following mobile service app menu to configure the Unit Controller. SETUP > INSTALL > RTU INFORMATION > CONFIGURATION ID2
Set position 6 to to the appropriate setting to enable the UVC:
2=UV Lamp Only Installed
3=Both UV Lamp and Ionizer Installed

M3 Unit Controller Configuration
Configure the Unit Controller to enable the UVC Lamp using the following menu: SETUP . INSTALL
Navigate through the various setup questions until Configuration ID 2 appears. Set position six to the following to enable the UVC feature:
1=UV Lamp only installed
3=BOTH UV Lamp and Ionizer installed.

Operation

For optimal performance, continuous operation of the UVC germicidal lamp is recommended.

Maintenance

For all maintenance, contact a licensed HVAC technician. If UVC lamp does not come on:

Check Power Wiring: Disconnect 1/4” QC (quick connects) of the UVC cable near the UVC assembly.
With Power ON, use multimeter to test 110-230V at the 1/4”QC quick connects from the control panel.
Check Lamp: Carefully remove the UVC assembly out of the rooftop unit. Use multimeter to test for continuity across each pair of pins at each end of the lamp.
Check Lamp Installation: Make sure that lamp’s pins snap properly into the lamp holder.
