Safety
READ BEFORE OPERATING THIS UNIT
This unit should only be operated or repaired by personnel who have read this manual,
understand the unit’s operation, and know what to do in the case of an emergency. All repairs are
to be performed only by an authorized service technician.
Safety Warnings
ULTRAVIOLET (UV-C) EXPOSURE WARNING
Light in the short-wave UV-C band can cause erythema (reddening of the skin) and conjunctivitis
(inflammation of the mucus membranes of the eye). People should avoid direct exposure to UV-C.
UV-C exposure is relatively easy to limit because most products absorb UV-C. Standard windows
and glass absorbs all UV-C. Dead skin absorbs most UV-C light energy, so erythema is limited. UV-
C does not penetrate the eye’s lens. However, conjunctivitis can occur and, though temporary,
may be extremely painful. The manufacturer recommends that all direct exposure to UV-C be
avoided. Safety glasses must be worn at all times the device is plugged in; in addition, it is highly
recommended that a protective garment such as a lab coat is worn while operating the device. In
case of accidental UV-C exposure, contact appropriate EMS.
HIGH VOLTAGE HAZARD
The unit uses high voltages, and proper electrical connections are required. Do not operate the
unit if there is any visible damage to the body or any other part.
HOT SURFACE
UV Lamps will become hot during use and will remain hot for a brief period after use. Lamps
should not be touched for at least 2 minutes after use.

Safety Features
DC Series fixtures incorporate low pressure mercury arc ultraviolet lamps that emit UVC energy
that is harmful to the eyes and skin. Follow manufacturer’s installation instructions carefully to
ensure fixture is installed in a manner which prevents any direct exposure of eyes or skin to UVC
light. Before installing or servicing this unit, make sure that all power is off, to prevent electric
shock and/or accidental exposure of eyes or skin to UVC.

Installation
Installation of the DC Series lamp fixture should be performed by an HVAC professional.
DO NOT MOUNT THE DC SERIES LAMP FIXTURE IN A VERTICAL ORIENTATION
DC Series lamp fixtures can be installed anywhere in the HVAC system. For coil applications, place
the lamps in a position downstream from the coil.
Reflective aluminum can be installed in the interior of the housing where the lamps will be located
for increasing the intensity of the energy field. Reflecting the UVC energy is helpful but not
required.
DC Series models are supplied with an eight (8) foot 120-volt standard three prong power cord, so
the proximity of an available power source should be considered when selecting the mounting site
of the fixture.
1) After determining the best position for the DC Series unit, a clearance hole must be made
for insertion of the lamp/support assembly. Clearance hole dimensions for the
lamp/support assembly are unit specific. See below chart for details.

2) Once clearance hole is made, locate mounting holes by one of the following methods:
a. place the housing assembly against the exterior wall and use it as a template for
transferring the mounting holes. The mounting holes can be pilot holes for sheet
metal screws (see Figure 1).
b. use the below chart and illustration to locate mounting holes

 Open enclosure and remove adhesive gasket. Clean mounting surface of enclosure and
apply gasket flat / not covering any hole plugs, if applicable. See Figure 2 for proper gasket
placement. Replace enclosure cover.
4) Fasten the housing securely into place using sheet metal screws.
5) The UVC lamp(s) will be shipped in a separate container. Carefully remove the lamp(s) from
their packaging. Clean cotton gloves should be worn when handling the lamps to ensure
that no skin oils or other contaminants are left on the lamp(s).

6) A 4-pin lamp socket is included inside the housing. Move the lamp socket to the side to
allow for the UVC lamp to be inserted. Loosen hex nuts and slide larger section of keyhole
slot in lamp clip over lamp clearance hole in chassis. (see Figure 3)
7) Carefully insert lamp. Make certain the end of lamp inserted through chassis comes to rest
in retaining bracket holes on far end of fixture. Use of the additional guide bracket
(provided on certain models) is recommended in fixtures using longer lamp lengths.
8) Slide lamp clip over so the narrow portion of the keyhole slot captures the lip on lamp
base, holding the lip between the lamp clip and the chassis. (see Figure 2)
9) Carefully tighten hex nuts down to hold lamp in place. DO NOT OVERTIGHTEN AS THIS
WILL CRACK THE LAMP BASE.

10) Connect lamp socket to lamp base, making certain to seat base and socket firmly together.
Repeat for additional lamps. (see Figure 4)

11) Replace the exterior cover of the DC Series housing and secure it into place with the
supplied hardware.
12) Power can then be applied by plugging the 120-volt power cord into the nearest power
receptacle. Cable clamps or other means of supporting the power cord can be used if
desired.
The UVC lamps will come on instantly with the power being applied. For best results, leave the DC
Series lamps on continuously.
NOTE:
The included warning label “WARNING, DO NOT LOOK AT UV LIGHT” to be applied to duct
near DC unit location.

Maintenance
The DC Series requires very little maintenance.
xReplace all lamps annually – for 33” & 45” units the enclosure will need to be
removed from the duct.
xClean any material or deposits on the lamps or unit casing.
xConfirm support tube hardware is adequately tightened.
xVisually inspect the unit for damage prior to installation. DO NOT use if there is
damage.
Troubleshooting
ALWAYS DISCONNECT POWER TO FIXTURE PRIOR TO SERVICING!
Issue Resolution
The unit has lost power 1) Verify the fixture is connected to proper electrical input
2) Verify plug on unit power cord is fully engaged in
electrical socket
Lamps will not come on, but
there is appropriate power
to the unit
1) Verify lamps are fully seated in lamp sockets
2) Replace lamps
3) Replace ballast
One lamp doesn’t come on
(in a 2-lamp unit)
1) Verify non-functioning lamp is fully seated in lamp
socket
2) Replace lamp
If none of the above resolve the issue, please contact the manufacturer or a certified distributor to
schedule a maintenance call to repair the equipment.
