WARNING: Never expose eyes or skin to UVC light from any source. Looking directly at the UVC light may cause permanent eye damage

or blindness.Never operate the Duo-2000 Air Purifying System out of the plenum. Avoid touching the glass portion of the lamp with your hands.

b. Hold or temporarily tape the included Ductboard Adapter Plate in the location chosen for installation,

and using the plate as a template,mark the mounting

surface using the outermost slots in the plate (see

Figure1).

Alternatively, a 5-3/8” square may be marked on the mounting surface.

c. Cut out the opening for the Duo unit in the mounting surface, making sure to cut slightly

outside the marked lines if the Ductboard Adapter Plate was used as a template.

d. If mounting the Duo unit on ductboard: attach the Ductboard Adapter Plate to the opening by

folding the inner ﬂ aps of the plate into the opening and fully back against the inside of the opening in

the ductboard, either from the sides or from top and bottom of the plate. Finish the Plate Adapter

installation by sealing around the edges of the plate to the ductboard, using mastic foil tape or other

material suitable for sealing duct joints.

e. Insert the Duo unit into the duct opening and attach it to the duct (or Ductboard Adapter Plate) with

the four included sheet metal screws. The wider side of the V-shape of the Duo

unit panels should face

into the oncoming airstream, see Figure

f. The Duo models are conﬁ gured for upward or horizontal air ﬂ ow direction as shipped. If the

direction of airﬂ ow in the duct is downward, the whole Duo unit may be rotated, so that airﬂ ow matches

Figure 5.

g. Reattach cover using 2 sheet metal screws previously removed in step 2a.

h. Attach the quick connect power cord and plug in to any standard 120 volt electrical outlet. Verify lamp

operation by looking through the view port on front cover. Continuous UVC germicidal lamp

operation is recommended. At .09 cents per kilowatt hour, continuous lamp operation cost 10.5 cents

per day. Cycling the UVC germicidal lamp on and off degrades lamp performance much faster

and shortens the ﬁ lament life, see Figure 6.

DUO MODEL INSTALLATION INSTRUCTIONS

1. Choose a location for the Duo unit, with the following considerations:

a. The Duo unit will reduce organic buildup on an HVAC cooling/heating coil by illumination with UVC

germicidal rays. Locate the Duo such that the maximum surface area of the coil is illuminated, while

installing as close to the coil as possible without damage to the coil.

CAUTION: Use care to avoid damage to the coil and any wiring or other components while installing the

Duo-2000.

WARNING: To prevent water damage or electric shock, do NOT mount unit under a humidiﬁ er.

b. The Duo unit may be installed on either the supply or return plenum.

c. The Duo unit may be installed in upﬂ ow, downﬂ ow, or horizontal ﬂ ow ducts and plenums.

d. The Duo unit may be installed directly onto a sheet metal air duct or plenum, or onto ﬁ berglass

ductboard when installed using the included Ductboard Adapter Plate (see Figure 4)

Attach the quick connect power cord and plug in to

any any standard 120 volt electrical outlet. Verify lamp

operation by looking through the view port on front cover.

Continuous UVC germicidal lamp operation is recom-

mended.

At .09 cents per kilowatt hour, continuous lamp

operation cost 10.5 cents per day. Cycling the UVC

germicidal lamp on and off degrades lamp performance

much faster and shortens the ﬁ lament life.

2. Install the Duo unit:

a. Remove front electrical cover by removing 2 sheet

metal screws on sides.
