The health aspects associated with the use of these products and their ability to aid in disinfecting of environmental air have not been investigated by UL.

DUO-2000 INSTALLATION INSTRUCTIONS

INSTALLATION INSTRUCTIONS FOR DUO-2000 LAMP

NOTE: : Due to directional airflow installation options, the Healthy Home System 3×3 Product Brand Label is enclosed for proper upright placement at the field installation. The Duo-2000 installation is specific to direction of airflow and must be properly positioned when choosing up flow, downflow, or horizontal airflow application. Pay attention to directional air flow arrow for proper installation. The installation of the Duo-2000 may be on the return air side, supply air side, or above the AC-Coil in the supply plenum of the HVAC system. For best results, the HVAC air filter should be upgraded to a Field Controls High Efficiency FC8 or FC11 pleated media air cleaner. Do not locate the Duo-2000 within 24 inches (direct exposure) of plastic materials or air filters. UVC radiation will degrade many plastic materials over time with direct exposure. The Duo-2000 is designed to be installed on indoor HVAC forced air ducted systems. Do Not install outdoors. Product is not designed to be exposed to outdoor elements.

WARNING: Disconnect power to all equipment before beginning this installation! Refer to all warning and cautionary statements as given in the included main installation instructions!

WARNING: Make sure unit is unplugged before installing the lamp

1. The ballast is factory set to 120 VAC. The voltage can be changed in the fifi eld to 230 VAC by sliding the voltage selector switch in (Figure 1) to the 230 volt position. The plug must be replaced and wiring must be done to applicable electrical codes.
2. Remove the front electrical cover from the Duo-2000.
3. Do not touch the bulb lamp glass section with bare hands. Wear oil-free cotton type gloves when handling germicidal glass bulb.
4. Remove Lamp (LT015) from packaging and slide non-pinned end through grommet.
5. Loosen lamp clip and insert lamp so that the end of the lamp is inside the unit.
6. Tighten lamp clip using the brass knurl. Make sure the lamp clip tightens around the plastic part of the lamp and not the glass. See Figure 2.
7. Connect ballast to the four pins on the lamp using the connector. See Figure 3.
8. Wipe down the lamp with the supplied alcohol wipe.
   

DUO MODEL INSTALLATION INSTRUCTIONS

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 humidifier.

• 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 fiberglass 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 recommended.
At .09 cents per kilowatt hour, continuous lamp operation cost 10.5 cents per day. Cycling the UVC germicidal lamp on and offff degrades lamp performance much faster and shortens the fifi lament life.

Install the Duo unit:

• a. Remove front electrical cover by removing 2 sheet metal screws on sides.
• 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 flaps 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 2.
• f. The Duo models are configured for upward or horizontal air flow direction as shipped. If the direction of airflow in the duct is downward, the whole Duo unit may be rotated, so that airflow 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 filament life, see Figure 6.
  

MAINTENANCE

WARNING: Disconnect power to the transformer before commencing inspection and cleaning.

NOTE: Wear disposable, non-absorbent protective gloves prior to inspection procedure in case of accidental breakage of glass.

1. We recommend inspecting and cleaning the lamp at least every 6 months. Frequency depends upon the environment. Such as: the type of air fi lter, duration of use and replacement cycle.
2. To maintain maximum output intensity, replace the UV-Aire lamp annually. The lamp should operate continuously for maximum lamp life and light eff ectiveness.
3. Do not attempt to clean the catalytic aluminum substrate with cleaning solutions. The catalyst is radiated with short wave ultraviolet light during period of non-air fl ow and is self-cleaning. If there is build up blocking the catalytic cells, sit the unit on end, on a fl at surface, with electrical enclosure facing up. Use low-pressure, compressed air to blow the surface of the catalytic cells free of blockage.

CLEANING THE LAMP

WARNING: Disconnect power to the transformer or unplug the120V power cord before starting replacement procedure.
