Typical Installation Locations
The main unit is typically installed on the supply side duct just above the air system (upstream of a humidifier). It can also be installed on the return side if necessary.
Orient so the air flows past the UV light first before the carbon. Position the unit so the UV light does not shine directly on non-uvresistant materials (filters, humidifiers, flex duct, etc.). Ideally the UV light shines on the coil.
For dual systems select a remote UV light location that shines on the greatest surface area or the area with the most microbial growth.
Duct Mounting
-
Use gasket D to trace cut-line onto duct.
-
Cut hole in sheet metal or duct board.
IMPORTANT! Remove and dispose of cut-out piece of material. -
For sheet metal duct secure mounting plate C to sheet metal ducts using self-tapping screws **E .***
-
Remove paper backing from one side of gasket and fix gasket to the back of the mounting plate.
-
Remove paper backing from back of gasket then fix mounting plate and gasket to the duct.
-
Bend mounting plate flanges around the edges of the hole to secure mounting plate. For duct board use
tape on edges of mounting plate for air leaks and additional hold.
- To install without backing plate use (4) self-tapping screws.
Main Unit & UV Lamp Mounting
-
Fit the Main Unit through hole in duct. If attaching directly to metal duct use (4) Self-tapping Screws. If the Backing Plate is used fit the unit over the threaded posts and use (4) Quick Nuts G to secure it.
-
Insert AKTIV8 Lamp.
-
Mount UV Lamp using (2) Quick Nuts and attach lamp connector (be sure to align the four connector
pins).
-
Attach the cover with machine screws F .
Main Unit UVC+ Lamp – Blue Base.
PART: TUVL-211P-OS-N9.
Replace after 2 years.
Connecting to Power
IMPORTANT: Before connecting to power confirm which model is being installed. Turn off main power source before installation. Always use proper conduit fittings and terminations. Model information is printed on the Power Unit cover.
IMPORTANT! Must be wired to constant power – do not connect to blower
relay.
STEP 4: Replace the AKTIV8 UV lamp every 2 years.
Note: UV lamps may continue to emit visible light after two years,
however, germicidal effectiveness decreases over time. After two years of
operation the UV lamp should be replaced.
Never expose eyes or skin to direct UV light.
CAUTION!
UV lamps contain small amounts of mercury – dispose of lamps in accordance
with local environmental regulations. For more information visit
www.lamprecycle.org.
Note: Use of replacement UV lamps other than TUVL-211P-OS-N9 (for AKTIV8) voids warranty.
Secondary UV Light Installation Instructions (Dual Systems).
The Secondary UV Light (included with dual air treatment systems) is typically installed at the coil for enhanced germicidal effectiveness, reduced system maintenance, and improved indoor air quality.
J Remote UV Lamp – White Base PART: TUVL-211P Replace after 2 years.
IMPORTANT!
- Dual System lamps are wired in series – connect both for lamps to light
- Only qualified technicians should install this product
- Install in accordance with relevant building codes
- Read instructions carefully including safety warnings
Installation Notes
Before installing the Secondary UV Light it is necessary to determine the optimal mounting location inside the air system. First, look for the area with the heaviest mold growth. Also consider a location that will allow the germicidal UV Light to shine on the greatest surface area.
Some typical mounting locations:
- Across top of coils
- Coil “A” plate
- Return-side duct
J Remote UV Light
WARNING
PROTECT EYES & SKIN FROM UV LIGHT TURN OFF UNIT OR DISCONNECT BEFORE
SERVICING.
Important: Some materials inside the air system (including filter media,
flex duct, wiring etc) may not be UV light resistant.
Use the optional UV shield (part #TUV-SHIELD-LPC) or cover the materials with
reflective tape.
STEP 1: Air Handler Interior Surface Installation
- Determine the optimal position for placement of the UV Lamp.
- Use a utility knife to cut a slit in the insulation on the interior surface.
- Place the magnetic bracket directly on the metal surface or remove the magnet and hard-mount the bracket using the Self-tapping Screws provided. Use foil tape to close the cut in the insulation.
- Use plastic Quick-Nuts to attach the UV lamp to the bracket as shown.
STEP 2: Coil “A” plate or Duct Installation
- Snap the magnet bracket apart by bending.
- Drill a 1” hole in the “A”-plate or duct then attach the smaller piece of the bracket with Self-tapping Screws.
- Insert the UV lamp into the hole then use the plastic Quick-Nuts to attach the UV Lamp to the magnet bracket as shown.
STEP 3: Remote UV Light Configuration
IMPORTANT! Only Dual System models have the electrical capacity and attached cable to power the Secondary UV Light.
Find the secondary lamp cable on the right underside of the Dual System Main Unit.
Drill a 1” hole in the air system housing then pass the lamp cable through the
hole. The hole is then sealed with the rubber grommet to minimize air leakage.
STEP 4: Sight Glass Installation
- Snap the magnet bracket apart by bending.
- Drill a 1” hole in the “A”-plate or duct then attach the smaller piece of the bracket with Self-tapping Screws.
- Insert the UV lamp into the hole then use the plastic Quick-Nuts to attach the UV Lamp to the magnet bracket as shown.
STEP 3: Remote UV Light Configuration
IMPORTANT! Only Dual System models have the electrical capacity and attached cable to power the Secondary UV Light.
Find the secondary lamp cable on the right underside of the Dual System Main Unit.
Drill a 1” hole in the air system housing then pass the lamp cable through the
hole. The hole is then sealed with the rubber grommet to minimize air leakage.
STEP 4: Sight Glass Installation
- Apply the warning/lamp replacement sticker K on or near the HVAC system.
- Drill a ½” hole through the circle on the sticker. Press the sight glass L into hole.
- Turn on the power and use the sight glass to confirm that the UV Lamp is operating.
STEP 5: Replace the secondary UV lamp every 2 years.
Note: UV lamps may continue to emit visible light after two years, however, germicidal decreases over time. After two years of operation the UV lamp should be replaced. Never expose eyes or skin to direct UV light.
J Remote UV Lamp – White Base PART: TUVL-211P Replace after 2 years
CAUTION!
UV lamps contain small amounts of mercury – dispose of lamps in accordance
with local environmental regulations. For more information visit
www.lamprecycle.org.
Note: Use of replacement UV lamps other than TUVL-211P (for secondary UV light) voids warranty.
