*Parts included with
your kit will vary depending on the model.
STEP 1: Lamp, Cable & Mounting Magnet Assembly
- Pass lamp base through hole in magnetic mounting bracket.
- Align keys on the lamp and cable, press firmly together.
- Fasten the lamp base to the magnetic mounting bracket using quick nuts.
STEP 1 A: Cable Routing & Power Supply
- Determine the best location for the power supply close to the air system’s electrical components.
- Route the lamp cable through the air system to the power supply.
- Connect the lamp cable to the power supply by aligning the square connectors, then press firmly together until latch catches.
STEP 1B: Coil A-Plate or Duct Mounting
- For A-plate and duct mounting start by snapping the magnetic mounting bracket apart by bending.
- Drill a 1” hole in the A-plate or duct then attach the smaller piece of the bracket using the self-tapping screws.
- Insert the UV lamp into the hole then use the plastic quick-nuts to attach the UV lamp to the magnetic mounting bracket as shown.
STEP 2: UV Lamp Installation
Surface Mount
- 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 mounting 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.
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 #TUVSHIELD-LPC) or cover the materials with reflective tape.
STEP 3: Power Supply & Electrical
IMPORTANT! Check which power supply is included with your Blue-Tube UV-X before connecting to power. Turn off the main power source before installation.
- Find a suitable location for the power supply inside the control panel of the air handler. Install using the self-tapping screws.
- Use the wiring diagrams to connect to power.
The low-voltage power supply connects to the air system’s 24 VAC transformer
(or add a 24 VAC transformer as needed).
Line-voltage power supplies connect directly to 120-277 VAC power.
“ER” Power Supply LED functions
LEDs are visible through the translucent Power Supply housing.
- Confirm LED Switch is in left position to enable LED indicators.
- Blue LED indicates normal operation.
- Red LED indicates lamp fault
- No LEDs indicates no power.
IMPORTANT! Must be wired to constant power – do not connect to blower relay.
STEP 3: Power Supply & Electrical Cont.
IMPORTANT!
Systems with high 24 VAC loads may require the installation of a separate 24
VAC transformer to power the UV light.
Always use a separate 24 VAC transformer with “communicating” air systems.
Draws 20 VA, may need to do load calculation: Volts under load X Amps under
load.
STEP 4 : UV Warning Sticker & Safety Sight Glass
-
Find a suitable location on the outside of the duct-work near the UV Lamp installation and apply the Fresh-Aire UV® warning/lamp replacement sticker
-
Drill a ½” hole through the circle on the sticker.
Press the Sight Glass I into hole. -
Turn on the power and use the sight glass to confirm that the
UV Lamp is operating.
Lamp Replacement
Germicidal UV lamps need to be replaced periodically. Systems will include
one-year, two-year, or three-year UVC lamp(s).
Note: UV lamps will continue to emit visible light but they lose
germicidal effectiveness over time.
CAUTION!
UV lamps contain small amounts of mercury
Note: Use of replacement UV lamps other than Fresh-Aire UV® voids
warranty.
Dispose of lamps in accordance with local environmental regulations.
