STEP 4 : UV Warning Sticker & Safety Sight Glass
1. 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
2. Drill a ½” hole through the circle on the sticker.
Press the Sight Glass
I
into hole.
3. 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.
Note: Use of replacement UV lamps other than Fresh-Aire UV® voids warranty.

STEP 3: Power Supply & Electrical
IMPORTANT!
Check which power supply is
included with your Blue-Tube UV-X before
connecting to power. Turn off main power source
before installation.
1. Find a suitable location for the power supply
inside the control panel of the air handler.
Install using the self-tapping screws.
2. 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.

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.
CAUTION!
UV lamps contain small amounts of mercury
Dispose of lamps in accordance with local environmental regulations.

PART: TUVL-315 LIFE: 3 Year
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.
Typical UV lamp locations
Surface Mount
1. Determine the optimal position for placement of the UV lamp.
2. Use a utility knife to cut a slit in the insulation on the interior surface.
3. 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.
“ER” Power Supply LED functions
LEDs are visible through the translucent Power Supply housing.
1. Confirm LED Switch is in left position to enable LED indicators.
2. Blue LED indicates normal operation.
3. Red LED indicates lamp fault
4. No LEDs indicates no power.
