Before installing the Scorpion LX15, it is necessary to determine the optimal mounting location inside the air system. Consider an installation location that will allow the Scorpion UVC LED light to shine on the greatest surface area of the coil. For enhanced antimicrobial effect, multiple Scorpion UVC LED lights can be installed in the system. Below are various placement options for the Scorpion LED.

MOUNTING DIRECTIONS

OPTION 1: Scorpion installed inside the coil using the integrated magnet

• STEP 1: Confirm power is off to the system. Remove the access panel to the air handler.
• STEP 2: Remove the “A” panel on the evaporator coil to gain access to the center of the coil.
• STEP 3: Using the Scorpion’s integrated magnet, attach the Scorpion to the metal “A” panel on the far side of the evaporator coil.
  • For a “W” or “N” shaped coil, install a second Scorpion inside the second section of coil. See example image in Figure 1.4.
• STEP 4: Run the wires down the cabinet, cut a small access hole for the wires if one does not exist.
• STEP 5: Replace the “A” panel on the evaporator coil that was previously removed.

OPTION 2: Scorpion installed inside the coil using the provided hardware

• STEP 1: Confirm power is off to the system. Remove the access panel to the air handler.
• STEP 2: Drill a 1 ¼” hole in the “A” plate of the evaporator.
• STEP 3: Insert the supplied grommet into the hole drilled into the “A” plate.
• STEP 3: Insert the LED bulb in the grommet which is placed inside of the drilled 1 ¼” opening.
• STEP 4: Secure the Scorpion to the “A” plate using the provided hardware.

For a “W” or “N” shaped coil, install a second Scorpion inside the second section of coil after drilling the 1 ¼” hole in the second panel, inserting the grommet, and securing the Scorpion. See example image in Figure 1.4.

OPTION 3: Scorpion installed above the coil

• STEP 1: Confirm power is off to the system. Remove the access panel to the air handler.
• STEP 2: Using either the integrated magnet or supplied hardware, secure the Scorpion to the side wall of the unit above the coil. See figure 1.2 for example.

WIRING DIRECTIONS

• STEP 1: Connect the Scorpion to 24VAC power using the white (neutral) and black (hot) wires. The Scorpion can be wired directly to the HVAC systems 24VAC transformer, or add a 24VAC transformer as needed. The Scorpion LX15 can be wired to 18-32VAC input and connected to the door interlock switch so the Scorpion powers down if the door/access panel is open. See figure 1.5 below for wiring diagram. Wire the Scorpion to continuous power, do not connect to the blower relay. See Step 2 for option modes to cycle the Scorpion with the fan.
• STEP 2: Set the Scorpion power switch to “ON” for constant run mode. Set the power switch to “CYCLE” to run only when the fan is running and The integrated air flow sensor activates the Scorpion to power on. (The cycle mode is recommended for longer service life for most applications.)
• STEP 3: Replace the access panel to the unit.
• STEP 4: Place the provided WARNING/INSTALL DATE sticker on the exterior of the unit.
• STEP 5: Add the date of installation using permanent marker on the sticker.
• STEP 6: Restore power to the unit.
• STEP 7: Register the Scorpion’s warranty at www.nucalgon.com.scorpionregistration

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.
• Some materials inside the air system (including filter media, flex duct, wiring etc.) may not be UV light resistant.
• Use reflective tape to cover these components.
