Installation Guide for VEVOR 2402-UV18 and 2402-UV25 HVAC Air Purifier

Quick Guide from the Manual

This document provides installation and maintenance instructions for the VEVOR 2402-UV18 and 2402-UV25 HVAC Air Purifiers. These units are designed to be installed within HVAC ductwork to improve air quality. Important: UV light is harmful to skin and eyes; never look directly at the light. Installation should be performed by an adult, and the unit must not be installed where people can see the UV light.

Safety Instructions

• UV Hazard: UV light causes temporary or permanent blindness. Never look directly at the light.
• Installation Safety: Disconnect power before installing or replacing the bulb. Wear gloves to avoid cuts.
• Environment: Do not install in wet environments, humidifiers, kitchens (oily fumes), or areas with acidic/alkaline/organic gases.
• Handling: The lamp contains mercury; handle with care. Do not clean broken lamps with a vacuum cleaner.
• Modification: Do not modify the unit.

Kit Parts

• UV Unit
• Magnetic bracket
• UV tube
• ST4*25 screws (4pcs)
• M5*12 bolts (2pcs)
• M5 nuts (2pcs)

Installation Instructions

Selecting Mounting Location: Install on a flat surface of the ductwork, preferably above the air conditioning cooling coil (A-coil). If no A-coil exists, install on the supply air duct. Ensure the unit is away from plastic or rubber components that could be damaged by UV light; use aluminum foil duct tape to protect such components if necessary.

Installation Steps:

1. Pass the power cord through the circular hole of the magnetic bracket and connect the coupler to the lamp base.
2. Attach the lamp tube to the magnetic holder using the two M5 bolts and nuts.
3. Fixing the unit: The unit can be held by the magnet against the inner wall of the pipe, or secured using screws.
4. If installing from the outside, cut an installation hole, align the magnetic support with drilled 3mm screw holes, and fix with screws.
5. Seal any excess incision with aluminum foil tape or insulation material to prevent UV light leakage.
6. Secure the ballast to the pipe wall using two ST4*25 screws.
7. Reconnect power to the HVAC system.

Bulb Cleaning and Replacement

1. Disconnect power and allow the bulb to cool for at least 15 minutes.
2. Remove the 2 support screws and slide the unit out.
3. To Clean: Wipe the bulb with a soft cloth dampened with glass cleaner. Ensure it is clean and dry before re-installation.
4. To Replace: Press the bulb release button to remove the old bulb. Slide the new bulb in until it snaps into place.
