DIY steps
- Identify the device type before installation. A portable plug-in purifier needs no building-wiring work; an HVAC UV unit must be installed only as its manufacturer specifies, with its circuit de-energized and no exposed UV lamp.
- For a portable unit, choose the clearance and mounting method specified by its manufacturer and fasten any wall bracket to suitable framing or rated anchors. For an HVAC UV unit, use only the manufacturer-specified duct location and mounting method.
- Do not use wire nuts on a portable plug-in purifier. For an HVAC UV unit, make electrical connections only as specified by the manufacturer and local code, using approved enclosures; use qualified electrical help if required.
- Plug a portable unit directly into its listed outlet and test it. For an HVAC UV unit, reassemble all access panels before restoring power and never operate the lamp where UV light can be seen.
- Use a level to ensure the air purifier is installed straight and adjust the mounting bracket as needed. Tighten all screws and wire nuts to secure the installation.
- Clean up any debris or packaging materials from the installation and dispose of them properly. Check the air purifier's filter and replace it as needed according to the manufacturer's instructions.
Common DIY mistakes
-
high Incorrect Wiring
Failing to match the black (hot) wires to the black wires and the white (neutral) wires to the white wires can cause a short circuit or electrical shock.
-
medium Insufficient Mounting

-
medium Ignoring Manufacturer's Instructions
Failing to follow the manufacturer's instructions for installation and maintenance can void the warranty or cause the air purifier to malfunction.
