ACKING THE UNIT
Each GeneralAire GUV-2018 Air Purifier unit is shipped with
the germicidal lamp p laced i n a tube with p rotective
packaging. Carefully remove lamp from the t ube taking
care to not touch the glass portion with bare hands. Oils
from the hands can cause “hot spots” which reduce lamp life.
Handle by the porcelain caps or use a soft cloth. If you
accidentally touch a lamp, wipe it off using a soft cloth
dampened with rubbing alcohol. The lamp is fragile and
proper care must be taken when it is removed from packaging.
Be sure the following parts are included:
• GUV-161 Air Purifier
• 16” GermicidalLamp (packed in tube)
• Four Sheet Metal Screws and two keps nuts
• Titanium photocatalytic reflector

INSTALLATION
• Best results are achieved when the unit is installed where the HVAC
air temperature is most constant. Therefore, the preferred installation
return side of the furnace. If return side installation is not possible, install
the unit on the supply side, keeping it as far from the heat/cooling source as
possible, and in the main airstream.
• Do not locate the unit within 20” of any plastic material that will be
exposed to the UV light, such as a return side humidifier or certain
filters. Check with the filter manufacturer to see if their material is UVresistant.
Over time, UV light will degrade many plastic materials.
• Do not touch the glass portion of the lamp with bare hands because oils from
the hands can cause “hot spots” which reduce lamp life. Handle either by the
porcelain caps or use a soft cloth. If you accidentally touch a lamp, wipe it off,
using a soft cloth dampened with rubbing alcohol.
1. The ballast is factory set at 120 VAC. For installations that require
240 VAC locate the 120/240 volt power selector on the ballast and
set for the correct voltage. (Photo A)
2. Cut out the shaded area of the installation template.
