• Both lamps operate from the same multivoltage ballast.
If the LED does not light:
1. Check to be sure there is power to the unit.
2. Be sure lamp connectors are fastened securely.
3. If the LED still does not light, replace lamp(s).
4. If still not operating, replace ballast.

ACKING THE UNIT
UNP
Each GeneralAire GUV2000 Air Purifier unit is shipped with the
germicidal lamps placed in tubes with protective packaging. Carefully
remove each lamp from the tube taking care to not touch the glass
portion of the lamp 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 removing from packaging.
Be sure all parts are included in the following list:
• GeneralAire GUV2000 Air Purifier
• Two 16” GermicidalLamps (packed in tube)
• Four Sheet Metal Screws and two keps nuts
• Titanium Photocatalytic Reflector
• Installation & maintenance instructions
IMPORTANT SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions
should always be followed including the following:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. SAVE THESE INSTRUCTIONS.
Always be sure the unit is unplugged during installation or service procedures.
3.
4. The ultraviolet light produced by the UV lamps is harmful to your eyes.
Do not look directly at the lamps. Should it become necessary to view the
lamps, use UV-protected safety goggles.

INSTALLATION
• Best results are achieved when the unit is installed where the HVAC system air temperature is most constant.
Therefore, the preferred installation is on the return sideof 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 directly exposed to the UVlight, such as
a return side humidifier or certain types of air filters. Check with the filter manufacturer to see if their material is
UVresistant. Over time, UVlight will degrade many plastic materials.
• Do not touch the glass portion of the lamps 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. Cut out the opening indicated by a dotted line on the installation template.(See insert)
2. Center template on the longitudinal axis of the plenum using tape to hold it in place.
Trace the hole pattern for the unit and
mark centers for mounting screws.
(Photo A)
3. Cut opening for the unit and drill 9/64” holes for
sheet metal screws.
4. Remove the cover from the unit using an 11/32
size nut driver to remove the top and bottom
retaining nuts and set aside.
8-32 keps nuts
5. Attatch the titanium reactor panel to back of
unit as an inverted “V” to maximize airflow
(as indicated in photo A.) Use an 11/32 size nut
driver and the 8-32 keps nuts packaged with sheet
metal screws and fasten securely
6. Attach unit to air duct using the four
sheet metal screws provided.
7. Remove germicidal lamp holder (Figure A)
using a 11/32 size nut driver.
8. Slide germicidal lamp into lamp opening.
9. Reinstall lamp holder.
10. Plug in lamp connector to the end of lamp.
11. Repeat steps 6 thru 9 for second lamp.
12. Replace the cover and secure using
the two retaining nuts.

WIRING
Simply plug the unit into an 120 VAC outlet and allow it to run continuously.
The multivoltage ballast is
self-adjusting and operates with voltages from 115 VAC through 277 VAC. For connecting to voltages higher than 120 volts AC remove plug and wire in accordance with local wiring codes.
MAINTENANCE
This maintenance schedule is only a guideline, determined by average conditions. Actual
conditions will dictate the frequency of cleaning and/or replacement of lamps. Do not touch
the glass portion of the lamps 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.
CLEANING THE LAMPS REPLACING THE LAMPS -
1. Unplug the power cord from the outlet, or disconnect power to the unit.
2. Remove the cover from the unit using a 11/32 size nut driver to
remove the top and bottom retaining nuts .
3. Unplug the lamp connector from the end of each lamp.
4. Remove lamp holders using a 11/32 size nut driver. (Figure A)
5. Remove each lamp by grasping the porcelain cap and
extract carefully.
6. Using a soft cloth moistened with rubbing alcohol, wipe down
each lamp. If there is a large build-up of dust particles, you may
want to use a can of air first. Always handle lamps by end caps.
7. Slide one lamp back into lamp opening. Reinstall lamp holder.
8. Repeat step 7 for second lamp.
9. Plug the lamp connector to the end of each lamp.
10. Replace and secure cover using the two retaining nuts.
Recommended interval: 12 months
Recommended interval: 24 months. (Follow procedure below excluding #6.)
(Follow procedure below)
11. Plug power cord back into outlet, or restore power to unit.
