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 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 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.

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.

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)

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 volt-

ages 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.
