Unpacking the ComAir 20T unit.
1. Carefully remove the parts from the package. The lamps are fragile and proper care must be taken
when removing packaging that is placed around them.
2. Do not touch the lamps with your bare hands, as oils from your hands can create “hot spots” which
reduce the lamp life. In case of contact with the lamp, wipe the lamp clean with a soft cloth dampened
with rubbing alcohol.
3. Check the parts list below to make sure you have all of them:
• One ComAir 20T Main unit
Ozone Lamp
Germicidal Lamp
Lamp Shield
Air Flow PCB
• Four self-tapping screws
• Installation/owners manual
• Warranty card
COMAIR 20T INSTALLATION
Assembly:
1. Remove the four screws from the cover of the unit and remove the cover.
2. See figures on page 11 and 13 for locations of components. Install lamp shield by using the hardware
that is attached to the main unit. Attach shield to main unit and tighten the two nuts.
3. Install Ozone Lamp: Loosen the lamp lock nut from the lamp holder by turning it counterclockwise and
remove.
4. Remove the metal washer and the rubber bushing from the lamp holder and install the rubber
bushing on the lamp.
5. Slide the lamp into the lamp opening. Handle lamp by the end cap.
6. Re-install the metal washer and lamp lock nut. Carefully tighten the lamp lock nut.
7. Connect the lamp connector to the end of the lamp.
8. Install Germicidal Lamp: Remove nuts and washers from the mounting studs.
9. Check to be sure that the O-ring is installed around the base of the lamp. Insert lamp into the main
unit. The two mounting ears on the lamp base should go through the mounting studs.
10. Install the plastic washers and nuts. Tighten nuts snugly, but do not over tighten.
11. Connect the lamp connector.
12. Insert the Air Flow PC Board into the hole on the bottom of the unit. The sensor connector is keyed
so it can only go in one way.
