The UV-12C,18C,28C,12HPC,18HPC, and 28HPC units are equipped with a circuit board to monitor the operation of the UV lamp; it indicates the operation of the lamp through an LED indicator light mounted on the cover of the unit. The circuit board indicates good operation of the lamp by a continuous “GREEN” color on the LED light. After 8,320 hours of lamp operation, the circuit board indicates the elapsed time of lamp operation by a continuous “YELLOW” color on the LED light and the internal alarm will beep every 15 minutes. After 9,000 hours of lamp operation, the circuit board indicates the elapsed time of lamp operation by a continuous “RED” color on the LED light and the internal alarm will beep every 5 minutes. The board also checks if the UV lamp is burned out. If the lamp is burned out, the circuit board will indicate this by a continuous “RED” color on the LED and the internal alarm will beep every 5 minutes.
WARNING: Before installing or servicing a humidifier, air filter, heat system, or this unit, etc., always turn all power OFF and have unit unplugged. Electrical shock can cause personal injury or death. Never expose eyes or skin to direct UVC light from any source.
WARNING: To prevent water damage or electric shock, do not mount unit under a humidifier.
WARNING: Designed for a closed duct system. Do not mount near a supply or a return air opening.
WARNING: This product is designed for indoor installation only (i.e. attics, crawl spaces, basements, etc.). For use on gas fired, oil fired, electric and split system heat pump forced air systems*. This product is NOT designed to be mounted outside on gas fired or heat pump packaged units**.

*Split system heat pumps are systems where the air handler and the air conditioning compressor are separate units.
**Packaged units are systems where the air handler and the air conditioning compressor are built together and are installed outside of the building

INSTALLATION

1. Locate a suitable location for the unit downstream from the ‘A’ coil in the supply plenum or in the return plenum; preferably downstream from the air filter. For optimum “cleaning” effect on the ‘A’ coil, mount the unit in the supply plenum as close as possible to the ‘A’ coil. (See Figure 1)
   

2. Determine the type of duct you have.
   (For flex duct applications, refer to Figure 26 on page 11)
   IF YOU HAVE METAL DUCT:
   a. Apply supplied wet and stick mounting template to air duct in either a vertical or horizontal position as shown in Figure 2.
   b. Drill 1/8” diameter mounting holes at positions indicated on template.
   c. Cut out the marked openings on the template. (Refer to template as shown in Figure 2)
   d. Remove the paper template from the duct.
   IF YOU HAVE DUCT BOARD:
   a. Mount the supplied metal mounting plate onto the duct with duct tape in either a vertical or horizontal position (See Figure 2 & 3)
   b. Bend tabs outward as shown in figure 4.
   c. Using a knife or blade, cut out a rectangle opening in the duct using the mounting plate as a template. (See Figure 5)
   d. Remove the cut piece of duct. (See Figure 6)
   e. Bend both tabs down and through duct at first bend point. (See Figures 7&

8. f. Bend both tabs at the second bend point up or down to pinch the duct material and grip the duct material.
   (See Figures 9 & 10)
   g. Using a screwdriver or pointed object, locate mounting holes by poking holes through the duct tape. (See Figure 11)
   

3. Remove base unit and cover from box.

4. Apply supplied “Duct Seal Kit” according to instructions included in kit. (See Figure 12)
   

5. Determine whether to use flat or angled bracket. (Refer to “Bulb Mounting Bracket Selection” in Section VI for aid in this decision)
   a. Flat Bracket Installation
   i. Remove the two hex nuts and flat bracket from included bagged hardware.
   ii. Install the flat bracket and secure to the unit base with the hex nuts provided. (See Figure 13)
   b. Angled Bracket Installation
   NOTE: For angled bracket mounting, refer to specifications outlined by Charts A & B for mounting distances in the “Angled Lamp Mounting Bracket Specifications” in section VI.
   i. Remove the two hex nuts and angled bracket from included bagged hardware.
   ii. Install the angled bracket and secure to the unit base with the hex nuts provided. (See Figure 14)
   NOTE: Be sure to note location of lamp hole in bracket relative to unit base.

6. Mount the unit base to the duct using the four mounting screws provided. (See Figure 15)

7. Remove tag and alcohol wipe from lamp. Wipe off lamp being sure not to touch lamp with bare hands. The oils in your hands cause a reduction in lamp output.
   

8. Insert lamp through the hole until lamp cannot be inserted any further. (See Figure 16)

9. Swing the swivel bracket over the end of lamp. Hand-tighten the wing nut on the stud. Be careful no to over tighten the wing nut. The porcelain at the lamp base may crack when over tightened. (See Figure 17)
   

10. Plug ballast plug into end of lamp. (See Figure 18)
    

11. Snap cover onto the unit base. (See Figure 19)

12. Plug the LED wire from the cover onto the board. (See Figure 20)
    

13. Close the cover and tighten cover screw. (See Figure 21)
    

14. Plug the power cord into a standard electrical outlet.
    NOTE: Seal the joints and seams of the plenum near the mounting location to reduce any direct viewing of light. (See Figure 1)

15. Press the power switch to the “ON” position. (Light on switch should be on indicating power.)

16. Look through view port in the box cover to be sure the lamp is working. You should see a blue glow. (The view port is covered with a plastic lens that blocks the UVC rays.) If equipped, the LED light will show a continuous “GREEN” color indicating proper unit operation.

17. If the lamp is not glowing, follow steps 8-14 again. If lamp still does not glow, contact technical support at 1-252-522-3031 for further assistance.

INCORPORATING A THERMOSTAT

(Be sure to follow any applicable state or local codes)
The UV Aire units supplied with a circuit board allows for the automatic operation of the UV lamp when the there is a call for heating or cooling by the thermostat. After the call for heat has been satisfied, the UV Aire unit will operate for 45 minutes then shut off.

1. Turn off power switch on the UV Aire unit and unplug the unit before doing any wiring.
2. Loosen the cover screw and open the unit cover.
3. Locate terminals 1-2 on the circuit board and remove the jumper wire.
4. Wire to terminals W, C and G into the fan center on the furnace. Refer to Diagram A for proper wiring.
5. Close the cover and secure with the cover screw. Then plug the UV Aire back into the power receptacle and switch the power switch to the “ON” position

SYSTEM CHECK OUT PROCEDURE:

1. With the thermostat set to the heating mode, adjust the thermostat for a call for heat. The furnace and the UV Aire should start operating. Turn down the thermostat to stop the call for heat. After 45 minutes, the UV Aire lamp will turn off.
2. With the thermostat set to the cooling mode, adjust the thermostat for a call for cooling. The furnace and the UV Aire should start operating. Turn up the thermostat to stop the call for cooling. After 45 minutes, the UV Aire lamp will turn off.
   

ALARM CIRCUIT WIRING

The UV Aire units supplied with a circuit board allows for the wiring of the UV Aire unit into an alarm or security system to monitor the operation of the UV lamp. This circuit is a set of normal open contacts that close if the operational time exceeds 9000 hrs or if the lamp burns out.

1. Turn off power switch on the UV Aire unit and unplug the unit before doing any wiring.
2. Loosen the cover screw and open the unit cover.
3. Locate terminals 1-2 on the circuit board and remove the jumper wire.
4. Wire to terminals A1-A2 and wire in accordance with Diagram B.

SYSTEM CHECK OUT PROCEDURE

1. Plug the UV Aire back into the power receptacle and leave the power switch in the “OFF” position.
2. Unplug the Ballast connector from the lamp and switch the power switch to the ON position. The unit will start and operate for approximately 10 seconds. Then the LED will  witch to a RED color and the alarm contact will close.
3. Switch the power switch to the OFF position and reconnect the ballast connection to the lamp. Close the cover, secure with the cover screw, and switch the power switch to the  ON position.
