1Read instruction manual before operating the units.
2Eye damage may result from directly viewing the light produced by these lamps. To reduce the risk of expo-
sure to UV radiation, take UV-radiation protective measures for personnel during servicing.
3This fixture is designed for use with germicidal UV-C lamps and must be installed in compliance with com-
petent technical directions so that user’s eyes and bare skin will not be subjected to injurious rays.
4UV Light Hazard. To prevent exposure to ultraviolet light, be sure the ultraviolet air treatment system is dis-
connected before servicing any part of the HVAC system or removing any access panel or the equivalent.
5There shall not be any openings in the duct that would emit light.
6There shall not be any duct supply or return air openings or any other openings that are in direct line-of-sight
of the UV bulb.
7Check damaged parts: Before further use of the unit, any damaged part should be carefully checked to ensure
that the unit will operate properly. Any part that is damaged should be properly repaired or replaced.
CAUTION:
1Personal Injury Hazard. Power supply can cause electrical shock. Disconnect power supply before servicing
or beginning installation.
2Risk of exposure to excessive ultraviolet (UV) radiation—Do not operate without complete lamp enclosure in
place or if sight lens is damaged.
3Equipment Damage Hazard. Ultraviolet light can cause color shift or surface degradation and sometimes
structural degradation of non-metallic components. Select mounting location that prevents exposure to plas-
tic flexible duct components, polyurethane foam insulation material, rubber hoses, wire insulations, etc. If
mounting options are limited, items above should be protected with ultraviolet resistant materials such as
aluminum foil, aluminum duct tape, or metallic shields.
WARNING: FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY
INSTALLATION LOCATION:
1. See page 4 for possible installation locations.
2. Products shall be mounted only on to metal air ducts.
3. Mounting shall be such that all surfaces in the duct where appliance forms parts of the duct shall be made of
metal.
4. All wiring within adjacent heating and air conditioning equipment, for example, shall be shaded from direct
line-of-sight from the UV bulb or shall be UV-rated.
Please read all instructions carefully to help ensure a correct and SAFE installation of your Second Wind™
Ultraviolet Air Purifier. Failure to do so could damage the equipment or cause harm to yourself or others. Only
qualified Heating Ventilation and Air Conditioning (HVAC) technicians should perform the installation.

Units
FIG.1
1. Install the lamps where you have easy access.
2. Before drilling into equipment, make sure that there is nothing in the way that would be damaged.
3. The lamp should be installed a minimum of 2-3 inches, maximum 39 inches, away from the coil or pan sur-
face when installation for coil cleaning.
4. Use one or more units to treat the coil surface area, as shown in Fig.1 and Fig.2. Areas shaded from direct
exposure to the lamps will not be disinfected. The greater the amount of coil and drain pan area exposed to
the lamp, the greater the amount of biological reduction.

• The installation should be done by a qualified HVAC contractor. Unit must be installed in compliance with all
national and local electrical and mechanical codes. Failure to do so will void ETL safety listing and Second
Wind warranty.
• Read all safety instructions at the beginning of this manual. Failure to do so could lead to personal injury and/
or equipment damage.
• In cases where molds are already present on the evaporator coil, it is recommended that a qualified HVAC
technician clean the coil before the installation of the UV lamp.
• Safety interlock switches for the access panel are recommended but not supplied.
• Make sure the rooftop unit power has been shut off at the main power source before
installation.
• Protect all non-UV resistant materials from direct UV exposure with aluminum tape
or metal conduit.
• CAUTION: Ultraviolet light can be harmful to your sight, do not look at the lamp
when it is illuminated.
1. Using the Second Wind NEMA unit as a template, mark the (4) mounting holes on the surface where the device
is to be installed.
2. Open the enclosure wit flat screwdriver.
3. Mark the Ø7/8 conduit hole location for the electrical supply.
4. For 3000 Series units, mark the position of the smallest diameter on keyhole lamp plate (Fig. 1).
5. For 2000-230OD, and trace perimeter of rectangle cutout on enclosure.
6. Cut electrical access hole and lamp access hole or cutout, depending on model, remove all metal and clean
rough edges to prevent damage to unit.
7. Secure NEMA encloser in position and secure with appropriate hardware (not included).
8. Ensure that NEMA enclosure fits flush against the equipment or duct to ensure gasket seal of joint. Seal
perimeter of enclosure with outdoor silicone.
9. Remove lamp(s) from tubes inside carton, use an alcohol wipe to remove any dirt or fingerprints from the lamp
if present.
10. 3000 Series—insert the lamp into the larger diameter of keyhole, and lower into the smaller diameter. Ensure
that the lamp is secured in lower diameter.
11. 2000-230OD only—perform same as #10 on lamp bracket assembly, then secure opposite end of lamps in
spring clamps at end of assembly. Install in NEMA enclosure and secure with locknuts.
12. Attach the lamp connector to the lamp. There is only one way to attach the connector to the lamp. If it does
not go on, rotate the connector 90 degrees and try again.
13. With the cover of the NEMA enclosure still open, access the ballast and wiring. Install the proper
weatherproof conduit on the bottom of the enclosure. Connect the electrical service through the conduit.
Connect the black and white wires to power and the green wire to ground. Install access panel disconnect
switch, NOT INCLUDED. Refer to the wiring diagram (Fig. 3).

The Second Wind Ultraviolet Germicidal Lamp is designed for 9000-11,000 hours of continuous operation. After
9000 hours, intensity of the lamp inside the duct diminishes and should be replaced. Even if the lamp is still
illuminated, replacement of the lamp is recommended, by a qualified HVAC Service Technician.
1. Disconnect electrical service
2. Open NEMA enclosure cover.
3. Disconnect the lamp connector from the lamp base.
4. 2000-230OD only - remove locknuts from lamp bracket assembly, remove lamp from spring clamps at end of
lamp.
5. All Models - Remove old lamp(s) CAUTION: old lamp may still be hot to touch.
6. Replace the old lamp with the new lamp, ensuring the lamp is clean. If dirty, remove w/alcohol wipe.
7. 2000-230OD only – secure lamp bracket assembly with locknuts.
8. Attach lamp connector(s) to lamp base(s).
9. Close the NEMA enclosure cover and screw tight to make sure the interlock switch is activated.
10. Turn on electrical service.
UV lamps contain mercury like other household lamps and must be disposed of properly. State requirements and
recycling opportunities vary, go to www.lamprecycle.com for State Regulations & Contacts. Please contact
your county waste collection department for proper disposal details.
USE GLOVES AND EYE PROTECTION
If a lamp is broken, do not use a vacuum cleaner to pick up the waste or burn the lamps. Instead, sweep up the
waste into a plastic bag and seal. Contact your county waste collection department for proper disposal details.
Troubleshooting
Lamp Disposal
Lamp Replacement
If the unit does not work, check the following:
Electrical Supply/Wiring—Verify that the electrical service is operating correctly
Fuse—If the lamp is still not illuminated, turn off electrical supply and dcheck the fuse. Look to see if FUSE is
blown; or check fuse continuity with multi-meter. Replace with part #102-409 (GFI #4971).
Ballast—If lamp still is not illuminating, check the wiring to the ballast. If the ballast is wired properly and the
lamp still does not illuminate, replace the ballast. With a fully electronic ballast there is no resistance testing.
Lamp—Verify that the lamp is not broken and is properly seated in the lamp connector. To check this, follow
septs in the ‘Lamp Replacement” section with one exception: you should not remove and replace the lamp. If the
lamp is broken, read the “Lamp Disposal’ section of this manual.
