WHOLE HOUSE
The Fresh-Aire UV Purity™ germicidal ultraviolet light and filtration system
offers the ultimate enhancement to indoor air quality. The system features
three unique echnologies (advanced filtration, germicidal UVC light, and
photocatalytic oxidation) that improve indoor air quality by actively reducing
airborne microbial contaminants and odor-causing volatile organic compounds.
The Purity™ unit is installed directly onto the return side of the air handler
or gas furnace.

System Installation
-
Before installing Purity™ remove the media guide rails (to access screw holes). Rails are held in place with plastic rivets.
-
Attach Purity™ housing to the air system cabinet using self-tapping screws as shown.
-
Replace rails using plastic rivets.
Power Supply
-
Remote-mounted power supplies (ER, ST/DT models) are typically mounted in the control box of the air system and are connected to 110-277 VAC (ST/DT) or wired to the 24 VAC transformer there (ER). Use a separate 24 VAC transformer if needed – see the warning.
24 VAC WARNING!
Systems with high 24 VAC loads may require the installation of a separate 24 VAC transformer to power the Purity™ system.
Always use a separate 24 VAC transformer with “communicating” air systems.
Draws 16 VA, may need to do load calculation: Volts under load X Amps under load. -
Internal power supplies (SP/DP models) are located inside the Purity™ housing and are attached to the back of the removable belly plate. Remove the belly plate to replace the power supply.
-
Power cables pass through a knockout hole on the side of the Purity™ housing. If access is limited pass the cables through the alternate knockout located on the other side.
IMPORTANT! Must be wired to constant power – do not connect to blower relay. -
Wiring
Insert Media
Insert media as shown. Be sure to orient the photocatalytic media so that the UV lamp faces the other filter not outward.
Interlock
To turn on the Purity™ system after installation close the access panel (which closes a spring-loaded interlock switch) and rotate the door latches to the closed position. Opening the access panel switches of the power system for system maintenance.
Replacing Media
Replace PCO Media (which includes the UVC light) every 2 years. Although the
UV light will still glow, after 2 years the germicidal effectiveness will fall
off. Replace with part # TUVLM-PRT.
The UV Reactive Filter Media should be changed every six months, however, it
may last up to a full year depending on local conditions. Replace with part #
TUV-RFM4-XXYY.

Optional 2nd Remote UV Light Installation Instructions
The optional Fresh-Aire Remote UV Light works with the Purity™ system for
enhanced disinfection, reduced system maintenance, and improved indoor air
quality.=
IMPORTANT!
- Purity™ Dual lamps are wired in series – both must be connected for lamps to light
- Only qualified technicians should install this product
- Install in accordance with relevant building codes
- Read instructions carefully including safety warnings
Installation Notes
Before installing the Fresh-Aire Remote UV Light it is necessary to determine
the optimal mounting location inside the air system. First, look for the area
with the heaviest mold growth. Also, consider a location that will allow the
germicidal UV light to shine on the greatest surface area.
Optional 2nd UV Light Parts
A UV Lamp 1 Year (TUVL-115P)
B UV Lamp 2 Year (TUVL-215P)
C Sight Glass
D “Z” Mounting Bracket
E Warning Sticker
Note: lamp A or B and parts C and D E are included with Purity™ Dual.
WARNING
PROTECT EYES FROM UV LIGHT TURN OFF THE UNIT OR DISCONNECT BEFORE SERVICING
Air Handler Interior Surface Installation
-
Determine the optimal position for placement of the UV lamp.
-
Use a utility knife to cut a slit in the insulation on the interior surface.
-
Place the magnetic “Z” bracket directly on the metal surface or remove the magnet and hard-mount the bracket using the self-tapping screws provided. Use foil tape to close the cut in the insulation.
-
Use plastic quick-nuts to attach the UV lamp to the “Z” bracket as shown.
-
Coil “A” plate or Duct Installation
1. Snap the “Z” bracket apart by bending.
2. Drill a 1” hole in the “A”-plate or duct then attach the smaller piece of the bracket using the self-tapping screws.
3. Insert the UV lamp into the hole then use the plastic quick-nuts to attach the UV lamp to the “Z” bracket as shown.
-
Remote UV Light Configuration
IMPORTANT! Only the Purity™ Dual model (with the ST Power Supply) has the
electrical capacity for the optional Remote UV Light. The cable for the reomte
lamp passes through the knockout on the left side of the Purity™ Housing. To
add a second UV light to an existing Purity™ system that is not a Dual model
install a separate Fresh-Aire UV AHU Series 1 or Blue-Tube UV system.
-
Remote UV Lamp Connection
1. When all the other components are properly installed connect the UV Lamp cable to the Purity™ power supply cable.
2. Make sure the flanges are aligned and then push the connectors firmly together. A tight connection ensures a proper water-resistant seal.
-
Sight Glass Installation
1. Find a suitable location on the outside of the ductwork near the UV Lamp installation and apply the Fresh-Aire UV® warning/lamp replacement sticker.
2. Drill a ½” hole through the orange circle on the sticker. Press the UV safety viewport into the hole.
3. Turn on the power and use the sight glass to confirm that the UV Lamp is operating. -
Lamp Replacement
The germicidal UV lamp in the Fresh-Aire Remote UV Light needs to be replaced periodically. A TUVL-115P lamp should be replaced every year. The TUVL-215P should be replaced every 2 years. Note: UV lamps will continue to emit visible light but lose germicidal effectiveness over time. You can upgrade to a 2-year lamp with your existing power supply.
CAUTION!
UV lamps contain small amounts of mercury – dispose of lamps in accordance
with local environmental regulations.
