Installation
1.
Turn off all power breakers running to AU unit before removal of any
part of the airhandler.
DANGER
There is an electrical shock hazard if the airhandler is powered on
during the installation of this retrofit kit.
2.
If necessary, close ball valves to isolate the AU airhandler and remove
water connections so that the AU can be moved to an accessible
location.
3.
On the top of the AU, remove cover screws and lift out the cover panel.
See Figure 1.
4.
Using the two screws supplied, secure BE bulb bracket to the cover
panel, as shown in Figure 2. Ensure that the BE setup is oriented so
that it does not overhang past the cover panel.
5.
Connect the wiring harness plug to the BE bulb. Route the harness
through the plastic fitting in the cover panel. If the AU is equipped with a
heater, ensure that the wires are routed through the plastic fitting on the
heater bracket also. It is important to keep the wires from touching the
heater coils as it may cause damage. See Figure 3.
WARNING
Do not let the BE's electrical wires contact the heater if one is
installed. Use the heater bracket's plastic fitting to keep the wires
away from the heating coils.
6.
Replace cover panel with screws onto AU.
7.
Route the wiring harness back to the AU electrical box.
8.
Check the ballast to ensure that it is set to the correct voltage for your
installation. The toggle switch can be set for either 120V or 220V. See
Figure 4.
9.
Attach the ballast to the electrical box by placing it on the studs in the
box and secure with two nuts supplied in the location shown in Figure 5.
10. Crimp wiring harness from the BE bulb to the ballast. The blue and
white striped harness wires are attached to the blue ballast wires while
the red and white stripped harness wires are attached to the red ballast
wires.
11. Wire the ballast into the terminal strip, as shown on the wiring diagram
on the lid of the electrical box.
12. Supply power to the electrical box to check functionality of the UV bulb.
The glow of the UV light should be easily seen through the evaporator
coil of the unit. Never look directly at a lit UV bulb! Also, be sure to check
the pilot light on the ballast to ensure it is illuminated. The blue pilot light
will be lit only if power is applied to the unit and the bulb is operational
(i.e., if the bulb is not properly seated but power is connected, the pilot
light will not be lit).
13. Place UV light warning stickers on unit in a clearly visible location.

DANGER
Never look directly at a lit UV bulb.
14. Place the UV bulb date sticker on the unit in a clearly visible location and write
the initial date of startup. The UV bulb lasts approximately 1 year as it operates
continuously and should be replaced annually.
15. Route the 7-inch (178 mm) wire of the blue pilot light to a point where the pilot
light can be seen easily.

PERATION
On
The Breathe Easy unit is in operational ready mode when power is supplied to the unit and the bulb is lit and the blue pilot light on the ballast is lit.
The air purification process begins when the air conditioning system's blowers begin moving air through the tube.
NOTE
It is normal for the Breathe Easy UV bulb to remain lit as long as power is applied to the unit at the breaker, even if the AC unit is in
OFF mode. This maximizes the life of the bulb. One hour of bulb life is lost each time it is turned on and off, which is why the unit
should never be wired to blower power.
Off
Disconnect power to the unit by turning off the breaker to the air conditioning system's incoming terminal strip. Always turn the unit off when
performing maintenance.
T
ROUBLESHOOTING
No power, unit does not turn on (no blue glow).
1.
Verify that the power source is working.
2.
UV bulb is not seated correctly in the socket (see "Replacing the UV Bulb").
3.
UV bulb needs to be replaced (see "Replacing the UV Bulb").
4.
Blue light on the ballast is not lit (see "Replacing the UV Bulb").
5.
Replace ballast if you have a known good bulb and power is on to ballast (confirmed with a volt meter at power terminals).
6.
The unit is configured for 230V/50Hz or 60Hz as a default. If it is to be used for 120V/60Hz the switch on the ballast must be
switched to the left to the 120V/60Hz position.
Output seems ineffective.
1.
Make sure unit is servicing an enclosed area.
2.
Remove any obstructions in the air stream's input and output vents.
3.
Clean the air filter of the air conditioning system.
4.
Is it time for a new bulb? The UV bulb should be replaced each year (see "Replacing the UV Bulb").
5.
Replace bulb if it is gowing red, not blue (see "Replacing the UV Bulb").
