ORKS
The In-Duct Dometic Breathe Easy Air Purifier uses your marine air
conditioning system’s blower to move air through the unit where
ultraviolet (UV) light and innovative Photocatalytic Nano-Mesh
technology improve air quality.
The unit uses a specific frequency of UV light that enables maximum
effectiveness in reducing pollutants such as pollen, mold spores,
bacteria, viruses, fumes, and odors, yet it produces no harmful ozone.
UV energy activates the titanium-dioxide catalyst on the surface of the
nano-mesh structure. The molecules of pollutants that come in contact
with the catalyst are reconfigured into nontoxic elements.
The density and quantity of pollutants present affect how rapidly the air will be cleaned. As air re-circulates and makes multiple passes through the
system you will notice continuously improving purification levels.
NOTE: The air purifier does not fix the
source
of ongoing odor problems. For example, a leak that caused mold must be repaired and the mold
must be removed.

Selecting the Location
•
This unit is designed for installation within the supply-air ducting of an air conditioning system positioned downstream of the blower.
•
If there is a T-box or other diverter box attached to the blower, position the unit in line with the side that gets the most air. Or, relocate the
diverter box away from the blower and place the Breathe Easy between the blower and the diverter. If the unit is installed downstream of
a diverter box, be sure the diameter of the Breathe Easy matches the diameter of the outgoing duct. (For example, a diverter box could
have 6” ducting going in, then have 2”, 4”, and 5” branches going out, so you would need a 5”-diameter unit instead of a 6”-diameter unit
to place it on the outgoing branch that gets the most air.)
•
Make sure the ducting that connects to the air purifier is UV-stable. If you can not confirm that it is, replace the ducting in the area
stretching at least 3 feet (1m) before and 3 feet (1m) after the unit with UV-stable ducting to prevent eventual deterioration of the ducting.
Deteriorated ducting may create air leaks that could cause secondary condensation.
•
The ducting should service an indoor area.
•
The unit requires annual replacement of the UV bulb, so situate the unit for easy access to both the bulb housing and the bulb ballast.
•
The unit requires electricity and operates on 115V/60Hz, 220V/50Hz, or 230V/60Hz AC power. Its power supply is auto-sensing, so no
rewiring of ballast or switching is needed to match operating voltage and Hz. See “Power” for electrical specifications.
•
Do not install in areas that may be exposed to flammable gas.
WARNING
•
Do not use outdoors.
•
Keep the cord away from heated surfaces.
•
Never open the cover without turning off the main breaker.
•
Never operate this unit if it has a damaged cord or plug.
•
Never operate this unit if it has been damaged or submerged in water.
•
Do not place in an area where uncured siliconized sealers are being used, as the vapors will inhibit the unit’s photocatalytic
capability.
DANGER
•
Never look directly at a lit ultraviolet (UV) bulb. The direct power of the UV bulb can be harmful to the eyes. However,
looking at the indirect blue glow from the bulb is safe.
•
This equipment is not ignition protected per CFR 183.410 and may not be installed in areas that may be exposed to
flammable gas.

LEANING
Nano-Mesh Structure
Normally the nano-mesh structure of the Breathe Easy Air Purifier is self cleaning and needs no maintenance. In rare instances, however, if debris
accumulates and air purification decreases you may need to clean it.
Make sure power is disconnected before opening the tube.
(See
“Replacing the UV Bulb” for opening and closing instructions.) Blow away debris with canned air suitable for use on computers.
UV Bulb
Air purification effectiveness will decrease if the UV bulb is dirty, and under extreme conditions you may need to clean it.
Make sure power is
disconnected before opening the tube.
(See “Replacing the UV Bulb” for opening and closing instructions.) Gently clean the bulb using rubbing
alcohol on a soft cloth.
T
ROUBLESHOOTING
No power, unit does not turn on (no blue glow).
1.
Make sure the unit is wired to the breaker of the air conditioning system’s incoming terminal strip and the breaker is on.
2.
Verify that the power source is working.
3.
UV bulb is not seated correctly in the socket (see “Replacing the UV Bulb”).
4.
UV bulb needs to be replaced (see “Replacing the UV Bulb”).
5.
Blue light on the ballast is not lit (see “Replacing the UV Bulb”).
6.
Replace ballast if you have a known good bulb and power is on to ballast (confirmed with a volt meter at power terminals).
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”).
6.
Clean the Nano-Mesh structure (see “Cleaning”).
7.
Clean the UV bulb (see “Cleaning”).
