Breathe EasyTM Air Purifier Retrofit Kit

For Gold Series (AU) Airhandler

Installation Manual

H I WOW T ORKS

The Dometic Breathe Easy Air Purifier uses your Gold Series (AU) airhandler to move air through the unit where ultraviolet (UV) light and

innovative Photocatalytic Nano-Mesh technology improve air quality.

The purifier uses a specific frequency of UV light that enables maximum effectiveness in reducing pollutants such as pollen, mold spores,

bacteria, viruses, fumes, and odors, while producing 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 of ongoing odor problems. For example, a leak causing mold must be repaired and the mold must source

be removed.

Location

• This Breathe Easy (BE) retrofit kit is designed only for installation within a Dometic Gold Series (AU) airhandler.

• Make sure the ducting that connects to the airhandler 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 unit requires annual replacement of the UV bulb, so situate the airhandler for easy access to the air purifier.

• The unit requires electricity and operates on 120V or 230V AC power.

• The ducting should service an indoor area.

• Do not install in areas that may be exposed to flammable gas.

Power

The unit operates on 120V/60Hz or 230V/50Hz or 60Hz AC power and is wired to the incoming power of the air conditioning system. The unit is

configured for 230V/50Hz or 60Hz as a sed for 120V/60Hz the switch on the ballast must be switched todefault. If it is to be u the left to the 120V/

60Hz position. See Figure 6.

See table on next page for electrical specifications and Figure 6 for wiring information. Do NOT wire the unit to blower power, as this will

significantly reduce the life of the UV bulb and cause damage to the ballast. For the most accurate wiring information, always refer to the

wiring diagram on the inside of the electrical box.

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.

WARNING

An air leak at the duct connection could cause secondary condensation to form, resulting in drips & wetness in the surrounding area.

REPLACING THE UV BULB

Like all light bulbs, UV bulbs have a limited life span. Unlike regular light bulbs that work until they burn out, UV bulbs lose their germicidal

effectiveness over time and must be replaced even though they may still produce light.

After approximately 1 year of continuous use (about 9,000 hours), the UV bulb will lose power and have to be replaced. Replace with a new

Dometic UV bulb. Use of any other bulb will void the warranty.

Refer to Figure 7 below and follow these steps to replace the bulb:

1. Turn off all power breakers running to AU unit before removal of any part of the airhandler.

2. If necessary, close ball valves to isolate the AU airhandler and remove water connections so the AU can be moved to an accessible

location.

3. On top of the AU, remove the cover screws and lift out the cover panel.

4. Remove the harness plug from the top of the UV bulb by pulling up gently.

5. Remove the two screws that secure the bulb bracket to the AU cover.

6. Remove the two screws that secure the bulb brace to the bracket.

7. Pull the old bulb up through the bulb bracket to complete the removal process.

8. Place the new bulb in the bulb bracket by sliding it through the vacant hole.

9. Insert the two screws that secure the bulb brace to the bracket.

10. Insert the two screws that secure the bulb bracket to the AU cover.

11. Insert the harness plug from the base of the UV Bulb by pushing down gently.

12. On top of the AU, slide in the cover panel and insert the cover screws.

13. Write today’s date on the appropriate sticker as a reminder to replace the bulb again a year from this date.

14. Dispose of the old bulb according to local regulations and codes.

Figure 7: Components of the Breathe Easy Retrofit Kit

NOTE

The bulb will still glow blue after 9,000 hours of use, but the UV radiation will not be strong enough to be functional. If the bulb

is glowing red or orange instead of a bright purple-blue, the bulb needs to be replaced immediately.

NOTE

The photocatalytic nano-mesh material does not need to be replaced.

DANGER

Shock hazard. Turn off all power breakers running to AU unit before removal of any part of the airhandler.

CAUTION

Bulb contains hazardous materials and should be disposed of according to local regulations and codes.
