Before installing the CX3000 purifier, inspect for any signs of damage.
During handling and installation, take care to protect the catalytic hon-
eycomb side of the product from physical damage, as the aluminum-tita-
nium core is very soft and can be easily damaged.
Warning - Always unplug the power cord from the CX3000 air purifier when
changing the filter or ultraviolet lamps. Never look into a burning ultravi-
olet lamp without proper eye protection as severe damage to the eyes can
result. This product is rated for standard ambient air temperatures during
heating and air-conditioning functions and not rated for elevated air tem-
peratures in excess of 125 degrees fahrenheit.
Do not attempt to clean the catalytic honeycomb core with cleaning
solutions. The catalyst is radiated with short wave ultraviolet light during
periods of non-air flow and is self-cleaning.
Do not install insulation within 76MM or 3 inches of Luminaries.
Access for service is required when mounting above ceilings or behind
walls.
Do not install in a position where the interior module can fall from an
elevated position and cause injury to people or equipment below.

OPERATION
The CX3000 installs in the air-inlet side of any heating and air conditioning system, up to five tons in size. Operation of the air-handler fan
unit is required for air purification and sterilization to take place.
Note: The ultraviolet lamps are wired to operate continuously. This feature allows the catalyst to burn off surface impurities, while cleaning and
reactivating itself during periods of no airflow. The cost of operation is
less than .07 cents per day. See operating cost section.
The CX3000 combines three unique technologies to protect people
against indoor air pollutants. Photo-Catalytic Titanium Oxidation, combined with high efficiency electrostatic MERV-11 particulate filtration,
and germicidal ultraviolet lights, quickly reduce and eliminate toxic gas
phase chemicals, lung damaging dust and airborne germs from the living
environment.
Many new homes have smart programmable thermostats that allow for
automatic operation of the air-handler fan unit when there is no demand
for heating or air conditioning. It is important that the CX3000 operates
at least (25) minutes per hour (24) hours per day to remove toxic materials from the indoor environment.
The length of operation depends on the location of the home or office in
relation to point source pollution such as refineries, processing plants,
automobile traffic, and areas that produce high levels of pollen.
Individuals that are sensitive to mold spores, dust mites and chemicals, or
have respiratory problems such as asthma, emphysema, and chronic allergies, should extend the run time to at least (40) minutes per hour.
To obtain maximum benefit from the CX3000 air purification system, it is
recommended that the air-handler fan be set to run continuously.

Fan unit on 30 minutes per hour Air cycled (63) ------- times per day
Note: In the event the existing thermostat does not have the capability to
operate the air-handler fan unit independently of a demand for heating or
air-conditioning, it is highly recommended that an (Air Cycler) be
installed.
This device is simply wired in parallel with the existing thermostat wire
and can be programmed to turn on the air handler fan unit for any desired
interval. A memory tracks the time the fan unit operates every hour and
only cycles the fan unit that hour if normal requirements for heating and
air conditioning have not cycled the fan unit long enough to meet air
purification requirements.
The Air Cycler can be sourced from Shelter Supply, Lakeville, MN (1-800-
762-8399) or (www.Air Cycler.com) on the web.
Electricity cost

During periods where the fan unit is being operated for the sole purpose
of air purification, running a 1/2 horsepower fan unit will add approxi-
mately $5.36 per month to the normal operating cost. However, this cost
is easily offset in savings on medication, doctors office visits, mechanical
maintenance and cleaning of fan units, refrigeration coils, dirty air ducts,
and last but not least, less house cleaning.

1 . Remove filter as in Fig. - 1.
2. Reach inside and rotate UV lamp 1/4 turn in either direction and
remove. Fig. - 3
3. Carefully place new lamp back into inner case so that the pins line up
with the slot on lamp holders at each end. Fig. - 4
4. Slide the new lamp down into the lamp holders and rotate 1/4 turn.
5. Replace filter and slide module into outer case. Tighten locking knobs
finger-tight.
6. IMPORTANT: Make sure AIR FLOW arrow on filter is facing the air-
inlet side of the air handler.
7. Plug in power cord and check sight ports for lamp illumination.
SERVICE
The CX3000 comes with a built-in computerized service panel to automatically keep track of service intervals. Indicator lights will tell you when to
change filter and ultraviolet lamps (30) days in advance.
MERV-11 Filter . . . . . change every (6) months . . . . . service light turns
from green to yellow after five months, and to red after six months.
UV Lamps . . . . . change every (12) months . . . . . service light turns
from green to yellow after eleven months, and to red after twelve
months.
CHANGING THE FILTER
1 . Unplug the power cord from the CX3000. Unscrew the two locking
knobs and pull out the inner module.
2. Loosen Phillips head screws on filter retainer plates and remove
plates - Fig - 1
3. Remove old filter and replace with new filter. Make sure airflow
arrow on filter is pointing to the inside of module.
4. Replace filter retainer plate and tighten Phillips head screws.

1. Unscrew the two locking knobs and remove the inside module from
the outer case.
2. Take care not to bend or distort the outer metal enclosure.
3. Mount the outer case to the support plenum. Note: Do not use a
screw length that will extend into or penetrate the inside module
containing the catalyst or filter.
4. In some cases, the foot print of the air handler may be larger or
smaller than the outer enclosure of the CX3000. A metal adapter
plate of 18 ga. sheet metal should be fabricated to make a suitable
transition. Fig. - 7
RESETTING THE SERVICE LIGHTS
On the right side of the service panel, there are arrows pointing to two
small holes marked RESET. One is marked FILTER, and one is marked
LAMP. Insert a pin or similar object into the hole corresponding to the
replacement component, and push lightly until the service light returns to
the green position. The computer is now reset. Fig. - 5
REPLACEMENT FILTERS AND ULTRAVIOLET LAMPS
Replacement components are available in the form of a yearly replacement kit,
comprising (2) filters and (1) set of UV lamps. Replacement kits are available from your local HVAC wholesaler.
INSTALLATION
Make sure to install the CX3000 so that the inlet, or return air, enters the
side containing the MERV-11 particle filter first. Fig. - 6
SERVICE PANEL

5. Tape all seams between the air handler and the outlet side of the
CX3000 so there can be no air bypassing the system.
6. Attach the air handler to the outlet side of the CX3000, and fasten with
#10 x 3/8 self-drilling sheet metal screws. NOTE: Only 1/2 inch of
clearance has been provided between the outer and inner case.
7. Slide the inner module into the outer encasement and tighten locking
knobs finger-tight. Make sure the inner module will freely slide in and
out of the outside enclosure.
8. Plug in the power cord to any 120vac outlet and check both sight ports
to make sure both lamps are illuminated. Ultraviolet lamps must remain
on at all times regardless of thermostat or Air Cycler settings.
9. Check the service panel. The LED lights should flash in sequence for 15
seconds and then return to green. The filter lamp should be flashing
green and the UV lamp light should be a steady green.
10. Set the thermostat or the Air Cycler to operate the fan unit for at least
25 minutes every hour. If air quality problems persist after one week,
increase the fan unit operating time by (5) minute intervals.
1. Unscrew the two locking knobs and remove the inside module from
the outer case.
2. Take care not to bend or distort the outer metal enclosure.
3. Mount the outer case to the support plenum. Note: Do not use a
