The D-TEK CO2 is shipped with the infrared cell and power stick installed. The
nickel/metal hydride batteries in the power stick are not yet charged. To charge
them, connect the cord of the AC power adapter to the power jack at the rear of
the instrument, and plug the adapter into the appropriate mains outlet. The battery
charging light (rear left side) will flash when the detector is charging, changing to
steady illumination when the power stick is charged. Allow 10 hours for the full
charge.
NOTE: You should expect 6½ hours of operation from a fully charged power stick.
The D-TEK CO2 will operate on the AC power adapter.

Using Your INFICON D-TEK CO2
WARNING
WARNINGWARNING
WARNING
WARNINGWARNING
DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF
GASOLINE, NATURAL GAS, PROPANE, OR IN OTHER
COMBUSTIVE ATMOSPHERES.
Using the D-TEK CO2 is simple. Press the power switch once to turn the detector
ON. The green ON indicator lamp will illuminate, and the yellow indicator lamps
will illuminate from left to right in a running fashion while the infrared cell warms up
(approximately 60 seconds). When the detector is warmed up and ready for use,
the yellow lamps stop illuminating and you will hear an audible beeping.
The D-TEK CO2 is highly selective for CO
a natural background concentration of carbon dioxide of approximately 0.035%.
To prevent false alarms, it may be necessary to take steps to limit changes in this
background concentration from sources such as vehicle exhaust or your own
breath.
Headphone sets may be used with the D-TEK CO2. When the headphones are
plugged into the detector, the audio signal will only be heard through the headset.
ONLY USE HEADPHONE SETS SUPPLIED BY INFICON, PART
#032-0404. SERIOUS HEARING DAMAGE MAY OCCUR IF OTHER
HEADPHONE SETS ARE USED.

Finding Leaks
1. Press the right hand switch until the HI sensitivity setting is indicated by the
amber LED
2. Place the tip of the leak-detector probe close to the site of the suspected leak.
Try to position the probe within 1/4 inch of the possible leak source.
3. Slowly (approximately 1-2 inches per second) move the probe past each
possible leak point.
NOTE: It is important to move the tip of the probe past the leak to get a
correct reading. The D-TEK CO2 only responds to changes in
concentration of the refrigerant from the leak. Moving the probe
permits the instrument to respond properly to these changes.

4. Watch for the yellow lamps to illuminate, and listen for a tone. When the
WARNING
WARNINGWARNING
instrument detects a leak source, its yellow lamps will illuminate and it will emit
a different audible tone.
5. When the D-TEK CO2 signals a leak, pull the probe away from the leak for a
moment, then bring it back to pinpoint the location.
6. If the concentration of carbon dioxide is high, press the sensitivity switch once
to change the threshold level to the LOW sensitivity setting before repositioning
the probe at the suspected leak source. The LOW sensitivity setting helps find
the exact site when a leak is large.
7. Once you have isolated the leak source, return the sensitivity setting to HIGH
to continue using the D-TEK CO2.
8. When you’ve finished leak-testing, turn OFF the instrument.
Recharging the Power Stick
A fully charged power stick should provide power for greater than 6½ hours of
continuous operation. To recharge the power stick, use one of the instrument’s
power cords.
NOTE: The D-TEK CO2 does not need to be fully charged to operate.
Additionally, the power stick does not need to be fully discharged before
recharging.
DO NOT ATTACH ANY OTHER POWER CORDS TO THE D-TEK
CO2’S POWER JACK EXCEPT THE AC POWER ADAPTER AND
DC CORDS DESIGNED FOR THIS INSTRUMENT.
Connect the AC power adapter cord to the instrument and plug the adapter
into a working outlet, OR,
Connect the cigarette lighter adapter to the D-TEK CO2 and tap the power
from your vehicle’s battery.
The battery charging indicator (rear left side) will flash when the power stick is
charging, changing to steady illumination when the power stick is fully charged.
Allow 10 hours for a full charge.

Changing the Filter Cartridge
CAUTION
WARNING
WARNINGWARNING
The D-TEK CO2 utilizes a specially designed filter cartridge that fits into a
protective cap. The filter cartridge should be changed when it appears dirty or
when substances trapped in the filter cartridge seem to be affecting the sensitivity
of the D-TEK CO2.
NOTE: Water or oil will not penetrate the filter material but will prevent airflow
through the filter and affect sensitivity.
TURN OFF THE D-TEK CO2 AND HOLD THE PROBE WITH THE
FILTER TIP POINTING DOWN WHEN REMOVING THE FILTER CAP.
To change the filter cartridge, twist off the protective cap. Remove and dispose of
the used filter cartridge. Do not allow any moisture or dust to get into the probe.
Do not disassemble or attempt to clean the material inside the filter cartridge, as it
can be damaged when handled.
Slide a new filter cartridge into the cap. Twist the cap with the new filter cartridge
onto the probe base until it is tight.
NOTE: It is very important that you operate the D-TEK CO2 with a filter cartridge
installed at all times. Failure to do so could damage the leak detector's
components.
Changing the Infrared Cell
COMPONENTS MAY BE HOT. TURN OFF DETECTOR AND
DISCONNECT POWER ADAPTER CORD BEFORE REMOVING
THE INFRARED CELL DOOR.
The D-TEK CO2’s infrared cell (IR cell) is located in the body of the detector. The
IR cell is a complete assembly consisting of a metal tube, connectors and
electronic components. The IR cell is not designed to be taken apart. Doing so will
destroy the cell. This specialized IR cell will operate for about 800 hours.
The D-TEK CO2 will flash all the leak indicators when the IR cell has reached the
end of its useful life. To replace the IR cell:
1. Locate on the top cover (at the rear of the detector) the latch for the IR cell door.
2. Using a small screwdriver, pull the latch forward and remove the door.
6
3. Pull the IR cell straight out by grasping both edges of the label and pulling
evenly.
4. Remove the replacement IR cell from the protective package.
5. Carefully align the male leads and air tubes on the IR cell with the connectors
mounted on the circuit board. Insert the leads into the sockets and push the IR
cell straight down.
NOTE: Ensure the lead connectors on the IR cell ends are not bent and the cell
is seated tightly.
Removing/Replacing the Power Stick
The D-TEK CO2 uses a preassembled power stick/battery.
Remove the battery compartment door on the back of the D-TEK CO2 by pressing
on both release buttons on the grip and pulling the door straight out. The power
stick is connected to the PCB board via a miniature electrical connector.
Disengage the connector and slide the power stick out of the D-TEK CO2.
To install a fresh power stick, slide the new stick into the D-TEK CO2 and push the
miniature connector on the power stick into the mating half on the PCB board.
Once the power stick is in place, close the battery compartment by aligning the
two tabs and sliding the door straight in until it latches. Ensure the wire leads on
the power stick are not pinched in the door. Allow 10 hours to fully charge the new
power stick.
NOTE: If unit does not power up after the power stick is replaced, verify that the
key connector on the power stick is mated properly to the connector on
the circuit board. Reverse the connection if necessary and power up
again. If the Hi/Lo indicators flash in a rapid, alternating manner when the
AC adapter is connected, the power stick is installed backwards.
