WARNING
This symbol is used to alert the user to the presence of important operating and maintenance instructions in the literature accompanying this instrument.

Getting Started

D-TEK CO2 is shipped with the infrared cell and battery already installed. The battery must be charged before using D-TEK CO2.
Charging the Battery
Connect the supplied AC wall charger or DC car charger to the D-TEK CO2 power jack and the appropriate power source to charge the battery. While charging, the Charge indicator will flash Allow at least 10 hours to fully charge the battery The Charge indicator will illuminate when the battery is fully charged or after12 hours of charging Low battery is indicated by the green power indicator flashing When the battery is fully depleted, D-TEK CO2 will turn OFF and the green power indicator, the last yellow leak indicator, and the Charge indicator will flash NOTE: You should expect approximately 6½ hours of operation from a fully charged battery. Connect D-TEK CO2 to the AC wall charger to leak-check while charging the battery. The battery does not need to be fully charged to operate or fully depleted to charge.
NOTE: If the power indicator, HI, and LO indicators alternate flashing while the wall charger is connected, the battery may be unplugged or the connector is backward. This could also indicate a faulty battery.
WARNING
Only use car or wall chargers supplied by INFICON and designed for D-TEK CO2. Using other chargers may damage the instrument.
Using Your INFICON D-TEK CO2
WARNING
DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF GASOLINE, NATURAL GAS, PROPANE, OR OTHER COMBUSTIVE ATMOSPHERES. Using D-TEK CO2 is simple. Press the power button once to turn the detector ON. The green power indicator will illuminate, and the yellow leak indicators will illuminate from left to right in a scrolling fashion while the infrared cell warms up (approximately 60 seconds). When the detector is ready for use, the yellow leak indicators will extinguish and a steady beeping will begin. Long press the Power button to turn D-TEK CO2 OFF.
D-TEK CO2 is highly selective for CO2 (carbon dioxide). The atmosphere has 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 D-TEK CO2. When the headphones are plugged into the detector, the audio signal will only be heard through the headset.
WARNING
ONLY USE HEADPHONE SETS SUPPLIED BY INFICON. SERIOUS HEARING DAMAGE MAY OCCUR IF OTHER HEADPHONE SETS ARE USED.
Finding Leaks

1. Press the HI/LO button until the HI indicator is illuminated.

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. D-TEK CO2 only responds to changes in concentration of CO2 from the leak. Moving the probe permits the instrument to respond properly to these changes.

4. Watch for the yellow leak indicators to illuminate, and listen for a tone. When the instrument detects a leak source, the yellow leak indicators will illuminate and it will emit a different audible tone.

5. When 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 HI/LO button once to switch to LO sensitivity before repositioning the probe at the suspected leak source. The LO sensitivity setting helps find the exact site when a leak is large.

7. Once you have isolated the leak source, press the HI/LO button to return the sensitivity setting to HI to continue using D-TEK CO2.

8. When you have finished leak-testing, long press the power button to turn D-TEK CO2 OFF.

Auto Zero Mode
D-TEK CO2 by default will automatically zero to the background, allowing you to search for a higher concentration and help pinpoint the leak source. For example, if a leak is detected and D-TEK-CO2 is held in that area for several seconds, the alarm will stop. This indicates the unit has zeroed to the new background. It will now take a larger concentration of CO2 to cause an alarm. Holding D-TEK CO2 in clean air (no CO2) for several seconds will reset the zero point to normal.
Manual Zero Mode
D-TEK CO2 can be changed to manual mode, which disables the auto zero feature and allows the user to manually zero to the current background.
NOTE: For best performance, allow D-TEK CO2 to warm up for 5 to 10 minutes before enabling manual zero modes.

1. To enable manual zero modes, press and hold the HI/LO button for 5 seconds. The HI and LO indicators will flash quickly for several seconds followed by a steady flashing of the HI indicator when manual zero modes is active.
2. Press the HI/LO button to zero to the current background. The HI and LO indicators will flash quickly while D-TEK CO2 zeros. NOTE: While in manual zero modes, it is best to periodically zero to the current background even if a leak is not detected.
3. To return to auto mode, press and hold the HI/LO button until the HI indicator becomes steady.
   NOTE: When D-TEK CO2 is turned ON, it will always default to auto zero mode.

Changing the Filter Cartridge
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 D-TEK CO2.
NOTE: Water or oil will not penetrate the filter material, but will prevent airflow through the filter and affect sensitivity.
CAUTION
Always operate D-TEK CO2 with a filter cartridge installed. Operating without a filter can cause serious damage to the instrument.

1. Ensure D-TEK CO2 is OFF.

2. With the probe tip pointing downward, unscrew and remove the probe cap.
   NOTE: Do not allow moisture or dust to get into the probe.

3. Pull out the used filter cartridge and discard it.

4. Install a new filter cartridge. 5. Screw on the probe cap (do not overtighten).
   NOTE: Always use a new filter. Do not attempt to clean or disassemble a filter cartridge.

Changing the Infrared Cell

WARNING
COMPONENTS MAY BE HOT. DO NOT REMOVE THE IR CELL ACCESS DOOR WHILE D-TEK CO2 IS TURNED ON OR PLUGGED IN. 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. All leak indicators will flash when the IR cell has reached the end of its useful life.
To replace the IR cell:

1. Ensure D-TEK CO2 is OFF and not connected to any car or wall outlets.
2. Locate on the top cover (at the rear of the detector) the latch for the IR cell door.
3. Using a small screwdriver, pull the latch forward and remove the door.
4. Pull the IR cell straight out by grasping both edges of the label and pulling evenly. Discard the old IR cell appropriately, in accordance with local regulations.
5. Remove the replacement IR cell from the protective package.
6. 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.

Replacing the Battery

1. Ensure D-TEK CO2 is OFF and not connected to any power source.

2. With one hand, firmly press the square release buttons on either side of the rubberized grip.

3. With the release buttons pressed, remove the battery door by pulling it out from the bottom of the instrument.
   NOTE: Wiggling the battery door may help.

4. Carefully unplug the electrical connector by pulling it straight out.

5. Slide the battery out and discard it appropriately, in accordance with local regulations.

6. Slide a new battery in where the old battery was removed.

7. Carefully connect the electrical connector.

8. Squeeze the battery door tabs and replace the battery door.
   NOTE: Ensure the battery wires are clear of the battery door.

9. Connect D-TEK CO2 to a car or wall charger and allow the battery to charge for 10 to 12 hours to ensure a full charge.
   NOTE: If the power indicator, HI, and LO indicators alternate flashing while the wall charger is connected, the battery may be unplugged or the connector is backward. This could also indicate a faulty battery.
