Changing the Infrared Cell
W A R N I N G
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.
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.
