Changing the Filter Cartridge
D-TEK Select 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 affect the sensitivity.
NOTE: Water or oil will not penetrate the filter material but will prevent airflow
through the filter and affect sensitivity.

Turn off D-TEK Select 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 to operate D-TEK Select with a filter cartridge installed
at all times. Failure to do so could damage the leak detector's
components.
Changing the Infrared Cell
W A R N I N G
Components may be hot. Turn off the detector and disconnect the
power adapter cord before removing the infrared cell door.
D-TEK Select'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 approximately 1000 hours.
D-TEK Select will flash all the yellow leak LEDs when the IR cell has reached the
end of its useful life. To replace the IR cell:
1. Locate the latch for the IR cell door on the top cover (at the rear of the detector).
2. Using a small screwdriver, pull the latch forward and remove the door.
