Removing/Replacing the Power Cells (Continued)
To install fresh power cells, check the polarity label inside the
power-cell compartment, and insert the positive (button) end of
each power cell first, as shown. Once the power cells are in place,
close the battery compartment by aligning the two tabs and sliding
the door straight in until it latches.
Cleaning the D-TEK’s Housing
The D-TEK’s plastic housing can be cleaned with standard
household detergent or isopropyl alcohol. Care should be taken to
prevent the cleaner from entering the instrument. Since gasoline
and other solvents may damage the plastic, protect your INFICON
D-TEK from contact with these substances.
Troubleshooting
Note:
The internal parts of the D-TEK Leak Detector are not serviceable.
Opening the plastic housing for any reason will void the warranty.
Problem
Low sensitivity, the leak detector is slow to respond to a leak or the
leak detector will not “pick up” refrigerant.
Diagnostics/Remedy
This problem can be caused by broken or shorted wire in the
probe, by a failure in the pumping system or by a sensor that has
burned out.
To identify which area may be the problem you should:
• Turn your D-TEK on and verify the pump is running by listening
for a high pitched motor sound. If you do not hear this sound,
the pump system has failed.
