Using Your INFICON D-TEK Select
WARNING
DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF
GASOLINE, NATURAL GAS, PROPANE, OR IN OTHER
COMBUSTIVE ATMOSPHERES.
Using the D-TEK Select 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 extinguish and you will hear a steady beeping.
The D-TEK Select provides similar responses to all CFC’s, HCFC’s, HFC’s and
refrigerant blends (i.e., R-404A, R407C, R-410A) as well as SF6. There is no
need to select the refrigerant you’re working with.
NOTE: The D-TEK Select does not detect R-11 due to the particular physical
properties of this refrigerant.
Headphone sets may be used with the D-TEK Select. 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, PART
#032-0404. SERIOUS HEARING DAMAGE MAY OCCUR IF OTHER
HEADPHONE SETS ARE USED.
Finding Leaks
1. Place the tip of the leak-detector probe as close as possible to the site of the
suspected leak. Try to position the probe within 1/4 inch of the possible leak
source.
2. 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 Select only responds to changes in
concentration of the refrigerant from the leak. Moving the probe
permits the instrument to respond properly to these changes.
3. When the instrument detects a leak source, its yellow lamps will illuminate and
it will emit a different audible tone.
