Getting Started
D-TEK Select is shipped with the infrared cell and power stick installed. The
nickel/metal hydride batteries in the power stick are not yet charged. To charge
them, connect the cord of the AC power adapter to the power jack at the rear of
the instrument, and plug the adapter into the appropriate mains outlet. The battery
charging light (rear left side) will flash when the detector is charging, changing tosteady illumination when the power stick is charged. Allow 10 hours for the fullcharge.
NOTE:

Expect approximately 6.5 hours of operation from a fully charged power
stick. D-TEK Select will operate off the AC power adapter. Connecting the
supplied AC power adapter will allow operation of the detector while thepower stick charges.

Using Your INFICON D-TEK SelectWARNING
Do not operate this instrument in the presence of gasoline,
natural gas, propane, or in other combustive atmospheres.
Using D-TEK Select is simple. Press the power switch once to turn the detector
ON. The green ON LED will illuminate, and the yellow LEDs will illuminate fromleft to right in a scrolling fashion while the infrared cell warms up (approximately
60 seconds). When the detector is warmed up and ready for use, the yellow LEDs
extinguish and a steady beeping is heard.
D-TEK Select provides similar responses to all CFCs, HCFCs, HFCs, andrefrigerant blends (i.e., R-404A, R407C, R-410A) as well as SF6. There is noneed to select the desired refrigerant.
NOTE:

D-TEK Select does not detect R-11 due to the particular physicalproperties of this refrigerant.

5

Headphone sets may be used with D-TEK Select. When headphones are used,alarms are only heard through the headphones.

WARNING
Only use headphone sets supplied by INFICON. 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 thesuspected leak. Try to position the probe within 1/4 inch (0.5 cm) of the possible
leak source.
2. Slowly (approximately 1 - 2 inches (2.5 - 5 cm) per second) move the probe pasteach possible leak point.
NOTE:

It is important to move the tip of the probe past the leak to get acorrect reading. D-TEK Select only responds to changes inconcentration 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 LEDs will illuminate andit will beep rapidly.
4. When D-TEK Select signals a leak, pull the probe away from the leak for a
moment, then bring it back to the location to pinpoint the leak.
5. If the concentration of the refrigerant gas is high, press the sensitivity switch tochange to the LOW sensitivity setting. The LOW sensitivity setting helps find theexact site when a leak is large.
6. Once the leak source is isolated, return the sensitivity setting to HIGH tocontinue using D-TEK Select.
7. When leak checking is complete, press the Power switch to turn D-TEK SelectOFF.

Using the Manual Zero Mode
D-TEK Select's automatic suppression of background contamination can bedisabled, allowing for the continuous display of a leak without "zeroing it out."
When D-TEK Select is set in the manual zero mode, the user may manually resetor zero the detector.
To initialize this function, press and hold the HI/LO switch for 5 seconds. The "HI"sensitivity indicator will flash to alert the user the detector is in manual zero mode.
Increases in concentrations of refrigerants will be displayed by the illumination of
the yellow LEDS. For best test results, allow D-TEK Select to warm up for
5 to 10 minutes before engaging manual zero mode.
To "zero" D-TEK Select, press the HI/LO switch once. Both the HI and LO
sensitivity indicators will flash for a few seconds while the detector measures andsets a new background base level. Any increase in concentrations of refrigerant
above this base level will be displayed.
To turn off the manual zero mode, press and hold the HI/LO switch until the HI
sensitivity indicator becomes steady.
NOTE:

When D-TEK Select is turned on, it will always default to automatic
zeroing mode.

7

Recharging the Power Stick
A fully charged power stick should provide power for approximately 6.5 hours ofcontinuous operation. When the battery is fully depleted, D-TEK Select will shut
down. To show the battery is depleted, the green ON LED, the last yellow leak
LED, and the amber battery charging LED will flash. Recharge the D-TEK Selectby connecting the supplied AC power adapter or cigarette lighter adapter.
NOTE:

D-TEK Select does not need to be fully charged to operate nor fullydischarged before recharging.

WARNING
Do not attach any other power cords to D-TEK Select’s power jackexcept the AC power adapter and DC cords designed for this
instrument.
The battery charging indicator (rear left side) will flash when the power stick ischarging, changing to steady illumination when the power stick is fully charged.
Allow 10 hours for a full charge.
D-TEK Select will operate using the AC power adapter. Connecting the supplied
AC power adapter will allow operation of the detector while the power stickcharges.

8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 whensubstances 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.

CA UT I O NTurn off D-TEK Select and hold the probe with the filter tip
pointing down when removing the filter cap.
To change the filter cartridge:
1. Twist off the protective cap.
2. Remove and dispose of the used filter cartridge.
NOTE:

Do not allow any moisture or dust to get into the probe. Do notdisassemble or attempt to clean the material inside the filter cartridge, as
it can be damaged when handled.

3. Slide a new filter cartridge into the cap.
4. 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 installedat all times. Failure to do so could damage the leak detector's
components.

9Changing the Infrared CellWARNING
Components may be hot. Turn off the detector and disconnect thepower 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 theend 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.
3. Grasp the IR cell according to the directions printed on its label.
Pull it straight out so both ends are released at the same time.
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.

10Removing/Replacing the Power StickD-TEK Select uses a pre-assembled power stick.
Remove the battery compartment door on the back of D-TEK Select by pressing
on both release buttons on the grip and pulling the door straight out. The power
stick is connected to the PCB board via a miniature electrical connector.
Disengage the connector and slide the power stick out of D-TEK Select.
Slide the new power stick into D-TEK Select and push the miniature connector on
the power stick into the mating half on the PCB board. Do not bend the PCB
board’s connector away from the board. Once the power stick is in place, close
the battery compartment by aligning the two tabs and sliding the door straight in
until it latches. Ensure the wire leads on the power stick are not pinched in thedoor. Allow 10 hours to fully charge the new power stick.
NOTE:

If D-TEK Select does not power up after the power stick is replaced,
check that the key connector on the power stick is mated properly to theconnector on the circuit board. Reverse the connection if necessary andpower up again. If the HI/LO indicators flash in a rapid, alternating manner
when the AC adapter is connected, the power stick is installedbackwards.
