Getting Started

1. Install the batteries and sensor as described below.

2. Slide the OFF-LOW-HIGH Sensitivity switch to the HIGH

position.

3. Wait for the TEK-Mate to warm up. A high-pitched audible tone

will be heard and the “LEAK”indicator will be illuminated while

the TEK-Mate is warming up. When this tone changes to a chirp

and the “LEAK”indicator starts ﬂashing, the TEK-Mate is ready

to ﬁnd leaks.

4. Begin checking for leaks.

The INFICON TEK-Mate Refrigerant Leak Detector provides similar

responses to all CFC's, HCFC's, HFC's and refrigerant blends (i.e.

R-404A, R407c) as well as SF6. There is no need to select the

refrigerant you're working with.

How to Install the Alkaline Batteries

1. Remove the battery cover by releasing the latch and sliding the

cover down and off the handle.

2. Install two “D”size alkaline batteries as shown in Figure 1.

3. Reinstall the battery cover by aligning it with the handle and

sliding it up until the latch engages.

When the batteries are nearing the end of their useful life, the yellow

Low Battery indicator illuminates. While the batteries may operate

the TEK-Mate up to a period of one hour after the Low Battery

indicator illuminates, the batteries should be replaced as quickly as

possible.

Figure 1. Properly Installed Alkaline Batteries

How to Install or Change the Sensor

A new TEK-Mate is shipped with its sensor packed separately. The

sensor must be installed in the TEK-Mate before use. This

specialized sensor will operate for about 100 hours before it will

need to be replaced.

1. Remove the rubber sensor cover by lifting at the outer edge.

2. If you are replacing a worn out sensor, remove the worn out

sensor by pulling it straight out of the socket and discard it.

WARNING

If you are replacing the sensor, the worn out sensor

may be hot.

3. Remove the new sensor from its packaging.

4. Carefully align the three sensor leads (small wires coming out of

the bottom of the “can”) with the three holes in the sensor socket.

Insert the leads into the holes by gently pressing straight down

on the sensor until the sensor leads contact the bottom of the

socket. Be careful not to bend the sensor leads. See Figure 2.

5. Reinstall the rubber sensor cover by pressing it down ﬁrmly

around the edges. Be sure the edges of the cover are ﬂat against

the surface of the detector.

WARNING

Do not operate this instrument in the presence of

gasoline, natural gas, propane, or in other

combustible atmospheres.

How To Find Leaks

NOTE: A sudden whipping of the leak detector probe or "blowing"

into the sensor tip will affect the air ﬂow over the sensor and

cause the instrument to alarm.

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 (5 mm) of the possible leak source.

2. Slowly (approximately 1 to 2 inches/second (25 to 50

mm/second)) move the probe past each possible leakage point.

NOTE: It is important to move the tip of the probe past the

leak. If held on a leak, the auto zero feature will

gradually zero out the leak signal.

3. When the instrument detects a leak source, it will emit a different

audible tone.

4. When the TEK-Mate signals a leak, pull the probe away from the

leak for a moment, then bring it back to pinpoint the location. If

the refrigerant leak is large, setting the sensitivity switch to LOW

will make it easier to ﬁnd the exact site of the leak.

5. Return the sensitivity switch to HIGH before searching for

additional leaks.

NOTE: When you reset the instrument to HIGH, as when you

turn it on initially, the tone will sound continuously then

give way to a chirp.

6. When you've ﬁnished leak-testing, turn OFF the instrument and

store it in a clean place, protected from possible damage.

How To Change the Filter

The foam ﬁlter at the probe tip should be replaced if it becomes

plugged with water or oil. To replace the ﬁlter, simply pull out the old

ﬁlter (with a paper clip or similar device). Then, push in the new ﬁlter.

Cleaning The TEK-Mate's Housing

The TEK-Mate'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

TEK-Mate from contact with these substances.

Disposing Of The Alkaline Batteries

At the end of the life of a set of alkaline batteries, please dispose of

them according to applicable state and local regulations. In the

absence of such regulations, Inﬁcon encourages its customers to

recycle and/or dispose of the cells through voluntary waste recycling

programs.

Troubleshooting

Except for the batteries and the sensor, the internal parts of the

TEK-Mate Leak Detector are not user serviceable. If you experience

a problem with your TEK-Mate, see the Troubleshooting Table below

to determine how to remedy the problem. If you can not remedy the

problem, take your TEK-Mate to your wholesaler for warranty

evaluation.

PROBLEM CAUSE REMEDY

1. Poor sensitivity.

The TEK-Mate does

not ﬁnd leaks.

1a. Sensor has

reached the end of its

useful life.

1a. Replace the sensor. See

page 5.

1b. Power switch set

to LOW instead of

HIGH

1b. Set the Power Switch to

HIGH and scan for the leak

again.

2. The TEK-Mate

responds slowly to a

leak.

2a. Dirty or wet ﬁlter. 2a. Replace the ﬁlter. See

page 7.

2b. Failure in the

pumping system.

2b. Turn the TEK-Mate on

and listen for a high-pitched

motor sound. If you do not

hear the motor, return the

TEK-Mate to your

wholesaler for warranty

evaluation.
