Warranty and Liability
INFICON warrants your TEK-Mate Refrigerant Leak Detector to be free from defects of
materials or workmanship for two years from the date of purchase. INFICON does not warrant
items that deteriorate under normal use, including power cells, sensors and filters. In addition,
INFICON does not warrant any instrument that has been subjected to misuse, negligence, or
accident, or has been repaired or altered by anyone other than INFICON.
INFICON's liability is limited to instruments returned to INFICON, transportation prepaid, not
later than thirty (30) days after the warranty period expires, and which INFICON judges to have
malfunctioned because of defective materials or workmanship. INFICON's liability is limited to,
at its option, repairing or replacing the defective instrument or part.
This warranty is in lieu of all other warranties, express or implied, whether of merchantability or
of fitness for a particular purpose or otherwise. All such other warranties are expressly
disclaimed. INFICON shall have no liability in excess of the price paid to INFICON for the
instrument plus return transportation charges prepaid. INFICON shall have no liability for any
incidental or consequential damages. All such liabilities are excluded.
Special Information For Automotive Technicians
INFICON's TEK-Mate Refrigerant Leak Detector Model #705-202-G1 is design certified by MET
Laboratories, Inc. to meet SAE J1627, “Rating Criteria for Electronic Refrigerant Leak
Detectors” for R12, R22, and R134a. The following SAE Recommended Practice applies to this
instrument and to the use of generally available electronic leak detection methods to service
motor vehicle passenger compartment air conditioning systems.
1. The electronic leak detector shall be operated in accordance with the equipment
manufacturer's operating instructions.
2. Leak test with the engine not in operation.
3. The A/C system shall be charged with sufficient refrigerant to have a gauge pressure of at
least 50 PSI (340 kPa) when not in operation. At temperatures below 59 °F (15 °C) leaks
may not be measurable, since this pressure may not be reached.
4. Take care not to contaminate the detector probe tip if the part being tested is contaminated.
If the part is particularly dirty, it should be wiped off with a dry shop towel or blown off with
shop air. No cleaners or solvents shall be used, since many electronic detectors are sensitive
to their ingredients.
5. Visually trace the entire refrigerant system, and look for signs of air conditioning lubricant
leakage, damage, and corrosion on all lines, hoses, and components. Each questionable
area shall be carefully checked with the detector probe as well as all fittings, hose-to-line
couplings, refrigerant controls, service ports with caps in place, brazed or welded areas, and
areas around attachment points and hold-downs on lines and components.
6. Always follow the refrigerant system around in a continuous path so that no areas of potential
leaks are missed. If a leak is found, always continue to test the remainder of the system.
7. At each area checked, the probe shall be moved around the location, at a rate no more than
1 to 2 inches/second (25 to 50 mm/second) and no more than 1/4 inch (5 mm) from the
surface completely around the position. Slower and closer movement of the probe greatly
improves the likelihood of finding a leak.
