GETTING STARTED
Installing Batteries
1. Remove the battery compartment door located on the bottom of the instrument as
shown above. Install batteries, Positive Polarity inwards (towards the unit).
(See figure 2).
3
OPERATING FEATURES
Constant Power Indication
The Constant Power indicator allows the user to see the battery level at all times.
TIF XL-1A - The Red LED will remain on whenever the unit is powered on. If the
LED is dim, or is not lit, this is an indication that the batteries should be replaced.
TIF RX-1A - The first LED (leftmost) in the bargraph will remain on whenever
the unit is powered on. If the LED is dim, or is not lit, this is an indication that the
batteries should be replaced.
Automatic Circuit/Reset Feature
Both detectors feature an Automatic circuit that sets the unit to ignore ambient concentrations of refrigerant. The RX-1A additionally features a Reset
function key for convenience.
• Automatic Circuit - Upon initial power on, the unit automatically sets itself to
ignore the level of refrigerant present at the tip. Only a level, or concentration,
greater than this will cause an alarm.
CAUTION: Be aware that this feature will cause the unit to ignore any refrigerant
present at turn on. In other words, with the unit off if you place the tip up to a
known leak and switch the unit on, no leak will be indicated!
• Reset Feature - Resetting the unit during operation performs a similar function, it
programs the circuit to ignore the level of refrigerant present at the tip. This
allows the user to 'home-in' on the source of the leak (higher concentration).
Similarly, the unit can be moved to fresh air and reset for maximum sensitivity.
Resetting the unit with no refrigerant present (fresh air) causes any level above
zero to be detected.
To Reset the unit:
XL-1A
- Switch the unit OFF and back ON again
RX-1A - Press the RESET key. Whenever the unit is reset, all LED's will light for 1
second. This provides a visual confirmation of the reset action.
Sensitivity Adjustment (RX-1A Only)
The TIF RX-1A provides two levels of sensitivity. The base beeping tone is an
indication of sensitivity level; the quicker beep rate indicates a higher level. When
the unit is switched on, it is set to the high sensitivity position.
1. To change the sensitivity, press the LO key. When the key is pressed, the visual
display will momentarily show the four left LED's red. The base beep rate will
slow, indicating Low Sensitivity level.
2. To switch back to High Sensitivity, press the HI key. The three right LED's will
light momentarily, and the base beep rate quickens.

OPERATING INSTRUCTIONS
1. Switch the unit on
XL-1A - Move the ON/OFF switch to the ON position.
RX-1A - Press the "I/O" (Red and Green) key. All LED's will light for two sec-
onds as the unit performs a self check.
2. The unit will begin beeping at a steady rate.
3. Verify the battery level by observing the constant power indicator (see above).
4. Begin searching for leaks. When refrigerant is detected, the audible tone will
change to a 'siren' type sound, distinctly different from the base beep rate.
RX-1A - Additionally, the visual indicators will light progressively as described in
the Alarm Indications section.
5. RX-1A - Sensitivity can be adjusted at any time during operation by using the HI
or LO keys.
6. If a full alarm occurs before the leak is pinpointed, RESET the unit as described
above, to reset the circuit to a zero reference.
OPERATING TIPS
The following section includes several general operating tips, and the SAE J1628
recommended procedure for leak detection.
1. In areas that are heavily contaminated with gas, the unit may be reset to block
out ambient concentrations of gas. The probe should not be moved while the
unit is being reset. The unit can be reset as many times as needed.
2. In windy areas, even a large leak can be difficult to find. Under these conditions,
it is best to shield the potential leak area.
3. Be aware that the detector may alarm if the sensing tip comes in contact with
moisture and/or solvents. Therefore, avoid contact with these when leak checking.
SAE J1628 Recommended Procedure
NOTE
: On Automotive A/C Systems, test with the engine not in operation.
1. The air conditioning or refrigeration system should be charged with sufficient
refrigerant to have a gauge pressure of at least 340 kPa (50 psi) when not in
operation. At temperatures below 15° C (59° F) leaks may not be measurable,
since this pressure may not be reached.
2. Take care not to contaminate the detector probe tip if the part being tested is
contaminated. If the part is particularly dirty, or condensate (moisture) is present
it should be wiped off with a dry shop towel or blown off with shop air. No cleaners or solvents should be used, since the detector may be sensitive to their
ingredients.
3. 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 should 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.
5
OPERATING TIPS
4. 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.
5. At each area checked, the probe should be moved around the location, at a rate
no more than 25 to 50 mm/second (1-2 in/second), and no more than 5 mm (1/4
in) from the surface, completely around the position. Slower and closer movement of the probe greatly improves the likelihood of finding a leak (see Fig. 3,
below). Any increase in beep rate is indicative of a leak.
Fig. 3
6. An apparent leak shall be verified at least once as follows:
a) Blow shop air into the area of the suspected leak, if necessary, and repeat the
check of the area. In cases of very large leaks, blowing out the area with shop
air often helps locate the exact position of the leak.
b) First move the probe to fresh air and reset. Then hold the probe tip as close
as possible to the indicated leak source and slowly move around it until the leak
is confirmed.
Automotive A/C Systems only -
7. Leak testing of the evaporator core while in the air conditioning module shall be
accomplished by turning the air conditioning blower on high for a period of 15
seconds minimum, shutting it off, then waiting for the refrigerant to accumulate in
the case for 10 minutes.
After such time, insert the leak detector probe into the blower resistor block or
condensate drain hole, if no water is present, or into the closest opening in the
heating/ventilation/air conditioning case to the evaporator, such as the heater
duct or a vent duct. If the detector alarms, a leak apparently has been found.
All Systems -
8. Following any service to the refrigerant system and any other service which disturbs the refrigerant system, a leak test of the repair and of the service ports of
the refrigerant system should be done.

APPLICATIONS
Both of the Leak Detectors covered by this manual may be used to:
• Detect refrigerant gas leaks in Air Conditioning or Refrigeration systems and
storage/recover containers. These detectors will respond to ALL halogenated
(contains Chlorine or Fluorine) refrigerants. This includes, but is not limited to:
CFCs e.g. R12,R11,R500,R503 etc...
HCFCs e.g. R22,R123,R124,R502 etc...
HFCs e.g. R134a, R404a, R125 etc...
Blends such as AZ-50, HP62, MP39, R410a etc...
• Detect Ethylene Oxide gas leaks in hospital sterilizing equipment (detects halo-
genated propellant)
• Detect SF-6 in high voltage circuit breakers
• Detect most gases that contain Chlorine, Fluorine and Bromine (halogen gases)
• Detect cleaning agents used in dry cleaning applications such as
perchloroethylene.
• Detect Halon gases in fire extinguishing systems
MAINTENANCE
Proper maintenance of your Leak Detector is very important. Carefully following the
instructions, outlined below, will reduce performance problems and increase the life
expectancy of the unit.
WARNING: TURN UNIT OFF BEFORE REPLACING THE SENSING TIP. FAILURE
TO DO SO MAY RESULT IN A MILD ELECTRICAL SHOCK!
Keep the sensing tip clean: Prevent dust, moisture and grease build-up by utilizing
the provided tip protector. Never use the unit without the protector in place.
Before using the unit always inspect the tip and protector to see that they are free of
dirt and/or grease. To clean:
1. Remove protector by grasping and pulling off tip.
2. Clean protector with shop towel and/or compressed air.
3. If the tip itself is dirty it can be cleaned by immersing in a mild solvent, such as
alcohol, for a few seconds, and then using compressed air and/or a shop towel
to clean.
NOTE: Never use solvents such as gasoline, turpentine, mineral spirits, etc... as
these will leave a detectable residue and desensitize your unit.
Sensing tip replacement: The tip will eventually wear out and require replace-
ment. It is difficult to predict exactly when this will occur since tip longevity is directly
related to the conditions and frequency of use. The tip should be replaced whenever
the alarm sounds or becomes erratic, in a clean, pure, air environment.

MAINTENANCE
To replace the tip:
1. Make sure the unit is OFF.
2. Remove the old tip by unscrewing counter-clockwise.
3. Use the supplied replacement tip, located in the carrying case. Replace by
screwing on clockwise.
