WARNING: PERSONAL INJURY HAZARD
Do not use this Leak Detector in an explosive or combustible atmosphere. The
ambient atmosphere is drawn through the probe and sensor which operates at a very
high temperature.
The resulting hot mixture of air and combustible gas could explode.
Unpacking
Unpack the unit from the carton and carrying pouch. Refer to the Parts and Controls section
(page 3) for parts identification. You will find five (5) major components in the carrying case.
- Unit
- Battery pack
- Sensor
- Probe
- Battery charger
Before using your new leak detector for the first time, you will need to charge the batteries,
install the sensor and install the probe.
Installing and Charging Batteries
CAUTION: Batteries should only be charged in temperatures between 50ºF and 104ºF
(10ºC - 40ºC). Charging batteries outside this temperature range may cause
permanent damage to the batteries.
A new unit comes shipped with the battery pack partially installed and taped in place. Remove
the tape holding the battery pack, remove the battery pack, and then remove the tape and pack-
ing material inside the battery pack compartment, covering the battery socket.
Re-insert the battery pack, NOTING THE CORRECT ORIENTATION, indicated by the ‘rib’ and
square peg on one side of the pack and corresponding groove in the instrument’s compartment
(see Fig 2).
GETTING STARTED

Once the battery pack is installed, plug the charging unit into a wall outlet and connect the
charger jack to the unit (see Fig 3). When properly connected, the first LED will indicate the
charging status:
- Quickly flashing orange = battery charging
- Slowly flashing green = battery fully charged
- Slowly flashing red = failed batteries, cannot be recharged
New or completely discharged batteries will take approximately two (2) hours to fully re-charge.
When the LED indicates that the batteries are fully charged, the unit is ready for operation.
Sensor and Probe Installation
Anew unit comes shipped with the probe not installed on the unit and the sensor packaged in
a hermetically sealed foil bag.
1. Open the bag and remove the sensor.
2. Hold the unit with the front end facing you and note the sensor connection inside the
threaded bushing on the end of the unit. Note that there are five (5) holes corresponding to
the five (5) pins on the sensor – three (3) on the left and two (2) on the right (refer to Fig. 4).
3. Grasp the sensor and align the pins with the corresponding holes. CAUTION: the sensor can
only be inserted one way.
When properly aligned, firmly push the sensor into the
connector until it stops.
4. Install the flexible probe by screwing it clock-wise onto the threaded brass bushing around the
sensor until it is finger tight. Note: Do not bend the probe too sharply or the probe can be
damaged.
CAUTION: NEVER operate the unit without the flexible probe properly installed.
Sensor contamination, erratic performance and other problems may occur. Additionally,
the sensor will become quite hot during operation, which could be dangerous.

Your unit includes an array of operating features designed to increase usability and simplify user
interface. Please refer to the Parts and Controls diagram on page 3 to familiarize yourself with
the indi
cators and keypad controls as you proceed through this section.
A proper understanding of each key and its function will enhance your experience with this prod-
uct and allow you to get the most from its capabilities.
Constant Power Indication
The Constant Power indicator allows the user to see the battery level at all times.
The first LED (closest to the keypad) in the display is an ‘intelligent’ battery status indicator and
will remain on whenever the unit is powered on. The LED will illuminate in one of three colors to
indicate the battery voltage level.
If the LED is green, this indicates that the batteries are fully charged or have sufficient voltage
for normal operation.
If the LED is orange this is an indication that the batteries have enough voltage to operate but,
should be re-charged when the current usage of the unit is complete.
If the LED is red, the batteries should be immediately re-charged to prevent erratic performance
and/or failure of the unit during operation.
True Battery Voltage Indicator
The unit also includes a feature that will allow you to display and see the actual battery voltage
at any time.
To activate the True Battery Voltage test, press and hold the key for at least one second (do
not release the key during the one second period or the unit will shut off). The display will show
1 to 6 LED’s in red, orange, and green to indicate the actual battery voltage as follows:
• 1 red = less than 4.4 volts RECHARGE THE UNIT IMMEDIATELY
• 1 red, 1 orange = 4.4 to 4.6 volts
• 1 red, 1 orange, 1 green = 4.6 to 4.8 volts
• 1 red, 1 orange, 2 green = 4.8 to 5.0 volts
• 1 red, 1 orange, 3 green = 5.0 to 5.2 volts
• 1 red, 1 orange, 4 green = greater than 5.2 volts. Fully charged
OPERATING FEATURES

Automatic Circuit/Reset Feature
The unit features a patented Automatic Circuit and Reset function that set the unit to ignore
ambient concentrations of refrigerant.
Automatic Circuit - Upon initial power on and the completion of the warm-up, the unit automati-
cally 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 the
probe tip after warm-up is completed, and therefore the unit should only be powered on and
allowed to warm-up in fresh air.
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.
Each time the key is pressed (and released), the unit sets its threshold for detection to a level
above the current concentration being detected. By moving closer to a large leak and pressing
each time a full detection is indicated, the user can '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, i.e. sets the
unit to its maximum sensitivity in the chosen sensitivity level.
To reset the unit press the key.
Each time the key is pressed, the LEDs will briefly light in orange to provide a visual confir-
mation of the reset action.
Sensitivity Adjustment
The unit provides two levels of sensitivity. When the unit is switched on, it is set to the high sen-
sitivity position.
1. To change the sensitivity, press the key. When the key is pressed, the LEDs will light in
orange from top to bottom, providing a visual confirmation and indication that the unit is in
Low sensitivity mode.
2. To switch back to High Sensitivity, again press the key. The LEDs will
light in orange from bottom to top, providing a visual confirmation and indication that the unit
is in High sensitivity mode.
7
The base beeping tone is also an indication of sensitivity level.
- In High sensitivity the unit emits two quick beeps approximately once every two (2) seconds, in
fresh air.
- In Low sensitivity the unit emits only one beep, approximately once every two (2) seconds, in
fresh air.
NOTE: In high sensitivity the unit is extremely sensitive to HFC compounds (e.g. R134a),
responding to levels below 0.1 ounces/year (3grams/year). If searching for large leaks of HFC’s,
new azeotrope blend refrigerants (R400 series) or any size HCFC or CFC (e.g. R22 or R12)
leaks, it is best to start your search in Low sensitivity.
Sensor Status Indicator
The unit’s circuit has the ability to automatically diagnose and indicate the sensor’s status.
Whenever the unit is energized, the circuit automatically senses the condition of the sensor and
can detect a failed or missing sensor.
As the sensor ages the circuit will note and indicate this to the user. Initially, an "Old Sensor
Indication" is displayed by flashing the Constant Power Indicator. If this indication appears, you
should immediately obtain a replacement sensor. However, it is not necessary to replace the
sensor before the "Failed Sensor Indication" is received.
If the circuit detects a failed or missing sensor, the 2nd through 6th LEDs will turn red and flash
quickly. The 1st LED will continue to display the battery status as described above. Additionally
the internal pump will be shut down to prevent unnecessary battery drain.
If this indication appears refer to the Maintenance Section on page 13 for service instructions.
Audible / Visual Alarms – Mute feature
The unit features two primary alarm indications – an internal speaker that produces a multiple
frequency tone, and a series of Tri-color LEDs that will provide an incremental indication of leak
detection and proportional leak size.
You may choose to activate both the audible and visual alarms, or solely the visual alarm. Upon
power on, the unit will activate both. If you wish to cancel the audible alarm, or ‘Mute" the unit -
Press the key.
This will mute the internal speaker, and a detection will be indicated solely by the LED display.
Press the key again, at any time, to reactivate the internal speaker.
The LEDs provide a tri-color, proportional indication of leak intensity. The 2nd through 6th LEDs
are used for this indication, while the 1st LED always remains an indication of battery strength.
See figure 5.

When a refrigerant is detected, the visual indicator will light from bottom to top; first in green,
then sequentially in orange, and then sequentially in red. Oftentimes, on anything but the small-
est leak, the extreme sensitivity of the unit may cause the LEDs to all light in orange or red.
As each LED can appear in one of three colors – green, orange or red – this will result in 15
distinct alarm levels.
WARNING: PERSONAL INJURY HAZARD
Do not use this Leak Detector in an explosive or combustible atmosphere. The
ambient atmosphere is drawn through the probe and sensor which operates at a very
high temperature.
The resulting hot mixture of air and combustible gas could explode.
1. Press and release the key to switch the unit on.
2. The LEDs will begin cycling on in orange from bottom to top to indicate warm-up. The warm-
up time is fixed at 20 seconds.
3. After warm-up, all LEDs will flash briefly orange, indicating that the unit is ready for use. The
unit will begin beeping at a steady rate (two quick beeps approximately once every two sec-
onds – indicating high sensitivity) and the first LED will display the battery voltage level as
described in the "Constant Power Indicator" section, above.
4. Choose the sensitivity level in which you wish to start, as described in the "Sensitivity
Adjustment" section, above.
