MECHANICAL DESCRIPTION

sensitivities (High, Medium, Low).

OPERATION

• Press the “ON/OFF” button; this will turn the instrument on and begin the warm-up phase, showing the following screen:

• During the warm-up phase, the center LED of the screen flashes for 30 sec.

• After the warm-up phase is over, the “0” symbol flashes on the screen, indicating that the instrument is ready for use; the buzzer icon is lit,  and the instrument makes a sound every second. You can press the “MUTE” button to mute the buzzer. If the buzzer is already muted, press  the “MUTE” button again to reactivate the buzzer.

• By default, the instrument as soon as it is turned on will perform a sensor autozero, and the autozero icon (A) will be lit red. However, the  autozero function can be disabled by holding down the autozero button “RESET” for at least three seconds; then the instrument will be in  the manual autozero mode. The autozero in manual mode can be done by briefly pressing the “RESET” button; pressing this button for three  seconds will re-enable the autozero mode. When the instrument is restarted, the autozero mode (A) will be restored.

• After the warm-up phase, the sensitivity icon (S) will be red, indicating that the device is at its maximum sensitivity.

• Place the nose of the probe where a leak is most likely to have occurred. If the instrument detects a leak, it will report a leak level on the  display that is proportional to the amount of gas detected and will emit a sound; the greater the leak, the sharper the sound emitted by the  instrument. It is recommended to move the instrument out of the area of the leak for at least 10 seconds before making a new detection pass.

• When the work is finished, press the “OFF/ON” button 3 seconds to turn off the instrument.
  Note: Remove the insulation sheet from the battery compartment before first use.
  CAUTION: Pressing the “SENS” button cycles between three levels of instrument sensitivity (green=minimum, yellow=medium, red=maximum).

4.1 Gas detection method

The figure below exemplifies the method of leak detection:

• Bend the flexible end of the instrument into the shape that best suits the case at hand; slowly move the probe closer to the leakage  point.
• If the instrument detects a leak it will signal this by showing a number from 1 to 7 on the display, where 1 is the minimum concentration  level and 7 is the maximum. At the same time, the instrument will emit a sound to signal the presence of gas, the higher the frequency  the higher the gas concentration.
• Stand back and approach the area of suspected gas leak to confirm that there is indeed a leak at that location.
• When the source of the leak has been found, it is necessary to report it and check the entire system until all leaks have been found an   properly reported.

4.2 Automatic and manual autozero setting

So as to avoid the interference on detection caused by refrigerant in the environment, the detector allows the sensor to automatically  self-zero.
Automatic autozero (Default) : When the A Icon is turned on, the instrument will automatically autozero the room gas concentration  and, only when it detects a higher concentration, it will activate the buzzer. This option is on by default; to diasttivate it and bring the  instrument into manual autozero mode, press the “RESET” button for 3 seconds.
Reset (Autozero) manual: In case the manual mode is on, sensor zeroing can be done by briefly pressing the autozero “RESET” button.
When the screen shows ‘8’, it means that the zeroing has taken place correctly. At this point, a gas concentration higher than the ambient concentration can be detected. To return the instrument to autozero mode, press the “RESET” key for 3 seconds.
Note: If the gas concentration in the environment is very low, the Autozrero function will make the instrument more sensitive, and vice versa, if there is a high gas concentration in the environment, the instrument will be less sensitive.

4.3 Display of instrument sensitivity level
The display constantly shows the sensitivity level of the sensor; this can be set by pressing the ‘SENS’ button and cycling through the  three available levels: High, Medium, Low:

4.4 Leak alarm / acoustic alarm silencing

The detector is equipped with visual and audible signals. If a leak is detected, the instrument displays a number on a scale of 1 to 7  indicating the extent of the leak. The higher  he amount of gas escaping from the leak, the closer the number on the screen will be to 7  and the sharper the audible signal will be. The user can decide whether to keep both signals (visual and audible) active or mute the audible  alarm, keeping only the display indication. After the warm-up phase, the instrument operates normally and automatically activates the  audible alarm; at this point it will be possible to press the “MUTE” button to activate/deactivate the audible alarm.
4.5 Error code summary table

1.  – In case an error occurs in the warm-up phase of the probe, only a service center can repair this fault.
2.  – After solving the problem of the missing or failed probe, the instrument needs to redo the warm-up phase.
3. – When multiple faults occur simultaneously, the order of priority is: 1 E  -> 2 E  -> 3 E

4.6 Automatic shutdown function
The instrument turns off automatically if no button is pressed for at least 30 consecutive minutes. The auto power-off timer is reset every  time the user presses a button on the instrument.
4.7 Battery charge level display
The display constantly shows the state of charge of the batteries via the battery icon, which can take on three colored states described  below.
States of battery charge:

MAINTENANCE

Regular and systematic maintenance can extend the life of the instrument and improve its performance.
Sensor life: can be used normally for up to 1 year. If the sensor is constantly used in environments with high refrigerant gas concentration, the life of the sensor will be shortened quickly. When the life of the sensor is over, the sensor must be replaced.
Sensor replacement : as shown in the figure below, unscrew the probe cap and replace the sensor.
Warning! the sensor and its housing must have good contact.

PRECAUTIONS

1. While you are using the instrument, the pressure of the refrigeration system should be no more than 50psi, and the search area should be  almost draft-free. If there is wind, refrigerant gas escaping from the leak will be quickly dispersed away from the source, thus compromising  gas measurement and detection.
2. The Autozero function is on by default, so when the detector turns on and detects refrigerant gas, it will autozero the with the value of  refrigerant gas in the room at that time. In case Autozero is disabled, you have to press ‘RESET’ button briefly to zero the gas concentration  manually.
3.  The most likely sources of gas leaks are in places polluted with oil or dust and pipe joints. These places should be checked as a priority.
4. The sensor should ideally be kept 3 … 5 mm (1/8 … 1/4 inch) from the suspected leak while searching, so as to preserve the sensor from  environmental pollution that could interfere with the accuracy of the sensor. We recommend moving the probe at a speed to cover 25 … 50  mm per second (1 or 2 inches/second).
5. It is forbidden to bring the sensor into direct contact with an environment with a concentration higher than 30,000 ppm refrigerant gas.
