Commissioning
Installing Batteries:
- Loose the screw and remove the battery compartment cover located on the bottom of the unit.
- Install 4 “AA” size alkaline batteries.
- Reinstall the battery cover by aligning it with the handle.
When the batterie-durability is reached, a red LED illuminates to indicate low battery. The batteries should be replaced as quickly as possible.
Automatic Ambient Reset Feature:
This Refrigerant leak detector features an Automatic Ambient Reset function
that sets the unit to ignore ambient concentrations of refrigerant.
-
Automatic Ambient Setup – Upon initial power on, the unit automatically sets itself to ignore the level of refrigerant present at the tip. Only a level or con-centration, 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! -
Ambient 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.
-
After the unit is warmed up, the default sensitivity level is set to “High” and the Auto Reset function is “ON”.
-
Auto Reset function is best used initially when the user is moving around trying to identify the leakage source. Once the leak source is determined, cancel the Auto Detect function to proceed with leakage measure-ment.
-
Auto Reset function should be turned OFF when use in fixed position leakage detection.
Feature Sensitivity Adjustment:
The Instrument provides three levels of sensitivity. When the unit is switched
on, it is set to a high sensitivity level.
- To change the sensitivity, press the Sensitivity key. When the key is pressed, the visual display will momentarily show the two left LEDs (green) indicating a Low Sensitivity level is selected.
- To switch back to High Sensitivity, press the key.
The two right LEDs (red) will light momentarily indicating high Sensitivity
level is selected.
Operation
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 airflow over the sensor and cause the instrument to alarm.
Power-Up key:
The ONOFF key turns the Refrigerant leak detector instrument ON or OFF
function.
- Press it once to turn on the Refrigerant leak detector, the display will illuminate with flash, for 45 seconds to eat up the sensor. After this period the unit can be used.
Auto reset & Reset function key:
When the Auto Reset function is turned ON, the meter will monitor the
background status and fine-tune itself. When the Reset LED light is on, it
indicates it is in ON mode.
-
Press Reset button and hold for 2 seconds the Reset light will turn off and the Auto Reset function is in OFF mode.
When the Reset light is off, it indicates the Reset function is in manual mode. -
Press the Reset button once to enable the manual Reset function.
Verify the condition of the unit and sensor:
- Set the sensitivity level to “Hi”.
- Open the leak check bottle cover and slowly move it closer to the snake tube nozzle.
If the indicator moves up to high from low then we should move the check
bottle away and the LED should go off again. This shows that the unit is under
working condition.
If the unit does not perform as we expect, bring the unit for maintenance at
your local sales office.
Enter the measuring mode:
- 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 (6 mm) of the possible leak source.
- Slowly move the probe past each possible leakage point.
- When the instrument detects a leak source, the audible tone will alarm. Additionally, the visual indicators will light from left to right, Green LED then Orange LED then Red LED (highest concentration) as an increase in level indicates that the location is close to the source.
- When the Instrument signals a leakage, 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.
- Return the sensitivity switch to HIGH before searching for additional leaks.
- When you‘ve finished leak testing, turn OFF the instrument and store it in a clean place, protecting the leak detector from possible damage.
Replacing new sensor
The sensor has a limited operative period. Under normal operation, the sensor should work for more than one year. Exposing the sensor to a high density of refrigerant (>30000ppm) will shorten its life cycle rapidly. It is important to ensure that the sensor surface is free from water droplets, vapor, oil, grease, dust, and any or all other forms of contaminant. Furthermore, to ensure the good working condition of the unit, sensors must be replaced periodically when their operative life is over.
WARNING! When replacing new sensor, the worn-out sensor may be HOT!
- Remove cone cap cover from the tip of snake tube.
- Pull out old sensor and insert the new sensor into the plug.
- Seal the cap cover over the plug.
Cleaning
The Instrument’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. Gasoline and other solvents may damage the plastic and should be avoided.
WARNING! The detergent or isopropyl alcohol might damage the sensor, please keep them from the sensor throughout the process.
