Product Description
1, LS790B portable SF6 Leak Detector overview of qualitative
For many professional leak detection requirements, the quick and accurate to identify
refrigerant leak is very critical. LS790B is the professional design of very effective
detection of all CFC, HFC, HCFC refrigerants and mixed refrigerants.
LS790B to maintain a strong multi-faceted applicability. Even today, the new refrigerant
such as R410A, R404, R407, R406 and so on. 10 adjustable sensitivity settings and sensor
circuit patented technology guaranteed to find any effective refrigerant leak of any size.
LS790B is light and easy to carry features. Expected to allow users to directly detect any
leakage in the area, not too far away or there is a limit to consider the place. It looks
to provide a comfortable grip capital, metal hose can be bent towards any direction.
LS790B leak detectors to advanced micro-processing circuit with user friendly features
combine to achieve the best leak detection. Design uses the most advanced sensors to detect
corona discharge all of the halogen gas with unmatched stability, reliability and
consistency. Instrument sensitivity setting of 10, more than 100 kinds of tones and 10
lights. LS790B leak even under severe background contamination can detect the smallest 7 g
/ year leakage. LS790B leak detectors to advanced micro-processing circuit with user
friendly features combine to achieve the best leak detection. Design uses the most advanced
sensors to detect corona discharge all of the halogen gas with unmatched stability,
reliability and consistency. Instrument sensitivity setting of 10, more than 100 kinds of
tones and 10 lights. LS790B leak even under severe background contamination can detect the
smallest 7 g / year leakage.
Features:
Variable sensitivity: only 10 range and sensitivity can detect all halogen gas leakage
instruments. At the lowest sensitivity settings, LS790B HFC-134a can detect the leakage
rate to 15 g / year; at the highest sensitivity settings, HFC-134a can detect the leakage
rate to 7 grams / year.

Procedures:
Note: In the air conditioning system, the test must be off the engine.
1, air-conditioning system or refrigeration system should have enough refrigerant gauge
pressure of at least 340kpa/50psi, while the system is turned off, the temperature is lower
than 15 ℃, pressure to reach this number of leak may not be detected.
2, careful not to stain the probe part of the metal hose, high concentration of refrigerant
in the environment, if the probe is particularly dirty or there is water, should take a
clean soft paper wipe or blow the air cleaner power plant. Taboo, do not use detergent or
solvent cleaning leak detectors, leak detectors with them to avoid adverse reflection of
unnecessary equipment damage.
3, detection of leaks throughout the system as follows: in all pipeline, hose and air
conditioning system parts to find traces of oil lubricants, damage and connected place,
with the leak probe to look carefully place each questionable, such as : All the joints,
hose and copper tube junction, each control parts of the maintenance points with a hat,
welding parts and so on.
4, testing should be continuous along the pipeline, so to ensure that no areas are missed.
If a leak is found, other parts of the system to continue testing to confirm whether there
are leaks.
5, and then test each region, the probe should be around the leak point, and not more than
25-50 mm / s movement, while the surface position detection rate does not exceed 5 mm / sec
slowly moving toward a possible leak probe region to find.
6, an obvious leak, such as is found, it is best to use high-pressure air to blow a leak.
If necessary, repeat the test in this place.
7, check the copper evaporator leaks, will need to open air and open to the highest, run 15
seconds. Turn off air conditioning and 10 minutes to reach all of the refrigerant piping.
Then the leak probe into protective cover or condensate discharge device within the
Department, to confirm that there is no water, such as leak detectors, alarms, leak
detection and refrigerant leak detection system maintenance points are essential. 8, to
comply with any refrigeration repair, damage and other cooling system maintenance, leak
detection and refrigerant leak detection system maintenance points are essential.
4, operation skills:
1, the wind environment: Do not test the wind environment leak, even if is a big leak can
not be detected, because the gas will leak out quickly into the atmosphere, so that you can
not be detected. If possible with lead foil to produce a gas mask on the joint or joints,
or to move without detection area to detect the wind environment.
2 sensitivity settings: MAC proposal to set the level of leak test 5-6, the best
sensitivity is set to 1, this allows variable output alarm. Visible light running within 10
light box, but not all of the instructions alarm. Note: Select high sensitivity to the
highest audible tone continuous tweet or all of the 10 consecutive light flashes, you need
to transferred to a lower sensitivity settings, try again.
3, selective filters: there is again a regional moisture leak detection leak detection
equipment will result in false alarms, when looking for leaks or other high humidity
evaporator capacity around the region when there has patented a selective dry filter. There
can be removed from the water caused the alarm.
5, leak confirmed:
If a leak is detected again after moving probe experiments, get the same leak alarm, you
can confirm the leak.
When to use PIN-POTNT key:
If there is a large area of the leak, the leak around the region will form a refrigerant
surrounding area, which is the source of leakage of refrigerant around the attack, so that
leakage is not easy to confirm, then will need to set the PIN-POINT key to solving these
problems . Click PIN-POINT button, start looking for leaks region, when the detected leak
will be automatically saved when the LS790B detect refrigerant concentration levels, the
highest concentration of the probe to find the level of refrigerant region, a bipolar alarm
began to alarm, allowing you to quickly find leaks source.
6, maintain:
LS790B air leak detector maintenance is relatively simple. Just a regular cleaning probe,
ion pump sensor and battery replacement.
1, low-voltage Tip: When you open the device, the LCD screen kept flashing the middle of
that battery power is low, you can replace the four AA batteries.
Note: Do not use rechargeable batteries.
2, replace the ion pump sensors: ion pump sensors require regular replacement, if the
instrument is indicated at the lowest sensitivity is not normal or when the false alarms,
requiring replacement of the ion pump sensor. Operation as follows:
First turn off the switch, to be replaced. This instrument is equipped with a new random
ion pump sensor.
3, with patented selective filters: the probe must be confirmed through the air is clean
pollution-free, non-blocking and is smooth. Remove the probe from the metal hose also
removed when the ion pump sensor (Note: must be shut down). Try to use low pressure air
blows off the dirty filter (do not try other means). If you still can not clean, we must
replace the new filter.
