Leak Detector effect. Frequently charging routine after use is recommended to avoid over discharging which could damage the battery. 6-3 Lithium Battery Care The Refrigerant Leak Detector contains a very powerful Lithium-ion battery. For a long battery life and safe operation, you must observe the following: CAUTION! (1) Do not short-circuit battery. - Page 10 Leak Detector Fig.1 6-4 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.
- Page 11 Leak Detector Ambient Reset Feature - Resetting the unit during operation performs a similar function it programs the circuit to ignore the level of CO 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.
- Page 12 Leak Detector When the unit is switched on, it is set to the Medium sensitivity level. To change the sensitivity, press the “L/M/H” key. Sequentially Indicate: H→L→M→H When switching to High sensitivity, the all LED's (2 green+2 orange+3 red) will momentarily light. ...

Leak Detector 7. OPERATING PROCEDURE 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 air flow over the sensor and cause the instrument to alarm. - Page 14 Leak Detector audible tone will alarm. Additionally, the visual indicators will light from lower to higher; green LED then orange then (highest concentration) as increasing of level indicate 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.
- Page 15 Leak Detector with the CO refrigerant in the air. Use the following “double pass” procedure to find leaks by detecting the change in CO refrigerant concentration. (A)Charge system with sufficient refrigerant. Turn the system on and force compressor to operate. This could set the high pressure end of the circulation ring to its operating pressure.
- Page 16 Leak Detector (D)Recheck service valves with caps removed. Air clean the service valve to clear the immediate area, and then check with detector with medium sensitivity setting. (E)Move the detector at the speed no more than 75 mm/sec (3 in/sec) and as close as possible to 6 mm (1/4 in) from the surface, completely encircling each test position (switch, sensor, refrigerant tubing connection, etc).

Leak Detector amount of contaminant. It will typically clear in 2 to 15 seconds. When the source of the leak is detected, the detector may cause a reaction. If the first green LED continues to flash, indicating that the sensor is not restored to the best condition. - Page 18 CENTER TECHNOLOGY CORP. 4F, NO.415, Jung-Jeng Rd., Shu-Lin Dist., New Taipei City 238, Taiwan TEL : 886-2-26763926 E-Mail : center@centertek.com FAX : 886-2-26763925 http : / / www.centertek.com GCA000389-02000...
