****** Page 1 ****** CLD-IOO HALOGEN LEAK DETECTOR Instruction manual General Information Elitech 1 General Information 2 Incorporated with advanced leak detection technology, CLD-IOO is an ideal and economic halogen leak detector-Compact in appearance, it is stable and easy to operate. Detect all kinds of halogen refrigerants Sensitivity can be adjusted at any time and the detector can be adjusted automatically to the best state of detection. Inner precise IC with ultra-low circuit consumption offers more stable functlon and lengthens battery life. Two-color visual display of battery voltage. Excellent sensor brings high sensitivity and longer service time. Operating temperature: Maximum sensitivlty: Battery life: Response time: Work mode: Fixed probe length: Dimensions: Warm-up time: Reset time: Power supply: Detection Range OOCto 520C(30’F to 125T) 6 grfyr, for all halogenated refrigerants approximately 20 hours in normal use, nstantaneous, continuous, no limitation. 20cm. 22.9cm x 6.5cm x 6.5cm. approximately 6 seconds. 2-10 seconds. 6V DC, four AAA excellent batteries. The CLD-IOO may also be used to detect leaks in other systems and storage/recovery containers,lt will respond to all halogenated (includ ing Chlorine and Fluorine) refrigerants. This includes but not limited to: CFCs etc. HCFCs etc, HFCs etc. Blends such as AZ-50, HP62, MP39 etc- • Detect Ethylene Oxide gas leaks in hospital sterilizing equipment (it will detect the halogenated carrier gas). Detect SF-6 in high voltage circuit breakers. Detect most gases that contain chlorine, Fluorine and Bromine(ha logen gases), • Detect cleaning agents used in dry cleaning applications such as perchloroethylene. • Detect halogen gases in fire-extinguishing system. Battery Indicator The forepart light of panel indicates the leak and the battery voltage. GREEN Battery voltage is normal, sufficient for proper operation. ORANGE Battery voltage is approaching the lower threshold for operation. Replace them as soon as possible.

If a leak is found, always continue test the remainder of the system •At each area checked, the probe should be moved around the location, at a rate no more than 25 to 50mm/second(1-2in/second). And no more than mm(1/4inj from the surface, completely around the position. Slower and closer movement of the probe greatly improves the likelihcod of finding a leak. • An apparent leak shall be verified at least once as follows: Blow shop air into the area of the suspected leak, if necessary,and repeat a. checking the area. In case of very large leaks, blowing out the area with shop air often helps locate the exact position of the leak. b, first move the probe to fresh air and reset- Then hold the probe tip as dose as possible to the indicated leak source and sbwly move around it until the leak is confrmed- • Automotive AJC systems only Leak testing of evag:xyator core v,hile in the air conditioning module shall accxynplished by tuning the air (Dnditioning fan on high level for a perbd Of 15 seconds in münum, shuting it off, then fu tlT refrigerant to acumulate for I O mnutes-After such time, insert the probe into the fan resistor block or condensate drain hole, if no water is present, or into the closet opening in the b,eætingtventl atbn/air cmdlboning to the evaporator, such as the heater duct or ventduct. Ifthe detector alarms, a leak apparenty has been found. Notesi • Shut down the engine during detecting automotive AJC systems leak. Following any to the refrigerant systems and any Other vdlich disturbs the refngerant system, a leak test Of the repair and Of the service of the refrigerant system should be done, Maintenance 6 • Switch the detector on and buzzer will beep discontinuously, • Verify the battery voltage level by observing the power indicator. • Adjust appropriate sensitivity, or adjust the sensitivity at any time during operation, This adjustment will not interrupt detection, • To detect leak when the detector is switched on for 6s. When refrigerant leak is detected, the buzzer will change to a “sire” type sound • Verify the place where siren sounds and detect continuously until the leak is located. Notes: CLO•100 features on automatic circuit and a reset function that enables it to ignore ambient concentrations of Halogen upon initial power on, the detector automatically sets itself to ignore the level of refrigerant present at the tip in 6s and enter into the best state of detect.on, If place the sensing tip near a known leak source and switch the detector on. it is convement to find higher concentration leak. Or move the detector to fresh air and switch it on ,adjust it to maximum sensitivity, any concentration above zero will be detected, In measuring state, automatic circuit will follow the change of halogen gas concentration in environment to avoid false alarm, The detector vari-speed sensitivity adjustment and can be adjusted in the course Of detection. Adjust the faucet clockwige/counterclockwise for high/law sensitivity. It does not mean the higher sensffvity is adjusted ithe better the detector will work,because if the is not fresh. selecting higher sensitivity will cause an improper alarm. When the leaked gas is detected, the audible tone will change to a-sven” type sound ,More refrigerant, more siren-At the same time, indicator light ig flashing quickly. Operating Tips • Adjust to higher sensitivity when a leak can’t be found. Adjust to lower sensitivity when the detector runs unstably. • When the buzzer alarms for leak,if the sensing tip remained at the part being detected long enough ithe circuit will equalize it. • In windy areas, even a large leak is difficult to be found. Under this condition it is better to shield the potential leak area. • Be aware that the detector may alarm if the sensing tip contacts with moisture and/or solvents. Therefore, avoid contact with these during leak checking. Appropriate maintenance ofyour leak detector is very important. Carefully following the instructions to reduce the mal-operation and prolong the life expectancy of the detector. Keep the sensmg up dean front the dust, moisture and grease, If the tip itself is didy it can be cleaned by immerSing in a mild solvent, such as alcohol, for several seconds, and then using co sed air and/or a towel to clean. • Never use solvents such as gasolinemæentine, minerals etc, They will leave detectable residue and desensitize your detectcr, Warning Turn the detector off before replacing the sensing tip, Failure to do so may result in a mild electric shock! Sensing tip replacement The tip Will eventually wear out and require It is difficult to gredict exacüy when this vdl occur Since tip bngevity is directy related to conditions and frequency of use. The tip should replaced whenever the alarm sounds or bemmes erratic in a clean and pure environment. • Take out the batteries in case the detector is left unused in long term, If detector does WOIk, please check whether the batteries are in a stable or the ‘sechage is acmptable If rot #ase inspect whether the tip is dlr%or in a stable tnnnection with Your part Of openmg e detector is beyond the warranty
