INTRODUCTION The hilmor Infrared Refrigerant Leak Detector is a hand-held leak detector that uses the infrared detection method. Compared with the traditional leak detector, its sensor has a longer life, higher detection accuracy, greater ease of use, and detects a wider range of refrigerants. The LDIR150 is equipped with a large, easy to read TFT LCD screen.
KEY FEATURES EXTRA CONFIDENCE • Built to last with a 10-year sensor life. EASY TO READ • The TFT LCD screen provides a clear visual confirmation of the leak location. ADDED CONVENIENCE • Audible and visual notification for leak detection. ADDED VERSATILITY • Works on all halogenated refrigerants.
SAFETY SAFETY PRECAUTIONS To prevent personal injury, please read the operating manual carefully and operate only as instructed by following the guidelines listed below. 1. Wear safety glasses, gloves and all other recommended safety gear when working with refrigerants. Contact with refrigerants may cause injury. Please see any warnings associated with refrigerants. 2. Avoid the inhalation of refrigerant. High concentrations of refrigerants are harmful to humans and can cause serious injury. 3.
SAFETY (CONT.) • THE BATTERY HAS BEEN EXPOSED TO LIQUIDS, ESPECIALLY SALTWATER. Exposure to liquids can cause internal corrosion or damage to the cells or to the Battery Management System (BMS). The BMS protects the battery from overcharging, high self- discharge or imbalanced charging of the cells, any of which can present the possibility of fire during recharging. • OPERATING OR CHARGING A BATTERY THAT HAS BEEN DAMAGED FROM DROPPING OR FROM SHIPPING DAMAGE.

FEATURES FUNCTIONS AND FEATURES Please refer to FIG. 1 and FIG. 2 to familiarize yourself with the indicators and keypad controls as you proceed through this section. BATTERY VOLTAGE INDICATOR The Battery Voltage Indicator shows battery level. 4 bars in the battery icon indicate full battery; one bar indicates low battery. SENSITIVITY ADJUSTMENT The unit provides three levels of sensitivity adjustment. When the unit is switched on, it is set to the lowest sensitivity position.
FEATURES (CONT.) BUTTON OPERATION ON/OFF Press and hold for 2 seconds to turn the device “on” and “off”. RESET Reset sensitivity benchmark to improve stability and sensitivity. MUTE Press to toggle the audible alarm “on” and “off”. SENS Press button to cycle through three levels of sensitivity, low, medium, and high. PEAK Press to turn peak function “on” and “off”. The maximum value is cleared when turned off. BATTERY CHARGING INSTRUCTIONS 1.
OPERATING INSTRUCTIONS This unit detects relative concentrations of refrigerant, the sensor tip must always be in motion. Keep the unit away from moisture and high voltages. To detect leakage in a refrigeration system, the system must operate at a minimum of 50 PSI. Environmental temperatures lower than 59°F (15°C) may further reduce a system’s operating pressure, causing a leak to become more difficult to detect. In such cases, “No Leak” may be falsely indicated, requiring an alternate diagnostic means.
TECHNICAL SPECIFICATIONS Sensor Type: Infrared Spectrum Absorbtion Sensor Life: 10 Years (Typical) Maximum Sensitivity: 4 grams/year Response Time: ~3 seconds Warm-Up Time: ~30 seconds Operating Environment: 32°F (0°C) ~ 104°F (40°CF ) at < 75% RH (non-condensing) Display Method: TFT LCD display Notification Mode: TFT LCD display and audio Battery: Built in rechargeable lithium battery: 3.
