Tru Pointe COMBUSTIBLE REFRIGERANT GAS WARNING: For your safety, DO NOT use the Tru Pointe refrigerant leak detector to detect refrigerants which are rated as combustible/flammable gases (e.g. ASHRAE - A2 or A3 rated refrigerants). Use with combustible/flammable refrigerant gases can cause an explosion resulting in death or severe injury. WARRANTY Bacharach, Inc.

Tru Pointe Introduction Introduction The Tru Pointe Refrigerant Leak Detector (Figure 1) is a portable, battery powered instrument designed to pinpoint the location of refrigerant leaks in air conditioning and refrigerant systems, chillers, or cold storage units. The use of heated-diode sensor technology allows the instrument to be quickly responsive to all refrigerants, even when high background levels of refrigerant vapors are present.
Tru Pointe Introduction Features • Quickly pinpoints the location of refrigerant leaks • Patented heated-diode sensor that represents the latest advancements in sensor t echnology • Patented microprocessor-controlled circuitry • High and low-sensitivity modes, push button selectable • Automatic zero and background compensation that allows a leak to be quickly found in contaminated atmospheres without requiring manual sensitivity adjustments • Flexible probe 14 inches (356 mm) in length for locating leaks

Tru Pointe Operation Operation Battery Installation 1. Remove battery cover by pressing down on the battery cover tab, and then sliding the cover off the instrument. See Figure 2. 2. Install two ‘D’ alkaline batteries into the battery compartment, observing the polarity markings that are molded inside of the case. 3. Slide the battery cover back onto the instrument until its tab clicks into place. Figure 2.
Tru Pointe Operation Turning the Instrument ON / OFF See Figure 3. The instrument is toggled ON and OFF by pressing the on/off button. When the instrument is first turned ON, observe that the green power on LED will glow, and that the red leak rate LED flashes rapidly along with the audible indicator producing a rapid ticking sound or constant tone. The instrument requires a minimum of 10 seconds to warm up.
Tru Pointe Operation Low Battery Indication A low-battery condition is indicated when the green power on LED begins to flash. Approximately 20 minutes of operation time remains from the time this LED first begins to flash; after which, the instrument’s operation will gradually become erratic. When a low-battery indication occurs, replace the batteries as described under the previous Section Battery Installation.
Tru Pointe Operation When the instrument first detects an increase in the refrigerant level, the leak rate LED begins flashing and the audible indicator begins ticking at a faster rate. If movement of the probe is stopped for more than 10 seconds, the instrument will self-zero and return to its idle state even though refrigerant is still present.
Operation Tru Pointe False Refrigerant Indication False refrigerant indications are usually caused by abnormal changes in sensor temperature. These temperature changes are typically due to a sudden change in air flow past the sensor, or the sensor being heated or cooled by an outside source. To avoid false refrigerant indications, DO NOT . . . • allow the probe tip to become clogged with dirt, • allow the probe to suck in hot gases.
Tru Pointe Operation • Always follow the refrigerant system around in a continuous path so that no areas of potential leaks are missed. If a leak is found, always continue to test the remainder of the system. • At each area checked, the probe shall be moved around the location, at a rate no more than 25 to 50 mm/sec (1 to 2 in./sec), and no more than 5 mm (0.2 inch) from the surface completely around the position. Slower and closer movement of the probe greatly improves the likelihood of finding a leak.
Maintenance Tru Pointe Maintenance By following the procedures outlined below, The Tru Pointe will provide many years of trouble-free and dependable operation. Routine Maintenance • Replace the batteries per Section Battery Installation when the green power on LED begins to flash. • Periodically check the instrument’s sensitivity by exposing it to a source of refrigerant gas.
Tru Pointe Maintenance Sensor Replacement Over time the sensor will become less responsive to refrigerant gas as it nears the end of its useful life. A sensor’s average life expectancy is approximately 150 hours or 1 year of normal use, but will vary depending on the amount of refrigerant that passes through the sensor. Replace the sensor as follows (see Figure 4): Material Required: • Sensor (refer to Section Replacement Parts) Procedure: 1. Turn OFF instrument. 2.
Tru Pointe Troubleshooting Troubleshooting Guide The following table lists the causes and remedies for the most common problems that may occur with the instrument. If the information in Table 1 does not solve the problem, or for help with any problem that is not listed, please contact one of the Bacharach Sales/ Service Centers listed in Section Parts & Service. TABLE 1. TROUBLESHOOTING GUIDE Symptom Instrument does not turn ON. Probable Cause & Remedy a. Batteries are dead or installed backward.
Tru Pointe Troubleshooting TABLE 1. TROUBLESHOOTING GUIDE (Cont.) Symptom Probable Cause & Remedy Short sensor life. Senor has often been exposed to high levels of refrigerant. Avoid exposing sensor to pure refrigerant for long periods of time. Erratic refrigerant leak indication. a. Windy conditions. Shut off surrounding fans; protect probe tip from wind; switch to low-sensitivity mode per Section High/Low Sensitivity Mode. b. Probe assembly loose.
