general description Thank you for purchasing the TIFZX Heated Pentode™ Refrigerant Leak Detector. We are proud to offer what we believe is the very best portable electronic leak detector available today. TIFZX offers the greatest sensitivity and fastest response of any portable refrigerant detector available. This is achieved through the employment of a Heated Pentode™ sensor combined with a sophisticated microprocessor-controlled circuit.

getting started WARNING: To prevent personal injury, do not use this Leak Detector in an explosive or combustible atmosphere. Ambient atmosphere is drawn through the probe and sensor, which operate at a very high temperature. The resulting hot mixture of air and combustible gas could explode. Unpacking Unpack the unit from the carton and carrying pouch. Refer to the Parts and Controls section for parts identification.
Once the battery pack has been installed, plug the battery charger into a wall outlet and connect the charger jack to the unit (see Fig. 3). When correctly connected, the first LED will indicate charging status: Quickly flashing orange = battery charging Slowly flashing green = battery fully charged Slowly flashing red = failed batteries; cannot be recharged Fig. 3 New or completely discharged batteries will take approximately two (2) hours to fully recharge.
operating features This unit includes operating features designed to increase usability and simplify user interface. Please refer to the Parts and Controls diagram on page 3 to familiarize yourself with the indicators and keypad controls as you proceed through this section. Constant Power Indication The Constant Power indicator allows the user to see the battery level at all times.
Automatic Circuit/Reset Feature The unit features Automatic Circuit and Reset functions that set the unit to ignore ambient concentrations of refrigerant. Automatic Circuit - Upon initial power-on and completion of the warm-up, the unit automatically sets itself to ignore the level of refrigerant present at the tip. Only a level, or concentration, greater than this level will cause an alarm.
The standard beeping tone is also an indication of sensitivity level. - In High sensitivity the unit emits two quick beeps approximately once every two (2) seconds, in fresh air. - In Low sensitivity the unit emits only one beep, approximately once every two (2) seconds, in fresh air. Sensor Status Indicator The unit’s circuit has the ability to automatically diagnose and indicate the sensor’s status.
Constant Power Indicator (1st LED) Proportional indicators (2nd – 6th LEDs) Figure 5 When a refrigerant is detected, the visual indicator lights from left to right; first in green, then sequentially in orange, and then sequentially in red. Often, on anything but the smallest leak, the extreme sensitivity of the unit may cause the LEDs to all light in orange or red. Since each LED can appear in one of three colors – green, orange or red – this will result in 15 distinct alarm levels.
5. Begin searching for leaks. Move the probe tip toward the suspected leak. The flexible probe may be shaped to provide access to hard-to-reach areas. NOTE: If the unit has previously been in service, verify the probe tip is not obstructed with dirt, grease, etc., and check the condition of the filter as described in the Maintenance section. 6. If a refrigerant is detected, the unit will begin to alarm – the audible tone will quicken and the LEDs will light.
4. In windy areas, even a large leak can be difficult to find. Under these conditions, it is best to shield the potential leak area from wind or breezes. 5. A leak is a constant source of refrigerant, and when a true leak source is located, it should produce a repeatable alarm each time it is approached. Intermittent (nonrepeatable) alarms are often caused by accumulations of refrigerant near or around leak points. 6.
6. Verify an apparent leak as follows: a) Blow shop air into the area of the suspected leak. Repeat the check of the area. In cases of very large leaks, blowing out the area with shop air often helps locate the exact position of the leak. b) Move the probe to fresh air and reset. Then hold the probe tip as close as possible to the indicated leak source, and slowly move around it until the leak is confirmed. Automotive A/C Systems Only 7.
2. When correctly connected, the first LED indicates the charging status: - Quickly flashing orange = battery charging - Slowly flashing green = battery fully charged - Slowly flashing red = batteries failed; cannot be recharged New or completely discharged batteries take approximately two (2) hours to fully recharge. 3. When the LED indicates the batteries are fully charged (slowly flashing green), the unit is ready for operation.
As described in the Operating Features section, the unit’s circuit automatically diagnoses and indicates the sensor’s status. If an Old Sensor Indication is received, obtain a new sensor as soon as possible. Refer to the Replacement Parts section . If a Failed (or missing) Sensor Indication is received: 1. Remove the flexible probe by firmly grasping it and rotating it counterclockwise. This exposes the sensor in the end of the unit (see Fig. 7). Verify the sensor is installed. A.
Threaded Bushing Fig. 8 Pins Sensor 6. Install the flexible probe by threading it clockwise onto the threaded brass bushing around the sensor until it is finger tight. CAUTION: To prevent personal injury and equipment damage, NEVER operate the unit without the flexible probe correctly installed. Sensor contamination, erratic performance, and other problems may occur. Additionally, the sensor will become quite hot during operation, which could be dangerous.
Filter Cartridge and Tip Installation Instructions 1. Remove existing tip and old filter. Replace existing o-rings, if damaged. 2. Verify probe is clean. Use dry shop air to blow out both ends of the probe, if possible. 3. Install new filter cartridge to the probe with pointed ends of the raised ribs oriented toward the tip. See Figure 9. 4. Thread the new tip onto the filter cartridge. The filter cartridge should be snug against both o-rings.
