  • Page 6 WARNINGS Inhalation of high concentrations of refrigerant vapor can block oxygen to the brain causing injury or death. Do not use this device in a combustible gas atmosphere or with A3 refrigerants such as R-290, propane or R-600, isobutane. Do not block exhaust port or device or will not function properly.
  • Page 7: Quick Start

    1. Install sensor (see next panel for details). 2. Move to a refrigerant-free environment and hold until your DR58 powers on. 3. Allow warm-up (calibration) to complete. Total used sensor hours is also displayed. 4. Begin searching for the leak source.
  • Page 8: Sensor Installation

    Sensor Installation 1. Ensure your DR58 is powered off. 2. Remove the 3 screws of the sensor cap. 3. Pull the sensor cap away from the back case. 4. If replacing, pull out the old sensor. 5. Push new sensor (RHD1) into pin holes. Pin orientation does not matter.
  • Page 9: Maintenance

    Maintenance CLEANING: Clean the exterior with a damp cloth. Do not use detergents or solvents. BATTERY CHARGING: Recharge the internal battery as needed using the USB-C cable. In addition to the AC plug, most generic USB ports supply enough power to charge. The long life Li-ion rechargable battery is permanently installed.

    3. With DR58 set to high sensitivity (H), remove the cap and wave the tip over the cap. You should see a very large leak size of approxi- mately "99" and a full bar graph. If not, the...
  • Page 11: Operation

    Press to toggle the blue backlight. Zero Modes (AZERO/MZERO) DR58 starts up in automatic zero mode (AZERO) which sets a new zero point every two seconds, indicated by AZERO blinking twice. Moving closer to the leak source will show the relative increase in concentration, triggering the alarm.

  • Page 13: Maximum Mode

    The recorded max is cleared when the sensitivity is changed or if manually zeroed. Sensitivity (H/M/L) DR58 starts up in high sensitivity (H) which is recommended for most situations. When leaks are difficult to pinpoint due to excess triggering or sensor saturation, press SENSITIVITY to cycle to a lower sensitivity (Medium/Low).
  • Page 14 Red Leak Indicator LED In most situations, the red LED at the tip is easier to monitor than the display. Because the blink rate increases as the relative concentration increases, many leaks can be found without ever viewing the display. LEAK SOURCE...
