Before activating the probe attach the grounding clip to a suitable earth ground To verify that the unit is operational press the test button on the face plate If the power is ON the visual audible alarm will be activated A low battery condition will cause the Low Battery indicator to be illuminated BEFORE REPLACING BATTERIES READ SECTION ON INTRINSIC SAFETY AND APPROVAL To release the probe pull the protector tube outward from the reel casing To lower the probe tilt the front of the reel housing forward and press the brake release The brake release is located just forward of the handle The tape will reel out as long as the brake release is pressed Lower the probe into the well taking care not to allow the probe or tape to rub against the well casing Refer to Appendix B for an alternative means of probe deployment When the probe contacts liquid the visual audible alarm on the reel will be activated An oscillating alarm indicates water a continuous alarm indicates hydrocarbon To determine the exact thickness of a hydrocarbon layer the probe should be slowly lowered to the air hydrocarbon interface until the alarm is activated With the probe at the exact point where the alarm comes on read the numbers on the tape to determine the distance from the top of the well head to the air hydrocarbon interface Face Plate Removed Battery Pack Retaining Clip Batteries Switch Electronics Housing Battery Pac
6. If the probe has not sensed liquid within 4 minutes from the time power is applied the unit will automatically switch to a low power mode This prevents battery drain in the event the power is left on accidentally To restore power place the handle in the OFF position and then back to the ON position Chapter 4 System Maintenance The ORS Interface Probe is designed to be virtually maintenance free only maintenance required is cleaning off the reel and probe and periodic replacement of the batteries After every measurement the probe should be washed in Alconox detergent rinsed in distilled water washed again in Alconox and rinsed for a final time in distilled water Also clean all accessible parts of the reel assembly Under some circumstances a more aggressive cleaner may be required to prevent cross contamination of wells Before replacing the batteries read section on intrinsic safety and approval 10 Chapter 5 System Troubleshooting The ORS Interface Probe is a sealed unit and is not easily repaired in the field With the exception of replacing a damaged prism any major malfunction should be referred to the Customer Service Department at Geotech Environmental Equipment Inc 800 833 7958 or 303 320 4764 To remove a damaged prism use a 19 mm wrench hex socket 6 point and unthread the prism assembly from the probe bottom A replacement prism assembly is available by ordering Part Number 2060010
