0 Interstitial Liquid Sensor Installation Guide Safety Wamings Safety Warnings Equipment Preparation To prepare your equipment for sensor installation: 1. Turn Off power to the console. 2. Make sure no liquid is present in the annular space. Do not install the sensor if any liquid is present in the annular space. Failure to comply will lead to an alarm. 3. To ensure the sensor will reach the bottom of the annular space, the splice between the leader cable and the sensor must be 1 foot from the bottom of the riser pipe (Figure 1). a. First measure the sensor riser pipe from the bottom of the pipe to the top. b. Subtract 1 foot from the riser pipe measurement, c. Measure the distance up the leader cable from its connection to the sensor; mark the leader cable with a piece of tape. Installation of Float Switch To ensure proper operation of the float switch, it is important that you install a sensor with the correct cable length. This ensures the float switch will rest as close as possible to the bottom of the tank annulus (Figure 1). This device is installed in equipment where potentially lethal voltages may exist and where product spillage could create serious environmental and safety hazards. .; • The following hazards exist: 1. Electrical shock resulting in serious injury or death may result if power is on during installation and the device is improperly installed. 2. Product leakage could cause severe environmental damage or explosion resulting in death, serious personal injury, property loss and equipment damage, Observe the following precautions: 1. Read and follow all instructions in this manual, including all safety warnings. 2. Comply with all applicable codes including: the National Electrical Code; federal, state, and local codes; and other applicable safety codes. 3. Before installing this device, turn Off power to the system, including console and submersible pumps. 4. Substitution of components may impair intrinsic safety.
