C5. Fiberglass Reservoir Sensor (con't) <br />For RS -10 Reservoir Sensors: <br />• Pipe fitting connections provide quick, easy access to <br />sensor and reservoir without disconnecting any electri- <br />cal or piping connections. <br />• Sensor includes riser pipe cap with a length of flexible <br />conduit which is connected to a NEMA 4 or NEMA 6 <br />electrical junction box (contractor supplied). <br />• PVC riser pipe cap slips on and off the PVC fitting in- <br />stalled on top of riser pipe. <br />Fiberglass Reservoir Normal Installation Detail <br />/ Concrete Tratfic pad <br />Riser Pipe Cap <br />P, -Box <br />and Fitts g' <br />Conduit to <br />Riser Pipe Control Panel <br />Reservoir Sensor <br />High level Alarm <br />FRP Reservoir <br />Low level Alarm <br />Double -Walt Tank <br />'Ensure four 1/8' or t/4' holes for vent <br />For Extreme High Groundwater Conditions <br />• In order to prevent the intrusion of groundwater in the <br />reservoir: <br />❑ Plug the factory drilled vent holes (4) in PVC riser cap. <br />❑ Install a separate vent line from riser pipe to above <br />ground. <br />❑ Glue the PVC riser pipe to riser pipe fitting. <br />Fiberglass Reservoir Installation Detail <br />for Extreme High Water Conditions F <br />Concrete Traffic pad <br />Reservoir ZI <br />to Grade <br />FRP R <br />Double-Wall Tank <br />Optional RM Reservoir Monitor: <br />• Optional sensor requires no electrical power source. <br />• Sensor includes riser pipe cap with electronics and bat- <br />tery pack. <br />• Riser pipe cap slips on and off PVC fitting which is <br />installed on top of contractor supplied riser pipe. <br />• The internal, replaceable power source is a battery with a <br />5 -year estimated life. This should be tested periodically. <br />• To test, simply push button on top of cap. Light shows <br />green for liquid in reservoir, red for no liquid in reser- <br />voir. No fight indicates loss of battery power. <br />t6 <br />C6. Electrical <br />AWARNING <br />• Do not place intrinsically safe sensor wiring in the same <br />conduit as non -intrinsically safe wiring. <br />DO <br />• Make certain all electrical work conforms to local codes. <br />• Wire reservoir sensor to the control panel using wiring <br />specified on control panel wiring diagram. <br />CAUTION: Place wiring in water tight conduit and junc- <br />tion boxes (to maintain leak detection capability). <br />C7. Testing <br />To simulate low liquid level condition: <br />• Remove sensor from fiberglass reservoir. <br />To activate low level alarm: <br />• Remove sensor from fluid in reservoir. <br />To activate high level alarm: <br />• Fully immerse sensor into a bucket of water. <br />C8. Reservoir Leak Detection <br />What to do for an alarm condition: <br />• Remove the riser cap. <br />• Extract reservoir sensor. <br />• Use dipstick to measure reservoir liquid level: <br />❑ If dipstick measurement is 1.25" (2" for tanks 15,000 <br />gallon capacity or larger) or less, reservoir has <br />drained, indicating a low level alarm. <br />❑ If dipstick measurement is 14" or higher, the high <br />level alarm has been activated. <br />For a Low Level Alarm: <br />• Refill the reservoir to `/2 full. <br />• Continue monitoring. <br />For a High Level Alarm: <br />• Remove liquid from reservoir until it is %2 full. <br />• Continue monitoring. <br />If alarm occurs and reservoir level is normal: <br />• Consult your local electrician. <br />❑ Control panel is improperly wired or has a defec- <br />tive component. <br />• See section D9 on Control Panel False Alarms. <br />Important: If a second low level or high level alarm <br />occurs, call Fluid Containment Field Service.
