Rend iser Pipe cap onduit m <br /> Fining Conduit <br /> Panel <br /> The model DF reservoir sensor includes a high level and low level <br /> float switch for liquid level sensing in the tank-mounted reservoir. Riser Pipe <br /> The reservoir sensor is placed into the tank-mounted reservoir <br /> located at the top of all model DW7-2P and DWT-4P double-wall Resoir sanso <br /> tanks.After the cavity between the inner and outer tank and the ery <br /> (Moa"of <br /> reservoir have.been filled with water or antifreeze',the reservoir <br /> sensor is positioned through a 4"diameter riser pipe.When the FRP Re enoa High Level Alarm <br /> reservoir liquid level is adjusted to two-thirds full,the sensor will Low Larval Alarm <br /> operate in the normal mode. <br /> An inner wall tank leak will always result in liquid draining from the Couble Wall Tank <br /> reservoir,which will activate the low level alarm.An outer wall leak <br /> in a high groundwater condition will cause the liquid level in the <br /> reservoir to activate the high level alarm. <br /> The model DF reservoir sensors are only compatible with the 1.3 Specifications <br /> Veeder Root,MSA and Red Jacket control panels.The reservoir Reservoir sensor(model DF) <br /> sensor is not compatible with the control panels supplied by O/C <br /> Tanks(models S80011 B and SB001413).
