L If the delivery is not stopped and the liquid rises to about 98%of tank capacity,the bypass valve closes completely.No additional liquid can flow into the tank until the level drops below a reset point. Models of the 6180 are available to meet virtually any UST application including two-point, coaxial,poppeted coaxial and remote fill.The 6180-3000 provides two-point overfill protection for _ 3"riser pipes,and the 61SO-1000 and 6150-1000(CARE)feature a grooved-tube design for use with tank gauging systems.Methanol and GARB(vapor-tight)approved models are also available. The OPW 61 SO is approved by the New York City Fire Department.(Approval#4902) a i IMPORTANT In order to prevent product spillage from the Underground Storage Tank(UST),properly maintained delivery equipment and a proper correction at the tight-fill adaptor are essential.Delivery personnel should be managed and trained to inspect delivery elbows and hoses for damaged and missing parts.They should always make certain there is a positive connection between the adaptor and elbow.If delivery equipment is not property maintained,or the elbow is not securely coupled to the adaptor,a serious spill may result when the OPW 6150 closes,causing a hazard and environmental contamination. NOTE: The OPW 61 SO is designed for use on tight-fill gravity drop applications only. Do not use for pressure fill applications.
