All length measurements are in inches. Please contact the Authority Having Jurisdlc- <br /> Non(ANA and review local,state,and national codes to determine the regulatory requirements governing <br /> shut-off capacity in your region,as well as take into account other considerations such as extreme tank tilt. <br /> Tank ID: T2: Premium(PUL) <br /> Take the following measurements with the valve in- <br /> stalled in the tank: <br /> Distance from the 71 SO inlet tube flange to the cast <br /> lug in the 7150 body(see figures),upper tube length. <br /> Note: the Upper Tube Length must be at least 16"to <br /> include the protective bend in the tube. <br /> (D)= 48.25 <br /> Distance from the 71 SO inlet tube flange to the tap and <br /> bottom of lower tube,valve length. (D) <br /> (W)=-- ---- Upper <br /> (U)= Tube <br /> Distance from the 71 SO inlet tube flange to the bottom <br /> of the tank. Note:If a tank bottom protector is present it 3 <br /> may be necessary to add this thickness to dimension <br /> (OPW 6111 &61 TP models add 0.6") (W)valve <br /> (B)= 153.25 I Length, <br /> bottom of <br /> From the tank calibration chart provided by tank manu- cut <br /> facturer find the dipstick number(1)which corresponds <br /> to the 100%volume.

If <br /> the overfill valve is set above the allowable shut-off percent- <br /> age the overfill valve must be removed and replaced. For <br /> reference 40 CFR part 280 Subpart 8 Section 280.20 overfill <br /> valves should be set to a maximum of 45%. <br /> 20 <br />
