<br />GENERAL INSTRUCTIONS
<br />The DPW 71 SO Overfill Prevention Valve is designed for
<br />tight fill, gravity drop applications to help prevent acci-
<br />dental or intentional overfilling of underground storage
<br />tanks. It is Installed In the UST drop tube in place of a
<br />standard drop tube.
<br />The main 7150 valve closes when liquid reaches the
<br />Initial shutoff point A small bypass valve remains open
<br />to allow the delivery hose to drain at 3.5 gallons per
<br />minute. If the delivery truck valve is not closed after
<br />Initial shut-off, the bypass waive will close and will re-
<br />strict all fuel delivery to ensure that the top of the tank
<br />Is not wetted per EPA requirements.
<br />The 71 SO models of the 7150 are designed to be In-
<br />stalled with the following DPW products: Face Seal
<br />Adaptor, DPW Spill Container or Multi -port, Jack Screw
<br />Kit, Rotatable Product Adaptor, and Product Cap.
<br />IMPORTANT
<br />Read these assembly and installation instructions com-
<br />pletely, and carefully prior to starting. Check to make
<br />sure all parts have been provided. Use only the parts
<br />supplied; substitution of parts may cause product fall -
<br />We.
<br />Failure to follow Instructions may cause Improper prod-
<br />uct operation or premature failure which may permit
<br />storage tank overfill. An overfilled storage tan
<br />create hazardous conditions andLor environmental con-
<br />tamination.

<br />7150 Parts Diagram IMPORTANT: The instructions below for the 7750
<br />Overfill Prevention Valve are written for the initial
<br />Upper O -Ring Gasket stage shutoff at 95%, but on beadjusted to shutoff
<br />at any desired tank capacity. Please contact the Au-

<br />per tube must protrude into the tank at least 61/2"

<br />/ tank completely before the top of the tank is wetted
<br />as per EPA requirements.

<br />HOW TO LOCATE THE POSITION OF THE 7150 AT
<br />95% TANK CAPACITY
<br />(Shut-offpoints can beadjustedto anycapacity to
<br />comply with AHJ Requirements)
<br />The length of the upper tube and the placement of the
<br />7150 valve body determine the shut-off Point Fallow -
<br />Ing the standard instructions for the DPW 7150 will pro-
<br />vide for Initial shutoff at 9596. In all cases, the upper
<br />tube length must be a minimum of 6-1/2' plus the
<br />length of the riser pipe. All length measurements are in
<br />Inches.
<br />INSTRUCTIONS
<br />1) Find tank capacity(In gallons) from tank calibration
<br />chart provided by tank manufacturer.
<br />2) Calculate 95% of opacity
<br />3) Locate the 95%volume number onthe tank calibra-
<br />tion chart.
<br />4) Find the dips tick number (X) which corresponds to
<br />the 95% tank volume. And, find the dipstick num-
<br />ber (Y) which corresponds to the l00%volume
<br />5) Subtract the dipstick number 00from the tank di-
<br />ameter (11 to find the upper tube reference number
<br />(2).
<br />() - (X) =1Z)
<br />6) Subtract 2- from (Z) to find the upper tube depth
<br />(Cl.
<br />(Z) -2"=C
<br />7) Is C less than 6-1/2'7
<br />NO Upper tube length is C plus the distance from
<br />the top of the Face Seal Adaptor Installed on
<br />the riser pipe to the Inside, top lip of the storage
<br />tank (A).
<br />CAUTION
<br />Do not remove elastic band from arou nd float until
<br />instructed to do so, as damage to valve may result.
<br />WARNING
<br />Failure to properly connect delivery hose and el-
<br />bow, and/or disconnecting a liquid filled delivery
<br />hose or elbow will result in a hazardous spill, which
<br />may result in personal injury, property damage, fire,
<br />explosion, and water and soil pollution.
<br />• Make sure all connections, Including the hose and
<br />elbow connections, between storage tank and
<br />transport are securely coupled.
<br />• Make sure the lip seal and/or all gaskets inthe deliv-
<br />ery elbow are properly In place to prevent spills.
<br />• Do not operate with damaged or missing pans,
<br />which prevent right connections.
<br />Normal Operation: A How oKick' and reduced flow
<br />signal that the tank is full. Close transport delivery
<br />valve and drain hose Into tank before disconnecting
<br />any hose fitting.
<br />Overfilled Tank Failure of the hose to drain after clos-
<br />Ingthe delivery valvesignals anoverfilled tank Do Not
<br />Disconnect any delivery hose fitting until the liquid kv,
<br />el In the tank has been lowered to allow the hose to
<br />drain Into the tank
<br />WARNING
<br />In the event you are splashed with fuel remove wet
<br />clothing immediately. Skin contact with gasoline
<br />can cause chemical burns and may result in Inhala-
<br />tion of vapors that may be fatal. Never go Inside
<br />confined areas after being splashed a nd never go
<br />near ignition sources.
<br />IMPORTANT
<br />Determine If the underground storage tank Is equipped
<br />with a ball float vent valve, as Illustrated in Figure 24. In
<br />all systems, the shut-off point of the 71 SO must be
<br />reached before the ball float reduces flow to ensure
<br />proper overfill valve operation.

<br />• Sharp 3/16' drill bit with stop
<br />• Punch
<br />NOTE Tastable 7150 models ending with a "7" re-
<br />quire the 7150-TOOLCT or madlfiad 7150 -TOOL or

<br />Upper Tube Length =C+(A)
<br />For tesobte models only, ending In "T':
<br />Upper Tuba Length = C + (A) - 1-1 /2'
<br />YES Upper tube length is 6-1/2' plus the riser pipe
<br />measurement (A).

<br />NOTE: You must And the actual tank opacity num-
<br />ber that correlates to the 6-1/2" +(A) depth for the
<br />station records. This number may also he used for
<br />the purposes of calibrating an electronic tank level

<br />Calibration Chart
<br />Tank Capacity - 10,000 gal., nominal 9.403 gal.
<br />NOTE Use actual capacity Doty
<br />2) 95% of actual tank capacity = 0.95 x 9403 gal.=
<br />8933 gal.
<br />3) The closest number which is less than 8933 gal. Is
<br />8910 gal. Choosing the closest number less than
<br />95% of actual opacity ensures that the Initial
<br />shutoff will occur when the tank Is no more than
<br />95% full.
<br />4) The calibration chart reading of8910 gal. corte-
<br />sponds to a dipstick measurement of 82'.
