OPW Model Number:71S00

PART 1) Proper height setting calculation
Maximum Tank Volume per: Tank Chart A gallons
Max shut off requirement for Flapper is 95% B 95%
Multiply Maximum tank volume by 95% C gallons
Use tank chart to determine height of calculated volume D inches
Measure top of fill riser threads, or face seal adapter when used, to tank top E inches
Tank diameter From Chart F inches
Upper Tube in tank (G) F - D = G G inches
Subtract 2 inches from upper tube in tank G - 2"= H H inches
Calculated minimum upper tube length (I) H + E = I I inches
Actual measured upper tube length (Without fill
adapter) (J) J inches
PART 2) Device certification criteria evaluation
Criteria 1
Does the overfill prevention device meet the 95% requirement?

Criteria 1a If the final shutoff volume is installed greater than 95%, is there at
least 250 gallons of ullage above the overfill device activation point
to ensure that none of the tank top fittings are exposed to product,
meeting the criteria established in EPA 280.20iic and per OPW
installation guidelines.

Criteria 2 Is the Actual measured upper tube length 6.5 inches
or more than the fill riser? (J must be 6.5" or more
than E)

Criteria 3 Does the overfill prevention device function as
required? (Inspect the device for damage,
contamination, freedom of movement,
weakening due to wear and corrosion)
PART 3) Device Certification PASS / FAIL
Technician certifies that the device is operationally
compliant.
