PREVENTIVE MAINTENANCE

1. Annually, conduct a visual inspection of the flapper valve located inside the

A1100EVR overfill prevention valve. Begin by removing the spill containment

lid and fill adapter cap. Looking down over the tank fill riser opening, verify

that the flapper valve is open and free of any foreign objects that can block

or restrict the flow of gasoline into the underground storage tank during a fuel

delivery.

2. Annually, verify leak tightness integrity of the A1100EVR overfill prevention

valve by performing ARB test procedure TP-201.1D.

3. If the A1100EVR overfill prevention valve fails to pass the leak tightness

integrity test, replace the drop tube o-ring with the EMCO o-ring kit p/n

569461.

PERFORMANCE SPECIFICATIONS

This component was factory tested to, and met, the following specifications.

1. TP-201.1D - Meets or exceeds the allowable maximum leakrate of 0.17 CFH

@ 2.00 inches of water.

IMPORTANT: Leave these installation instructions, product warranty

registration card and the warranty tag with the station owner and/or

operator.

CAUTION:

1. Always barricade to keep pedestrians and vehicles from accessing the

storage tank area during preventive maintenance and/ or compliance testing

of the EMCO phase I EVR system.

2. If the underground storage tank is equipped with a ball float vent valve, make

sure it does not extend below the positive shut-off point of the A1100EVR

overfill prevention valve. If so, the ball float valve must be removed to allow

proper operation of the A1100EVR overfill prevention valve.

3. Never disconnect the delivery elbow from the fill adapter when the

A1100EVR overfill prevention valve has reached the positive shut-off point of

95% total capacity. Note the tank delivery hose is full and must not be dis-

connected until enough fuel has been evacuated from the underground stor-

age tank. This will allow the tank delivery hose to drain, and to safely discon-

nect from the fill adapter. Premature disconnection will result in a hazardous

spill and/or a potential for personal injury and property damage.

4. Once the A1100EVR overfill prevention valve is completely assembled, the

Seals-All Sealant must cure for a minimum of 24 hours before installing

into the underground storage tank.

Service Tool Required:

Model #

Place tape measure at the end of the top tube

(riser collar) and measure down to distance E.

Carefully cut the drop tube to the required

length. Use a hacksaw equipped with a fine

tooth blade to ensure a straight 90-degree cut.

An angled cut is permissable, but the 4”-6” dis-

tance from the bottom of the tank must corre-

spond to the top of the cut as shown.

20. Remove all metal chips or debris left from cutting or drilling. Shake the

A1100EVR overfill prevention valve in a vertical position. Verify that the

A1100EVR drop tube o-ring is installed properly. Locate the A1100EVR

overfill prevention valve over the tank fill riser opening with the A1100EVR

collar pointing upward. Carefully lower the A1100EVR overfill prevention

valve into the tank until the A1100EVR collar is resting on the riser pipe.

21. Install warning plate on the riser using the hose clamp provided.

A1100EVR Overfill Prevention Valve Top Drop Tube Cut Length

1. Find measurement A, the distance from the inside top of the tank to the top

edge of the riser pipe as shown in Figure 1.

If the tank has a manway (Figure 3), make sure to include the height of the

manway when finding measurement A as shown in Figure 2, A =J+H.

Consult your tank diagram to determine the proper H dimension. If this

dimension cannot be found, use 6” as the H dimension (typical manway

height is 5”-7”).

When installing the A1100EVR overfill prevention valve below the spill

containment drain valve, measurement A is the distance between the inside

top of the tank to the top edge of the A1100EVR overfill prevention valve

seat as shown in Figure 2.

15. Apply pipe thread sealant compound to the male threads of the A1100EVR

base.

16. Manually tighten both

top and bottom drop

tubes to avoid cross

threading.

17. Use two fabric strap wrenches to permanently tighten.

IMPORTANT: Once the Seals-All sealant has cured for a minimum of 24

hours and before installing the A1100EVR overfill prevention valve into the

underground storage tank, a leak tightness integrity test must be performed.

18. Test the A1100EVR overfill prevention valve by sealing both ends with

inflatable plumber’s plugs. Apply a maximum pressure of 2 inches of water

column. Should the leak rate exceed the allowable limit of 0.17 CFH, locate

the leak point by spraying soap solution along the outside of the A1100EVR

overfill prevention valve.

IMPORTANT: Do not exceed the maximum presssure of 2 inches of water

column. This will damage the A1100EVR overfill prevention valve and result

in voiding the warranty.

for tanks under 6.5 feet in diameter.

3. Top Tube Cut Location, Measurement C: Add measurements A and B.

Place tape measure at the 95% fill mark on the valve and measure up the

tube as shown. Mark and cut the tube at the C measurement length.

Example: Top drop tube cut length, C = A + B

14. Once finished with steps 11 through 13, clean and remove all excess

sealant around the top of the A1100EVR collar and rivets.

IMPORTANT: The Seal-All sealant must cure for a minimum of 24 hours

before installing into the underground storage tank.

10. Apply a 1/2 inch bead of Seals-

All Sealant around the 480049 o-ring

and outside area of the A1100EVR

collar. Verify the o-ring is properly

secured inside the machined groove.

Do not apply sealant to the 569461

drop tube o-ring.

11. Slide the A1100EVR collar inside

the top end of the drop tube and align

the four holes.

12. Using the indenter tool and a

hammer, apply a sharp blow to

counter sink each individual hole

before attempting to install the

mounting rivets.

13. Using only the factory supplied

rivets, apply a good amount of the

Seals-All Sealant around the base of

each rivet before installing into each of

the four holes. Using the rivet gun,

permanently fasten the A1100EVR

collar to the top of the drop tube.

4. Carefully cut the top drop tube to

the required length. Use a hacksaw

equipped with a fine tooth blade to

ensure a straight 90-degree cut.

IMPORTANT: Do not use a power

saw, pipe or tubing cutter as this

may result in damage to the top

drop tube, voiding warranty.

5. Slide the EMCO Drill Fixture p/n

566675 onto the end of the top drop

tube until the edge bottoms out

against the inside ridge.

6. Drill four 13/64 diameter holes

through the top drop tube. Remove

the drill fixture from the top drop

tube. Using a de-burring tool

equipped with a #10 blade, remove

any sharp burrs around the inside

area of the mounting holes.

7. Using a fine blade hand file,

remove all burrs from the inside and

outside edge of the top drop tube.

File the edge of the top drop tube

square. File the inside surface of the

holes. Remove all rough edges.

A1100EVR Collar to Top Drop Tube

8. Using a de-burring tool equipped with a #10 blade, remove the sharp cutting

ring from the inside edge of the top drop tube. Lightly sand the inside area of

the top drop tube and mounting holes using 150-grit size emery cloth. Clean

and remove any sanding debris.

IMPORTANT: Failure to perform this procedure will damage the o-ring seal

during the installation of the A1100EVR collar, voiding warranty.

9. Remove the o-ring (p/n 480049)

from the A1100EVR collar groove.

Lightly sand the outside area using

150-grit emery cloth. Clean and

remove any sanding debris.

may result in damage to the top

drop tube, voiding warranty.

5. Slide the EMCO Drill Fixture p/n

566675 onto the end of the top drop

tube until the edge bottoms out

against the inside ridge.

6. Drill four 13/64 diameter holes

through the top drop tube. Remove

the drill fixture from the top drop

tube. Using a de-burring tool

equipped with a #10 blade, remove

any sharp burrs around the inside
