A1100 GUARDIAN

OVERFILL PREVENTION VALVE

(with 493192 Installation Kit)

Assembly and Installation Instructions

Important: Read these instructions completely and carefully before attempting to

install and operate this valve. Failure to do so may result in improper valve opera-

tion allowing for a potential storage tank overfill. An overfilled tank can create

extremely hazardous fuel spills which may result in personal injury and property

damage. For further information, please call our Customer Service Department at

(252) 243-0150.

Important: Veuillez lire ces instructions attentivement avant d'installer et d'exploiter

cette vanne. Ne pas le faire peut entraîner un fonctionnement incorrect de la vanne

permettant un potentiel débordement de la citerne de stockage. Un réservoir trop

plein peut créer des déversements de carburant extrêmement dangereuses qui peu-

vent entraîner des blessures et des dommages matériels. Pour plus d'informations,

s'il vous plaît communiquer avec notre service à la clientèle au (252) 243-0150.

CAUTION: Never disconnect the drop elbow from the tight-fill adapter when the A1100

has reached the positive shut-off level. At this point, the tank truck hose is still full and

must not be disconnected until enough fuel has been removed from the underground stor-

age tank to drain the hose. Premature disconnection will result in a hazardous spill and a

potential for personal injury and property damage.

ATTENTION: Ne jamais déconnecter le coude de baisse de l'adaptateur permet le rem-

plissage étanche lorsque le A1100 a atteint le niveau d'arrêt positive. A ce point, le tuyau

de camion-citerne est encore pleine et ne doit pas être débranché jusqu'à ce que suff-

isamment de carburant a été éliminée du réservoir de stockage souterrain pour vidanger

le tuyau. Déconnexion prématurée entraîne un déversement dangereux et un risque de

blessures et de dommages matériels.

ASSEMBLY

Tools Needed

1. 13/64" drill bit 6. hammer

2. hand drill 7. fine half round file

3. tape measure 8. heavy duty pop rivet gun

4. fine tooth hacksaw (24-36 teeth per inch)

Packing List (included with A1100-010)

(1) valve assembly #A1100 (8) pop rivets #564412

(1) hose clamp #564421 (1) o-ring #480049

(1) warning plate #564420 (1) counter sink indenter #564416

(1) drop tube O-ring #561683 (1) Seal-All sealant #566726

(1) 572719 drill fixture

NOTICE:If this valve is to be used with coaxial Stage I drop tube assemblies, you must

order the appropriate special kit for proper assembly:

Standard coaxial (A0070 style) kit #493195

Self sealing coaxial (A0088 style) kit #493197

The A1100 Guardian can only be installed after the containment manhole has

been installed. Existing drop tube may be used only if:

1. Tube is in good condition without holes, cracks, or bends.

2. I.D. of tube will fit over the valve body diameter.

Step 1:If already in place, remove the existing 4” cap, adapter and drop tube

assembly.

Step 2: Find measurement A which is the distance from the top of the tank to

the top of the 4” riser pipe as shown in Figure 1.

If the tank has a manway, make sure to include the height of the manway when

finding measurement A as shown in Figure 2, A = J+H. Consult your tank dia-

gram to determine the proper H dimension. If this dimension cannot be found,

use 6” as the H dimension (typical manway height is 5”-7”).

WARNING: Do not use electrical devices near gasoline vapors, as it could result in fire

or explosion.

AVERTISSEMENT: Ne pas utiliser d'appareils électriques à proximité des vapeurs

d'essence, car il pourrait provoquer un incendie ou une explosion.

WARNING: If the underground storage tank is equipped with a ball float vent

valve, make sure it is not extended below the positive shut-off point of the A1100, or

remove the float vent valve.

ATTENTION: Si le réservoir de stockage souterrain est équipé d'un flotteur évent de balle

vanne, assurezvous qu'il n'est pas prolongée en dessous du point d'arrêt positive de la

A1100, ou supprimer la vanne flotteur de ventilation.

TOP TUBE INSTALLATION PROCEDURE

Step 21: Turn completed assembly upside down and shake vertically to

remove any metal chips left from the drilling process.

The system is now in place and ready for operation.

INSTALLATION OF COMPLETED ASSEMBLY INTO THE TANK

Step 22: Install the O-ring (p/n

561683, supplied) on the top flange.

Step 23: Position the completed

assembly vertically over the riser

pipe with the square cut down.

Carefully lower the completed drop

tube/valve assembly into the riser

pipe.

Step 24: Use the hose clamp

to clamp the warning plate (p/n 564420,

supplied) onto the riser below the threads.

Make sure label is facing up.

Step 25: Reinstall the adapter onto the

riser and torque with an adapter wrench.

Replace the tightfill cap.

Step 17: Subtract 6” from measurement D to obtain the correct total assembly

length E. Measure length E (D - 6”= E) on the assembly from the flanged end.

Mark tube to length E.

Step 18: Secure the hose clamp to the tube.

Step 19: Square cut the the lower tube to

length E.

Optional: 45 degree cut - The shortest

point should start at length E to maintain

the 6” maximum

clearance

requirement at

bottom of tank.

Step 15: Using the indent tool,

countersink one hole and install a

rivet. Apply sealant over the rivet.

Repeat with remaining three holes.

Step 16: Measure from top of riser

pipe to the bottom inside of the

tank, measurement D, Figure 1.

BOTTOM TUBE INSTALLATION PROCEDURE

Step 14: Lubricate bottom of

A1100 valve with Seal-All and

install bottom tube, being careful to

align holes.

Step 13: Slide the 572719 Drill

Fixture on drop tube. Drill the four

holes using the 13/64” drill bit.

Remove drill fixture. File cutting

burrs from end of tube.

Step 4: To determine the top tube cut length, C: Add A and B; subtract 2”.

A + B - 2 = C

Step 5: Place a tape measure at one end of the drop tube and mark length C.

Note: If you are using an unflanged tube, you will require part #566679 collar kit.

Step 9: Slide the drill fixture (p/n

572719, supplied) on the drop tube.

Drill the four holes using the 13/64”

drill bit. Remove drill fixture and set

aside.

Step 8: Remove clamp. File away

cutting burrs to prevent damage to

the O-ring when attaching to the

valve.

Step 10: Lubricate the O-ring (p/n

480049, supplied) with the Seal-All

and insert into the top groove of

the A1100 valve. Lubricate the top

1” of the outside circumference of

the valve with Seal-All.

Step 11: Insert the A1100 valve

into the top tube. Align the holes.

Step 12: Using the indent tool #564416, countersink one hole. Secure with a

pop rivet. Apply sealant over the rivet. Repeat this process with the remaining

three holes.

Step 3: Find measurement B from the chart below. It is the distance from the

maximum fluid height allowed to the inside top of the tank. Calculations are based

on cylindrical tanks with flat ends. For exact dimensions, consult the tank gauge

chart provided with your tank. Use the actual capacity of the tank for calculations.

NFPA30 Guidelines limit tank fill to 95%.

The A1100 Overfill Prevention Valve is not recommended for tanks under 6.5’ in

diameter.

Step 7: Cut tube to proper length

using a fine tooth hacksaw. The

hose clamp acts as a guide.

IMPORTANT: Do not use a power

saw or tubing cutter to cut the

tube.

Step 6: Secure the hose clamp

(p/n 564421, supplied) at cut mark

C from Step 5 as shown.
