Installation Manual

RDM-UM-00059-EN-05 (January 2018)

SAFETY INFORMATION

The installation of the Recordall® Disc Series Meters must

comply with all applicable federal, state, and local rules,

regulations, and codes.

Failure to read and follow these instructions can lead to

misapplication or misuse of the Recordall® Disc Series Meters,

resulting in personal injury and damage to equipment.

PRODUCT UNPACKING AND

INSPECTION

Upon opening the shipping container, visually inspect the

product and applicable accessories for any physical damage

such as scratches, loose or broken parts, or any other sign of

damage that may have occurred during shipment.

OTE:NIf damage is found, request an inspection by

the carrier’s agent within 48 hours of delivery

and file a claim with the carrier. A claim for

equipment damage in transit is the sole

responsibility of the purchaser.

METER PREINSTALLATION

Take into account the following considerations before you

begin an installation:

• Inspect the piping around the meter for suitable

conditions. The service line, valves, connections and

meter must be watertight. Repair the piping system if

pipes are corroded or damaged.

• Install the meter in the pipeline in a horizontal position

so that the flow arrow on the meter housing points in

the same direction as water flow. Registration should be

upright and protected from damage, freezing,

and tampering.

• Position the meter so it is accessible for installation,

removal and reading.

• Verify that a suitable electrical grounding wire is properly

attached to the upstream and downstream pipe

connections of the meter. The grounding wire provides an

alternative path for any electrical current that may exist

across the opening in the line.

• Close the curb (shutoff) valve to relieve water pressure in

the line before starting the cutting operation. Provide a

high-quality upstream shut-off valve with a low

pressure drop.

• When cutting into a new section of service pipe,

flush the pipe to clear chips, pipe dope or other

plumbing residue.

• The installed meter must not be an obstacle or a hazard

to the customer or interfere with public safety.

• DO NOT ATTEMPT TO USE ANY METER AS A LEVER OR

CROWBAR TO STRAIGHTEN A MISALIGNED METER

POSITION. THIS COULD DAMAGE THE METER.

• DO NOT ATTEMPT TO INSTALL A METER INTO AN

OPENING THAT IS TOO LONG BY FORCING THE PIPING

INTO PLACE WITH THE METER'S COUPLING NUTS. THIS

WILL CAUSE SERIOUS DAMAGE TO THE THREADED ENDS

OF THE METER AND HOUSING.

• TO AVOID POTENTIAL PROBLEMS, CORRECT ANY

IRREGULARITIES IN PIPE SPACING AND MISALIGNMENT

BEFORE PLACING THE METER INTO ITS POSITION.

RDM-UM-00059-EN-05

SPECIAL INSTRUCTIONS FOR REMOVING A METER

DEPRESSURIZE THE LINE BEFORE STARTING ANY DISASSEMBLY OPERATION. REMOVING A METER THAT IS UNDER LINE

PRESSURE CAN RESULT IN COMPONENTS BECOMING PROJECTILES, CAPABLE OF CAUSING PERSONAL INJURY.

SPECIAL FITTINGS AND ACCESSORIES

To accommodate 5/8 in., 3/4 in. and 1 in. meter installations, special fittings and accessories are available. Metal meter setters,

re-setters, horns and meter yokes are available for holding the service pipe in proper alignment to the meter and laying

length spacing. The metal setters and meter yokes can provide an electrical continuity to protect meters and consumers from

electrical shocks.

NL bronze connections are available from Badger Meter. To compensate for minor service pipe and setting misalignment for a

5/8 in., 3/4 in. and 1 in. meter, plastic swivel connections are also available.

Cast iron or NL bronze companion flanges are available for a 1-1/2 in. and 2 in. meter.

INSTALLING RECORDALL DISC SERIES METERS

Outdoor Installations

When installed outdoors in a meter box, the disc meter should have a two- to three-inch clearance

to avoid damage or strain to the service piping or meter, and to accommodate any "settling" that

may occur after installation.

The service pipe in the meter box should be properly bedded to ensure that it is not axially

misaligned and that it lays evenly on the bottom of the pipe trench. The backfill material covering

the pipe should be placed appropriately to maintain pipe alignment in the event of eventual

ground shifts. This will prevent damage to the pipe.

The service lines and the water meter must be protected from freezing. The earth covering the service line must be adequate

to prevent frost penetration. Due to the smaller volume of water, service line pipes will freeze sooner than the main

distribution line.

For those locations in which a remote possibility of freezing exists, thermoplastic or lead-free bronze alloy meters with cast

iron bottoms are recommended.

The meter box pit should be excavated below the frost line. Even though the meter itself may be positioned above the frost

line, the warmer air rising from the earth below the frost line will reduce the possibility of freezing.

Indoor Installations

As a precautionary measure when working with metallic pipes, indoor settings must be checked

for electrical continuity through the service pipe before you remove or service a meter. American

Water Works Association (AWWA) policy specifies that service pipes must not be used as an

electrical ground. Check your local codes and practices. A permanent ground strap or metal setter

must be used if electrical grounding to water services is required in your community.

This is especially important for the engineered polymer meter.

To prevent floor damage, close the valve downstream from the meter before installing or removing a meter.

INSTALLATION INSTRUCTIONS

To prepare for meter installation, follow these steps:

1. Close the meter's inlet-side valve.

2. Open a faucet and wait until water ow stops, to depressurize the system. Do not remove the meter until the

ow stops.

3. Check valves and make necessary repairs to the curb (shut-o) valve or inlet side valve if necessary.

4. Close the meter's outlet-side valve. Protect the floor below the meter against potential spills or leaks that could occur.

Protect the coupling area from debris, so that the new meter will not be damaged or contaminated.

5. To replace an existing meter, continue with Step 6. To install a new meter, skip to Step 8.

6. Loosen meter couplings or ange bolts and remove the meter and the old gaskets in the coupling nuts.

MPORTANTI

Replace the entire connection set when you replace the meter (or earlier, if necessary).

7. Clean the coupling nuts or ange ends, removing any pipe dope or dirt from the threads or ange ends.

8. Check the existing setting for proper alignment and spacing. Correct any misalignment and spacing in the setting.

9. Place the new connection gaskets inside the connection coupling nuts.

10. Install the meter in the pipeline in a horizontal position so that the flow arrow on the meter housing points in the

same direction as water flow.

5/8 in. to 2 in. Threaded Ends

11. Start the coupling nuts at the threaded meter ends. Verify that the nuts are properly aligned to avoid cross-threading

or damage to the meter ends. This is especially important for the engineered polymer meter.

An effective method for starting a coupling nut is:

a. Position the nut squarely against the meter's spud end.

b. Turn the nut counterclockwise (in reverse) while holding the nut against the meter spud end. When the rst

threads on both the nut and the spud end coincide, you will hear a slight click and feel the nut move into the

starting position.

c. Tighten the nut by hand until it is snug.

d. With an open-end wrench, apply a partial turn. Do not over tighten. For plastic swivel connections, a

one-quarter turn is usually sucient.

1-1/2 in. to 2 in. Elliptical Flange Ends

12. With meter and gaskets in place, tighten the ange connection bolts. Verify the nuts are properly aligned to avoid

damage to the anged ends.

PROTECT AGAINST LEAKAGE

Before turning on the service water, use care to protect against potential leakage.

1. Shut o the valves on both the inlet and outlet sides of the meter.

2. Open the curb (shuto) valve slowly to pressurize the service line to the meter.

3. Slowly open the meter's inlet-side valve to ll the meter.

4. Check for leaks around the meter and its connections.

5. Slowly open the meter's outlet-side valve to pressurize the consumer side of the system.

6. Open a faucet to allow entrapped air to escape.

7. Once water is owing normally, turn o the faucet.
