Pre-Installation
Proper planning and thorough preparation are critical for successful installation. This chapter
outlines basic requirements for the pre-installation phase.
SAFETY OVERVIEW
Prior to starting the installation process, you must develop and launch an installer safety training
plan for initial, refresher, and ongoing safety training. Ensure that installers receive appropriate
initial and refresher training to meet their specific safety-related responsibilities. Safety training
must be provided when:
•
An existing installer assumes new duties for which he or she has not previously received
training.
•
New processes and methodologies representing new risks are introduced into the installation
environment.
•
Previously unidentified risks are reported.
The installation supervisory team assumes responsibility for ensuring that installers are properly
trained, authorized, and continually qualified to perform their work. The team must also take
responsibility for the safety of their installers and to assure safe work methodologies. Installers must
understand that their supervisor’s responsibility does not relieve them from their individual
responsibility to perform the work safely and to follow all safety rules and procedures applicable to
their work.

Your supervisor carries shovels, spades, hack saws, other specialty tools, and
ladders. Take care to check the work area each time you change locations. Be
certain there are no tools left behind.
Do not clean the module or the cover on-site. Static Discharge may result, can
ignite a natural gas leak, and is a risk of fire or explosion.
RF Busters
Verify that the RF Buster is working correctly. Press and hold the push button Switch. The LED
lights red, and the internal speaker sounds for approximately 1/2 second. If nothing happens or the
LED lights and speaker sound continuously, then the 9V battery is probably low and needs to be
replaced.

Install Material
The Gas Meter Exchange process consists of using predetermined route information that identifies
the meters that need to be retrofitted with the Landis+Gyr Gas Meter Module and methods for
recording data to document the installation. The route information describing the account address,
existing meter ID, estimated meter reads, and any special instructions that describe circumstances
unique to that particular account is supplied at the Cross Dock.
From the Cross Dock, obtain the Meter Modules to be installed. Installers will be issued data that
includes the route, address, meter ID, and estimated read for the particular meters, plus specific
instructions and required field collects information.
Each installer must validate that the route information is correct before leaving the Cross Dock.
Meter Compatibility
This Gas meter Compatibility List is the result of retrofit experience and feedback from American
Meter.
Every attempt has been made to ensure the accuracy of the information in this table. There may be
limitations to compatibility unknown to Landis+Gyr due to changes made which L+G has been
unable to document through our research and substantial meter library. Any questions about the
compatibility information should be forwarded to your L+G representative.
Metal indexes cannot be used and must be replaced. Only indexes with plastic
gears and pointers are supported.

There are two part numbers used. The Long Post unit, model # 26-1204, is used for pointer-type
indexes. The Short Post unit, model #26-1237, is used for odometer-type indexes. Beyond post
length, modules can be differentiated in multiple ways. Check the lower bar code label on the side of
the module cover. The model number is listed at the beginning of the label, and the last two
characters that appear will be either “LP” or “SP” to indicate the model unit.

Figure 2 - 3. Long and Short Post Module Cover internal differences
The post length difference in the two models is only about a quarter-inch, but this critical installation
parameter ensures accuracy and functionality. Note also the “1” and “2” cast into the cover next to
the sensor board, with “2” designating pointer index usage and “1” being for the odometer index.
Installing the 26-1204 on a meter with an odometer index may cause the
sensor to break.
Installing the 26-1237 on a meter with a pointer index may cause the
endpoint to count incorrectly.

On-Site Preparation
Arrival at Install Site
Upon arriving at the installation site, verify the address in the Handheld. Check the Handheld
for special instructions for that site (for example, medical customer, dog, key required for access
to meter, meter location, and so on). If a medical alert code appears in the Handheld for that
address, they are to skip the install, enter an appropriate skip code, and move to the next
exchange. A medical alert tag may be located on the electric meter.
If the installer comes across a meter where a medical alert code appears in the Handheld for that
address, they are to discontinue the exchange, enter the appropriate skip code, and move to the
next exchange.
Verify that the meter ID of the meter at the address is the same as that in the Handheld record; if
not, verify it a second time. If the meter ID does not match, record the information, including
mismatched ID on hard copy, record skip code of meter ID mismatch, and call your Supervisor
for direction.
Verify that the seals are intact and present. If the meter is unsealed and there is no evidence of
tampering, complete the meter exchange or module retrofit. If there is suspected tampering or
evidence of diversion, do not complete the install. Record the diversion on hard copy, enter the
skip code of diversion in Handheld, and call your supervisor immediately.
If the premise is vacant and the service is shut off at the service riser valve, complete the meter
exchange if at all possible. If you are unable to gain access to the premise, finish your route and
then try again before returning to the Cross Dock. Enter appropriate code in Handheld.
Inspect the meter for any gas leaks, unsafe conditions, excessive rusting, or damage. While
performing this technical review, inspect the meter for poor conditions such as excess rust,
tampering, or odor of gas. If you judge the meter is seriously damaged, report it, enter the
appropriate code in the Handheld, and call your supervisor for directions.
If it is determined that the meter has no unsafe conditions, you are ready to proceed with the
module retrofit. Data will be required to be entered into the Handheld. If the reading is out of
range (indicated by a prompt on the Handheld), then retype the meter identification numberʹs
last four digits to re‐verify the correct meter. Reenter the gas meter index read into the
Handheld.

See ʺTo Begin Meter Module Retrofitʺ on page 43 for information about module exchange
instructions.
If the meter is to be exchanged and it is partially buried, enter a skip code of “buried” and move
to the next account. If a tilted meter is to be exchanged, perform the exchange and correct the
tilt. If a module is to be installed on a tilted meter, complete the install, and enter a skip code of
“tilted.”
If the installer is met by a violent or threatening customer, immediately leave the premise and
call your Supervisor. If necessary, dial 911, after which you will enter into the Handheld and on
the hardcopy a skip code of “violence code.”

Battery Change Out
When the NOC analyst notices that the battery flag (R) is set, it could be due to:
•
a single end-point occurrence, where the end-point may require more current to operate. In this
case, a single battery needs to be replaced
•
occurrence on several end-points, where a battery change out program needs to be implemented
within the following year
•
the flag being set during the coldest part of the day, where the battery may have less than 20% of
energy left (2-4 years of service time)
•
occurrence more often even during the daylight hours. In this case, the battery has even less
energy remaining (1-2 years of service time)
To Change Out The Battery
Swipe a magnet on the left hand side of the main board compartment
Listen for up to ten beeps on the RF buster (which ensures that the latest data is saved to non‐
volatile memory)
Remove the four meter cover mounting screws
Remove the Gridstream M120 module from the gas meter
Open the battery compartment door
Replace the battery assembly with a new one (battery model #40‐1590H)
Close the battery door
Replace the module onto the gas meter using the four original mounting screws
Insert two new security seals into the housing.
..
If the gasket is old and no longer provides a good meter to module seal, replace
the meter gasket with a new one.

Place the corner of the RF Buster containing the magnet by the location of the reed switch on the
Meter Module.
Continue to press the button. Hold the RF Buster within six inches of the module. The magnet
triggers ten RF transmissions from the gas module, with each transmission separated by one
second. The RF Buster LED lights and the internal speaker sounds about one‐half second for
each transmission detected.
If the module is functional, it will transmit.
If the RF Buster does not detect a transmission from the module, store the RF Buster. Remove the
four module screws, place the module in its original packing bag, mark the module “defective,” and
return it to the meter shop.
