Pre-Installation
Before You Begin
This text contains the symbols which are explained below.

NOTE: Notes provide important information about products and installation.
CAUTION: Cautions provide information that you must read to avoid making relatively
moderate errors.
WARNING: Warnings provide special, must-read information. If you ignore a warning you may
create a safety hazard, omit essential data, or make a critical error.
Safety Overview

NOTE: Proper planning and thorough preparation are critical for successful installation. This
chapter outlines basic requirements for the pre-installation phase.
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. Installers should be
instructed in the following safety elements as well as any site-specific safety issues.
•
New duties for which the installer has not previously received training.
•
New processes and methodologies representing new risks that are introduced into the
installation environment.
•
Situations where previously unidentified risks are reported.
•
Hazard Communication (Employee Right to Know)
•
Lifting
•
Safe driving
•
Use of hand tools
•
Confined space
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

Landis+Gyr
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.
Preliminary Checks
1. The installer will verify correct site, as specified on work order.
2. The installer will verify that the site is safe for installer activity and equipment.
3. The installer will notify the customer of installer presence and activity, telling the customer that
meter access is required. If necessary, the installer will have the customer sign the work order.
4. When installing meters, the installer will follow guidelines issued by the utility in addition to
those given in this guide.
5. The installer will never perform an installation during a lightning storm or under excessively wet
conditions.
Site Requirements
The site must comply with the following criteria:
1. There is no chance that another object will be set over the antenna.
2. Some instances may require additional cable.

FCC & Industry Canada Information to the User
Manufacturer: Landis+Gyr
Model Name: American Large Diaphragm GPR
FCC ID: R7PEC6R1S1
IC: 5294A- EC6R1S1
Module Model: GPR
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause
undesired operation.
FCC Class B
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the Instructions, may
cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Consult Landis+Gyr or an experienced radio technician for help.
WARNING: Changes or modifications to this device not expressly approved by Landis+Gyr
could void the user's authority to operate the equipment and the product warranty.
RF Exposure
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20 cm
between the radiator and your body. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
Industry Canada
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to
the following two conditions: (1) this device may not cause interference, and (2) this device must
accept any interference, including interference that may cause undesired operation of the device.

Chapter 1 - Pre-Installation
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils
radiovexempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil
ne doitvpas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage
radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a
type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce
potential radio interference to other users, the antenna type and its gain should be so chosen that the
equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful
communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner
avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par
Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des
autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope
rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une
communication satisfaisante.
Compliance
This apparatus is suitable for Class I, Division 2, Group D Hazardous Locations.
Installation Guide
WARNING: Substitution of components may impair the suitability for Class I, Division 2
applications. Replace battery only with Landis+Gyr part number 40-1590H.

If pulse wheel contact with the adjacent proving pointer tip is unavoidable, 1/4 of the
adjacent proving pointer tip may be removed with diagonal cutters, but only with permission
from the utility customer.

Configuring the GPR
WARNING: Before performing the following steps, determine the direction that the GPR will
face. The GPR must face away from nearby walls and toward the nearest MCC or
Concentrator. Consult Appendix C, Schlumberger Changing GPR Orientation, for
instructions on setting GPR direction.
The GPR must be programmed with customer-specific requirements. The GPR, when installed for
the first time, will start operation in Install Mode. During Install Mode, the GPR will auto register to
the Network and then go through an auto-configuration process.
Applying Water Sealant to Circuit Board Connections
Dow Corning 4 Electrical Insulating Compound is recommended as a sealant to prevent water
intrusion into the GPR Pulse Input and Battery circuit board connections.

3. Install the two screws and lock washers. Tighten the screws to 30 inch-pounds (+ / - 2 inchpounds).
CAUTION: If the meter’s pipe route prevents installing the GPR as described in this manual,
the GPR may be mounted in a remote location away from the meter, such as on a wall or a
gas pipe. The maximum cable length between the Index Cover Assembly and GPR must not
exceed 200 feet.
In a remote GPR Mounting environment, Pipe Bracket Kit 45-0080 may be used to install the
GPR on suitable plumbing pipes. Remote GPR mounting is beyond the scope of this manual.

Direction
The GPR must face away from nearby walls and toward the nearest MCC or Concentrator. The GPR
may be oriented in three different directions:
•
Forward toward the front of the meter
•
90 degrees toward the left side of the meter
•
90 degrees toward the right side of the meter
The previous instructions show the GPR facing towards the front of the meter.
The following figures show the other two possible orientations.

2. Determine the appropriate GPR direction.
WARNING: The GPR must be mounted in the forward-most position on the lower bracket so
that the gas pipes do not interfere with data transmissions. Refer to the following figures for
additional detail.

WARNING: A right-facing GPR must have the cable routed as shown in Figure D - 5. The cable
must not be routed around the edge of the GPR bracket (Figure D - 6.), where it may be
exposed to unknown hazards.
