6 Maintenance
This section explains the various steps involved in replacing the battery in the gas meter and replacing the
meter itself.
Important:
The following procedure is to be performed by authorised personnel only.
Appropriate electrostatic discharge (ESD) procedures must be followed before opening the meter
cover.
Under no circumstances should the battery be changed if gas leakage is observed.
6.1 Replacing the battery in the Liberty EG4v12 gas meter
The gas meter battery is designed to last for at least ten years under regular use and operating conditions.
More frequent use of the gas meter’s interface and excessive operation of the valve will cause a higher battery
discharge and may result in a shorter lifespan. The procedure for changing the battery in the gas meter is as
follows:
Step 1: For safety reasons, ensure all appliances are turned off, or the emergency control valve is in the
OFF position.
Step 2: Break both battery cover seals (white colour) on the
front cover by using a suitable removal tool.
Step 3: Unscrew the special screws (M4) using a slotted
screwdriver.
