The device has hardly any consumption and wear parts, but to maintain the accuracy of the measurement
an annual service calibration with special gases is necessary. Elster GmbH also recommends an annual
check of the filter in the process gas inlet in order to prevent errors.
The service calibration and all other work, which require an opening of the device,
should be carried out only by the Elster GmbH or of Elster authorized / trained
persons for safety reasons.
The Instrumentation compartment may only be opened by Elster approved
personnel. These specialists must additional observe the service manual.
Irrespective of this always:

additionally required, when you open the instrumentation area.

The process gas inlet is equipped with a filter to protect the interior of the device from contamination. It
can clog when feeding non-specification-compliant gas or by failure of the upstream filter system. If
clogged the filter must be replaced.
Since the filter is neither visible nor accessible in normal operation, clogging can
only be determined by means of external reactions. Example "Process gas pressure
alarm" is given out and the device meet all conditions specified in chapter 10. If
there is any suspicion of clogging, please contact Elster GmbH to do more tests or
exclude other causes.
After several years of operation of wear and aging, additional maintenance and repair may arise.
Examples are battery replacement (approximately 10 years) and replacing of seals and IR-Transmitter!
Similarly, factory maintenance must be carried out
services or the housing is damaged. This work requires, depending on situation; the opening of device,
complete disassembly or a return to Elster GmbH.The required work (with the exception of the complete
device replacement) can only be done through Elster Service or by Elster trained staff.
For example, the housing may only be repaired by Elster GmbH because dimensions of the flameproof
joints are detailed in the manufacturer's design documents and are not part of an individual's general
knowledge. Please contact Elster GmbH.
Explosion-proof equipment not repaired by Elster GmbH may be not used again
until it has been checked by an acknowledged expert and matches the
manufacturer's design documents.
