Maintenance
• Check the strainer basket (at least once a month)
Taking out the strainer basket does not require any special tools.
It is imperative to check the strainer basket to avoid too large an amount of impurities which
will cause it to clog up.
In normal conditions of use, this operation should be undertaken at least once a month, but
this can vary, depending on the quality of the product and the amount delivered.
• The reader head unit
Please see the user manual for instructions and maintenance.
• Metrological check of the measuring units
- A metrological check at the time of use is known as a ‘primitive’ check.
- An annual metrological check is known as a ‘periodic’ check.
(These operations are undertaken by appointed companies or by SATAM in the context of the
MID directive)
If during a measuring operation, the most substantial flow exceeds the tolerance, it can be
readjusted by means of the continuous regulating system AB35 or by changing the correction
factor on RUBIS, in the case of EMR3 or on an EQUALIS L the adjustment is automatic.
IMPORTANT NOTICE
In no circumstances may the installation manager ask the manufacturer to undertake this
operation on site.
The fitter has to arrange thus necessarily a capacity of 1000 liter capacity minimum, allowing
to make the metrological control during the starting.
It is not advisable to clean the counter unit using a high pressure device, which could cause
damage to the reader head.
