7.1. MAINTENANCE
Carry out the following maintenance work.
7.1.1 MEMBRANE PRESSURE
The membrane in the interior of the boiler must be
at a pressure 1.3 bars when there is no water in the
boiler. Check the membrane pressure once every
three months.
To check the membrane pressure there is an air valve
(number 4 in section 4.3) similar to that found in
bicycle and car wheels.
Check the pressure of the membrane is below 1.3
bars by adding air up to this number.
7.1.2. OTHERS
This pressure group does not need any other
maintenance. We recommend a visual check up every
three months checking the start up pressure (1.5
bars) and the stopping pressure (3 bars); looking for
any water leakages, loose parts and check the state
of all connectors. This way, you will guarantee a long
lasting machine. Should you spot any anomalies,
repair or take to your nearest after sales service.
