NOTICE

Maintenance of the FRG3015-F RV must 
be

carried out only by trained personnel who have been 
authorized by the manufacturer.

10.1 Annual maintenance

1� General visual inspection

•   Check the control station for leaks and retighten sealing 

connections or replace seals, as required.

2� Functional check

•   Check that settings and operating and performance 

parameters are set correctly.

•   Check flow noise during operation.
•   Ask users if there are any noticeable problems.

3� Action to be taken following maintenance work

•   Check that all screw fittings that were unscrewed have 

been retightened and retighten if necessary.

•   Remove all tools, materials and other equipment used from 

the working area.

•  Restore the power supply.
•   Slowly pressurize the FRG3015-F RV and vent it. 
•   Readjust the system settings if required.

10.2 Replacement of wear parts

Please note that the FRG3015-F RV contains parts that, for 
technical reasons, are subject to wear depending on the 
intensity of use, even if the specified care and maintenance 
has been provided. 
This applies especially to mechanical parts and parts that 
come into contact with water and steam, such as seals, 
valves, etc. 
By their nature, defects caused by wear do not constitute a 
fault and are therefore not covered by the warranty or any 
guarantee. Nevertheless, these defects and malfunctions 
must be remedied by trained specialist personnel only. 
Contact your specialist dealer for this.
