9. MAINTENANCE PROCEDURE
The pump was designed and built in order to minimize maintenance requirements.
To simplify maintenance, it is recommended to install it in an easy to reach position.
Periodically check the pipe joints to detect any leaks. Furthermore, always keep the pump clean to be able to quickly detect
any leaks or defects.
Check if the filter is clean after every 2000 hours of operation.
The machine does not require any special equipment for any control and/or maintenance activity. It is recommended to use
tools and personal protective devices suitable for use (gloves) and that are in good condition according to current regulations to
prevent damage to people or machine parts.
In the case of doubts and/or problems that cannot be solved, do not try to discover the reason by disassembling machine parts,
but contact the DROPSA S.p.A technical office.
10. DISPOSAL
During machine maintenance, or if it is demolished, do not dispose of the polluting parts in an improper manner. Refer to the
local regulations for their correct disposal. When demolishing the machine, the identification plate and all other documents
must be destroyed.
