WARNINg!
Use of suction filters with closing valves of an inadequate capacity will immediately void the warran-

• The on line filters must only be installed after the regulating valve, on the delivery line before the nozzles.
• Suction filters with automatic closing valve must be sized with an adequate capacity after inspection of the clear
passage area, which must not be less than that of the pipe fitting supplied with the pump.
• The filtering capacity of the suction filter must be al least two and a half times the pump flow rate, and the recom-
mended diameter of the holes must be 32 mesh for charging cartridge from pump suction.
