V. 2.0
Particular attention should be given to the size of the
Suction filter and/or of any diversion valve (three way valve). The flow capacity of the filter
should be 1.5 times the flow capacity of the pump. An under-sized filter will reduce both
the life of the membranes and the performance of the pump.
EC Machine Directive 2006/42/CE
Following the entry into force of the EC Machine Directive 2006/42/CE, you may find it
useful to note that these regulations do not affect pumps as technically independent units.
They only concern finished machines.

Checks before use
–
Check that the suction hose is not bent and is firmly fixed to the related connection
and to the filter. Restrictions and suction of air pockets should be avoided in any
case which may compromise the proper functioning of the pump.
–
On each use: clean the suction and delivery side filters. This simple operation will
help maintain the pump's efficiency and will ensure the spraying is carried out in the
best way possible.
–
Close all delivery side hoses connected to the use function machinery. An
opening of the connection with the using apparatus can cause significant damage to
persons, animals or property in the vicinity.
–
Check the state of the hoses every time you use the pump. In addition, check that
all connections are properly screwed down and safe.
–
Inspect the pump and its components on a periodic basis. Ordinary maintenance
of the pump will safe-guard your investment.
–
Both in circumstances where the suction connection is made with a water
mains or pressurised system and where there is a depressurised connection, when
the pump is started up the lever of the loader valve should be maintained in the by-
pass position.
–
Check, while the pump is running and AT ITS RUNNING PRESSURE, that the oil is
at the level indicated in the charging tank BETWEEN THE MINIMUM AND
MAXIMUM LEVELS. Should the level be too low, add oil being careful to ensure
the maximum level indicated is not exceeded.
WARNING! Over-filling with oil creates pressure inside the pump. This may give
rise to leaks, the expulsion of the oil seal or may result in a broken membrane.
On each occasion that the oil is topped up or replaced you should only use SAE
30 motor oil.
