prevents the accidental leakage of the liquid being pumped.
•
Do not tamper with controls and safety devices.
•
The connection of the machine that incorporates the pump to the mains electric supply must
be carried out by a Quali ed Electrician according to the current regulations in the country
where it is to be used.
•
If the machine that incorporates the pump operates with a combustion engine, it must not be
used in enclosed spaces.
5.1 PRELIMINARY PROCEDURES
«
CAUTION
•
Complete the Manufacturer’s recommended preliminary procedures for the machine that
incorporates the pump.
•
Check that all the delivery parts are closed or connected to applications, which are closed
(for example, closed tap or closed sprinkler lance).
•
Do not exceed the maximum level of accumulator in ation pressure (when present), indicated
in the following table, at any time.
•
A
Skilled Technician
must complete the special maintenance procedures.
a)
When the pump is not in use, check that the oil level either corresponds to the reference notch
on the volumetric compensator (4) or is visible from the level cap (also see  g. 6), according to
the type of pump.
Remember that the level of the oil must always be checked when the pump is not in use and has
cooled down completely.
Refer to the types of lubricants listed in the
“FEATURES AND TECHNICAL SPECIFICATIONS”
section if it is necessary to top up the oil.
«
CAUTION
•
Pumps BP 40/15, BP 60, P48 and P48 AP do not have a volumetric compensator therefore,
contact a Skilled Technician if a top up is necessary
b)
Check that the in ation of the pressure accumulator, if present, is correct using a common
compressed air gun with a pressure gauge, i.e. the type used to check the pressure of motor vehicle
tyres.
In ation depends on the range of pressure that the pump must operate in, according to the following
table:
WARNING
•
For applications where the pump uses a cardan shaft, strain on the pump shaft must be avoided
caused by incorrect use of the cardan shaft (poor lubrication of moving parts, incompatible
turning radius for type of cardan shaft used).
•
In case of use at very low temperatures, check that ice does not form inside the pump.
•
Complete all routine maintenance, especially concerning the oil.
