The measures of prevention and protection described in this manual do not determine the level of safety
required if the heads will not be used according to the provisional use, nor if they were not installed and
subjected to maintenance according to the terms of use or appropriate requirements.
1.2. Field of Application
The head is designed
to be used
with water up to 90°C, with addition of mild detergents or disinfectants. In
case of use with special or even flammable liquids (different viscosity, chemical harshness or other), please
contact our technical department. The head
shall
be used within pressure, temperature and RPM speed
limits
reported
in the official documents, such as declaration of conformity, certificate of assembly and
technical data reported on the instruction manual.
The cleaning liquid shall have an ignition temperature of minimum 50 k over the maximum exterior
temperature of the appliance’s surface where the cleaning liquid is utilized.
The room temperature when the appliance is working
shall
range between 0 / + 90°C.
Environmental conditions allowed are those reported in the EN 1127-1:
2011
. For
a
different use, please
contact the manufacturer for a customized study.
Only when it’s used according to
the
prescriptions included in this manual and in correctly tackling residual
risks raising from its use, does this head assure a level of protection high enough as to not generate
potential sources of priming, when installed in a potentially explosive environment.
The appliance in question grants that potential sources of priming are not activated in normal functioning and
even in case of foreseeable and rare failure or malfunction.
Breakage or failure to the appliance can happen. In that case, it is necessary to check the causes of failure.
When these are traced down to the appliance, they must be removed.
Note 1
: the appliance reaches a max. surface temperature according to the temperature of the fluid pumped in. The
temperature class must take into account the safety factor 0,8 aimed for appliances of class 1, see table below
