4- WARNINGS
4.1- The installation and the setting of the maximum pressure
must be made by qualified staff only, who must have the
required skills to handle high pressure systems and be informed
of the operating and safety instructions contained in this
document.
4.2- The installer must provide the ultimate consumer with the
proper instructions for the correct use of the system the valve is
used in connection with.
4.3- Use soft and filtered water only. In case of salt water and/or
of water containing solid particles of a size exceeding 360µm,
the internal components of the valve will be subject to quick
wear; furthermore, this might compromise the correct functioning
of the valve. Addition agents can be used in the water, provided
that they are delicate, biodegradable and always complying with
the Regulations in force in the Country where the valve is used.
4.4- Use guns and/or other control devices ensuring a perfect
seal when closed. Leakages may compromise the correct
functioning of the valve.
4.5- In the systems for hot water production, the
temperature of the liquid that comes into contact
with the valve must always be lower than the value
stated in this instruction manual and/or indicated on
the valve itself. Avoid the formation of steam or
overheated water.
IMPORTANT: When the temperature of the liquid is
close
to
the
temperature of the valve body is only slightly
inferior. Therefore, take care in case of contact with
the hot surfaces.
4.6- After use and/or before performing any operation on the
system or on the valve, release the pressure by using the
adjustment knob/screw and opening the gun or the control
device for a few seconds. The jet created by the residual
pressure must be directed downwards in order to avoid
damages or dangers.
4.7- For safety reasons, it is advisable to equip the high pressure
feeding line of the system also with a relief or safety valve duly
adjusted.
4.8- To connect the valve to the system it is preferable to use
flexible hoses fitted in a way that they do not form 90° elbows,
throttlings or siphons which could include harmful air bubbles.
The inside diameters of the hoses and fittings must be equal to
the correspondent inside diameters of the inlet and outlet
threads of the valve. Moreover, it is necessary to correctly
choose the type of hose depending on the rated pressure and
flow-rate; the hoses must always be used within their operation
limits as stated by the manufacturer and indicated on the hoses
themselves.
4.9- Tighten the fittings pos. 17 and pos. 20 in order to fix the
valve to the pump head (torque wrench settings as stated at
page 3).
4.10- Before operating the system, it is advisable to start it for a
preliminary test run in order to check that the system is properly
installed.
WARNING: Do not use the valve in the systems covered by
Directive 97/23/CE (PED) - Cathegories I - II - III - IV
5- MAINTENANCE
5.1- Maintenance and repair must be carried out by qualified and
authorized staff only. Before any operation, make sure that the
valve and the system are shut down and made unusable.
5.2- A correct maintenance helps extend the working life and
grants a better performance of the valve.

5.3- From time to time, it is necessary to check that the valve is
clean outside, and that there is no sign of leakage and/or
malfunctioning. If necessary, replace the involved parts. In case
of doubts, contact the after-sales service of Interpump Group.
5.4- Replace the valve parts with original spare parts only.
IMPORTANT: After maintenance, make sure that the
valve is re-assembled correctly and that the initial
conditions are restored. Comply with the torque
wrench setting values and set the pressure again as
described above.
5.5- The valve is entirely made of non-toxic and safe materials;
however, in case of disposal, we suggest you do not disperse it
in the environment but take it to an authorized disposal centre or
contact the nearest INTERPUMP GROUP Authorized Service
Centre.
The valve shall not be tampered with for any
reason and/or used for any purpose other than the
use it has been designed for. In case of tampering,
the manufacturer disclaims all responsibility as to
the valve functioning and safety.
6- WARRANTY CONDITIONS
6.1- The period and conditions of warranty are specified in the
purchase contract.
6.2- Warranty is voided in case the valve is used for improper
purposes, used at higher performances than the rated ones,
repaired with non-original spare parts or if it turns out to be
outside
damaged due to the non-compliance with the operating
instructions or to unauthorized tampering
