3.4.9- Once the setting has been accomplished, we
suggest you seal the adjustment screw in order to
avoid any unintentional variation of the pressure and
indicate on the valve itself the actual value of the
setting pressure that has just been determined.
3.4.10- During the normal functioning of the system, the
maximum working pressure (WP) should be kept within
approx. 85% of the setting pressure of the valve (SP).
Interpump Group disclaims all responsibility
for any damages caused by the inaccurate
adjustment of the setting pressure and/or by
any incorrect use of the valve that cannot be
reasonably predicted.
IMPORTANT: during use, never exceed the
maximum values of pressure, flow-rate and
temperature as stated in this document
and/or indicated on the valve.
4- WARNINGS
4.1- The installer must provide the ultimate consumer with
the proper instructions for the correct use of the system the
valve will be used in connection with.
4.2- The fittings used to connect the valve to the system
must be suited to the valve performance features.
IMPORTANT: to obtain an effective functioning of the valve,
we suggest you install it by the component or in the system
section that you wish to protect most from pressure peaks.
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
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- 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
indicated on the valve itself. Avoid the
formation of steam or overheated water.
IMPORTANT: When the temperature of the
liquid is close to the maximum value, the outside
temperature of the valve body is only slightly
inferior. Therefore, take care in case of contact
with the hot surfaces.
4.5- 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.
4.6- IMPORTANT: Do not obstruct the outlet
port for any reason. To convey the water, use a
flexible hose fitted on the hose holder and
locked by means of a clamp. Always release in
the atmosphere. Failure to comply with these
instructions will result in a reduced safety of the
system.
4.7- To fix the valve, manually screw the R3/8" tapered
thread fitting, then apply another 2-3 turns by means of a
spanner to tighten it completely. If necessary, a proper
sealant can be used in order to ensure the thread seal.
wear; furthermore, this
4.8- Should the relief valve open, turn off the system and
find out what is the cause of the pressure increase.
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- Any maintenance and/or repair must be carried out by
authorized staff only.
5.2- We suggest you check, at least every 2
years or after reaching 500 working hours of
the system, that the valve opens correctly in
order to verify the correspondence with the
setting pressure.
5.3- 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

IMPORTANT: 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
might
