THIS DOCUMENT PROVIDES THE INSTRUCTIONS FOR
THE INSTALLATION, USE AND MAINTENANCE OF THE
VALVE, THEREFORE IT IS AN INTEGRAL PART OF
THE VALVE ITSELF AND MUST BE READ CAREFULLY
BEFORE ANY USE AND KEPT WITH CARE.
STRICTLY
COMPLY
CONTAINED IN THIS DOCUMENT IN VIEW OF A SAFE
AND EFFECTIVE USE OF THE VALVE.
FAILURE TO COMPLY WITH THESE INSTRUCTIONS
MIGHT CAUSE EARLY FAULTS AND RESULT IN
SITUATIONS OF DANGER, IN ADDITION TO VOIDING
ANY WARRANTY.
1- GENERAL INFORMATION
1.1- The R1/400 – R1/600 pressure regulator is a
manually-adjustable,
pressure-operated
according to its setting, limits the pump/system pressure by
conveying the excess of water to the by-pass.
Moreover, when the outlet flow is blocked, this device totally
releases the flow, thus keeping the pump/system at the
adjusted pressure.
1.2- Since the R1/400 – R1/600 valve is used in connection
with a high pressure water pump/system, which shall be
called hereafter only "system", installation and use must be
suited to the type of system used and comply with the
safety Regulations in force in the Country where the valve is
used.
1.3- Before using the valve, make sure that the system the
valve is used with is certified to comply with the relevant
Directives and/or Regulations.
1.4- Before installing and using the valve for the first time,
we suggest you check that it is undamaged and make sure
that the rated features correspond to the required ones. If
this is not the case, do not use the valve and contact the
after-sales service of Interpump Group for information.
1.5- In order to install the valve correctly, follow the
instructions for the water inlet and by-pass connections, as
stated in this instruction manual and/or on the valve itself.

2- INSTRUCTIONS FOR PRESSURE SETTING:
2.1- In order to obtain a correct adjustment and
consequently a proper functioning of the valve, always
make sure that, when working at the maximum pressure,
the valve by-pass keeps releasing a quantity of water
equal to 5% of the total flow-rate. In case the flow-rate at
the by-pass is close to zero or exceeds 15% of the
maximum flow-rate, this could cause faults, early wear and
result in situations of danger.
The positions mentioned in the following instructions refer
to those shown in the spare parts catalogue (page 4).
2.2- Connect the valve to the water system and follow
these steps:
2.2.1- Unloose the nut pos. 19.
2.2.2- Unscrew the nut pos. 22 in order to completely
which,
release the springs.
2.2.3- Open the gun or the water control device and start
the system. Make sure that the air contained in it is fully
ejected.
2.2.4- Keeping the gun or the water control device open,
start adjusting the pressure by screwing down the nut
pos.22. Alternate the adjusting operations with a few
openings and closings of the gun or of the control device.
When the desired pressure has been reached, open and
close the gun/control device a few times again in order to
stabilize the various components (seals, springs etc.).
Check the pressure value again and correct if necessary.
2.2.5- Screw down the lower nut pos. 19 up to contact and
lock it on the body.
2.2.6- In order to obtain working pressures lower than the
maximum set pressure, unscrew the nut pos. 22.
In case of doubts, do not hesitate to contact
the after-sales service of Interpump Group.
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.
