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 KR automatic pressure regulator is a manually-
adjustable, pressure-operated device which, 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 – and keeps under pressure the portion of the
system following the valve, while it reduces the pressure in the
portion of the system preceding the valve.
1.2- Since the KR 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, outlet and by-pass connections, as stated in
this instruction manual and/or on the valve itself.
2- PACKAGE
2.1- Packages must be handled in compliance with the
instructions stated on the packages themselves and/or provided
by the manufacturer.
2.2- In case the valve is not used immediately, it must be stored
in its integral package and placed in areas which are not
exposed to the weather and protected from excessive humidity
and from direct sunlight. Moreover, it is advisable to place
wooden pallets or other types of pallets between the package
and the floor, in order to prevent the direct contact with the
ground.

3- INSTRUCTIONS FOR MAX. PRESSURE SETTING:
3.1- 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 exploded view (page 3).
3.2- Fit the valve to the pump head (follow the "ASSEMBLY"
instructions), then connect the pump to the water system and
follow these steps:
3.2.1- Fully screw down the knob pos. 1.
3.2.2- Unloose the nut pos. 23 and unscrew the screw pos. 22
in order to completely release the spring.
3.2.3- Open the gun or the water control device and start the
system. Make sure that the air contained in it is fully ejected.
3.2.4- Keeping the gun or the water control device open, start
adjusting the pressure by screwing down the screw 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.
3.2.5- Lock the screw pos. 22 by tightening the nut pos. 23.
3.2.6- By adjusting the knob pos. 1 it is possible to obtain the
whole range of intermediate pressures between the maximum
pressure that has just been set and the minimum pressure.
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.
