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 K3 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, thus reducing the pressure throughout the
system.
2- WARNINGS:
2.1- To ensure the tightness of the fittings used to connect the
valve to the system, interpose a metal washer with a rubber ring
or insert an appropriate sealing on the thread and tighten them to
the torque indicated in the table.

2.2- Use guns or other control devices ensuring a perfect seal
when closed. Leakages may compromise the correct functioning
of the valve.
3- INSTRUCTIONS FOR 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- Connect the valve to the water system and follow these
steps:
IMPORTANT: When setting the pressure, comply
with the direction of rotation as stated in the
instruction manual and/or on the valve.
3.3- Unloose the nut pos.13 and fully screw down the
adjustment screw pos. 12 (counter-clockwise rotation) in order
to reduce the pressure to the minimum value.
3.4- Open the gun or the water control device and start the
system. Make sure that the air contained in it is fully ejected.
3.5- Keeping the gun or the water control device open, start
adjusting the pressure by unscrewing the screw pos.12
(clockwise rotation). 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.
3.6- Lock the screw pos. 12 by tightening the nut pos. 13.
3.7- In order to obtain working pressures lower than the
maximum set pressure, unloose the nut pos. 13 and turn the
screw pos. 12 counter-clockwise.
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.
