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 K1 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.

G 3/8"
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 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.
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 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.
