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 WITH THE INSTRUCTIONS 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 CONTROL SET W3 automatic pressure
regulator is a manually-adjustable, pressure-operated
device which, according
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 CONTROL SET W3 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.
2.3- The package components must be disposed of in
compliance with the relevant laws in force.
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
the
result in situations of danger.
The positions mentioned in the following instructions refer
to those shown in the exploded view (page 4).
3.2- Fit the valve to the pump head.
3.2.1- The valve can be fitted either on the left or on the
right side of the pump head indifferently.
In order to assemble the valve, follow these steps:
- remove the two caps located on the high and low
pressure ports on the side of the pump head on which you
wish to fit the valve
- fix the valve on the pump head by means of the screws
pos. 33 and pos. 35.
3.3- Connect the pump to the water system and follow
these steps:
3.3.1- Remove the yoke pos. 2 by means of a screwdriver.
3.3.2- Take off the knob pos. 1.
3.3.3- Unloose the nut pos. 4 and unscrew the screw pos.
3 in order to completely release the spring.
3.3.4- Screw down the pressure adjuster pos. 5 up to end
stop.
3.3.5- Open the gun or the water control device and start
the system. Make sure that the air contained in it is fully
ejected.
3.3.6- Keeping the gun or the water control device open,
start adjusting the pressure by screwing down the screw
pos.3. Alternate the adjusting operations with a few
openings and closings of the gun or of the control device.
When the maximum 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
