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 W2 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.
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 exploded view (page 3).
2.2- Fit the valve to the pump head (follow the "ASSEMBLY"
instructions), then connect the pump to the water system and
follow these steps:
2.3- Minimum pressure
2.3.1- Fully unscrew the knob pos. 3 and remove it.
2.3.2- Remove the washer pos. 4 and the spring pos. 5.
2.3.3- Unscrew the nut pos. 6 in order to completely release the
spring pos. 7.
2.3.4- Open the gun or the water control device and start the
system. Make sure that the air contained in it is fully ejected.
2.3.5- Keeping the gun or the water control device open, start
adjusting the minimum pressure by screwing down the nut
pos.6. 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

pressure.
2.3.6- Fit back the spring pos. 5, the washer pos. 4 and the knob
pos. 3.
2.4- Maximum pressure
2.4.1- Unloose the nut pos. 1 and unscrew the screw pos. 2
almost completely.
2.4.2- Unscrew the knob pos. 3 in order to completely release the
spring pos. 5.
2.4.3- Open the gun or the water control device and start the
system. Make sure that the air contained in it is fully ejected.
2.4.4- Keeping the gun or the water control device open, start
adjusting the pressure by screwing down the knob 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 etc.). Check the pressure
again and correct if necessary.
2.4.5- Screw down the screw pos. 2 up to end stop and lock it by
tightening the nut pos. 1.
2.4.6- By adjusting the knob pos. 3 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.
3- WARNINGS
3.1- Use guns and/or other control devices ensuring a perfect seal
when closed. Leakages may compromise the correct functioning
of the valve.
3.2- Use guns and/or other control devices ensuring a perfect seal
when closed. Leakages may compromise the correct functioning
of the valve.
