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 CONTROL SET W2 automatic pressure regulator is
a manually-adjustable,
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 CONTROL SET W2 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 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
which,
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:
3.3- Minimum pressure
3.3.1- Fully unscrew the knob pos. 3 and remove it.
3.3.2- Remove the washer pos. 4 and the spring pos. 5.
3.3.3- Unscrew the nut pos. 6 in order to completely release the
spring pos. 7.
3.3.4- Open the gun or the water control device and start the
system. Make sure that the air contained in it is fully ejected.
3.3.5- 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
gun/control device a few times again in order to stabilize the
pressure.
3.3.6- Fit back the spring pos. 5, the washer pos. 4 and the
knob pos. 3.
