PREFACE
Failure to read and follow all instructions carefully before installing or operating this solenoid valve
could cause personal injury and/or property damage. Save these instructions for future use.
NOTE FOR SAFETY
Warning
・When removing the solenoid coil from the valve body, be sure to cut out the power supply
as the coil may burn.
・Do not apply the different voltage from the voltage marked on the coil label.
It may cause burning or failure.
・While power is on, do not touch the housing cover as personal injury may be caused.(Coil heats up to 90℃)
・Do not apply excessive force and/or any impact to the coil as it may cause valve, burn-out and leakage
trouble due to deformation.
・Do not heat up the solenoid coil as the coil might be burn-out.
・Do not put any inflammable thing around the coil as it could catch fire due to the coil heat.

INSTALLATION
＜Before Installation＞
・Ensure the supply voltage to conform with the electrical ratings specified on coil cover
or coil housing.
・Use the refrigerant oil having a viscosity within the working range of
the [pressure difference - fluid viscosity] specified in the specifications.
If it is used outside the working range, an operation failure occurs.
Be careful with the selection of the oil.
It causes the disconnection.
・Do not carry the valve with the lead wire.
・Be careful to scratch flared part and/or brazing point as it might cause leakage trouble.
・Remove any foreign material or dust in the pipe as it may cause failure of the
solenoid valve.
・If the solenoid valve is not equipped with any strainer, mount a strainer
(80 to 100 mesh) on the inlet side.
・Mounting position should be in the following range.
・Install the space for the maintenance work above the coil.
・Earthing is required at a suitable position on the unit.

used by downward.

＜Installation＞
・When installing the solenoid valve, confirm the arrow shown in the valve body in the direction of the flow.
(Be sure to correctly locate outlet and inlet side.)
・If there is a reduced diameter part just in front of the solenoid valve, there is a possibility that operation become unstable.
In that case, please make sure that the entire system functions normally.
・Special attention is required not to apply back pressure. Inner parts of valve may be deformed and may cause leakage trouble.
・Do not install a check valve at the inlet side as it may cause liquid sealing condition on the pipe inside and may cause
damage due to excessive pressure.
・Make sure to fix the valve body and piping firmly. It may cause to be damaged the connection part by piping vibration.
・Conduct airtight inspection after piping work.
・When brazing connections, maintain the temperature below 120℃ at the valve body by using wet clothe or so.
Also prevent the valve body from direct flame during brazing work.
・When brazing, valve inside should be filled with inactive gas (N and CO , etc.) to prevent generation of scale.
・Be sure to firmly tighten a flare nut.
The proper tightening torque is as follows.
It will be recommended to use the proper size spanner for
tightening flare nuts.
・When using a monkey wrench, select a proper size wrench.
Do not contact the wrench to the coil housing.
・When tightening flare connection, hold the square
part of connection on the piping work side,
with another wrench.
・When tightening flare connection, do not hold coil
with hand, or contact the wrench to the coil part.
・Do not apply excessive force to any other part than
connection part, or it may cause to be occurred
operation failure by the coil housing,
plunger tube, valve body etc. are damaged.
・Hold square part and flare nut firmly with wrench.

・Do not add abnormal power of compression, the pull, and the twist to the main body. It causes the failure.
・Prevent moisture inside piping. It may cause to be operation failure by icing and rust.
・After putting the solenoid coil to the valve body and/or changing the coil direction, be sure to tighten the screw firmly.
Proper tightening torque : 2 N･m
・Loosen the lead wire so that tensility should not add to the lead wire of the coil, when wiring to the coil.
・The protection grade of the connector type coil has been confirmed by our company based on the IEC standard 60529
testing method after mounting an optional socket normally. Confirm the protective performance according to the actual
working environments and conditions of use in advance.
・When you use the optional socket, please make a connection to the socket with a 3-conductor sheathed cable.
(outer diameter of 6～8φ)
・Fasten the mounting screws (M3) of the socket with the torque of 0.4 ～ 0.5N・m.
＜Operation＞
・Before removing the solenoid coil from the valve body, be sure to cut the power supply. If energizing the coil itself while it
2.5 3.6
is not assembled into the valve body, the coil may cause burn-out.
MAINTENANCE/INSPECTION
・In case of disassembling or inspection, please contact Saginomiya.
・Before making a maintenance or inspection for the valve, be sure to cut the power supply.
OPERATION CHECK
・Install the product correctly and then check its operation to confirm correct function of the whole system.
