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 failure, 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.

<Before Installation>
Confirm the supply voltage to conform with the voltage marked at the coil
label on the housing cover.
Be careful to select a refigerant oil if viscosity of the oil exceeds 50/s
as it might cause failure of solenoid valve.

Do not carry the valve with holding the lead wire only as it may
cause coil burn-out.
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.
Use a mesh strainer (80 to 100 mesh)at the valve inlet.
Mounting position should be in the following range.
(The coil should always direct upward or horizontal.)
Grounding is required at a suitable position on the unit.
ﾟ
Valve Body
<Installation>
When installing the solenoid valve, be sure the arrow embossed on the valve body
points the direction of refrigerant flow.(Be sure to correctly locate outlet and inlet side.)
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.
When brazing the joints, the valve body should be kept cool by wet rags in order not to heat up the valve body in
excess of 120℃(Do not direct the flame to the valve body.)
When brazing, valve inside should be filled with inactive gas(N or CO )to prevent generation of scale.
Special attention is required not to apply excessive force of compression, tension or torsion against the
valve body as it may cause malfunction.
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 : 3N･m{30･cm}〔IEV-B1505DX,B2007DX=2N・m{20・㎝}〕
<Operation>
When removing the solenoid coil from the valve body, be sure to cut out the power supply as the coil
may burn.
Before removing the solenoid coil from the valve body, be sure to cut the power supply. If energizing the coil
itself while it is not assembled into the valve body, the coil may cause burn-out.
