NOTE FOR SAFETY
WARNING
This valve is designed and manufactured for refrigerant control in refrigeration,
and air conditioning. Do not use this valve for any other purpose.
Do not use this valve in a system where impact pressure such as liquid hammer
is applied to this valve. It may cause malfunction or fluid leakage.
Select a solenoid valve that matches the size of this valve.
If an oversized solenoid valve is installed, excessive impact pressure
will be applied to this valve, causing it to break.
The voltage indicated on the label and the output voltage of the controller must match.
Applying a voltage other than that specified may cause the coil to burn out (smoke or fire)
or malfunction.For the output voltage of our controllers, refer to the controller's
instruction manual.
Do not touch the coil when the power is on. It may become hot and may cause burns.
Do not touch this valve at low temperatures. The touched part may not come off and
you may get burned.
Do not drop or otherwise subject this valve to impact or large loads. Also, do not
ride on this valve. Doing so may cause coil burnout (smoking or ignition), malfunction,
or fluid leakage.
Do not keep the coil warm. Doing so may cause coil burnout (smoking or ignition).
Do not place flammable materials around the coil. The heat generated by the coil may cause
a similar fire.
Caution
A separate controller is required to operate this valve. Use this controller together with
our pulse converter (recommended sampling time: 10 seconds). Also, be sure to read
the instruction manual for this controller.
If you do not use our controller, please contact us for the excitation method, etc. before
manufacturing. Use of an incompatible controller may result in malfunction.
Loose or miswired terminals not only prevent correct control, but also cause malfunctions.
