UNPACKING (Section 3)
Bags containing solenoid valves should be opened only
when you are ready to connect the valves to the pipes
immediately afterward.
If bags are opened before the valves are ready to be con-
nected to the pipes, the entry of foreign matter from the
piping ports could cause the solenoid valves to fail or
malfunction.
INSTALLATION (Section 4)
If you have to use the product under conditions that are
different from the specified conditions or if you intend to
use the product for a special application, be sure to con-
sult us about the product specifications before using the
product.
ENVIRONMENT (Section 4.1)
a) In a dusty environment, foreign matter may enter even
through the exhaust port.
The movement of the exhaust valve causes a respiratory
action at the exhaust valve, which may cause inhalation of
foreign matter near the exhaust port. This potential sit-
uation would be worse if the exhaust port is facing up-
ward. Attach a silencer to the exhaust port or have the
exhaust port face downward.
b) Keep the solenoid valve system dry. Take care to
avoid direct contact with dripping water or splashes of
cutting oil.
If the solenoid valve system is wet by a direct contact
with water or cutting oil, an electrical leak or burnt sole-
noid coils may result. Protect the solenoid valve system
by using a cover or by installing it inside a paneled casing.
If the cylinder rod is splashed with cutting oil, the oil may
penetrate through the cylinder into the secondary side
piping of the solenoid valve. This must be prevented to
avoid malfunctions. Consult us for preventive measures.
c) The coils will produce heat.
Particularly if the solenoid valve system is installed in a
control board or if the solenoid coils need to be energized
for a long time, consider providing sufficient ventilation to
release the heat. The coils can get very hot.
d) Do not use the solenoid valve system in an atmos-
phere that includes a corrosive gas or solvent vapors.
Do not use the solenoid valve system in an atmosphere
that includes a corrosive gas such as the sulfur dioxide
gas or in an atmosphere that includes solvent vapors.
e) Vibrations and shocks
Do not subject the solenoid valve system to vibrations
50m/s
2
or stronger or shocks 300m/s
2
or stronger.
