Specific Product Precautions 1

Be sure to read this before handling
Operating Environment
1. Do not use in an atmosphere having corrosive gases,
chemicals, sea water, water, water steam, or where
there is direct contact with any of these.
2. Products compliant with IP67 enclosures (based on
IEC60529) are protected against dust and water,
however, these products cannot be used in water. If
using in an environment that is exposed to water
and dust splashes, take measures such as using a
protective cover.
3. When using built-in silencer type manifold with an
IP67 enclosure, keep the exhaust port of the
silencer from coming in direct contact with water or
other liquids.
4. The metal seal valve is provided with a hole to
discharge the pilot EXH. When using in
atmospheres containing water and dust, mount it
horizontally.
Valve Mounting
Mount it so that there is no slippage or deformation in
gaskets, and tighten with the tightening torque as shown
below.
Manual Override
Regardless of an electric signal for the valve, the manual
override is used for switching the main valve. Connected
actuator is started by manual operation. Use the manual
override after confirming that there is no danger.
■
Non-locking push type
Push down on the manual
override button until it stops.
■
Push-turn locking slotted type [Type D]
Push down on the manual override with a small flat
head screwdriver until it stops. Turn it clockwise by
90° to lock it. Turn it counterclockwise to release it.
If it is not turned, it can be operated the same way
as the non-locking type.
■
Push-turn locking lever type [Type E]
Push down on the manual override by finger until it
stops, and then turn it 60° clockwise. The manual
override is then locked.
To release it, turn it
counterclockwise.
If it is not turned,
it can be operated
the same way
as the non-locking type.
Carefully check the manual override
projection amount.
Max. (at OFF): 3.7 mm
Do not apply excessive torque when turning the manual
override.[0.1 N·m] When locking the manual override, be
sure to push it down before turning. Turning without first
pushing it down can cause damage to the manual
override and other trouble such as air leakage, etc.
