CKD PPX Series - Installation and Adjustment Precautions; Installation Warnings and Piping Guidelines; Torque Specifications for Connections

Precautions
PPX
Series
Apply a 12mm spanner (14mm for PPX-6G type)
onthepressureporthexagonheadsectiontox,
then apply tightening torque 9.8N·m or less if a
commercially available joint is connected to the
pressure port. A joint or
the pressure port section
could be broken if too much
torque is applied.
Use seal tape to connect
joints and prevent air leak.
Installation & Adjustment
Please be careful when unpacking, as piping port is
degreased and cleaned. (PPX-P12)

WARNING
Avoid incorrect connection.
An incorrect connection may cause a fatal error not only to
this product but also peripheral devices.
DC power not insulated from AC primary side may
damage the product and power, so an electric
shock could occur.
Do not use the product in this case.
If a commercially available switching regulator
is used for power, ground a frame ground (F.G.)
terminal of power.
CAUTION
Do not use the product where the product is exposed to
direct-sunlight, or may come in contact with water or oil.
Avoid use in high steam and dirt environments.
Care must be taken to avoid product contact with organic
solvents such as thinner, water, oil and fat.
Do not put wire, etc. into the pressure port, or diaphragm
may be damaged preventing a normal operation.
Performance could not be guaranteed in strong
electromagneticeld.
Flash air pipe connected to sensors before
connecting. Prevent pipe from catching tips of
sealing tape when piping.
Apply adequate torque when connecting pipes.
To prevent air leakage and screw damage.
