No.
Caution Operation
(1) Do not use a precision regulator outside the range of its specifications as this can
cause failure. (Refer to specifications.)
(2) When mounting is performed, make connections while confirming port indications.
(3) If a directional switching valve (solenoid valve, mechanical valve, etc. ) is mounted
on the supply side of the regulator and repeatedly switched ON and OFF, wear of
the nozzle/flapper section will be accelerated and a discrepancy in the setting value
may occur. Therefore, avoid using a directional switching valve on the supply side.
In the event a directional switching valve will be used, install it on the output side
of the regulator.
(4) Air/oxygen is normally discharged from the bleed port (the hole on the side of the
body's mid-section). This is a necessary consumption of air based on the
construction of the precision regulator, and is not an abnormality.
(5) Be sure to tighten the lock nut after pressure adjustment.
Caution Air supply
(1) If the supply pressure line contains drainage or dirt, etc., the fixed throttle can
become clogged leading to malfunction, and therefore, in addition to an air filter
(SMC Series AF) be sure to use a mist separator (SMC Series AM, AFM). Refer to
SMC's "Compressed Air Cleaning Systems" catalog regarding air quality.
(2) Never use a lubricator on the supply side of the regulator, as this will positively
cause the fixed throttle to become clogged and lead to malfunction. If lubrication is
required for terminal devices, connect a lubricator on the output side of the
regulator.
Caution
Piping
(1) Preparation before piping
Before piping is connected, it should be thoroughly blown out with air (flushing) or
washed to remove cutting chips, cutting oil and other debris from inside the pipe.
(2) Wrapping of pipe tape
When connecting pipes and fittings, etc., be sure that cutting chips from the pipe
threads and sealing material do not get inside. Further, when pipe tape is used,
leave 1.5 to 2 thread ridges exposed at the end of the pipe/fitting.
