Caution
Environment
(1)Do not use the product in an environment where the product is directly
exposed to corrosive gases, chemicals, salt water or steam.
(2)Do not mount the product in a location where it is subject to strong vibrations
and/or shocks.
(3)Use this vacuum regulator in a location free from dirt since this product
sucks atmosphere all the time.
(4)When the product is directly exposed to sunlight, provide a protective cover.
(5)When heat source is around the product, shut off radiant heat.
Caution
Vacuum Source
(1) This vacuum regulator does not control pressure by connecting with the
exhaust side of the vacuum pump.
(2)Note that ejector should not be used as ”vacuum source” since its flow rate is less
than this vacuum regulator.
Caution
Air
(1) Contact SMC when using the product in applications other than
Compressed air.
(2) Do not use air containing chemicals, synthetic oils with organic solvents,
Salinity and corrosive gases.
Caution
Operation
(1) Connect vacuum pump to the port indicated by “VAC”(shown in upper
Right of the port).
(2) Pressure changes ”atmospheric pressure→vacuum pressure” by turning
the handle clockwise and “vacuum pressure→atmospheric pressure” by
turning the handle counterclockwise.
(3)Pressure cannot be controlled if the air intake hole (hole on the side of the
body) is blocked. Do not block the air intake hole by hand or with an object
during pressure adjustment.
(4)To lock the handle after pressure setting, push the handle until orange
Mark below is hidden and it clicks. To unlock the handle, pull the handle
Until the orange make is seen and it clicks.
(5)Maximum settable vacuum pressure is affected by the atmospheric pressure where
the vacuum regulator is used. Atmospheric pressure varies depending on the
altitude and weather. Actual maximum settable vacuum pressure may not reach the
value in the specification.
(6)When vacuum pump capacity is relatively small or piping ID is small, large
fluctuation of set pressure (variation range in pressure when flowing from
zero) may be the result. In this case, change the vacuum pump or piping
