1. Use this product in an area
where the air pressure does not
exceed 1.6 MPa.
If exceeding 1.6 MPa, it could lead to
an accident or malfunction.
2. An air pressure of 0.05 MPa and
an air compressor’s discharge
flow rates higher than 50 l/min
(ANR) are required.
Below these values, the air will be ex-
hausted continuously from the drain
exhaust port.
3. Keep the compressed air and the am-
bient temperature of the location
where this product is installed within
the range of 5 to 60°C. Exceeding this
range could lead to a failure or mal-
function.
4. Avoid using this product in an
area where corrosive gases,
flammable gases or organic sol-
vents are contained in the com-
pressed air or in the surround-
ing air.
Caution
1. The maximum dischargeable
drainage rate is 400 cc/min.
If using this product in excess of this
value, there could be causing the drain
to flow over to the outlet side.
Caution
1. Use piping of 1/2
B
or larger for
drain inlet and avoid riser pip-
ing.
2.
For drain piping, use a pipe whose I.D.
is not less than 8 mm and length not
more than 10 m. Do not make any up-
ward angles in drain line. Be sure to
secure exhaust port piping since drain
is under pressure.
Caution
1. Check drain condition periodi-
cally (more than once a day).
Also, push the flushing button to open
the exhaust valve.
2. Pilot air is exhausted from the exhaust
port indicated in “Dimensions”. Do not
cover this exhaust port. Clean the
exhaust port so that port is not blocked
by dust, etc.
3. When solid foreign objects exceeding 1
mm come in, the main valve may be-
come blocked. After recovering the in-
ternal pressure of this product to 0
MPa (atmospheric pressure), remove
the hexagon socket head cap screw
(M6) from the body part and wash in-
side with water to remove foreign solid
objects blocking the main valve.
4. When using this product, drain may
not easily enter the product. In such a
case, adjust the open angle of its
bleed valve to lower the pressure a bit
inside the bowl so that drain could run
through easily.

Specific Product Precautions
1. Install with “out port” down in a
vertical position.
Inclination from the vertical line should
be less than 5°.
2. Install with at least 200 mm of
free space above the unit to al-
low for maintenance.
3.
To place this product near the air com-
pressor, install in such a way that the
vibrations will not be transmitted.
4. Install a valve to drain inlet so
that maintenance is possible.
Use a ball valve with a bore size of
more than 15 mm. (Ball valve piping
set is available as an accessory (op-
tion).)
Caution
Mounting
5. When not draining sufficiently, open
the bleed valve so that drain could run
through easily.
