Note
Kit includes parts from 10-1 to 10-5.
Material: NBR
Note) When changing parts, follow the instruction manual.
Do not disassemble other parts.
Construction
1. Operate this product in an area in which the air
pressure does not exceed 1.6 MPa.
If this value is exceeded, 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 continue to be discharged from
the drainage discharge port.
3. Keep the compressed air temperature and the ambient
temperature of the location in which this product is installed
within the range of 5 to 60°C. Exceeding this range could lead
to failure or malfunction.
4. Avoid operating this product in an area in which
corrosive gases, flammable gases or organic
solvents are contained in the compressed air or in
the surrounding air.
Caution
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 allow for maintenance.
3. To place this product near the air compressor, 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 to ensure
proper flow-in of drain. (Ball valve piping set is available as
optional accessory.)
5. When not draining sufficiently, adjust the open angle of its
bleed valve to lower the pressure inside the case, so that drain-
age will run through easily.
Caution
1. The maximum dischargeable drainage rate is 400
cc/min.
If the product is operated in excess of this value, there is a risk
of causing the drainage to flow over to the outlet side.
Caution
1. Use piping of 1/2B bore size or larger for drain inlet
and allow for unobstructed flow-in for drain.
2. Drain line should be 8 mm or more in diameter and less than
10 m in length. Do not make any upward angles in drain line.
Be sure to secure exhaust port piping since drain is under
pressure.

Caution on Design Mounting
Selection
Piping
1. Check drain condition periodically (more than
once a day).
Then push flushing button to open exhaust valve.
2. Pilot air is exhausted from the exhaust port indicated in the
“Dimensions” section.
Do not cover this exhaust port.
Clean exhaust port so that port is not blocked by dust, etc.
3. When solid foreign objects exceeding 1 mm comes in, the
main valve may become blocked. After recovering the internal
pressure of this product to 0 MPa (atmospheric pressure), re-
move the hexagon socket head bolt (M6) from the body part
and wash inside with water to remove foreign solid particles
blocking the main valve.
4. While operating, there may be cases where drainage will not
easily enter this product. In such a case, adjust the open an-
gle of its bleed valve to lower the pressure a bit inside the
bowl, so that drainage will run through easily.
