Handling instructions and Precautions

❼

●

Attaching steel pipes and fittings

If steel pipes and fittings are attached to the threaded sections of
the aluminum die-cast parts of the product, tighten them to the
torque recommended in our standards.

NOTE

Tightening with excessive torque may damage the product or
injure workers or operators.

Preventing contamination by foreign matter

1. Remove all foreign matter, such as metal chips, cutting oil, or

dirt, from inside pipes with an air blower (flushing) and thor-
ough washing before fitting the pipes.

2. Do not allow foreign matter, such as metal chips, or sealing tape

from the piping threads, to get into the pipes when fitting the pipes.

NOTE

Foreign matter entering the piping may damage the product
or reduce its performance and service life.

NOTE

Use a tightening torque of 2.21 to 3.69 ft

•

lbf if the various pressure

gauges are mounted on the NPT1/4 pressure port plate.

NOTE

If a muffler or something is attached to the 3 (R) port of the residual
exhaust valve, tighten it to 1.33 to 1.63 ft

•

lbf.

NOTE

If the sealing tape or sealant gets on the lip of pipes and
fittings, bits of it may get into the pipes and cause air leaks.

NOTE

If liquid sealant gets on the polycarbonate parts, it may
damage them.

3. Wrap the sealing tape in the direction as shown in the diagram

below leaving 1.5 to 2 threads uncovered. When using liquid sealant,
apply a suitable amount and leave 1.5 to 2.0 threads uncovered.

4. If you are using liquid sealant, do not get it on the polycarbon-

ate parts (the bowl of the filter regulator and the front cover of
the pressure gauge).

Medium and operating environment

●

Medium and operating environment

1. The temperature of the medium and the ambient environment

must be within the range in the specifications.

2. Do not use media in the product or use the product in an environ-

ment that includes corrosive fluids such as organic solvents, phos-
phate ester type hydraulic oil, sulfur dioxide, chlorine gas, flon gas,
ozone, acids, alkaline, etc.

3. The bowl and the front cover of the pressure gauge of the filter

regulator are polycarbonate. This product cannot be used in
environments with the gases and fluids in item 2, nor thread-
locking adhesive, leak detection fluid, hot water or where it
may be exposed to them. This product also cannot be used in
direct ultra-violet light. See page

⓰

for details.

NOTE

Using the product in an environment that is outside the specified
temperature or with media that is outside the specified
temperature will cause the product's functions to stop after a short
period and will reduce the product performance and service life.

NOTE

Using the product in an environment or with media that is specified
in the above item 2 will cause the product's functions to stop after
a short period and will reduce the product performance and
service life.

●

Media

1. Use clean air (through 5

m or smaller filter) for the supply medium.

Contact the nearest Koganei sales office or overseas department if
you are considering using something other than cleaned air.

2. Cannot use air that contains water and fluids.

3. If air that contains water and fluids is used, or if it is possible

that they may be mixed in with the air being used, the water
and fluids must be removed completely by installing a water
and fluids removal device (such as the iB-Cyclone*) on the pri-
mary side.

*See the back of the catalog.

4. Avoid using media that is prone to extreme pulsating or surging.

NOTE

Using air that contains water and fluids will cause the
product's functions to stop after a short period and will
reduce the product performance and service life.

NOTE

Medium prone to extreme pulsating or surges will cause the
product's functions to stop after a short period and will
reduce the product performance and service life.

4. Avoid piping that is rigid, such as steel piping, if vibrations are

transmitted. Use flexible tubes so that the product is not sub-
ject to the vibrations.

●

Operating environment

1. Do not use the product in locations that are subject to direct

sunlight (ultraviolet rays); locations with high humidity and
temperature, dust, salt, or iron powder.

2. Cover the unit when using it in locations where it might be

subject to excessive dust, dripping water, dripping oil, etc.

3. Do not use the product in environments subject to external

vibration or impact.

NOTE

External vibrations or shocks may result in damage to
component parts.

Maintenance (maintenance inspection)

1. Performance and functions may decrease as the pneumatic

equipment ages. Always conduct daily inspections of the
pneumatic equipment, and confirm that all requisite system
functions are satisfied, to prevent accidents from happening.

2. Read the "Handling Instructions and Precautions" for instruc-

tions on correctly doing maintenance and replacing maintenance
parts (Filter regulator and regulators page

⓫

and page

⓬

3. The product must be disassembled and reassembled to use

the seal kit.

Operation and maintenance inspections

NOTE

The product is no longer under warranty if it is disassembled
or reassembled.
