Handling instructions and Precautions (FRZB Filter Regulators)
❼
Note
If liquid sealant gets on the polycarbonate parts, it may
damage them.
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).
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.
●
Usable medium
1.
Use clean air (filtered to below 40 μm) for the medium. Contact
the nearest Koganei sales office or overseas department if you
are considering using something other than clean air.
2.
Avoid using air that contains too much water and/or fluids.
3.
If air that contains water and/or fluids is used, or if it is possible
that they may be mixed in with the air being used, we recom-
mend using the iB-Cyclone to reliably remove water and fluids.
4.
Do not use the product if the medium being used is prone to
extreme pulsating or surging.
●
Medium and operating environment
1.
The temperature of the medium and the ambient environment
must be within the range in the specifications.
●
Operating environment
1.
Do not use the product in locations that are subject to direct
sunlight (ultraviolet rays); locations with high humidity and tem-
perature, dust, salt, or iron powder.
2.
Cover the unit when using it in locations where it might be sub-
ject to excessive dust, dripping water, dripping oil, etc.
3.
Do not use the product in environments subject to external
vibration or impact.
2.
Use a device, such as a freeze-type air dryer or after cooler, to
lower the dew-point temperature of the medium to below the
ambient temperature so condensation or frost does not occur
in the secondary pipes.
3.
Do not use medium in the product or use the product in an
environment that includes corrosive components such as
organic solvents, phosphate ester type hydraulic oil, sulfur diox-
ide, chlorine gas, freon gas, ozone, acids, alkaline, etc.
4.
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 3, 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
for details.
Medium and operating environment
Note
Using the product in an environment that is outside the
specified temperature or with medium 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
Contact a Koganei sales office or overseas department if
you are considering using something other than air.
Note
Using air that contains too much water and/or fluids will
cause the product's functions to stop after a short period
and will reduce the product performance and service life.
Note
If you use an iB-Cyclone, install an FRZ series filter
regulator (without water and fluids removal functions) on
the secondary side.
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.
Note
If condensation or frost forms in the product, it may get into
the secondary side.
Note
Using the product in an environment or with medium that is
specified in the above item 3 will cause the product's
functions to stop after a short period and will reduce the
product performance and service life.
Note
External vibrations or shocks may result in damage to
component parts.

Method of use
Read the Handling Instructions and Precautions for each product
for instructions on correct usage (Filter regulator page
❽
to
,
and
□
1.181 in. integrated pressure gauge page
).
●
Maintenance (maintenance inspection)
1.
Performance and functions may decrease as the pneumatic
equipment ages. Always conduct daily inspections of the pneu-
matic equipment, and confirm that all requisite system functions
are satisfied, to prevent accidents from happening.
2.
Read the Handling Instructions and Precautions for instructions
on maintenance and replacing maintenance parts (Filter regu-
lator page
to
).
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
and reassembled.
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 in the same way leave 1.5
to 2 threads uncovered.
Leave 2 threads open

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