3. INSTALLATION
3-1. Place of Installation:
Install SEPAREL in accordance with conditions specified in the specification sheet,
●No exposure to direct sunlight
●No physical shock or shaking
●No contact with dust, moisture, corrosive gas, or liquid
●Easy access for maintenance, inspection, repair, and replacement
3-2. Method of Installation:
●Set the vacuum port downward to smoothly purge liquid derived from vapor.
●If you fix SEPAREL with a U-band, make sure not to loosen the fitting. Do not apply too
much pressure when fixing SEPAREL with a U-band as too much pressure may damage
the module. Putting a cushion between SEPAREL and U-band may prevent damage to
the module.
3-3. Connection of the SEPAREL Module:
●Clean pipe/tube before connecting to prevent/remove dust, rust, oil, etc.
●Do not apply too much pressure to the connection.
●Do not shake or shock the SEPAREL module. Shaking or shocking SEPAREL
may damage the module even if it is a light impact.
●Because the housing of the SEPAREL module is composed of PP, polypropylene,
excess pressure to the connector may cause damage to the connecting port. Excess
pressure to connecting port may shave thread and cause resin particles to appear in the
liquid side.
●Do not touch hollow fibers.
●When you add a connector, adjust the insertion depth and not the screw part to touch
hollow fibers. If the screw part touches the hollow fibers, the hollow fibers may become
damaged.
●Depending on the type of connector, recommended conditions of connector insertion
may differ. For detailed conditions, including torque value, contact us.
●The liquid feeding pump is recommended to be placed in front of the SEPAREL module.
●When you uninstall the SEPAREL module, be careful to not damage it.

2) Liquid Out:
●There is a possibility that particles are generated by the SEPARELmodule. To
prevent a problem with such particle occurrence, install a filtration filter behind the
module. The most suitable filtration size depends on your use conditions. For more
details, please contact DIC.
●Note that back pressure to the SEPAREL module should be avoided.
3）Vacuuming:
●Installed vacuum lines must always be facing downwards. If it is pointed upwards,
liquid generated from vapor may block the vacuum line.
●Install a trap to detect leaked liquid and to prevent the vacuum pump from damage
due to vapor and leaked liquid.A trap is also effective in preventing leaked liquid
from feeding into other modules using the same vacuum line.

3. INSTALLATION
1）Liquid In:
●Install security devices, such as apressure reducing valve and/or safety valve,
to make sure that pressure will not be beyond the maximum operating pressure.
●If you use asolenoid valve, select one which dose not cause sudden opening/shutting.
●If you use two modules in parallel, properly measure the liquid flow into both modules
and ensure that liquid flow is equal.
●If impurities and large particles remain in liquid, install afilter in front of the
SEPAREL module.
●Use RO water or higher quality water for the water supply.
▼In the event water of awater quality lower than RO water is used:
①Please ensure the remaining chloride concentration is, ≦1mg/L".
※You can use water with over 1mg/L, but any warranty period will be determined through
consultations between DIC and the customer.
②To stop performance degradation by fouling in the film surface and clogging by
particle debris, please refer to the following table and use apre-filter.
Specifically, since soluble compounds included in well water, abranch and tap water are
easy to penetrate filtration and adhere to the surface of the filtration membrane, please
use water in combination with the recommendations in following table.
If you have any questions, please contact DIC Corporation.

4-1. Open a valve on the outlet side first. Next, open a valve on the inlet side gradually to
make the liquid flow rate and pressure lower than the designated value for actual use
until liquid is filled. Do not flow liquid at a very high flow rate nor at a very high pressure.
Even if it is instantaneous, very high flow rates or pressure may damage hollow fibers
and cause leakage. For efficient removal of remaining air in the liquid area of
SEPARELmodules, filling the liquid with a vacuum is recommended. During the
vacuuming process, check the airtightness of the vacuum line and not the air that
is leaked from pipe, connector, and SEPARELmodule.
4-2. Observe liquid quality, temperature, and pressure specified in the specification sheet.
4-3. Do not flow oxidizing agents, such as highly concentrated chlorine water and ozone
water, strong acids, strong bases, organic solvents, oil, or any other liquid which has
not been confirmed as compatible by DIC. The warranty will not apply if liquid, which
has not been confirmed as compatible by DIC, is used.
4-4. Do not change the flow rate dramatically in order to ensure that the hollow fibers are
not damaged by drastic pressure fluctuations.
4-5. If vacuum pressure is very strong, and conditions are close to a perfect vacuum
situation, stop the vacuum pump when liquid flow has stopped. Strong vacuuming for
an extended period of time without liquid flow may freeze and damage hollow fibers via
vaporization heat and liquid may leak from the damaged hollow fibers.
4-6. Check the items below periodically. If obvious deterioration is found, replace with a
new degassing module .
Item Points to be Checked
Liquid Inlet Pressure Do not exceed maximum pressure specified in the specification sheet.
Liquid Temperature ･Do not exceed the maximum temperature specified in the specification sheet.
･Do not fall below the minimum temperature specified in the specification sheet.
Pressure Drop Significant increase from initial value may be caused by clogging of hollow fiber
or liquid flow path. In this case, replacement or cleaning is necessary.
Drain/Trap
in Vacuum Line Continuous leaking of liquid to the vacuum means the product is reaching the
end of its lifetime and replacement with a new degassing module is necessary.

5-1. Open the leak valve in the vacuum line.After vacuum is released, stop the vacuum
pump.
5-2. Close the valve on the ink inlet side and then close the valve on the liquid outlet side.
5-3. Handling during Shutoff Period:
1) Store under the conditions specified by the specification sheet.
2) If the shutoff period is extensive, remove the SEPARELmodules and store after
cleaning and drying completely. If it is difficult to uninstall the SEPAREL module, fill it
with liquid that is compatible with SEPAREL and close all liquid and vacuum ports
completely. Even liquid that is compatible with degassing module materials can lead
to bacteria generation if it is left in the module during shutoff periods. The
generation of bacteria may have a negative impact on product quality.

Recommended Degree of Vacuum：5kPa(abs) ～10kPa(abs)
= 50mbar(abs) ～100mbar(abs)
※The above pressure is the recommended value when using the module at 15-30℃.
When using the module at temperatures lower than 15℃or higher than 30℃,
please contact DIC for more details.
※The above vacuuming pressure is not suitable for every application. Depending on
applications, composition, and target degassing performance, the most suitable
vacuuming value may be different from the above value.
＜Reference：Saturated Water Vapor Pressure＞
2. For Non-Aqueous Liquid.
Recommended Vacuuming Degree: We recommend setting weaker degrees (higher
in
value) than the recommended saturated vapor pressure of the liquid.
Ex：In cases where saturated vapor pressure is 8kPa(abs), we recommend a weaker vacuum
degree than 10kPa(abs).
As the vacuum pressure degree approaches aperfect vacuum, degassing
performance is improved. However, if the vacuum pressure degree is too strong
yet close to perfect pressure, liquid may evaporate and penetrate through the
membrane.As a result, the composition of liquids may change. Therefore, DIC
recommends following the exact vacuum pressure degree.

Make sure that the liquid feeding pressure at the inlet port is lower than the maximum
pressure value described in the specification sheet.
If the feeding pressure exceeds the maximum value, even momentarily, the hollow fiber may
be damaged and ink may leak into the vacuum line.
※The warranty will not apply in cases where liquid feeding pressure exceeds the maximum
pressure value specified in the specification sheet,
Even if liquid feeding pressure is lower than the specified maximum pressure, an increased
flow rate will cause lesser degassing performance. On the other hand, if the flow rate is too
low, degassing cannot be efficient. Therefore, DIC supplies recommended flow ranges in the
table below.
※The recommended flow range below was calculated when using water. In the case of
high viscosity liquid, a suitable flow range will be more narrow.
