Installation and disassembly

Precautions before installation

<div class="ico_danger">Installation and disassembly of a pressurized product may cause personal injury and/or property damage.</div>

<div class="ico_danger ico_2ndline">Before installation, be sure to release the pressure inside the product and piping.</div>

Ensure free space around the product for maintenance and safe operation.
Do not install in a location with high humidity or temperature. Doing so may cause performance degradation or malfunction.
Avoid dropping and external impacts when transporting and installing the product.
Connect the pneumatic pipe after completing the installation.
When connecting only the pneumatic pipe, without a separate mounting device, consider installing a separate pipe support to prevent excessive moment load or vibration on the pipe side. Otherwise, a malfunction or damage may occur.
Before installing the piping, flush or clean the piping sufficiently to remove any foreign substances. Even when fastening piping or fittings, make sure that chips from the piping screws or sealing material do not move into the machine. These may cause malfunction.
In case a lubricator is used for the lubrication of an air cylinder, etc., install a deoiler in front of the lubricator.
Be sure to install the deoiler “immediately before” the final equipment. If the piping after a deoiler is long, condensation may occur due to the temperature difference between the inside and outside of the pipe.
To prevent the clogging of a drain valve, installing a common filter just in front of a deoiler is recommended.

Pneumatic piping

Check the flow direction and place the product. Check the IN and OUT or arrows on the product body.
Fasten the threaded part of the pipe or fitting to the pneumatic port.
- Hold the female thread side and apply the proper torque.
- Insufficient tightening torque may lead to loosening or an improper seal. Excessive tightening torque may cause damage to screws, etc.
After completely sealing the pneumatic port, connect the pneumatic tube.

Drain piping

Install vertically with the drain outlet facing down. It cannot be used in a lateral or upward orientation.
For auto drain discharge piping, the auto drain kits (AD201F, AD301N, AD401N) use a ∅6 outer diameter (∅4 inner diameter) tube, and the length must be within 5 meters.

Disassembly

<div class="ico_danger">Before disassembly, be sure to release the pressure inside the product and pipe.</div>

Exhaust air from the entire system and product.
Press and release the lock on the pipe or fitting, then pull out the hose line.
Loosen the fitting on the connecting flange and turn it out.

‍

Maintenance

Air source

Please use clean air.
If the compressed air contains chemicals, organic solvents, synthetic oil, or corrosive gas, it may cause damage to parts or malfunction.
Air containing a large amount of moisture or foreign substances can cause malfunction, so install an air dryer or an after cooler on the inlet side of the product.

Maintenance and inspection

Regularly inspect the bowl for contamination, cracks, damage, and other deterioration. Use a neutral detergent for cleaning. If the contamination is severe, replacement is recommended.
In case of cracks, damage, or other deterioration, replace it.

Drain release

Open and close the drain valve manually. Use of tools may cause damage.
Release the drain before the level of the drain reaches the baffle.
~~Manual drain : turn the drain valve handle counterclockwise to drain.
~~Float-type auto drain : when the water level in the drain reaches the appropriate level, it is automatically discharged.
You can force a discharge by pushing the lower outlet.

Cleaning

Clean the exterior of the product periodically with a soft cloth.
Allowable detergents : soapy water (maximum 60°C), neutral detergent (without aromatic compounds)

Failures and measures

Breakage

Damage to the bowl or drain parts

In case corrosive gas is contained in compressed air

- Remove the cause of gas mixing, replace the damaged parts.

‍

In case parts are damaged due to external impact

- Remove the cause of external impact, replace the damaged parts.

Drain

Drain discharge not possible

In case the drain valve outlet is clogged with solid foreign matter, etc.

- Replace the bowl assembly.

Flow

Excessive or unstable pressure drop

In case flow consumption at exit exceeds the product’s specifications

- Replace it with a product with greater flow.
