How to assemble the module

Assembly precautions

<div class="ico_caution">When assembling, pay attention to the direction of fluid supply. (supply side → output side)</div>

• Modular basic order : filter → regulator → lubricator
• When assembling multiple filters, assemble them in order from the largest to the smallest.
  e.g. KAF(5 μm) → KAFM(0.3 μm) → KAFU(0.01 μm)

1. Fasten the seal in the seal fastening groove between the products to be assembled or by using a spacer.
   Seal fastening groove : 301 body
   Spacer attach : 101, 201, 401, 601 body
2. After positioning both products, fix the front and rear module brackets.
3. Assemble the bracket fixing bolts from the front to the rear side of the bracket.

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.
• Install the bowl vertically with the bowl facing down.
• For sets of 3 or more, we recommend fixing the bottom of the bracket.
• Brackets cannot be mounted on both sides of the T-type bracket and pressure switch.

Pneumatic piping

1. Check the flow direction and place the product. Check the IN and OUT or arrows on the product body.
2. 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.
3. 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.
• Min. Operating pressure required for auto drain type is 0.15MPa.

Disassembly

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

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

Regulator pressure adjustment

Precautions before pressure adjustment

• Set the pressure while checking the inlet pressure and outlet pressure.
• Set the set pressure 0.1 MPa or lower than the inlet pressure before use.
• Operate the pressure control handle manually. Use of tools, etc. may cause damage to the handle.
• If the pressure difference between the supply side and the output side is large, pulsation may occur.
  In this case, use with a small pressure difference between the supply side and the output side.
• When releasing the pressure (turn counterclockwise), check the pressure drop at the outlet or gauge, and operate the handle only until the pressure becomes “0”.
  If you turn the handle too far, the handle may lock.

How to adjust the pressure

<div class="image dark-mode-images manual-half-img"><img src="https://cdn.prod.website-files.com/6577e4ddb18c5363e98a478a/65c094ddab3fd8f47c1e0a3c_KAR__regulation_dark__en.png"></div>

1. Pull the handle to release the lock. (a blue band appears under the handle.)
2. Turn the handle clockwise to increase the outlet pressure to the desired set pressure.
   At a pressure lower than the target set pressure, gradually increase the pressure to reach the desired set pressure.
3. To lock the handle, press down the pressure control handle. (blue band under is hidden.)

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

<div class="image dark-mode-images manual-half-img"><img src="https://cdn.prod.website-files.com/6577e4ddb18c5363e98a478a/65c0710e3e490e7d101c1063_FilterDrain_drak__en.png"></div>

• 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.

Filter replacement

• When to Replace the Filter Element
• ~~Replace the filter element after 2 years of use or when the outlet pressure drop exceeds 0.1MPa.
• ~~Replace when the green part of the differential pressure indicator turns completely red.

Oil adjustment

• When injecting oilthrough an open bowl instead of a refueling port, remove the residual pressureinside and then disassemble the bowl.
• Perform adjustment ofthe oil amount-adjusting valve manually. Excessive external impact due to theuse of tools, etc. may cause damage.
• When you rotate to the -or + side of a regulating valve and reach the end, it stops to prevent anyfurther adjustment. At this time, take care not to damage the regulating valveby attempting to rotate it further with excessive force.
• Use clean and pure oil.Failure to do so may cause inadequate loading or clogging.
• Inject oil only up tothe maximum oil level of the case.

Cleaning

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