The ARKA Core Multi-Filter MF4000 is a multifunctional filter made of robust and food-safe plastic that can be filled with various filter materials (including resin/mixed bed resin, absorbers, activated carbon and much more). The MF4000 is ideally suited as a resin filter after an osmosis installation, but can also be used universally. This is made possible on the one hand by the 1" built-in water-neutral plastic screw thread and the reduction from 1" to 3/4" and on the other hand by the ¾" to ¼" connection pieces that are used in the The filter is pressure-resistant up to 28 bar and is characterized by a double O-ring seal characterized by maximum tightness.

A 4000 ml filter cartridge is supplied in the 20 x 4.5 inch filter housing. Fine filters are installed on both sides of the inner filter cartridge. These ensure that suspended matter does not end up in the inner filter or parts of the filter material of the inner filter. The supplied inner filter cartridge can be refilled, but can also be replaced with inner cartridges of comparable dimensions.

Installation:

• Mount the supplied wall bracket in the desired location and screw the MF4000 onto the wall bracket.
• Now remove the main body of the MF4000 using the supplied filter cartridge wrench.
• Remove the cartridge from the main body and open it with the top screw cap.
• Fill the inner cartridge with the filter material, screw the lid back on and replace the cartridge in the filter housing.
• Screw the basic body onto the filter cover.
• Use the filter cartridge wrench for this.
• Connect the water source and a drain hose to the designated water inlets (IN) and water outlets (OUT).
• Make sure the hoses are connected correctly and securely.

Watch out!

• The multifilter must be securely fastened to prevent it from falling over! Therefore, use the supplied wall bracket!
• The maximum pressure resistance of 28 bar must not be exceeded!
• Bleed the housing by pressing and holding the red vent button (on top of the filter cover) until water comes out of the housing.
• The manufacturer recommends the use of the supplied filter sponges.
• If you want to use the supplied transitions, make sure that the O-ring seals that are also supplied are placed correctly.
• Alternatively, you can often wrap the wire sides with the provided Teflon tape.
• Before using the ¾'' to ¼'' transitions, please note the following: Before installing the hose, remove the blue retaining rings and push the retainer down. Once the hose is connected, replace the retaining rings.
