Change the Water Filter to cheaper extern Device.

Water Filter have to be replaced every 6 months. The original Water Filter is expensive. So I decided to short the Filter and placed a cheap Filter outside.

Edit Step 1 Water Filter to Extern  ¶

Edit Step 1 Water Filter to Extern  ¶ 

  • BEFORE DEINSTALLING THE FILTER CUT OFF THE WATER LINE. Lay a Towel in the Fridge. Also cut off AC Mains. This is an opened Waterfilter. Inside is a sort of coal which adsorbs unhealthy particles. It has to be changed every 6 months or less.

Edit Step 2  ¶

Edit Step 2  ¶ 

  • First take out three drawers. The Meat drawer is top, the Vitaminsafe is in the middle and the Freshzone is lowest. Between Meat & Vitaminsafe is a Bottom which is snaped in with clipse. Use a plastictool or a woodpiece to open the clips and remove the bottom. There are no screws.

Edit Step 3  ¶

  • Behind the lowest drawer is an plastic panel, which can easy be pulled off. Now you can see the Water-reservoir for the Water Outlet. Also you can see on the right the hosing for the Waterfilter. There are no screws.

Edit Step 4  ¶

Edit Step 4  ¶ 

  • The Botton above the lowest drawer has a heating foil. Unscrew on the back a PH2 Head screw. Also is a PH2 in front left at the Filter's place. Now carefully lift the Bottom. Take out the Styroporfoam-Element. Then open the Plasticbag which contains the Connector for the Heating. You should cut-off the AC-Mains before unplugging this Connector.

  • Now you can remove the Heating; Top of the Bottom.

  • Open the shorter PH2 Screw to release the LED-Light on the Bottom. That's necessary because with the wires at it you could not pull out the chassis of the Bottom.

  • Now you can pull out the Chassis of the lower Bottom, use a Plastictool for the Clipse. Pull off the holder of the Waterfilter.

Edit Step 5  ¶

Edit Step 5  ¶ 

  • Here you have the a picture of the Filterholder. The Towel soaks the water

  • The Inputhose has 8 mm. The Output has 6,35 mm (1/4"). Lay a small Towel under the Holder.

  • Pull off the hoses. Some Water could come out. Mark the tubes with red and blue tape. So it will be easier to reasemle if a warrranty-check could occur.

Edit Step 6  ¶

Edit Step 6  ¶ 

  • Now you need some plug couplings. Adapter from 6,35 mm (thats 1/4 inch) to 8 mm (thats 5/16 inch), Coupling 6,35 to 6,35 and a piece of hose 6,35. Carefully cut the hose nice and clean with a ahrsp cutter. Now easy click these parts together. Now you have a Bypass for the original Filtermount. :)

Edit Step 8  ¶

Edit Step 8  ¶ 

  • Now put it all together, don't forget the PH2 Screws and you are done.

  • Now you can mount an extren Waterfilter.

  • The first water will be black from the coal. Don't drink it. Also there is now a lots of air in the hose, so the water will flow unregular and cause problems and weird sounds. Give it some time, the problems will solve. :)

Edit Step 9  ¶

Edit Step 9  ¶ 

  • This is an Saw-Cut off the external Filter i've bought. You see the same adsorbing coal like in an original Filter.

  • It costs about 10 Bucks. The Original costs about 80 Bucks. Two Filters are needed every year. So this was a good Decision. Enjoy your clean Water. :)

  • Sorry for my bad english writing. I hope the pictures may help someone.

To reassemble your device, follow these instructions in reverse order.

hello

in order to bypass the original filter, it need as 1/4 inch coupler? or asking differently,- Panasonic works with 1/4 inch hoses?

roli, · Reply

Hello,

the hose from outside has 1/4 inch diameter, that's 6,35 mm. Right. :)

But inside, where the original bottle-filter is connected, the inlet hose has 5/16 inch (ca 8 mm) and the outlet hose has 1/4 inch.

In STEP 6 picture 2 is shown the different diameters. The second grey coupler is thicker, thats an adapter from 1/4 inch to 5/16 inch. I've made a new picture for you in STEP 7.

Friendly greets. :)

Schwarzstein,
