o

  Connect the 3/8 OD tubing (supplied) to the quick connect fitting on the outlet of 

the Filtration box. 

o

  Connect the other end of the 3/8 OD tubing to the 

Natura

 Water Refrigeration 

unit. To do this, reach inside the top of the unit (the unit is already opened) and 

find the coil of tube that has a quick connect fitting with a plug on the end. Feed 

the end of this tubing through the 2” diameter hole in the bottom of the unit. 

Remove the plug and set aside. Now connect this tube to the one from the 

filtration box. 

o

  Make sure that the tube does not tangle and does not come in contact with any 

heat sources. 

o

  Install the filter sumps in the filtration box. 

NOTE:

 

MAKE SURE THAT THE 

PROTECTIVE PLASTIC WRAPPERS ARE REMOVED FROM THE FILTER 

CARTRIDGES

! The sediment filter (white) is located on the left. The carbon 

filter (black with netting) is located on the right. Make sure that the cartridge 

slips down over the stand pipe in the bottom of the sump. Hand tighten – DO 

NOT OVER TIGHTEN. 

o

  When laying out the supplied tubing for installation, if it is necessary to pass the 

supply tubing under the platform, it is important to have good tubing protection 

to prevent the tube from getting cut. Copper pipes or tubing of the same 

diameter before and after the filtration box and to the unit can be used instead 

of the plastic tubing supplied. 

o

   Always use certified plumbing materials for contact with potable water.
