Carbon Filter Replacement Procedure
1. De-pressurize the system.
2. Locate the carbon prefilters (Fig. 3, Item 4). To remove the carbon prefilters, unscrew the filter bowls to the left
(counterclockwise as viewed from the bottom), using a filter bowl wrench or by hand. Remove the filters from the
bowls and discard them.
3. Inspect the O-ring seals for damage. The O-rings should be replaced if they are damaged or distorted. Clean the
filter bowls with warm water and soap.
4. Insert the new carbon prefilters into the filter bowls. Screw the filter bowls onto the filter heads by hand or use the
filter wrench. Be careful not to over-tighten if you are using the filter wrench.
Post Treatment Filter Replacement Procedure
1. De-pressurize the system.
2. Close the ball valve on the storage tank.
3. Locate the posttreatment filter (Fig. 3, Item 7). Loosen the black plasic nut on the inlet fitting to relieve pressure.
Use a small container to catch any spillage. Carefully open the housing. Remove the filter from the bowls and
discard it.
4. Inspect the O-ring seals for damage. The O-rings should be replaced if they are damaged or distorted. Insert the
new posttreatment filter into me filter bowl. Screw the filter bowl onto the filter head by hand or use the filter
wrench. Be careful not to over-tighten if you are using the filter wrench.

Purge air from the prefilters by allowing water to flow out of the drain valve until you see a steady, air free stream
of water. Close the drain valve.
