Replacing the Ultra Filter
Cartridge
NOTE:
Always install new Carbon Ele-
ment after replacing the Ultra
Filter Cartridge.
1. Turn off water to the system by clos-
ing the Inlet Ball Valve and Outlet
Ball Valve.
2. Press the FLUSH button to flush the
system and relieve pressure. Repeat
several times to ensure permeate
tank is empty.
3. Remove the Carbon Element if pres-
ent.
4. Locate the long hooked tubing on
the right and disconnect the long
end from the tee by pushing the
collet squarely against the face of
the fitting.
5. With the collet pushed in place, pull
the tubing from the fitting with your
right hand.
NOTE:
Water may drain from the tubing
as it is removed. Make sure there
is enough room next to the sys-
tem to remove the cartridge.
6. Remove the Snap Ring (Figure 8)
from the Ultra Filter Housing. Grab
the raised lug with a pair of pliers
and pull towards the center of the
End Cap and away. The Snap Ring
should lift out of its groove.
7. Remove the End Cap, End Cap O-
Ring, and Cartridge (Figure 8) from
the housing.
NOTE:
If the Cartridge does not easily
come out of the Housing, remove
the opposite End Cap for assis-
tance during Step 5.
8. Inspect the Large End Cap O-rings
and End Cap O-ring for nicks or cuts.
Replace as needed.
9. Lubricate all O-rings with a food-
grade silicone lubricant. Apply a light
coating of lubricant to the inside
center tube at both ends of the new
cartridge.
10. Record the serial number of the new
cartridge. The cartridge serial num-
ber is engraved on one end of the
outer tube (for example: 05K 12013).
11. Install the End Cap O-ring on the End
Cap and insert the Large End Cap
into the end of the new cartridge.
12. Position the new cartridge and End
Cap at the housing and gently insert
into the housing.
13. Press the End Cap into position until
it is fully seated and the Snap Ring
groove is visible.
14. Install the Snap Ring by guiding the
non-lugged end into the groove
first, pushing outward and working
around the ring until it snaps into
place.
NOTE:
Make sure that the Snap Ring is
fully seated before turning the
water on.
15. Reattach the tubing that was re-
moved in Steps 3 and 4. Be sure the
tubing is pushed past the O-ring.
NOTE:
Make sure the fitting is complete-
ly inserted onto the tubing past
the O-ring. A loose connection
results in leaking at the point of
connection.
16. Rinse the new Ultra Filter Cartridge
before placing the system back into
operation. Follow the Rinsing the
Ultra Filter Cartridge, Sanitizing the
System and Lines, and Rinsing the
Carbon Element procedures in the
Installation section of this manual to
complete the cartridge change.
17. When rinsing is complete, repressur-
ize the system by opening the Outlet
Ball Valve then opening the Inlet Ball
Valve.
