Helpful Tips: To avoid contamination, we
recommend the use of sterile gloves while
changing the system components.
When changing the membrane cartridge,
verify that the rubber brine seal and O-rings
are secure and in place. Always lubricate the o-
rings with a NON-PETROLEUM based lubricant
to ensure the longevity of the o-rings. Never
over-tighten the housing to the cap _ HAND
TIGHT ONLY!
!
Important Note:
It is important to maintain
the quality of your system by using only
genuine RainSoft replacement filters and
cartridges. Other “made-to-fit” alternative
filters and cartridges claim to perform the
same duties as the original RainSoft parts, but
these items are not approved for use in your
system! “Made-to-fit” alternative filters and
cartridges will increase the probability of
leaks, putting your entire system at risk! Also,
many aftermarket replacement filters are not
tested for safe contact with drinking water.
When “made-to-fit” alternative filters and
cartridges are placed into your RainSoft
Ultrefiner II Premium Drinking Water System,
the product warranty will become null and
void and the system will lose its NSF certifica-
tion. To guarantee proper operation and certi-
fication of your RainSoft Ultrefiner II Premium
Drinking Water System, please use genuine
RainSoft parts.
How to Change the Filters
1. Turn off the cold water supply to the Ultrefiner II system.
2. Close the storage tank shut-off valve and then open the Ultrefiner II
faucet.
3. Place a drip pan or bucket if necessary to catch the water from the
filter canisters to prevent spillage.
4. To replace the filters, use a Slim Line Spanner Wrench (not supplied)
to unscrew the filter housings from the cap (see figures 14).
5. Replace the filters and reassemble (see helpful hints).
6. Once assembled, turn the drain barrel to F position. (see figure 12 on
page 11).
7. Turn on the inlet water to the Ultrefiner II system.
8. Open the storage tank valve and Ultrefiner II faucet. Allow the water
system to flush for 15 minutes.
9. Turn the Drain Barrel back to predetermined number setting and turn
off the faucet and allow a minimum of 2 hours for the tank to fill up.
If you have replaced the membrane, please open the faucet after 2
hours to drain the first tank of water. This will properly flush the
membrane.

Important Note: When Unscrewing Filter
Housings use of Slim Line Spanner Wrench is
required. Unscrewing filter housings with use
of other unapproved tools can damage the
filter housings and void warranty.
!
Important Note: It is recommended that the
sump o-rings be replaced on each filter change
to insure proper compression of the o-ring,
failure to do so may result in over tightening of
the sump to create a seal and can cause undue
stress on the sump and cap that can lead to
cracking of these components under pressure.
