C. INTERNAL PREFILTER REPLACEMENT (CARBON OR
STAINLESS STEEL)
The carbon prefilter may require replacement more frequently
than once a year during the annual maintenance or if there
is a chlorine taste in the water after the system has been in
use for a period of time. The carbon prefilter may also remove
some other tastes and/or odors. In some cases, the carbon
prefilter may become fouled earlier than one year depending
on the intake water source.
The stainless steel prefilter generally does not need to be
replaced. It may become dirty and may be cleaned under a
tap. Replace the stainless steel prefilter if damaged.
Replacement Instructions:
1. Close the inlet valve.
2. Depressurize the system by performing a manual flush
sequence. Refer to the instructions in the Controller
Functions section for how to perform a Manual Flush
sequence.
For horizontally-mounted systems, connect a 1/4" tubing
to the inlet mini ball valve, direct the other end of the 1/4"
tubing to a drain or a pail, and open the inlet mini ball
valve to drain the water in the internal prefilter cavity.
3. Using the cap wrench, remove the system cap.
4. Put on a pair of disposable gloves and carefully remove
and dispose of the internal prefilter.
Check that the thimble filter is in place, seated in the
spigot. Inspect and clean thimble filter as needed.
5. Remove the new internal prefilter from the packaging.
6. Insert the new internal prefilter into the prefilter cavity
and push it down gently to ensure it is seated properly.
7. Replace the system cap tightly.
8. Open the inlet valve slowly.
9. Dispose of the disposable gloves.
D. EXTERNAL PREFILTER REPLACEMENT
Depending on the water quality, the external prefilter
may need to be washed or replaced prior to the annual
maintenance. A decrease in water pressure at the taps may
indicate that the external prefilter may need to be replaced.
NOTE: For rinsing of the used external prefilter cartridge, save
a bucket of filtered water from a tap in the dwelling before
servicing the external prefilter. Water supply in the dwelling will
be interrupted temporarily during servicing.
Replacement Instructions:
1. Close the inlet valve to the external prefilter.
2. Attach a 1/4" tubing to the mini ball valve at the bottom
of the external prefilter. Direct the other end of the 1/4"
tubing to either a drain or a pail.
3. Open the mini ball valve slowly.
4. Press and hold down the red button on the external prefilter
head to shorten the time to drain the external prefilter.
5. Once the external prefilter is drained, close the mini ball
valve.

6. Using the housing wrench, loosen the external prefilter
housing from the external prefilter head.
7. Wear a pair of disposable gloves and carefully remove
the external prefilter cartridge from the external prefilter
housing.
8. Rinse off the used external prefilter cartridge. If the used
external prefilter cartridge is no longer reusable, replace
it with a new one. If a new external prefilter cartridge is
to be installed, remove the plastic wrap on the outside
of the cartridge.
9. Ensure that the O-ring is in good condition and seated
at the lip of the external prefilter housing. If necessary,
replace the O-ring with a new one.
10. Screw the external prefilter housing into the external
prefilter head and tighten the connection using the
housing wrench.
11. Open the inlet valve slowly and depress the red button
on the external prefilter head to allow air to escape from
the external prefilter housing.
12. Once water emerges from the button, release the button.
13. Dispose of the disposable gloves.
