This high capacity whole house filter package is designed specifically to remove sediments down
to a level of 10 microns thereby improving water clarity, taste, and odor, and protecting your
home’s plumbing system (including other water treatment equipment) from damage and pre-
mature clogging due to sediment build-up. This package features Hydronix's unique SDC Series
multi-gradient sediment filter. This filter uses the entire depth of its media by trapping the largest
sediment particles on the outside of the filter, then gradually stepping down the size of particles it
will reject as the water moves closer to the core of the filter. The outer layer is rated at 75
microns. The subsequent layers are rated at 50 microns, 25 microns, and finally 10 microns. The
result is longer filter life, greater dirt-holding capacity, higher flow rates, and remarkably low
pressure drop. The 100% pure polypropylene media is highly resistant to bacteria, making this an
excellent choice for both well water and municipal water treatment applications.

Note: We recommend that this product be installed by a professional plumber. If you
install this product yourself, please ensure that your installation meets all local building
and plumbing codes. The following instructions are meant only as a general guide and
should not be considered a substitution for your local plumbing and / or building codes.
You will need the following plumbing supplies:
two (2) shut-off valves with suitable sized unions to connect to your incoming and outgoing
water lines. You can select threaded, compression or sweat (soldered) fittings on the shut-
off valves as desired.
plumber’s cement or Teflon tape for all threaded fittings.
The plumbing connections on the inlet and outlet of the water filter housing are 1” inside diameter
(female) NPT threaded fittings. You may require additional plumbing adapters to connect to your
selected shut-off valve. Your plumber will have all of these items, or they can be purchased at
your local hardware or plumbing supply store at minimal cost (take these instructions to the store
with you so the store clerk can make sure you get everything you need). Note: In older homes
with galvanized piping all fittings should be threaded.
Select an installation location. There are a variety of ways to install your filter system
into a main or branch water line. As a general recommendation, this filter should be installed on
cold water line
after the pressure tank or water meter. Select an installation location
with convenient access for regular filter replacements and maintenance.
Shut off the main water supply and drain the pipes. Opening the highest and lowest
fixtures in the house will help drain the pipes.
. Using a pipe cutter, cut out a section of your main water line at the point where you
want to install your filter system. There will probably be some water remaining in the system, so
be sure to have a bucket and some rags handy to clean up any small spills. Make sure that the
section of water line you remove is appropriately sized such that all of the components of the
system including the shut-off-valves, adapters, and the black filter cap will fit snuggly when
assembled. If in doubt, cut a smaller section at first – you can always remove a slightly larger
section upon final assembly if necessary.
Assemble the components according to Diagram 1 below. We recommend installing
shut-off valves both upstream and downstream of the filter housing. A shut-off valve is not
required on the upstream side of the housing if the filter will be located within a couple of feet of
the main line shut-off valve. Plumber’s cement or Teflon tape should be used on all threaded
fittings. Use the mounting bracket and screws provided so secure the black filter housing cap to
the wall or other solid surface. Allow enough space below the black cap to accommodate the blue
housing sump plus a minimum of an additional 3 inches of clearance.
Use extreme caution when soldering any connections between the main water line and
the shut-off valve or between the shut-off valves and filter housing if your filter housing
is connected to the pipes, or serious damage to the filter housing could occur. If at all
possible, solder all connections before the pipe is connected to the filter housing.
If your water pipes are metal (galvanized or copper), they may be used to ground
electrical systems, appliances, or your phone line. If this is the case, be sure to install
regulation ground clamps to the metal pipe on each side of the plastic filter housing and
connect a jumper wire between the 2 clamps (#4 gauge solid copper wire
recommended). Alternatively, your plumbing code MAY allow you to connect the
jumper wire to the 2 shut-off valves (see diagram). Consult a certified electrician or
plumber if you are unsure.
Remove the protective plastic wrap from the filter cartridge and place it in the blue
housing sump. At the bottom of the sump, there is a raised portion in the middle (standpipe) that
will help center the filter in the housing. The standpipe will fit inside the hole that runs through
the middle of the filter cartridge. Store any spare filters in a cool dry place for future use. Check
to make sure that the O-ring is seated properly in the grove at the top of the blue housing sump,
then screw the blue housing sump containing the filter cartridge onto the black housing cap. Use
the spanner wrench to tighten.
Turn on the water and inspect all plumbing connections very carefully for leaks. Also
inspect the seal between the black housing cap and the blue housing sump to ensure that the O-
ring has formed a good seal. Tighten this connection again using the spanner wrench if
necessary. If this connection still leaks, turn off the water supply and check to make sure that the
filter is aligned properly in the housing and repeat your test for leaks. When you are confident
that all connections are sound, run cold water for 2 minutes at any faucet to purge air out of your
system and to prime the filter.
1. The manufacturer recommends that the blue housing sump should be replaced every 10 years or if you
notice any cracks or damage.
2. This filter system should not be used with water that is microbiologically unsafe or of unknown quality
without adequate disinfection before and/or after the system.
3. Water filter systems should never be exposed to freezing temperatures - severe damage to the filter and
housings could result. Such damage is not covered under any warranty.
4. After prolonged periods of non-use (such as a vacation), it is recommended that the system be flushed
thoroughly for at least 5-10 minutes before using the water.
5. The contaminants or other substances removed or reduced by this water treatment device are not
necessarily in your water.
6. If you suspect that your water pressure will at any time exceed the maximum rating of 90 PSI (6.2 bar), a
pressure regulator must be installed before the system. It is recommended that the pressure regulator be
set at 75 PSI (5.2 bar) or less.
Maintenance and Filter Replacement Information:
To maintain the optimal performance of your whole house water filter system, filters should
always be replaced in accordance with manufacturer specifications. Filters may need to be
replaced more frequently then specified, depending on the level of contaminants, particularly
sediments, in your water supply. If significant water pressure reduction is noticed, the filter may
have become clogged. We recommend that you keep a “Filter Replacement Log” attached to your
system where you can record the date of filter changes and that you write a note on your
household calendar reminding you of filter replacement schedules.

Filter Cartridge Replacement Procedure:
Turn off the water supply to the system using the shut-off valves you installed on the inlet
and outlet of the filter housing. Depress the red pressure release button on the top of the
filter housing cap to allow any pressure inside the housing to escape, thereby allowing the
blue filter sump to be removed easier.
Unscrew the blue sump (bottom of the housing) from the cap using your spanner wrench
(included with original purchase of your system).
Locate and remove the large O-ring. Try not to remove any of the lubricant. The housing
O-ring should be replaced at least once annually or at each filter change if any damage to
the O-ring is noted (kinked, cracked, stretched, etc.), or if any leakage between the black
housing cap and the blue housing sump is detected and does not seal after tightened with
the spanner wrench. Put the O-ring in a safe place where it will not get dirty or otherwise
Replacement O-Ring: Pentek Buna-N Big Blue O-Ring #151122
Take out the old filter cartridge and discard it.
Scrub the bottom of the housing and cap with dish soap and warm water using a sponge or
soft cloth. Fill 1/3 with water and add about 2 tablespoons of household bleach. Scrub to
disinfect (we recommend that you use rubber gloves).
Rinse all parts thoroughly!
Lubricate the O-ring with food-grade silicon lubricant if needed. Insert O-ring in the
groove at the top of the blue sump and press into place.
Make sure the O-ring is
seated level in the groove!
Remove the protective plastic wrapping from the new filter cartridge and insert the
cartridge into the housing sump, making sure that it slips over the standpipe in the bottom
of the housing.
Screw the blue sump onto the black housing cap tighten using the spanner wrench
not over tighten.
Turn on the water supply slowly to allow the system to fill with water. Depress the red
pressure release button on top of the unit again to release any trapped air.
carefully for leaks.
If a leak is found, first inspect the O-ring to ensure that it is seated
properly before tightening the sump more. Tighten using the spanner wrench as necessary
to achieve a good seal and stop leaks.
Flush the system by running water from a nearby faucet for 2 minutes. Wait one hour,
and flush again for another 2 minutes prior to using the water.
