How the Automatic Sediment Filter Works
The EcoWater Automatic Sediment Filter is designed
to be plumbed into a home’s incoming water supply
pipe, where it will capture particles of sediment from
the water and periodically flush them down the drain.
The unit has an electronic control that counts down the
days until the next automatic flush of collected sediment particles. The number of days is programmable.
The electronic controller runs on a 9 volt battery. The
controller will indicate when the battery needs to be
replaced. An optional AC power adaptor (P/N
7302835) may also be purchased to eliminate the
need for batteries.
NOTE: This product is designed to reduce sand,
grit, debris, pipe scale and other loose particulate
matter. On water supplies that contain sticky sediment including mud, silt and clay, you may have to
remove the sump and clean the screen periodically.
Three sizes of filter mesh are available. A 60 micron filter is included with the ASF unit, and optional 100 or
150 micron filters can also be purchased (see spare
parts list at the end of this manual).

Planning the Installation
ALWAYS INSTALL THE FILTER UPRIGHT
To operate properly, the Automatic Sediment Filter
must be installed with the sump pointed straight down.
When possible, install the filter on a horizontal section
of the household’s main incoming water pipe. If the
available incoming main house water pipe runs vertically where you want to install the filter, buy 90° pipe
elbows and plumb a detour, as shown in Figure 4.
Allow enough space under the filter (6” minimum) to
remove the sump (to clean or replace the filter screen).
Allow enough space above the filter to remove the top
cover (to change batteries, etc.), as shown in Figure 4.

REVERSING THE FACEPLATE / DISPLAY
The Automatic Sediment Filter must be installed with
the water flowing into the side of the filter marked IN.
Remove the unit’s top cover and observe the IN and
OUT markings. Depending on the direction of water
flow and the viewing angle, the faceplate may need to
be reversed (turned around to face the opposite direction) so that it does not end up against a wall or other
obstruction. This can be done either before or after
the filter is installed on the plumbing:

upward.
2. With a phillips screwdriver, remove the 2 screws
holding the faceplate assembly to the filter head
(See Figure 5).
3. Lift the faceplate assembly up and turn it around
180°, taking care not to pull on the wires between
the electronic control board and the valve solenoid.
4. Lower the faceplate assembly into place on the
opposite side of the head and reinstall the 2 screws.
5. Slide the top cover back onto the ASF and push it
down to snap into place.
FIG. 5
MOUNTING BRACKET
3"
A metal bracket is included with the Automatic
Sediment Filter to support the assembled filter and
plumbing when necessary. It may be mounted to a
wall or wall framing member with 2 screws (included),
as shown in Figure 6.
Mounting
Bracket
The 2 mounting bracket screws should be installed
before the filter is installed on the plumbing. When
installing the plumbing, be sure to put the bracket in
position around the ASF before installing inlet and outlet fittings. The bracket can not be put on after the
inlet and outlet fittings are installed.

Installation Requirements
PLUMBING CODES
VALVE DRAIN REQUIREMENTS
All plumbing must be completed in accordance with
national, state and local plumbing codes.
Using the flexible drain hose (included), measure and
cut to the length needed.
Avoid drain hose runs longer than 10 feet. Make
the valve drain line as short and direct as possible.
In the state of Massachusetts: The Commonwealth
of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used
for this installation.
If possible, avoid elevating the drain hose. This
could reduce the effectiveness of the flush cycle,
especially in a low pressure application.
The drain must be capable of handling a flow of 5 to
10 gallons per minute, depending on the home’s
water pressure.
AIR GAP REQUIREMENTS
The drain must be capable of handling the sediment
being flushed from the filter.
A drain is needed for sediment flush discharge water.
A floor drain, close to the Automatic Sediment Filter, is
preferred. A laundry tub, standpipe, etc. are other
drain options. The valve drain hose must be secured
in place, since drain water will be spraying from the
end of the hose at a high rate during flush cycles.
Leave an air gap of 1-1/2” between the end of the
hose and the drain. This gap is needed to prevent
backflow of sewer water into the Automatic Sediment
Filter. Do not put the end of the drain hose into the
drain.
GROUNDING INFORMATION
(for Installations on Metal Pipe)
The house main incoming water pipe is often
used to ground electrical outlets in the home.
Grounding protects you from electrical shock.
Installing the Automatic Sediment Filter may break
this ground. To restore it, buy and install a #4
copper wire across the filter, tightly clamped at
both ends, as shown below.

Routine Maintenance
CLEANING THE FILTER SCREEN
It may be necessary to manually clean the filter screen from
time to time. On water supplies that contain sticky sediment
including mud, silt and clay, you may have to remove the
sump and clean the screen frequently. Also, if the ASF has
not been automatically flushing for any reason, such as a
dead battery, a larger amount of sediment than normal may
have accumulated in the sump. In this case it is recommended that the sump and filter be cleaned manually (an
excess amount of sediment could plug the valve).
1. Before shutting off the water supply (as directed in Step
2), run a bucketful or sinkful of water to use for cleaning
the filter screen.
Sump
2. Shut off the main house water supply valve upstream from
the Automatic Sediment Filter.
3. Open a cold water faucet in the house (downstream from
the ASF) to depressurize the system. Then close this
faucet again
4. Remove the sump by turning it to the left to unscrew it
from the ASF head (See Figure 24). Be prepared for
water to drip out of the ASF head when the sump is
removed.
Turn to the
left to remove
(with water shut off)
FIG. 24
5. Remove the filter screen assembly by pulling it down out
of the ASF head (See Figure 25).
6. Using the water you saved in Step 1, wash the filter
screen assembly. If necessary, gently scrub the filter
mesh with a soft brush to remove material from the pores.
7. The drain straw may have come out of the ASF head
when the sump and filter screen were removed. If so,
reinsert it into the small hole at the center of the head
assembly (See Figure 25).
8. Make sure the o-ring is in place on the filter screen
assembly (See Figure 25). Make sure that no sediment
particles are on the o-ring or the corresponding sealing
area in the head. Slide the filter screen over the drain
straw and into the corresponding hole at the center of the
ASF head. Push it in to engage the o-ring seal.
9. Make sure the large o-ring is in place on the sump (See
Figure 25). Make sure no sediment particles are on the oring, sump threads or corresponding threads in the ASF
head. Slide the sump over the filter screen and screw it
into the ASF head to seal. Do not overtighten.
10. Open a cold water faucet in the house downstream from
the ASF.

11. Turn the main house water supply back on.
12. Close the faucet that you opened in Step 10 after air has
been expelled from the system and water is flowing
smoothly with no spurting.
13. Check that there is no water leaking from the sump
threads. Tighten sump if necessary.

flush cycle
1. Valve is plugged.
Manually clean filter screen (See Page 14). After water has been turned
back on, initiate another clean cycle (hold CLEAN button for 2 sec.).
Repeat if necessary. If caused by too great a volume of sediment, may
be necessary to reduce number of days between automatic sediment
flushes (See Page 13). If this does not clear plugged valve, it may be
necessary to disassemble valve and clean manually (See “Disassembly
of Valve,” below).
2. Drain hose is plugged.
Disconnect drain hose, remove obstruction and reconnect.
3. Insufficient water pressure.
Make sure water pressure requirement (30 psi minimum) is met. Shorten
drain line.
4. Misapplication of product.
See application information (“How the Automatic Sediment Filter Works”)
on Page 5.
1. Solenoid seat is dirty.
Initiate several clean cycles. If leak continues, then remove valve solenoid and clean seat area (See “Disassembly of Solenoid”, below).
2. Valve is plugged or valve
seat is dirty.
Manually clean filter screen (See Page 14). After water has been turned
back on, initiate another clean cycle (hold CLEAN button for 2 sec.).
Repeat if necessary. If caused by too great a volume of sediment, may
be necessary to reduce number of days between automatic sediment
flushes (See Page 13). If this does not clear plugged valve, it may be
necessary to disassemble valve and clean manually (See “Disassembly
of Valve,” below).
