Installation Notes
• Read all precautions, installation and operating
instructions carefully and completely before
installing the unit.
• Ensure all contents are present prior to
installing.
• Lay out system in appropriate configuration.
Improper sequence of equipment will affect
performance, and could possibly damage your
system.
• For systems with pro-grade installation kits,
anticipate the addition of pex tubing, clamps
and mounting screws to install unit properly
(available at your local home improvement
store or through your plumbing contractor).
Due to the varieties of home design, not all
configurations can be addressed in this guide.
Components and time of installation will vary.
Please refer your plumbing professional to our
Installation Guide.
• Do not install this filter where the line pressure
may exceed 100 psi. Operating pressure range:
20psi – 100psi.
• Select an appropriate installation location.
Dimensions of systems vary—always allow an
estimated minimum of 50” clearance for height
of tank, and a minimum of 30” for floor space.
Your plumber will be installing the system in
an area where the main water line enters your
home, prior to your water heater.
• Do not install the unit on its side or in direct
sunlight. Outdoor installation requires the use
of sunproof sumps. Please contact our sales
and service department 866-238-5855 to
discuss the specifics of your installation.
• Full warranty contingent on installation by a
licensed plumber.
• Install on cold water lines only (40° – 90°F).
Protect unit from freezing.
• Installation of the filter must comply with
existing state and local plumbing codes.
Austin Springs is not liable for consequential
or incidental damages due to improper
installation.
Do not use with water that is microbiologically unsafe or of
unknown water quality without adequate disinfection before or
after the system. Systems certified for cyst reduction may be used
on disinfected water that may contain filterable cysts.
Installation
1. KEEP UPRIGHT AT ALL TIMES.
2. Remove the red shipping caps from the inlet &
outlet ports on the main housing.
3. Precondition by “surge flushing”:
It is
important that this system is flushed prior
to installation. The granular medium used in
the bottom tank contains 1-2% by volume of
carbon fines that should be flushed out prior
to use. The best method for purging these
carbon fines is “surge flushing”:
Using the supplied adapter,
connect a garden hose to the
inlet port so that the water
will flow into the system and
out of the outlet port. Slowly
turn on the water and allow
the discolored water to flow
into a bucket or drain. The
first few gallons will appear black
and cloudy. After an initial
2-5 minute flushing, begin a
period of “surge flushing.”
Turn the water on for 30
seconds and then off for 30
seconds repeatedly for 5-10
minutes or until initial surge
of water is completely clear and
free from discoloration and cloudiness. Once
the unit has been flushed, be sure the white
washers are properly set inside the inlet and
outlet ports. Disconnect it from the hose and
position it for final installation.
4. Turn off main source water supply prior to
installation.
5. Install the unit to the main water supply
using the supplied components. Do not over
tighten fittings, as this may cause leakage
and broken fittings. Do NOT use pipe dope.
The use of pipe dope voids the warranty.
You may use NSF Certified pipe primer, glue
and teflon tape. Leave two-three threads
exposed and do not exceed seven layers
of teflon tape. More than seven layers will
cause the nipple to crack and leak.
6. IMPORTANT:
The inlet piping assembly
(valve, pre-filter, main filter
unit, union and nipples)
must be firmly braced and
supported.
7. Once installation is complete, slowly
turn the water on and inspect for
leaks.
8. Once the unit is installed
and checked for leaks, open
the water faucet closest to the
installed unit and allow water
to run for 10 minutes for the final
flushing period.
9. This unit must be installed by a licensed
plumber to validate the warranty.
