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. It needs to
be installed upright to maximize contact with
media. It is recommended your system be
installed inside and out of direct sunlight. If this
is not possible and the system is outdoors or
in a sunny area, the installation requires the
use of sun-proof 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 the unit by flushing:
It is very important that this system is flushed
properly prior to final installation. 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 cloudy water
to flow from the outlet into a bucket
or drain. Flush the NAC tanks for
5-10 minutes. Once the unit
has been properly flushed,
be sure the white washers
are properly set inside
the inlet and outlet ports.
Disconnect it from the garden
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
plumber’s tape. Leave two-three threads
exposed and do not exceed seven layers of
plumber’s 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.
