spills during removal of the filter housing.
Figure 1
2. Open faucet to release pressure.
3. Unscrew fittings from both ends of existing post filter.

INTENDED USE
• This product is intended for use as a post filter for an RO
system with a tank.
• This product is intended for use on drinking water.
• This product is intended to remove both heterotrophic
bacteria and chlorine thereby ensuring complete taste
and odor removal from water coming from the RO system
storage tank.*
• This product is intended to ensure the aesthetics of
product water dispensed from an RO system storage tank.
• This product is not intended for use on systems where
the influent source to the RO system is known to be
microbiologically contaminated OR where the product
water is known to contain pathogenic microorganisms.
• This product is not intended to protect
immunocompromised users from skin contact or
ingestion-related illness.
• Membrane filtration provides 99.9999% reduction of
bacteria by mechanical means.*
• NSF/ANSI Standard 53 certified to reduce cysts such as
Cryptosporidium and Giardia by mechanical means.
* Tested & verified by independent laboratory testing.
PRECAUTIONS
WARNING:
Do not use with water that is microbiologically
unsafe or of unknown quality without adequate
disinfection before or after the system.
Systems certified for cust reduction may be
used on disinfected waters that may contain
filterable cysts.
CAUTION:
Filter must be protected against freezing, which
can cause cracking of the filter and water leakage.
NOTE: Substances reduced are not necessarily in your water.
Filter must be maintained according to manufacturer’s
instructions, including replacement of filter
cartridges.
NOTE: Keep this unit clean with soap and water. Do not use
spray cleaners or insecticides near the unit.
NOTE: Do not install close to a heat source.
NOTE: Comply with all state and local laws and regulations.

PERFORMANCE DATA
Important Notice: Read this performance data and compare
the capabilities of this system with your actual water treatment
needs. It is recommended that, before installing a water
treatment system, you have your water supply tested to
determine your actual water treatment needs.
This system has been tested according to NSF/ANSI 42 and 53
for reduction of the substances listed below. The concentration
of the indicated substances in water entering the system
was reduced to a concentration less than or equal to the
permissible limit for water leaving the system, as specified in
NSF/ANSI 42 and 53.
Test Conditions
Flow Rate = as noted for filter system
Inlet Pressure = 60 psi (4.1 bar)
pH = 7.5±1
Temperature = 68°F ± 5°F (20°C ± 2.5°C)
Operating Requirements
Pressure = 20-125 psi (1.4–8.62 bar)
Temperature = 40-100°F (4.4–37.8°C)

5. Remove tubes from fittings by pressing in the collar around
the fitting while pulling the tubing out with your other hand.
Figure 3
6. Tape fitting threads with three wraps of plumber tape and
attach fittings to the new post filter.
CAUTION:
Ensure the tape is not touching the O-ring on the
fitting or a leak may occur.
NOTE: The post filter has an arrow on it showing the
direction of flow. The tee fitting connects to the inlet
side of the filter and the elbow fitting attaches to the
outlet side.
NOTE: Hand tighten fittings, then tighten with wrench 1/4
turn.
7. Attach the post filter to bracket with the tee fitting on the
right hand side.
NOTE: The diameter of the GS-210RO-MF post filter is 2.5",
and may be different than the existing post filter. Two
2.5" x 2.5" clips (P/N 357780) are required to properly
install the post filter to the RO element housing.
Contact your local water treatment professional for
details.
8. Attach tubes to fittings by pushing in until the tube stops.
Check to see if tube is in place by trying to gently pull tube
out.
9. Open the valve on the storage tank and turn on the cold
water supply.
10. Open the faucet and allow water to run through the faucet
for 12 hours to fully rinse out the hollow fiber membrane.
Close faucet when rinse is complete.
NOTE: The post-polishing filter may contain fine black
carbon particles. These fines are harmless, but may
make the water appear gray in color. The carbon fines
are flushed from the system with one full tank volume
of water.
NOTE: Initially the water may appear cloudy. This is a result
of air trapped in the post-polishing filter. It is not
harmful and will disappear in a matter of minutes. It
may take up to a week after installing a new post-
polishing filter for the trapped air to dissipate.
The system is now ready for operation. You can now enjoy
quality water from your Reverse Osmosis System.
REPLACEMENT CARTRIDGES
Contact your local water treatment professional for
replacement cartridges.
Membrane filtration provides 99.9999% reduction of bacteria by
mechanical means.

Cryptosporidium and Giardia by mechanical means.
INSTALLATION INSTRUCTIONS continued
The GS-210RO-MF has been Tested and Certified by NSF
International against NSF/ANSI Standard 42 and 53 for the
claims specified in the Performance Data Sheet.
The GS-210RO-MF Inline product has been tested by BioVir Laboratories Inc. and found
to meet all the requirements of protocol PWP-LAB-401, developed for verifiying the
integrity of products that claim 99.9999% or greater removal of bacteria. The protocol
challenges the product at the beginning, end, and up to two times throughout the life of
the product for bacteria at an influent concentration of 8-log. Products that are tested
under this protocol are run at open flow, 60 psi, 50% cycle, for no less than 8 hours per
day.
Membrane filtration provides 99.9999% reduction of bacteria by mechanical means.
GS-210RO-MF demonstrated a greater than 7-log reduction
