How to change the filters?
Carefully follow the instructions that come with the filter package.
O-rings: Replace every 3 years or sooner if a leak happens at the O-ring.
The package comes with spare O-rings for the pre-filter housing and the membrane housing. Please
save them with this manual.
Tank Maintenance
Emptying and refilling the tank at least once a month is recommended. This keeps the water inside
the tank fresh and not sitting for an extended period.
What should I do with the system when going out of town?
When leaving for an extended time, you will want to shut off the water supply to the system and
empty the tank. To do this, close the knob on the feed water adapter, and open the faucet until it stops
running. This will signify that the tank is empty. The filters should be replaced if the system is not
used for over a week, as they will be sitting in stagnant water. If you expect to be gone for more than
a week, you will want to remove the RO membrane and store it in a damp Ziploc bag in the
refrigerator.

Optional Add-on
Ice Maker Connection Kit (Model# ICEK)
The iSpring ICEK can be purchased separately to feed RO water to your refrigerator for crystal-clear
ice cubes and great-tasting water. It can be easily installed to connect the RO system to your fridge's
ice maker or water dispenser.
TDS Test Meter (Model# TDS2 or TDS3)
The TDS test meter can be used to check your tap water quality regularly and help determine the time
for filter replacement.
Tubing (Model# T14B or T14W)
1/4'' food-grade tubing in a 50' roll, which is good to use for tubing replacement and extension as
needed.
Top Mount Faucet Installation Kit (Model# AIG1)
A US patent pending tool-free product for Countertop RO faucet installation. It works great for
countertops with 1'' - 1 ½'' (D) holes and also fits a standard 7/16'' drinking faucet stem. It is highly
recommended that you watch the video "How to install a drinking water faucet WITHOUT
reaching under sink | iSpring AIG1 Installation Kit" on YouTube.
iSpring Tanks
This RO system can be used with a 20 – 200 gallons storage tank. A tank helps meet the impulsive
high-volume demand and build a commercial or whole-house Reverse Osmosis solution.
