disconnected. Open the Feed Water Adapter Valve (AFW43) and Cold Water Supply Valve
(CWSV), and flush the first three stages into a bucket until the water turns clear.
8.3 Once the water is clear, shut off the AFW43 and reconnect the tubing to the RO membrane
housing cap. You will want to flush the first three stages like this whenever they are
changed.
8.4 Open the RO faucet. Slowly open the AFW43 back up and check for any leaks. The top 3
causes of leaks are 1) The tubing is not fully inserted into the quick-connect fitting. 2)
The O-ring is not in the correct place or is kinked. 3) The Housing/Cap is not
tightened properly or is misaligned with the threads.
8.5 Within 5 minutes, the booster pump will kick on and RO water will start slowly trickling
from the faucet. Let the faucet trickle for at least 15 minutes to flush out the entire system
apart from the tank. The water may appear black at first due to loose carbon from new
carbon filters. It will eventually turn clear apart from many tiny air bubbles leaving the
system.
8.6 Shut off the RO Drinking Faucet. Open the Tank Shut-off Valve. Wait for the tank to fill up
completely. It will take 1 to 2 hours depending on your water temperature (40F-100F, the
warmer the faster) and source water TDS (up to 750 ppm, the lower the faster). The pump
will shut off automatically when the tank is full.
8.7 After the tank is full, open the RO Drinking Faucet to drain the tank completely. Do not use
the first tank of water. Let it drain into the sink until the stream turns back to a trickle. This
means the tank has emptied and you can close the RO faucet to let it begin filling again.
8.8 * If your system has a UV filter, plug in the UV power and check to make sure the UV light
is turning on when water flows through it. The UV filter has a Flow Sensor Switch that
detects water flow and only turns the light on when needed. If the UV is not turning on
when water flows through, confirm the power source you are using has power. Typically,
the garbage disposal outlet only has power when the disposal is switched on.
8.9 The TDS (total dissolved solids) of the water should be tested periodically to verify that the
system is performing properly. iSpring RO systems have earned WQA GOLD SEAL by
exceeding the minimum requirements for NSF/ANSI standard 58 and should be giving an
average TDS reduction rate of 90%+, so if your tap water is 100ppm you should be getting
10ppm or less from the RO water (200/20>, 400/40> etc.). This reverse osmosis system
contains a replaceable treatment component, critical for the effective reduction of total
dissolved solids and that product water should be tested periodically. TDS is measured with
a TDS meter - it is an inexpensive, easy to use device that can be found on Amazon.com or
123filter.com by searching "iSpring TDS".
8.10 Check for leaks daily for the first two weeks after installation to ensure the system is
functioning properly. Install the included Flood Alarm to provide additional peace of mind
and protection.
Note: Do not use with water that is microbiologically unsafe or of unknown 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.
Congratulations, you have successfully installed your
iSpring Reverse Osmosis Water Filtration System!
Start enjoying fantastic reverse osmosis water right from your tap!
