Filter and RO Membrane Storage
1.
Store unopened filters in an airtight container to prevent them from absorbing air. This prolongs the
shelf life of the filters and avoids any possible odors or contamination from the air.
2.
Store in a cool, dry, dark place (avoid heat and moisture contamination). Using this method it is okay
to store filters for several years.
Extended System Non-Use
-
If you will not be using the RO System for two weeks or more, please read the chapter “Vacation Mode”.
How to Change the Pre-filter Housing
(Recommended about every 3 months, depending on water use)
1.
You will need a clean cloth, dish soap, and 20” PP Cartridge – 5um filter. (The system may release water
when it is disassembled.)
2.
Turn off the water supply connected to the RO System, the Feed Water Adapter Valve, and the Tank
Valve [if you are using a tank]. Then open your pure water outflow to release pressure,
3.
Unscrew the Filter Housing using the Filter Housing Wrench. Remove old filters and dispose of them.
4.
Wash the Pre-filter Housings with dish soap then proceed to rinse until all soap is removed.
5.
Ensure that your hands are washed clean before unwrapping the new filter. After unwrapping, place
the new filter inside the housing. Make sure the Housing has an O-Ring firmly in place in the Housing’s
lower groove (just below the threading). Tighten the Pre-filter Housing using the Filter Housing
Wrench. Do not overtighten.
6.
Restarting the system.
