Check Air Pressure in the Tank
Important:
Check air pressure only when tank is empty of water!
Check air pressure in the storage tank when you notice a decrease in available water from
the RO system. Air can be added with a bicycle pump using the schrader valve that is
located on the lower side of the tank behind a blue plastic cap.
Turn off the cold water supply to the RO and unplug transformer.
Step 1

faucet still in the open position, you may add air to the tank
to purge any left over water, this will ensure that the tank is
completely empty.
Step 3
Once all water in the tank is purged, check air pressure using an air pressure gauge, it
should read between 5 - 7 PSI. (Digital air pressure gauge is recommended) Pressurize
tank using a bicycle tire pump if low. Follow start-up procedure on page 11.
Procedure for Extended Non-Use (More than 2 months)
Turn off the cold water supply to your RO system, unplug power transformer from electrical
outlet and open the RO faucet to drain the storage tank. Once the storage tank is empty,

Step 1
Reinstall reverse osmosis membrane.
Turn on the cold water supply to your RO system. Plug in the transformer,
Step 2
(Check frequently over the next 24 hours to ensure no leaks are present).
Note:
If you have connected your RO system to a refrigerator / ice maker, make sure the ice

to completely fill.
Open the RO faucet and leave it open until water begins to trickle out (it will come out slowly).
Step 3
Close the RO faucet allowing the storage tank to fill with water.
Step 4
fill the tank completely depending on the production capability of the membrane, local water
temperature and water pressure.
After the Tank has filled, open the RO Faucet to flush the tank completely. You will know that
Step 5
the tank is empty when the flow rate from the RO faucet is down to a trickle. The second tank
can be used for drinking.
