Check Air Pressure In The Tank; Procedure For Extended Non-Use - Watts Premier WP-5 Installation, Operation And Maintanance Manual

Check Air Pressure in the Tank

Note:
Check air pressure when tank is empty of water!
Check air pressure in the tank when you notice a decrease in
available water from the RO system.
It is recommended that you drain the tank of water, and then
Step 1
pump up the RO tank in order to ensure all water is out of the
tank. Air can be added with a bicycle pump.
Once all water in the tank is purged out, check air pressure of the
Step 2
tank. If you added air to the tank, it will be higher than 5 - 7 psi.
Allow air out until you have 5 - 7 psi in the tank.
Procedure extended for Non-Use
If the system will not be used for an extended period (more than 2
months), shut the system down and remove the membrane. Place
the membrane in a sealed plastic bag with a few drops of RO water
and place in your refrigerator.
For restart, follow annual sanitization procedures.
