*Water output will decrease as the tank empties and will only be a quick drip or slow
stream when the tank is empty. This is normal.
**Water will run down the drain whenever the system is lling the tank. How long it
runs depends on water pressure, lter and membrane condition, membrane size,
system conguration, and amount of water taken from the tank. Average times for
relling the tank range from 30-45 minutes for a couple glasses of water up to 4-5
hours to completely ll the tank.
***The standard tank will hold a maximum of about 3.2 gallons of water, the up-
grade tank will hold about a maximum of about 10.3 gallons of water. Actual storage
capacity may be less depending on system conguration and water pressure.
Troubleshooting
Note: To remove tubing from quick connect ttings, hold in on the small col-
let ring at the end of the tting, push this ring in towards the tting while
gently pulling out on the tubing. This releases the tubing from the tting and
it will slide out easily
