SOLUTION
-Check feed water line and incoming valves are open.
-Increase the water pressure by adding a booster pump.
Precondition the feed water to meet the System Specifications
(See Operating Manual).
-Replace filter cartridges.
-Inspect and remove restriction.
-It may take 2-3 hours to fill the storage tank. Low water
pressure and/or cold water temperature can reduce the
production rate.
-Back pressure from the storage tank will slow production.
Check that the air pressure in the tank is between 8-10 psi, when
the tank is empty.
-Remove and clean, or replace.
-Replace membrane element.
-Note the System's daily production rating. Low water pressure
and/or cold water temperature can reduce the production rate.
Consider a larger tank or system.
-Check that the tank shut-off valve is fully open.
-Keep lines direct and as short as possible. Increase tubing
diameter from tank to faucet.
-Add pressure to the storage tank. When the tank is empty, the
pressure should be 8-10 psi.
-The bladder inside of the storage tank may be damaged.
Replace the storage tank.
-Check that the drain line flow restrictor is installed in the drain
line connection. Also check that it has been installed correctly.
-Replace drain line flow restrictor.
-Replace drain line flow restrictor.
-This is normal
-Replace carbon filter cartridge(s).
-Replace membrane element.
-Use sanitizing procedures.
-Fill the storage tank a few times and flush to drain.
-Completely drain system and allow to refill.
-Sanitize system and tank, and replace filters and membrane.
-Check plumbing. See the flow diagram for assistance.
-If the water supply contains more the 2.0 ppm of chlorine,
additional filtering of the water supply to the system is needed.
-Replace the membrane element and filter cartridges.
-Replace if necessary.
-Replace membrane element.
-Remove membrane element and examine brine seal and o-
rings. Repair or replace.
-Do not drink the first water produced from a new membrane
element. Flush the first few tanks to drain prior to drinking.
Product water TDS may be higher until thoroughly rinsed.
-This will clear up after the system runs a few days.
-When the system is running, it is normal to hear noise from an
air gap faucet.
-Replace drain line flow restrictor.
-Remove fittings and check for damage. Replace or clean and re-
tape threads.
-Remove and check for damage. Replace if necessary.
-Inspect and eliminate restriction. Periodic inspection is
-Inspect and eliminate restriction. Periodic inspection is
recommended.
-Check for low spots and loops. Reposition if necessary.
