Troubleshooting

Correction: If the water supply contains more than 2.0 ppm of chlorine,
additional filtering of the water supply to the Reverse Osmosis
is needed. Contact your local water supplier. Correct this condi-
tion before doing maintenance on the Reverse Osmosis system.
Correction: Replace the prefilter, postfilter and Reverse Osmosis membrane
cartridges. See page 19.
Correction: Replace the postfilter cartridge. If taste and odor persist, replace
the prefilter cartridge and Reverse Osmosis membrane car-
tridge. See page 19.
tridges. See page 15.
Correction: Sanitize entire system. Call 1-866-986-3223 for instructions.
Correction: Increase water pressure, precondition the water, etc., as need-
ed to conform before doing maintenance on the Reverse
Osmosis system.
Correction: Replace the prefilter cartridge. If rate does not increase, replace
the postfilter cartridge and Reverse Osmosis membrane car-
tridge. See page 19.
Correction: Open Reverse Osmosis faucet and drain tank until flow slows to
a drip. Keep faucet open and check tank pressure. If low, pres-
surize to 6 psi. Close faucet to refill the tank.
Correction: Increase water pressure, precondition the water, etc., as need-
ed to conform before doing maintenance on the Reverse
Osmosis system.
Correction: Send treated and untreated water samples to a water analysis
lab for testing. It is important to test both the treated and
untreated water to determine system performance. If the TDS is
not within the system's performance guidelines, replace the pre-
filter, post filter and RO membrane cartridges.
Correction: Replace drain flow control insert. See page 20.
Correction: Make sure flow control insert is in place. See page 20.
Correction: Inspect and eliminate restriction or plug. Check that drain line is
routed properly. Refer to installation instructions for proper drain
connection. See pages 5 & 9.
Correction: Replace with new battery. See page 20.
Correction: Install battery correctly. See page 12 or 20.
Correction: Cut tubing square. See pages 13 & 14.
Correction: Push tubing in all the way. See pages 13 & 14.
Correction: Remove tube from connection. Remove nicked portion by cut-
ting tube to shorter length. Reinsert in connection. See pages
13 & 14. If removing the drain line, leave in place the elbow
fitting that it connects to. See page 20.
Correction: Remove tube from connection. Remove problem area by cutting
tube to shorter length. Reinsert in connection. See pages 13 &
14. If removing the drain line, leave in place the elbow fitting
that it connects to. See page 20.
