Troubleshooting
Problem: Chlorine taste and/or odor in the RO product water.
Cause:
The level of chlorine in your water supply
exceeds maximum limits, and has
destroyed the Reverse Osmosis mem-
brane.
Correction:
If the water supply contains more than 2.0 ppm of chlorine, addition-
al filtering of the water supply to the Reverse Osmosis is needed.
Contact your local water supplier. Correct this condition before doing
maintenance on the Reverse Osmosis system.
Cause:
The prefilter is no longer removing chlo-
rine from the water supply.
Correction:
Replace the prefilter, postfilter and Reverse Osmosis membrane
cartridges.
See Page 20.
Problem: Other taste and/or odor.
Cause:
Cause:
Postfilter expended.
Reverse Osmosis membrane cartridge
expended.
Correction:
Replace the postfilter cartridge. If taste and odor persist, replace the
prefilter cartridge and Reverse Osmosis membrane cartridge.
See
Page 20.
Cause:
Contamination in product water storage tank.
Correction:
Use sanitizing procedures. Replace prefilter and postfilter cartridges.
See page 16.
Cause:
System contamination.
Correction:
Sanitize entire system. Call 1-800-693-1138 for instructions.
Problem: System makes product water too slowly.
Cause:
Water supply to the Reverse Osmosis sys-
tem not within specifications.
Correction:
Increase water pressure, precondition the water, etc., as needed to
conform before doing maintenance on the Reverse Osmosis sys-
tem.
Cause:
Prefilter or Reverse Osmosis membrane
cartridges plugged with sediment.
Correction:
Replace the prefilter cartridge. If rate does not increase, replace the
postfilter cartridge and Reverse Osmosis membrane cartridge.
See
Page 20.
Problem: System makes lower amount of product water than usual.
Cause:
Storage tank air-charge less than
5-7 psi.
Correction:
Open Reverse Osmosis faucet and drain tank until flow slows to a
drip. Keep faucet open and check tank pressure. If low, pressurize
to 6 psi. Close faucet to refill the tank.
Problem: High total dissolved solids (TDS) in product water
Cause:
Water supply to the Reverse Osmosis sys-
tem not within specifications.
Correction:
Increase water pressure, precondition the water, etc., as needed to
conform before doing maintenance on the Reverse Osmosis sys-
tem.
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 prefilter, post filter and
RO membrane cartridges.
Cause:
Plugged drain flow control insert.
Correction:
Replace drain flow control insert.
See page 21.
Problem: Continual water flow to drain and low or no water production.
Cause:
Missing flow control insert in drain port.
Correction:
Make sure flow control insert is in place.
See page 21.
Problem: Faucet LED indicator light does not function after battery change.
Cause:
Battery dead.
Correction:
Replace with new battery.
See Page 21.
Cause:
Battery installed incorrectly.
Correction:
Reinstall battery correctly.
See Page 13 or 21.
