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, addi-
tional filtering of the water supply to the Reverse Osmosis is
needed. Correct this condition before doing maintenance on the
Reverse Osmosis system.
Cause: The prefilter is no longer reducing
chlorine 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 post filter cartridge. If taste and odor persists, replace
the prefilter cartridge and Reverse Osmosis membrane cartridge.
See page 20.
Cause: Contamination in product water storage
tank.
Correction: Use sanitizing procedures. Replace pre and post filter cartridge. See
pages 16 & 20.
Cause: System contamination. Correction: Sanitize entire system. Call 1-800-426-9345 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
system.
Cause: Prefilter or Reverse Osmosis mem-
brane cartridges plugged with sedi-
ments.
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, pressur-
ize 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
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 prefilter, post fil-
ter and RO membrane cartridges.
Problem: Continual water flow to drain and no product water.
Cause: Missing flow control insert in red drain tube
or its corresponding port.
Correction: Replace flow control insert. See page 21.
