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 membrane.
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.
Cause:
The prefilter is no longer reducing chlorine
from the water supply.
Correction:
Replace the prefilter, postfilter and Reverse Osmosis membrane
cartridges.
See page 19.
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 car-
tridge.
See page 19.
Cause:
Contamination in product water storage tank.
Correction:
Use sanitizing procedures. Replace prefilter and postfilter car-
tridges.
See page 15.
Cause:
System contamination.
Correction:
Sanitize entire system. Call 1-800-689-4571 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 need-
ed to conform before doing maintenance on the Reverse
Osmosis system.
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 car-
tridge.
See page 19.
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, pres-
surize 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 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.
Cause:
Plugged drain flow control insert.
Correction:
Replace drain flow control insert.
See page 20.
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 20.
Problem: Water leaking from faucet airgap hole.
Cause:
Drain side of faucet airgap (3/8” black tub-
ing) plugged, restricted or incorrectly con-
nected to drain point.
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.
Problem: Faucet LED indicator light does not function after battery change.
Cause:
Battery dead.
Correction:
Replace with new battery.
See page 20.
Cause:
Battery installed incorrectly.
Correction:
Install battery correctly.
See page 12 or 20.
Problem: Water leaks at push connect fittings.
Cause:
Tubing not cut square.
Correction:
Cut tubing square.
See pages 13 & 14.
Cause:
Tubing not pushed in all the way.
Correction:
Push tubing in all the way.
See pages 13 & 14.
Cause:
Tubing nicked.
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.
Cause:
Outer tubing surface finish not smooth.
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.
