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 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:

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 1-866-986-3223 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.
