REVERSE OSMOSIS SYSTEM CARE GUIDE

MODEL NO. 625.385750

1.AT LEAST every 6 months, replace the prefilter and postfilter cartridges or when yellow LED flashes.

2.Replace the RO membrane cartridge when the percent rejection of total dissolved solids (TDS) is less than shown in the specifications (see B, below) or when red LED flashes.

3.Replace the batteries once per year.

If any of the following occur before the 6 months, replace as directed.

A. Slow Making of Product Water: Replace the prefilter cartridge. tf the production rate does not improve, replace the post filter car- tridge and RO membrane cartridge.

B. High Total Dissolved Solids (TDS) in Product Water: You can get a free TDS test through some Sears retail stores or service departments, tf the store or service department does not have a TDS meter, you can 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.

C. Chlorine Taste and/or Odor: Replace the prefilter, post filter and RO membrane cartridges.

CAUSECORRECTION

Chlorine taste and/or

odor in the RO product water

Other taste and/or odor

System makes product water too slowly

System makes lower amount of product water than usual

The ppm of chlorine in your water supply exceeds maximum limits, and has de- stroyed the RO membrane.

The prefilter is no longer removing chlo- rine from the water supply.

Post filter expended.

RO membrane cartridge expended.

Contamination in product water storage.

Water supply to the RO system not within specifications.

Prefilter or RO membrane cartridges plugged with sediments.

Storage tank air-charge less than 5 - 7 psi.

Water supply to the RO system not within specifications,

RO membrane cartridge expended.

Drain side of faucet airgap (3/8" tubing) plugged, restricted, or incorrectly con- nected to drain point.

Check valve or automatic shutoff assem- bly plugged, restricted or parts worn

Batteries dead.

Batteries installed incorrectly,

Static protection of the electronic board was not discharged.

Paddlewheel jammed.

Missing flow restrictor in red drain tube or its corresponding port.

tf the water supply contains more than 2.0 ppm of chlorine, addi- tional filtering of the water supply to the RO is needed. Correct this condition before doing maintenance on the RO system.

Replace the prefilter, post filter and RO membrane cartridges.

Replace the post filter cartridge. If taste and odor persists, re- place the prefilter cartridge and RO membrane cartridge.

Use sanitizing procedures. Replace the post filter cartridge.

Increase water pressure, precondition the water, etc., as needed to conform before doing maintenance on the RO system.

Replace the prefilter cartridge. If rate does not increase, replace the postfilter cartridge and RO membrane cartridge.

Open RO 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.

Increase water pressure, precondition the water, etc., as needed to conform before doing maintenance on the RO system.

Replace the prefilter, postfilter and RO membrane cartridges, flow control, and screen.

Inspect and eliminate restriction or plug. Refer to installation instructions for proper drain connection.

Clean, repair or replace as needed.

Replace with new batteries.

tnstall batteries correctly.

Remove batteries for one minute and then reinstall.

Repair or replace paddlewheel.

Replace flow restrictor.

Note: Sanitizing is recommended after servicing inner parts of the system(see page 9).
