REVERSE OSMOSIS SYSTEM CARE GUIDE

MODEL NOs. 625.384720 & 625.384750

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 WateK Replace the prefilter cartridge. lithe production rate does not improve, replace the post filter car- tridge and RO membrane cartridge.

B. High Total Diaaotved Solids (TDS) in Product Water: You can get a free TDS test through some Sears retail stores or service departments. If 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 Tasteand/orOdoK Replace the prefilter, post filter and RO membrane cartridges.

CAUSECORRECTION

Chlorine taste andfor

odor in the RO product water

Other taste andfor odor

System makes product water too atowty

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.

If 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.

Increasewaterpressure, preconditionthewater, etc.,asneeded 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.
