Pre-Filtration
The Whole House RO systems do not include pre-filtration. It is VERY important to have
pre-filtration before the RO system to ensure longevity and that damage will not occur to
the unit. A water test of the feed water is used to determine the proper pre-treatment
equipment.
NOTE: THE SYSTEM MUST BE OPERATED ON FILTERED WATER ONLY. 99.9% OF
ALL RO APPLICATIONS REQUIRE SOME FORM OF PRE-TREATMENT. SYSTEMS
OPERATED USING UNTREATED WATER WILL HAVE PREMATURE MEMBRANE
FAILURES. MEMBRANE FAILURES DUE TO IMPROPER PRE-TREATMENT ARE
NOT COVERED UNDER WARRANTY
Pump
The pump type used on the Whole House RO systems is a multi-stage centrifugal carbon
steel pump.
Follow these guidelines to ensure proper operation of the pump:
• The pump must NEVER be run dry. Operating the pump without sufficient feed water
will damage the pump.
• ALWAYS feed the pump with filtered water. The pump is susceptible to damage from
sediment and debris.
NOTE: THE FEED WATER PRESSURE MUST NOT FALL BELOW 30 PSI WHILE THE
SYSTEM IS RUNNING. THE SYSTEM WILL SHUTDOWN FOR A LOW PRESSURE
FAULT IF A PRESSURE > 30 PSI CAN NOT BE MAINTAINED. DO NOT ATTEMPT TO
ADJUST THE PRESSURE SWITCH. THE PROPER FIX FOR THIS PROBLEM IS TO
INCREASE THE FEED PRESSURE WITH A BOOSTER SYSTEM.
Membranes
The Whole House RO reverse osmosis system comes pre-loaded with Thin Film Compo-
site membranes, unless otherwise specified. General membrane element performance
characteristics are listed on the next page.
