NO FRILLS 500/800 Guide
PERFORM A FRESHWATER FLUSH TO THE RO UNIT WITH NON-CHLORINATED
FRESH WATER ONLY. EXPOSING THE MEMBRANES TO CHLORINATED WATER WILL
CAUSE IRREVERSIBLE DAMAGE AND VOID THE RO UNIT WARRANTY. THE
FRESHWATER FLUSH SYSTEM USES A CARBON FILTER INLINE BEFORE SYSTEM
TO CONSUME THE CHLORINE THAT MAY BE PRESENT FROM THE DOCK WATER.

CHEMICAL CLEANING PROCEDURE
The RO unit must be chemically cleaned when product water output drops below 80% of
original production. The frequency of this occurring will vary greatly upon feed water. Fouling
odor from the membrane will naturally occur during regular usage of the RO unit. The fouling
odor will progress without proper cleaning of the membranes, therefore reducing the
efficiency of the RO unit.
THE USE OF CHEMICALS OR CLEANING METHODS OTHER THAN THOSE OUTLINED
IN THIS MANUAL WILL VOID THE RO UNIT WARRANTY. NON-IONIC SURFACTANTS
USED FOR MEMBRANE CLEANING OR ANY OTHER CHEMICALS NOT APPROVED IN
WRITING BY PUREWATER, WILL VOID THE RO UNIT WARRANTY.
CLEANING CHEMICAL #1 IS AN ALKALINE DETERGENT, USED TO REMOVE OIL,
GREASE, BIOLOGICAL MATTER, AND GRIME FROM THE SURFACE OF THE RO
MEMBRANES. SEE WARNING LABEL ON SIDE OF PACKAGE AND OBSERVE ALL
SAFETY PRECAUTIONS ON LABEL.
CLEANING CHEMICAL #2 IS AN ACID, A MINERAL SCALE REMOVER. SEE WARNING
LABEL ON SIDE OF PACKAGE AND OBSERVE ALL SAFETY PRECAUTIONS ON
LABEL.
NOTE: All cleaning and preservation procedures can be done with either NON-
CHLORINATED freshwater to optimize performance of cleaning process, or see water.
NOTE: You should
allow your unit’s product water to run and drain for the first 30
minutes after cleaning or upon start up after preservation.
