How the Reverse Osmosis System Works
Reverse Osmosis reduces Total DissoNed Solids (TDS) and organic matter fiom wamr by diffi_sing it through a special
membrane. The membrane sepmates minerals and impmities fiom the water and they are flushed to the drain. For the
reduction of the claims specified, see Perfbmmnce Dam Sheet. High qualit T product water goes directly to the drinking
water faucet or to the storage rank. The sysmm makes a good supply of drinking wamr each day. How much it makes
depends on the feed wamr supply pressure, temperature and quality.
The prefilter and posffilter are replaceable cartridges. The carbon prefilter reduces chlorine while also filtering sediments.
The posffilter reduces any other undesirable tastes and odors before you use the _ater
These systems include an elecnonic fimcet assembly with a prefilter and poslfilter change remindel; Rexerse Osmosis
membrane change reminder and a stares okay reminder
The prefilter and poslfilter change reminder will flash amber aRer six months haxe passed or 900 gallons haxe been used.
When this occurs, it is time to replace these cartridges and sanitize the system.
The membrane change reminder flashes amber xd-len the TDS monitor in the system has measured the amount of impurities
remoxed is less than 75%. When this occm_, it is time to replace this Rexerse Osmosis membrane cartridge and sanitize the system.
Finally, a green flashing ligt_t _ill indicate the system is flmctioning properly.
Description of the Reverse Osmosis System
_Prefi/ter_Water from the cold supply pipe is directed to
the prefilter cartridge. The prefilter is a replaceahle sediment
cartridge containing activated carbon. The prefilter reduces
chlorine in the feed water because CHLORINE D ESTROYS T HE
REVERSE OSMOSIS MEMBRANE. Filtered, cleau, chlorine-reduced
water flowsfi'om the prefilter to the ReverseOsmosiscartridge.
_'_Reverse OsmosisCartridge--_he
middle cartridge includes a
tightb,' wound, special membrane. Water is forced through the
cartridge _d_ere the membrane reduces the dissolved solids m_d
orgmfic matten For the reduction of the claims specified, see
Performance Dam Sheet. High quality product water exits the
Reverse Osmosis cartridge and goes m the storage tank. Reject
wam_;,dth the dissoked solids and organic matte_; leaves the
cartridge and is discharged to the drain through 1/4" robing.
_]Postfilter--Atker leaving the storage area, but before going
to the system faucet, product water goes to the postfilter
cartridge. The postfilmr is also a replaceable sediment carnidge
that contains activated carbon. Any remaining tasms, odors or
sediments are reduced fiom product wamr by the postfilmL
Clean, high qualitT drinking wamr flows through the robing
and m the sysmm faucet.
ErJStorage Tank--The storage area holds up to 2-1l/2 gallons
of product wateL A diaphragm1 inside file tank keeps water
pressurized, when the rank is fifll, for fast flow m file fimcet
when drinking water is needed.
