STAGE 1 – SEDIMENT FILTER
Recommended change 3-6 months or 1,500 gallons total
or400gallonsoflteredwater
The rst stage of your RO unit is a ve micron sediment lter that traps sediment and other
particulate matter like dirt, silt and rust which will aect the taste and appearance of your water.
STAGE 2 – CARBON BLOCK FILTER
Recommended change 3-6 months or 1,500 gallons total
or400gallonsoflteredwater(at1ppmChlorine)
The second stage of your RO unit is a carbon block lter. The activated carbon in the lter
reduces chlorine and conditions the water prior to the RO membrane.
STAGE 3 – RO MEMBRANE
Recommended change 1-2 years
The RO membrane reduces impurities known as total dissolved solids (TDS) from the water
down to 1/10,000 of a micron, reducing arsenic, lead, parasitic cysts, copper and more.
Because the process of ltering the high-quality water takes time, it is common to use a storage
tank to collect ltered water, making it available on demand.
STAGE4–COLORCHANGINGRESIN(DEIONIZATION)
Model 540019 only
Replacelterwhenresinchangescolor
After the water is ltered by the membrane, there is usually a small amount of total dissolved
solids (TDS) left in the water. In certain non-drinking water applications, it is important to remove
the remaining TDS from the water. This is accomplished by ltering the water through a resin
that is charged with cation and anion resins (H+ and OH-). As the resin absorbs the TDS, it will
change color. When all resin has changed color, it is time to replace the DI lter.

WARNING: The RO Buddie will remove chlorine, but NOT chloramines. Test your water and/or
check with your local water company to find out if you have chloramines in your water.

OPERATING GUIDELINES
DO NOT
use with water that is micro-
biologically unsafe or of unknown quality
without adequate disinfection before or after
the unit.
Theoptimalwaterpressureis40-65PSI.
The supply water pressure should range
between 40-65 PSI. If the pressure is more
than 80 PSI, a pressure regulator is required.
If the water pressure is less than 40 PSI, a
booster pump is needed. The rated 50 or 100
GPD output of the RO unit is calculated using
65 PSI.
Theoptimalwatertemperatureis77°F.
Using other water temperatures will diminish
the eectiveness of the ltration and can
accelerate degradation of the membrane.
Water hardness should not exceed
10grainspergallonor170parts
per million.
Operating above this may shorten the
membrane life.
Reverseosmosislteredwatershould
not be run through a copper tube.
The pure RO water can leach copper from the
pipe, eventually leading to holes in the pipe.
DO NOT
operate the unit unattended.
