Stage One: Sediment Filter
The Sediment filter reduces particulate materials such as sand, rust, and fine particles from the water
supply. This first stage also acts as a pre-filter protecting and extending the life of the following filters.
Stage Two: Pre-Carbon Plus Filter
This second stage filter significantly reduces harmful VOCs , chlorine, and soluble contaminants
which can damage the RO Membrane filter.
Stage Three: RO Membrane Filter
The RO filter works by pushing water through a semi-permeable membrane thereby separating
H2O molecules from contaminants in tap water. The powerful RO Membrane significantly reduces
pollutants such as: heavy metals, cysts, fluoride, arsenic, industrial chemicals, and more.
Stage Four: Post Carbon Block Filter
As the final stage in the filtration process, the Post Carbon Block filter further reduces any lingering
water contaminants such as chlorine and volatile organic compounds (VOCs), improving the overall
taste and odor of the dispensed water.

1. If there is an existing drain connection for a 1/4 inch quick connect tube, then use this connection.
Otherwise, locate a suitable area on the sink drain pipe to install the provided drain clamp.
NOTE: Select a location for
the drain hole based on the
design of the plumbing. It
should be installed above the
trap and on the vertical or
horizontal tail piece. Locate
the drain connection away
from the garbage disposal.
See example to the right.
2. Once a suitable spot has been selected for the drain clamp,
drill a 1/4 inch hole into one side of the pipe. Be sure to use
a suitable drill bit for the material being drilled into (for
example: PVC versus Metal Pipe) and be sure to use safety
goggles.
NOTE: Starting with the 1/8 inch drill bit, drill a 1/8 inch hole
in the drain pipe. Use the 1/4 inch drill bit to enlarge the hole.
If you do not have a 1/8 inch drill bit, then you can just use
the 1/4 inch bit. Clean the debris from the pipe and the hole
before continuing.
STEP 3: DRAIN CLAMP INSTALLATION
WARNING: this step may require drilling into the existing drain pipe. Please seek
professional help when completing this step and always wear safety protection including
safety goggles!
DO NOT drill all the way through the pipe.

During the initial purging of the system, you will hear air clearing out of the system
through the faucet along with some spurts of water. This is NOT a malfunction and is
normal operation during the very first use or when completing a filter change.
STEP 1: FLUSHING THE SYSTEM
1. Turn the provided faucet on all the way for 10 minutes to purge all the air out of the system. It is
normal for some water to flow out of the faucet during this first purge.
2. After the initial 10 minute purge, turn the provided faucet off and let the system run for 40
minutes to allow the water tank to fill for the first time.
3. After 40 minutes, turn the faucet on all the way once more for 10 minutes (or until the tank
empties) to flush the filters and the water tank.
4. Turn the faucet off.
5. The tank will fill again in approximately 40 minutes, and then filtered water will be ready to drink.
6. Record installation date on the filter change sticker chart and place sticker inside the front cover,
under the sink cabinet on the door, or another safe accessible place.

FILTER REPLACEMENT CYCLE
Contact Brondell at 888-542-3355, or visit us on the Web at www.brondell.com to order
replacement filters.
The filters are critical to the performance of the Circle Reverse Osmosis Water Filtration system, and
it is important to replace all of the filters on a regular basis. If any of the filters are overused beyond
the recommended service life, the performance of the water filtration device can deteriorate. Do not
miss the filter replacement cycle or use non-compatible filters as this can affect system performance
or damage the unit.
The LED filter change indicator in the faucet works by tracking both time and water flow from the
Circle RO system. When 6 months time or 475 gallons of water has been filtered through the system
(whichever comes first), the LED will flash red when dispensing water instead of flashing blue.
When the faucet LED indicator begins to flash red, it’s now time to change the filters and reset the
faucet indicator by replacing the battery.
Note: a new battery is always included with the RF-20 filter replacement set.
* The filter replacement cycle may be reduced for areas with poor water quality or greater use.
* The period for the filter exchange is based on an average production of 2.6 gallons of
drinking water per day.

6. After replacing filters, locate the filter change sticker chart and write down the date and filters
changed on the chart. It’s important to track each filter change since the RO filter is on a different
cycle than the other 3. Here’s the replacement cycle:
After 6 months: replace 3 filter set (RF-20) and replace faucet battery
After 12 months: replace 3 filter set (RF-20) and replace faucet battery
After 18 months: replace 3 filter set (RF-20) and replace faucet battery
After 24 months: replace 3 filter set (RF-20), the RO filter (RF-40), and replace faucet battery
Note: Brondell provides a new faucet battery replacement with each RF-20 filter set and a new
filter change sticker chart with each RF-40.
5. Install the new filter by aligning the arrow indicators on the
filter label (a) and filter base above (b) as shown then pushing
up and turning a quarter-turn counter-clockwise until the
filter stops. The filter base arrow should now point to the
“lock”arrow on the filter label. Repeat with any remaining
filters to be changed
Important: Be sure when replacing the filters that
you install the new ones in the correct location by
referring to the color coded sticker on the machine
and matching to the colored filter labels. Failure
