Solutions For Life

SANITIZING THE SYSTEM

1. Remove black rubber "O"-rings from grooves in housings. Wipe grooves
and "O"-rings clean, set "O"-rings aside for now.
2. Rinse out bottom of housings and fill each 1/3 full with water. Add 2
tablespoons of house-hold bleach to each housing and scrub cap, bottom
of housings and the membrane housing with a non-abrasive brush or
sponge. Rinse thoroughly
3. Lubricate each "O"-ring with a coating of clean silicone grease. With two
fingers press each "O"-ring securely into the groove below the threads of
the appropriate housing.
CAUTION
The rubber "O"-ring provides the water tight seal between the cap and the
bottom sump. It is important that the "O"-ring be properly seated in the groove
below the threads of the housing or a leak may occur.
4. Screw bottom of housing onto caps WITHOUT inserting filters and hand-
tighten. Do not over-tighten.
5. Open the cold water supply and let system run for 2-3 minutes to
carry the bleach solution throughout the system.
6. Close the cold water supply and turn on the drinking water faucet.
Let the faucet run for about 30 seconds before turning off.
7. Let the entire system stand for 30 minutes to sanitize.
8. After 30 minutes, turn on the drinking water faucet to allow the
bleach water to rinse out (about 3-5 minutes).
9. Unscrew bottom of housings, discard any water and rinse with fresh
water.
REPLACING THE MEMBRANE & FILTERS
To replace filters, see Replacing the Pre-Filters and Post-Filter on page 8.
To replace the membrane, see illustration #10 below.
NOTE: After installing new membrane and filters, allow the system to run for
three hours to fill tank. Check system for leaks periodically. As the storage
tank builds pressure, leak may occur that were not present initially.
When membrane and filters have been changed, follow the instructions for
system start-up procedure Step #11 System Start-Up.

TROUBLESHOOTING GUIDE

Leaks Between Bottom of Housing and Cap
1. Ensure sump is tightly screwed to cap. If it leaks, close the cold water
supply and the tank valve.
2. Clean black rubber "O"-ring and lubricate with clean silicone grease. With
two fingers, insert "O"-ring in groove below threads of housing and press
into place. Tighten housing back onto cap.
3. Open cold water supply and tank valve.
If leak persists, call Technical Support.
Leaks on Tank Valve Assembly
1. Open drinking water faucet to drain storage tank. Let drinking water faucet
run until it drips. Turn off cold water supply.
2. Push in on white collar of tank valve fitting and pull out on tubing. Unscrew
the tank valve from storage tank. Rewrap threads on top of tank with at
least 5-8 wraps of plumbers tape. Screw tank valve back onto tank. Trim
1/2" from end of tubing and reinsert 5/8" back into tank valve fitting.
3. Open the cold water supply and tank valve and close the drinking water
faucet. Let system pressurize for several hours and check for leaks. Check
for leaks again after the tank is full.
Leaks on Quick-Connect Fitting
1. Close the cold water supply and tank valve.
2. Depress plastic collar and pull out tubing.
3. Cut off 1/2" of tubing and place mark 5/8" from end of tubing. Tubing
should be cut squarely. The internal and external burrs should be removed.
4. Push in tubing 5/8" into fitting.
5. Open the cold water supply and tank valve. If leak persists, call Technical
Support.
No Flow or Slow Flow from the Brine (Drain) Line
Less than 1 1/2 cups per minute.
NOTE: Before checking brine (or reject) flow, make sure the system is
producing water by turning off the tank valve and opening the faucet. Water
should drip from faucet.
1. Examine the pre-filters. If clogged, replace and recheck the brine (or drain)
flow rate.
2. If the pre-filter are not at fault, the brine (or reject) flow controller is
probably clogged.
High TDS in Product Water
If high levels of TDS (Total Dissolved Solids) are detected in your product
water (approximately 30% or greater of what is measured in your tap water,
as determined with a conductivity meter), the RO membrane may need to be
replaced, or the brine (or drain) flow control tubing may be clogged. See your
dealer or plumber to test product water TDS.
Reduced Production
Slow or no product water flow usually indicates either a clogged pre-filter or
an exhausted membrane. First, replace the pre-filters. If the production rate is
not improved, replace membrane.
Gradual Return of Taste and Odor
Gradual return of unpleasant taste and odor over a period of time may
indicate that your filter cartridges and/or membrane need to be replaced. See
"Replacing the Pre-Filters and Replacing RO Membrane".
Sudden Return of Taste and Odor
If shortly after complete servicing noticeable taste and odors return contact
Technical Support.
No Water Pressure from the Drinking Water Faucet or Low Volume in
Storage Tank
1. Close the cold water supply to system.
2. Lift storage tank to see if it is empty. If not, open drinking water faucet to
empty water from tank.
3. When the tank is empty, use a pressure gauge to check the air pressure in
the tank. An empty tank should contain approximately 7 to 10 psi pressure
in the tank. Increase or decrease the air in the tank accordingly.
4. Open cold water supply. Let system run for 3 hours to fill tank, then check
performance.
NOTE: it may be necessary to pump a small amount of air into the tank with
a bicycle pump to remove all the water from the tank.
