valves are not permitted. Please
consult your local plumber.
The following warnings and cautions appear
throughout this manual and should be care-
fully observed.
yThis equipment is to be installed
to comply with the local plumbing
code and any other applicable code.
yWater pressure must not
exceed 100 psig (690 kPa). To
reduce water pressure, install
a water pressure regulator and
set to suit the application.
yWhen installed on metallic
plumbing, a properly sized
electrical bonding jumper must
be installed across the inlet and
outlet pipes serving this unit.
NOTE: If the inlet water pressure is
less than 50 psig (345 kPa), it is
recommended that a suitably-
sized booster system be installed
(outlet pressure 60 psig - 100
psig max/441-kPa - 690 kPa max).
Protect from becoming dry
If the membrane dries out, irreversible dam-
age to the RO membrane may result. Protect
the lter from becoming dry by keeping it
wet and sealed at all times.
Protect from freezing
If the RO membrane freezes during opera-
tion or storage, irreversible damage to the
membrane and brittle cracking of the
cartridge or housing may result.
Protect from direct sunlight or other UV
sources
Avoid long-term exposure to direct sunlight
or other UV sources. The RO should be
stored in a dark location.
Protect from high temperatures or
abrupt variation in temperature
The maximum operating temperature is
100°F (38°C). Avoid abrupt variations in tem-
perature. Any temperature variation should
be made slowly.
Protect from rough handling or dropping
Mechanical damage, external breakage,
and/or internal breakage of the lter can
result if the system is dropped or bumped.
Handle with care at all times during trans-
portation and installation.
Protect from organic solvents and
concentrated acids
Prevent any and all contact of the mem-
brane with strong solvents, solvents
containing chlorine, or concentrated acids.
Do NOT use strong solvents or concen-
trated acids on any plastic parts of the
lter system. Examples of some solvents to
avoid: acetone, methyl acetate (nail polish
remover); hexane (spot removers); turpen-
tine, toluene (paint thinners); dry cleaning
solutions, insecticides.
Protect from abrasive material
The membranes must be protected from
abrasive materials like shavings left in a
pipe. Abrasive materials in contact with the
membrane can cause irreversible damage
to the membrane. All pipes must be ushed
clean before installing the lter. All plastic
parts of the lter system must be protected
from sharp objects like knives, sand paper,
or other tools. Cutting or nicking a plastic
part can weaken it and cause a leak. Do NOT
use abrasive cleansers on any plastic parts.
Protect from water hammer
The system must be protected from shock,
pressure surges, or pulsation that may occur
inside water pipes. Water hammer occurs in
pipes when a valve or faucet shuts quickly.
Install a water hammer arrestor (pressure
vessel containing compressed air separated
from the water by a diaphragm) to reduce
pressure shock.

OPERATION
Overview
yNormal Operation Mode
During Normal Operation Mode, water
enters the Inlet and ows through the
Filter before exiting the outlet as us-
able product water.
The drain line runs continuously as
long as the system is making water.
This drain line ushes the minerals
removed by the RO membrane.
NOTE: DO NOT plug or stop the water
ow from the drain line. If this
ow is stopped, water will contin-
ued to be ltered, but the system
will not ush. This will cause the
RO membrane to plug prema-
turely and reduce the life of the
RO System.
yTank Full Mode
When the tank is full, no water
runs out of the drain line.
CAUTION
Stopping the drain ow can cause the
Filter to plug prematurely and may
reduce the life of the lter. Consult
the factory for more information. Figure 1. Bulkhead Identication

Drain Valve Connection
The drain is for ushing particle buildup out
of the system during operation. The drain
line can be installed one of two ways:
1. Install a sucient length of 1/4” OD
tubing (not supplied) from the drain
outlet on top of the RO system to the
drain.
OR
2. Using the short length of 1/4” OD
tubing, the reducing union, and
hose barb (supplied), run a sucient
length of 1/2” ID Hose (not supplied)
from the drain outlet on top of the
RO System to the drain.
Remember to use a hose clamp (not
supplied) on the hose barb tting.
When connecting the drain hose, pay atten-
tion to the following guidelines:
yThe drain line plumbing must
be able support the ow rate
when the system operates.
yThe drain line leading out of
the system must be as short as
possible and slope downwards
without any kinks or loops.
yThe drain line plumbing must
be positioned and secured at
least 2 inches above the drain
(Figure 4). This air gap protects
the system from contamination in
the event of a backed-up drain.
yThe drain used must not be
blocked or restricted.
yThe drain used must be as large or
larger than the drain line plumbing.
yThe drain line from the system
should be secured at the drain using
appropriate mounting hardware.
NOTE: The drain MUST accommodate a
ow of up to 1 gpm.

Rinsing the RO System
The RO System must be rinsed to remove
any air and protective solution before the
system is used.
NOTE: The RO System must be rinsed
TO DRAIN before use. Rinsing to
drain removes storage solution
and air.
1. Check that all tubing connections
are rmly seated. Check to see
that the cartridge retainer clips are
properly engaged and locked. Failure
to keep the retaining clip in place
will result in accidental leaks and
ooding.
2. Make sure the Tank valve is OPEN.
3. Turn on the water supply and check
for leaks.
4. Allow the system to run and the tank
to ll.
5. When the tank is full, the pump will
shut o. Leave the tank undisturbed
for at least 8 hours to ensure proper
sanitization.
6. Two hours after the inlet water is
turned on, check again for leaks,
especially at the tank and tub-
ing connections leading from the
Product water outlet to the tank.
These parts will not see full pres-
sure until 2 hours after the system is
activated.
7. After 8 hours, open the product wa-
ter valve to allow the product water
in the tank to run out to drain at
maximum ow. The initial discharge
will be dark due to the bulk of the
carbon nes being washed out.
There may be the scent of chlorinat-
ed water due to the sanitizing agent
in the tank.
8. When the ow has diminished to a
fast drip, close the valve and allow
the tank to rell. The system is ready
for use.
Sanitizing the Plumbing
The plumbing from the RO System
must be sanitized to eliminate possible
contamination that may have occurred
during the installation process.
One ounce (30 ml) of liquid chlorine bleach
(regular bleach, unscented 5.25 % - 6 %
sodium hypochlorite) or Kay-5 sanitizer
solution (Sodium Dichloro-s-Triazinetrione
Dihydrate, 6%) or equivalent can be used to
sanitize the plumbing.
The Kay-5 sanitizer solution is made by
dissolving a 1 oz. packet of Kay-5 powder
in 2 oz. (60 ml) of clean warm water. This
can be done by removing 1 inch from the
top of the Kay-5 packet and adding the 2
oz. of warm water to the packet. Mix with a
coee stirrer to dissolve. When added to the
plumbing from the RO System, this will cre-
ate a 60-100 ppm chlorine solution.
NOTE: Follow the handling and safety
instructions supplied with the
sanitizer.
1. Follow the steps in the Rinsing the
RO System section of this manual.
2. Turn o the water to the system.
3. Close the Tank valve.
4. Allow the system and plumbing to
drain by opening the line down-
stream to the RO System.
5. Disconnect the line to the equip-
ment being served at the Tee tting
and pour the sanitizer into the line
using a cup or funnel. Be careful not
to spill the sanitizer onto clothing or
skin.
6. Reattach the line to the Tee tting.
7. Slowly turn on the Tank valve and
allow water to ow through the line
and out to the equipment.
8. Let stand without water ow for at
least 15 minutes to allow time for the
pipes to be sanitized.
9. After 15 minutes without water ow,
open the line at the equipment and
allow water and sanitizer to ow un-
til the presence of sanitizer is gone.
10. Reconnect all lines and turn on water
to the RO. The system is now ready
for use.

Initial Performance Verication
After initial ush, a TDS (Total Dissolved
Solids) measurement should be taken and
recorded. This data can be used to compare
to factory test data and future system data.
Some deviations may occur due to dier-
ences in feed water TDS and temperature
Total Dissolved Solids (TDS) Rejection Test
USe a TDS meter to measure the TDS in both
the feed water and product water. Calculate
the percent rejection using the formula
below. Rejection should be 85% or better:
100 x (Feed TDS - Product TDS) / (Feed
TDS) = % Rejection
Example:
Feed TDS = 500 ppm
Product TDS = 25 ppm
100 x (500 - 25) / (500) = 95% Rejection
RO Recovery Calculation
Using a stop watch and graduated cylinder
(or other calibrated volume), measure the
product water ow rate and the drain ow
rate. The product water ow rate should
be the ow coming directly from the RO
System, not from the tank. Close the tank
valve to make this measurement. Calculate
the percent recovery using the formula
below:
100 x (Product Flow Rate) / (Product +
Drain) = % Recovery
Example:
Product Flow Rate = 25 mil/min
Drain Flow Rate = 200 ml/min
100 x (25) / (25 + 200 ) = 11.1%
Recovery
Recovery is dependent on feed water tem-
perature and pressure. Measure and record
the feed water temperature and pressure
whenever measuring the percent recovery.
Tank Pressure Switch Test
With the product water line connected to
the tank and with the system running, close
the tank valve. The pressure in the line from
the system will rise and the system should
shut o (drain ow stops).
Opening the tank valve allows the pressure
to drop in the line from the system and the
system should turn on.
SEMIANNUAL TASKS
Check Permeate Tank Air
Pre-Charge
The permeate tank air charge should be
checked every six months:
Tools and supplies required:
Air Pressure Gauge, 5-40 psi range (0.3 -
2.7 bar) with tire valve (Schrader Valve)
connection.
Source of compressed air (manual bicycle
tire pump or air compressor).
CAUTION
Air pre-charge should be checked and adjust-
ed under zero system pressure. The system
must be depressurized before checking the
tank pre-charge. Do NOT adjust the tank air
pre-charge with the system under pressure.
CAUTION
Be careful when adding air to the tank. Do
NOT add too much air pressure to the tank.
1. Refer to Figure 1. Depressurize the
system by closing the Inlet valve and
opening the Tank valve. Make sure
the Permeate Tank is fully drained.
2. Unscrew the protective cap from the
air valve on the tank.
3. Use the pressure gauge to check the
tank pre-charge for pressure.
NOTE: If any water comes out of the
air valve, the tank bladder has
ruptured and the tank needs to
be replaced.
4. The permeate tank should have a
pressure of 5-8 psi.
yTo add pressure to the permeate
tank, use a manual bicycle tire pump
or other source of compressed air.
yTo release pressure from the
permeate tank, press the center
pin on the air inlet valve.
5. Once the permeate tank is at 5-8 psi,
replace the protective cap on the air
valve.
6. Pressurize the system by opening
the Inlet and Tank valves.
