Compact Design, Self-Contained Water Processing Unit
for Point-Of-Use or Point-Of-Entry Applications:
Easy to Install or Retrofit: Four water connections and 115VAC or 230VAC.
Easy to Maintain: Uses Industry Standard components - no more proprietary parts or sole-
sourcing. All filters and components are on the front panel for easy access.
Single membrane can be changed in minutes, no need to remove membrane housings and fittings
to change membrane.
Water conserving design features 50% recovery - produces 1 gallon of water while sending only
1 gallon to drain. Other RO systems may waste as much as 4 gallons to produce 1 gallon
of
purified water.
Many municipalities charge for water coming in as well as sewage. Not only is that
expensive but environmentally unsatisfactory, especially in drought-stricken areas.
Concentrate recirculation loop decreases membrane fouling by rapidly flushing the membrane at a
high velocity, greatly increasing membrane life.
Time-delayed inlet solenoid valve operates for several seconds before pump activates, protecting
the pump from dry starts and pump-destroying cavitation.
Low-voltage microprocessor-based control system with Auto Flush and Pump Protection.
Flushes
membrane after each use and protects pump from running dry, preventing premature pump
failure.
These systems may be engineered for use with a single reservoir, multiple storage tanks or a
bladder tank.
Liquid level controls and sediment filter are included.
* A water softener may be required in some hard water areas.
** Additional pre-treatment may be required for brackish water.

Theory of Operation: Water Production System
The storage tank (11) is a non-pressurized tank of any size. When water is withdrawn
from the tank to a point below the low-level float (or pressure switch) (12), the input
solenoid (2) is activated by the Reverse Osmosis System Controller (27). When
sufficient input pressure (as displayed on the input pressure gauge (4)) is sensed by
the input pressure switch (5), the main pump (6) and motor (7) are energized. Water
that has passed through the sediment filter (1) then flows through the low pressure
manifold (3). The pump increases the input water pressure in the membrane (8) to a
conservative 100 psi as displayed on the system pressure gauge (21).
The water is split by the membrane into two streams: a pure water stream (permeate)
and a waste water stream (concentrate). The pure water stream passes through the
product flow meter (10) and the TDS monitor (18) and then into the storage tank.
(The TDS Meter indicates the purity of the product water going into the tank and aids
in determining when the RO membrane may be failing.) The tank will fill until water
reaches the high-level float (or pressure switch) (13). This will activate the flush cycle
(covered later) and then shut the pump and motor down.
The concentrate stream is split into two streams in the high pressure manifold
(20). One stream goes to drain through the capillary tube flow restrictor (22) and
concentrate flow meter (23). The other stream goes through the pressure regulator
(24). The pressure regulator is used to adjust the system operating pressure. The
output of the pressure regulator is feed back into the input water supplying the pump.
The flush cycle, initiated by the high-level float (or pressure switch), opens the
concentrate bypass solenoid (25). This allows the concentrated waste water (as well
as any hardness or particulates that may have accumulated on the surface of the
membrane) to be rapidly flushed down the drain. After 45 seconds, the pump and
motor will spin down before the input solenoid is turned off, protecting the pump from
a starvation / cavitation condition. For the next six minutes, the pure water flush pump
(9) is activated, flooding the membrane with a pure-water bath until the fill cycle starts
over again.

Theory of Operation: Electronic Control System
The Reverse Osmosis System Controller (27) is the grey box on the front of the system.
Inside this box is a 24 VAC transformer, a power relay, and a microprocessor-based control
board. The transformer provides a safe voltage level for all control system functions. On
the front of the controller is the main power switch, system fuse (15 amp, slo-blow), and
two LEDs. The green LED blinks at a 1 second rate and indicates proper operation of the
control board. The red LED indicates error conditions. Currently, error conditions indicated
by the blinking red LED include: 1- float switch faults and, 2- low feed water input pressure.
When water is withdrawn from the tank to a point below the low-level float (or pressure
switch) (12) and the carbon filter cut-out switch is closed, the input solenoid (2) is activated.
When sufficient feed-water input pressure is sensed by the input pressure switch (5), the
control board will activate the power relay which in turn will apply power to the main pump
(6) and motor (7). The pump / motor will boost the recirculating system pressure to 100-
110 psi.
If, at any time during a fill cycle, the input pressure drops enough to de-activate the input
pressure switch, the main pump and motor will be powered down. The control board will
then attempt two more start sequences. If low input pressure is detected two more times,
the system will shut down completely and indicate the condition by the red blinking LED.
The controller will need to be powered down and a determination as to the cause of the
persistent low pressure condition will have to be made.
A normal fill cycle will terminate when the water reaches the high-level float (or pressure
switch) (13). A flush cycle will begin with the input solenoid and main pump continuing to
operate while opening the concentrate bypass solenoid (25). The flush cycle will terminate
after 45 seconds; the bypass solenoid is turned off and the pump and motor will spin down
before the input solenoid is turned off, protecting the pump from a starvation / cavitation
condition. For the next six minutes, the pure water flush pump (9) is activated, flooding the
membrane with a pure-water bath until the fill cycle starts over again.

Preventative Maintenance Standards:
To be able to properly service and maintain RO membrane systems it is important to
understand the system history, so the first time a unit is serviced there should be a system
history card filled out and attached to the machine. Knowing what the settings were after
the last service will be very helpful in understanding what is required for service in the
future.
PM Requirements - Follow the procedures in this manual and,
Quarterly:
Change all pre-filters and o-rings
Clean filter housings
Inspect system for leaks
Check all system operating pressures
Check membrane production
Check membrane water quality
Record all information in a system history log
Annually:
In addition to above, sanitize all filter housings with Kay-5
sanitizer (one packet to 2.5 gallons of warm water) or similar product.
Follow standard sanitizing procedure, clean with mild detergent, rinse
with clear water, fill filter with sanitizer solution, and allow to air
dry or reassemble. Do not rinse the parts after sanitizer solution.
Inspect the tank for any algae growth and clean with Kay-5
sanitizer if necessary.
The Need for Pre-Treatment:
RO pre-filtration should be a combination of sediment ,carbon filtration, and water
softening The sediment filter brings the feed water NTU value to < 1 and the carbon filter
further reduce the sediment & turbidity levels in your filters reducing chlorine, chloramines
and VOC levels in the water down to acceptable levels. Because of the high recovery
of the pumped RO systems we highly recommend the use of a water softener ahead
of the reverse osmosis system. This will greatly increase membrane life and reduce
maintenance costs of the RO system.

Water Purification System Start-Up
1. Close shut-off valve ahead of the pre-filter.
2. Set the carbon filter (red handle) by-pass
valve to by-pass position.
3. Turn the black manual regeneration knob
(rotate clockwise one click from the service
position) on the carbon filter control head
to the backwash position. Make sure the
carbon filter is plugged into a 120V outlet.
Now slowly turn the red by-pass valve handle
located at the back of the carbon
filter to the
service position to bleed air from tank. Do not
rapidly open this valve. Leave valve partially
open until the air has been bled from the tank.
Then fully open the valve.
4. Backwash the carbon filter for at least 15
minutes after air has been bled from the
tank and until the backwash is clear of black
carbon fines.
5. Return the carbon filter control head back
to the service position by rotating the black
manual backwash knob clockwise around to
the service position.
6.
Set time of day on the control valve on the
carbon filter by depressing the red button and
aligning the 24 hour gear to the current time.
7. On the skipper wheel, pull every third tab
outward (i.e. #1, 4, 7 and 10). This will
backwash the carbon filter every three days.
8.
Open the shut-off valve ahead of the pre-filter.
9. With RO system in the OFF position and
all plumbing and electrical connections
completed, rotate the input solenoid valve
lever to manually open the inlet solenoid
valve. The word “ON” should be visible.
10. Leave the valve open until air is purged from
the system, letting pressure build up to set
the low pressure switch.
11. Check feed water connections for any leaks.

Installation and Setup: (continued)
12. Shut the valve by turning lever to close the inlet solenoid
valve. The word “OFF” should now be visible.
13. At the control panel, turn the valve to the BYPASS
position, open all faucets and rinse the store pipes out for
10 minutes. Close all faucets. Return the control panel
valve to RUN.
14. Unplug the Delivery Pump so it will not run.
15.Turn the power switch on the control panel to the “ON”
position (UP). This will immediately open the inlet
solenoid valve. After 5 seconds, the RO pump will turn
on. This motor protection circuitry assures a flooded inlet
to the pump prior to pump start-up; eliminating dry starts
which could damage the pump.
16. After a few minutes of operation, use a 1/2” wrench to
loosen the nut on the threaded shaft of the pressure relief
valve, located beneath the high pressure manifold.
17. Adjust the pressure relief valve to 100 psi by turning the
brass handle. Rotate clockwise, when viewed from the
bottom, to increase the pressure and counter-clockwise
to decrease the pressure.
18. When adjusted to the proper pressure, lock the nut back
in place.
19.Check the product water to waste water ratio. It should
be approx. 1:1. Note: If not, contact the factory (the flow
restrictor may require adjustment).
20. Disconnect the line at the top of the Product Flow Meter.
Disconnect the drain line leaving the Tank Overflow Filter
and temporarily re-connect it to the Product Flow Meter.

.
Turn the switch on the Control Box to the up, or ON position.
22. Flush the new Mineral Additive Cartridge for 10 minutes.
23. Turn the switch on the Control Box to the down, or
OFF position.
24. Disconnect the temporary drain line at the top of the
Product Flow Meter. Re-connect the drain line to the Tank
Overflow Filter and re-connect the blue line (from the tank)
to the Product Flow Meter.
