SECTION 4, RO+ STARTUP & OPERATION
4.1 INSTALLATION
NOTE: This entire Operations Manual should be read before operating or servicing
the RO. The Operations Manual should then be kept near the system and
used as a reference and troubleshooting guide.
1. Feed water to RO must not contain chlorine, iron, manganese, oil, or large quantities
of organic matter. Common waterworks water will normally meet these requirements.
2. Normally the water temperature must not exceed 80°F
3. The installation location must be dry and frost-free.
4. The pressure at the industrial RO inlet, when in operation, must be 20 PSI, minimum,
and must not exceed 90 PSI. If the pressure exceeds the maximum stated pressure,
or it fluctuates to pressures exceeding 90 PSI, install a pressure-reducing valve on
the inlet.
5. The flow of inlet water supplied to the RO unit shall be an uninterrupted flow at 20
PSI, minimum, and at a minimum flow rate of twice the rated Product Water flow of
the RO unit purchased.
6. A floor drain close to the unit is required that is capable of carrying away the reject
water flow for the RO unit. The reject flow is approximately the same as the rated
Product Water flow.
7. The piping, faucets, valves etc. for the Product Water outlet of the Reverse Osmosis
unit must be made of PVC or corrosion resistant stainless steel.
8. The electrical power shall be provided to the RO through a 60 amp disconnect
located near the unit. The voltage and phase must match and be verified to the RO
unit that was purchased. Control voltage is provided within the RO unit controller via
a transformer.
9. Local plumbing codes and electrical regulations must be observed and followed.

10
4.2 START-UP
Important Note: RO membranes cannot be started cold, they must be filled with feed
water and allowed to soak for a minimum of 30 minutes.
1. Connect the RO+ to your potable water supply. If blending both warm and cold water
to improve product flow rate, do not exceed 25°C (77°F).
2. Install the pre-filter cartridge(s) inside its housing (if not already factory installed).
3. The Reject To Drain hose coming out of the RO+ system is for reject water. The
water from this hose will go down the drain. Leave at least a 1” to 2” of air gap
between the hose, and the drain to prevent siphoning or reverse contamination.
4. Connect the storage tank float switch(es) into the appropriate terminal connector on
the RO‘s controller board.
5. The Product Water hose should temporarily be placed near the drain to flush any
initial impurities from the RO before connecting the Product Water hose to the point of
use or storage tank.
6. Connect the RO to its electrical power supply through the disconnect switch on the
main control enclosure. Refer to the electrical schematic for proper voltage
connections.
7. Open the RO’s feed water inlet valve located near the left side as facing the front of
the unit.
8. Turn the RO control master switch to ON that is located at the upper right on the face
of the electrical enclosure.
9. Press the RO controller switch to the ON position. An 80 second delay will occur
before the pump starts. Once pump starts, turn off RO controller and allow
membranes to fill with water with city water pressure. Let the membranes soak for a
minimum of 30 minutes.
Important Note: RO membranes can not be started cold, they must be filled with feed
water and allowed to soak for a minimum of 30 minutes.
10. Re-press the RO controller switch to the ON position. An 80 second delay will
occur before the pump starts.
11. Once the pump has started, adjust the pump throttle valve located near the
discharge of the pump to achieve a pressure at the inlet of the 1st membrane to about
150 PSI

11
12. Allow the RO to run for 30 minutes to allow components to fill with water, purge
trapped air and to rinse the membranes.
13. Begin to close the Reject throttle valve and adjust to a 50:50 ratio flow through the
Reject flowmeter compared to the Product flowmeter.
14. Continually watch the pump pressure gauge located at the inlet of the 1st membrane
and keep adjusted to around 150 PSI.
15. Once the RO has stabilized and all impurities have been flushed, the water will have
stabilized, also. Set the water quality value at the desired limit (Refer to the controller
adjustments in section 5).
16. When the RO is running stable and within desired water quality limits, Product hose
can be connected to your process water system or storage tank.
17. Make copies of the log sheet in section 4.4. Record initial operating conditions on
the Log Sheet, and then, periodically afterwards as determined by your Quality
Department or Facilities Manager. The operating conditions should be recorded at
least once each day the RO is operated.
4.3 SYSTEM SHUTDOWN
1. Press the POWER key (the display will show STANDBY).
2. Turn off the main power switch to the system.
3. Turn off the potable tap water supply to the RO.

5.2 CONTROLLER OPERATION
General Operation
The unit has 2 modes of operation, a standby mode and an operating mode that are controlled by
the POWER key. In the standby mode, the unit is effectively off. All outputs are turned off and the
display shows STANDBY. In the operating mode, the unit operates automatically. All inputs are
monitored and the outputs are controlled accordingly. Pressing the POWER key will toggle the unit
from STANDBY to OPERATE or from OPERATE to STANDBY. If power is removed from the unit,
when power is reapplied, the unit will restart in the mode it was in when power was removed.
Display
The display is a 2 line x 20-character backlit liquid crystal display. System operating status and
sensor readings are shown on this display. Set point information can, also, be shown on this
display.
Operating Status Messages
The operating status of the unit is shown on the top line of the display. The following list describes
the items shown for the operating status.
STANDBY - The unit is in the STANDBY mode.
DELAY 99 - The unit is in the RO start delay. The number is the seconds remaining before the RO
pump starts.
OPERATING - The RO unit is operating.
TANK FULL - The unit is shut down due to a tank full condition.
TANK FULL 99 - The unit is shut down due to a tank full condition. If the number is blinking, the
tank full high switch has cleared, but the tank full low switch is still active. If the number is on
steady, both tank level switches have cleared and the delay is counting down.
PRETREAT - The unit is shut down due to a pretreat lockout condition.
PRESS FAULT - The unit is shut down due to a pressure fault condition.
MEMB FLUSH 99 – Membrane Flush is active. The number is the minutes remaining in the flush
cycle.
CONDUCTIVITY
The Conductivity is shown on the top line after the unit operating status. When the unit is in
STANDBY, because of a shut down condition, the reading is replaced with ‘----’. If the reading is
over range, the reading is shown as ‘^^^^’ when in the OPERATE mode.

15
Operating Hours
The current operating hours are shown on the bottom line.
Temperature
The current water temperature is shown on the bottom line to the right of operating hours. When
the unit is in STANDBY due to a shut down condition, the reading is replaced with ‘---‘.
Warning Messages
Warning messages are also shown on the second line. If any warnings are active, the active
warnings will alternate with the normal displays for the bottom line. The following lists the warning
messages.
HI COND - The Conductivity reading has exceeded the programmed limit.
Tank Full Operation
The unit can be operated with 1 or 2 level switches. With 1 level switch, the switch is connected to
the tank full high input. When this switch has been active for 5 seconds, the unit will shut down on
tank full. TANK FULL will show on the display. When the tank full condition clears, the display will
show TANK FULL 99. The number is the tank full restart time and the unit will restart when this
delay times out.
For 2 level switch operation, the upper switch is connected to the tank full high input and the lower
switch is connected to the tank full low input. When both switches are “open”, the RO unit will start.
The RO unit will continue to run when the water level rises, and while the lower switch becomes
active (closed). When the upper switch becomes active (closes), after the 5 second delay, the RO
unit will shut down. TANK FULL will show on the display. When the tank level drops and the upper
level switch clears, the display will show TANK FULL 99 and the RO unit will remain off. The
number is the tank full restart time and the number will blink until the lower level switch clears
(opens). When the lower level switch clears (opens), the number will remain steady and the RO
will restart when the delay times out.
Tank Full Restart
The tank full restart is the delay before the unit starts when a tank full condition clears. This delay
can be in minutes or in seconds. The TF Restart Setpoint selects seconds or minutes.
Tank Full Override
A timed tank full override can be initiated when the RO unit is shut down due to a tank full
condition. Pressing the Alarm Silence/Reset key for 3 seconds during a tank full condition will
enable the tank full override. The RO will start and TF OVERRIDE 9 will show on the display. The
number is the minutes remaining in the override timer. When the override times out, the unit will
return to the tank full shut down condition.

16
Pressure Fault
If the pressure fault input becomes active (closes) and stays active for the delay programmed in
the PF Delay Setpoint, the unit will shut down for a pressure fault. The display will show PRESS
FAULT, the alarm lamp will flash and the audible alarm will sound. The pressure fault can be
cleared by pressing the Alarm Silence/Reset key twice.
Auto Reset
If a pressure fault shut down occurs and the Auto Reset Setpoint is programmed to 0, the unit will
remain shut down until manually reset. If the Auto Reset Setpoint is programmed to a value greater
than 0, the unit will automatically clear the pressure fault and attempt to restart after this delay
times out.
Alarm Silence
When a shut down occurs that causes the audible alarm to sound, the alarm can be silenced by
pressing the Alarm Silence/Reset key once. The alarm will remain silenced for 3 minutes. If the
Alarm Silence Setpoint is programmed to a value other than 3, the alarm will resound after this
delay times out. Pressing the Alarm Silence/Reset key will silence the alarm and reset this delay.
Pretreat
If the pretreat input becomes active (closes) and stays active for 2 seconds, the unit will shut down
in a pretreat lockout condition. PRETREAT will show on the display and the unit will remain shut
down as long as the pretreat input is active.
High Conductivity
If the Conductivity reading exceeds the limit programmed the Cond Limit Setpoint for the delay
programmed in the Cond Delay Setpoint, the alarm lamp will light and the HI COND warning
message will show on the display. This warning will clear when the Conductivity drops below the
Setpoint.
When the High Conductivity warning message is active, the RO will alarm, until the Product water
conductivity goes back into the acceptable quality range.
Alarm Output
The Expansion I/O relay 2 has been programmed to operate as an alarm relay. The relay will
energize whenever a warning or alarm condition occurs. The relay will remain energized as long as
the warning/alarm condition is active.

17
5.3 CONTROLLER ADJUSTMENTS
Your controller has been calibrated prior to shipment and the conductivity set point has been
preset based on an analysis of your water provided at the time of sale. It may be necessary
to periodically calibrate the Conductivity. If the controller should require calibration, follow
the instructions below. Please contact AmeriWater at 800/535-5585 or 937/461-1988 if you
have any questions regarding the procedure.
CONDUCTIVITY CALIBRATION
Refer to Figure 5.2 for adjustment location (SPAN). To calibrate the Conductivity, place the
cell in a known standard solution. Adjust the span adjustment for the correct reading. If the
cell is installed, the unit can be calibrated by taking a sample from the PRODUCT TEST
PORT and testing it with a known, calibrated meter. Adjust the span control until the reading
matches the meter.
Refer to figure 5.1 for adjustment location. To calibrate the 2nd TDS / Conductivity, place the
cell in a known standard solution. Adjust the span adjustment for the correct reading. If the
cell is installed, the unit can be calibrated by taking a sample of the water and testing it with
a known, good meter. Adjust the span control until the reading matches the meter.
DISPLAY ADJUSTMENT
The display contrast can be adjusted for best viewing by adjusting control R3. This control is
located toward the upper right corner of the board, just to the left of the cell connector.
