Page 11: Section 4, Ro+ Startup & Operation
SECTION 4, RO+ STARTUP & OPERATION 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. Feed water to RO must not contain chlorine, iron, manganese, oil, or large quantities of organic matter. -
Page 12: Start-Up
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. 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). -
Page 13: System Shutdown
Allow the RO to run for 30 minutes to allow components to fill with water, purge trapped air and to rinse the membranes. Begin to close the Reject throttle valve and adjust to a 50:50 ratio flow through the Reject flowmeter compared to the Product flowmeter. Continually watch the pump pressure gauge located at the inlet of the 1 membrane and keep adjusted to around 150 PSI. -

Page 16: Controller Operation
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. - Page 17 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.
- Page 18 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.

TO DISPLAY OR CHANGE SETPOINTS NOTE: Please contact your AmeriWater representative prior to changing set points. 1. Refer to Figure 5.1 for the location of the keys used to display or change the Setpoints and Figure 5.2 for the location of the write protect jumper, J3. For the unit to be able to accept a change in a Setpoint, the shorting jumper must be in the WRITE PROTECT OFF position (center and left pins). -
Page 26: Section 6, Maintenance
MAINTAINING THE SYSTEM A Startup Log for the RO+ system has been provided by AmeriWater in Section 4.4. This must be filled out completely each time the system is used. The hardness of the inlet water should be checked daily. If this is above 0.5 grains, the membrane will foul. -
Page 27: Hro Filter Exchange
An alternative to changing the membranes when their performance degrades would be to clean them using AmeriWater’s optional clean-in-place (CIP) system. Doing so will extend the life of the membranes and reduce the frequency of membrane exchanges. -
Page 28: Hro Membrane Exchange
HRO MEMBRANE EXCHANGE Prepare the system as per the instructions in section 6.2. Loosen the Victaulic fittings on the inlet portion of the housing. This will allow the water to drain. Loosen the union for the product water. Remove the clamps that hold this membrane to the skid. Pull the quick release spring on the cap to allow removal of the end caps. -

When disconnecting or connecting any board or accessory, be sure power is unplugged. Before contacting AmeriWater for technical help, verify the programming of all Setpoints, Check the display and the status of all lights and indicators. The more information available when you contact us, the easier it will be to determine the source of the problem. - Page 32 PROBLEM INVESTIGATION CORRECTIVE ACTION RO Pump Will Not Operate Is the system in standby? (Cont.) If no, are any shut down conditions active? If no, is the RO LED, DS6 lit? If no, replace the board. If yes, with a voltmeter, verify If no, replace the board.

Route wiring from valve into the controller. Secure the wires to their respective terminals. Return the RO to service. Check for leaks around the solenoid valve that was replaced. CONTROLLER REPLACEMENT Prepare the RO per section 6.2. Note the position of all of the wiring leading into the control box. Remove the wires from their respective terminals. -
Page 35: Pump Replacement
PUMP REPLACEMENT Prepare the RO per section 6.2. Open the controller and trace the existing pump power cord. Note the position of the power cord in the terminals on the motor contactor. Remove the existing pump power connections from the motor contactor. Loosen the strain relief to allow the cord to be pulled free. -
