BWS1500 System Installation, Operation & Maintenance

seasonal changes in water quality, and municipal source
blending practices. To assure maintaining your target TDS
range year-round we recommend periodically checking the
“IN” TDS and making adjustments as needed.
Optimized Water TDS - Blending Adjustment
1. Allow the system to operate for at least 5 minutes before
continuing to Step 2.
2. Push the purple “POWER” button on the Water
Quality Monitor located on the upper left corner. It will
immediately display the “IN” or Optimized Water - TDS
(Total Dissolved Solids) in PPM (parts per million). By
adjusting the blend valve you are able to change the
“IN” TDS to the desired Target Range.
3. Within 30 seconds, push the “OUT” button to display the
Permeate Water TDS (from the RO membrane).
4. If the “IN” TDS is outside of the desired range:
• Turn the Blending Valve knob counter-clockwise to
open the Blending Valve, increasing the amount of
Filtered Water blending with the RO water, thereby
increasing the TDS of the Optimized Water.
• Turn the Blending Valve know clockwise to close the
Blending Valve, decreasing the amount of Filtered
Water blending with the RO water, thereby decreasing
the TDS of the Optimized Water.
5. Once the desired TDS is obtained allow the system
to run for several minutes, periodically checking the
“IN” TDS. Make smaller incremental adjustments as
necessary until the TDS “Target” is achieved.
Complete the Installation
Transition to Owner/Operator
The FINAL STEP is to meet with the Owner/Operator,
familiarize them with the system and complete the
Post-
Installation Check List
.
The system is now in “normal operating” mode and
the storage tank will fill with Optimized Water from the
Processor. Complete the
“Post Installation Checklist”
to
Confirm Normal Operation and System Settings
.
Allow the storage tank to fill before beginning operation
of the connected equipment.
Emergency Bypass Operation
The System Bypass is used for any interruption of Optimized
Water flow (such as filter change or component failure), to
bypass the processor and RP assembly and allow flow of
tap water to the equipment. To place the system in Bypass
mode, place the Bypass Switch on the Controller in the
“System Disable” position to turn off the Processor Pump.
Unplug or turn off the RP Pump. Turn the Emergency Bypass
Valve on the Processor to the “System Bypass” position.
When normal operation is restored, toggle the Bypass
Switch, plug in/turn on the RP Pump, and turn the Bypass
Valve to the “Service” position.
What are all those parts and what do they do?
This section will give you an overview of how the
system works. Refer to diagram on following page.
•
Incoming water is filtered by the prefilters (1), which
remove sediment, chlorine and organics.
•
When the Emergency Bypass Valve (2) is in the normal
SERVICE mode, water flows through the Processor.
When the Bypass Valve (2) is in System Bypass mode,
the water is diverted directly out to the equipment,
bypassing both the Processor and the Tank/RP Pump.
•
When water in the Storage Tank (3) is at a low storage
level, the High Level Float Switch (4) drops, causing the
Switch to close, causing the Solenoid Valve (5) in the
Processor to open and allowing filtered water to flow
through the Processor. The Pressure Switch (6) closes
when there is sufficient water pressure to operate the
system, allowing the Pump (7) to operate, pressurizing
the water flowing to the Membrane (8). The Membrane
feed water pressure is indicated by the Operating
Pressure Gauge (9). Some filtered water is also diverted
away through the Blending Valve (10).
•
The water flowing to the Membrane (8) is split by the
Membrane into a pure water stream (“permeate”) and
a reject water stream. The Pressure Regulator Valve
(11) allows some of the reject water to recirculate back
to the Pump (7). The rest of the reject water, controlled
by the Reject Flow Control Valve (12), flows out to the
drain. Recirculating a portion of the reject water causes
a higher flow velocity through the Membrane, serving to
clean the Membrane surface and increase Membrane
life.
•
The pure water stream from the Membrane continues
through the Permeate Check Valve (13), blends with the
metered filtered water from the Blending Valve (10) to
create an Optimized water stream which then goes on to
the Storage Tank (3) through the Tank Inlet Divert Valve
(14) on top of the Tank. Air in the tank is displaced by
the incoming water and vented out of the Sub-Micron Air
Breather (15).
•
When the tank completely fills, the High Level Float
Switch (4) rises, causing the switch to open, causing the
Solenoid Valve (5) to close, stopping the flow through
the Processor.
•
When the “IN” button is actuated on the Water Quality
Monitor (16), it measures the TDS of the Optimized
Water in the Optimized Water Line going to the storage
tank. When the “OUT” button is actuated, the Water
Quality Monitor (16) indicates the TDS of the pure water
