Pentair Everpure BWS350 Reverse Osmosis (RO) System with Tank

Introduction

General Information

• The system must be installed indoors and easily accessed for service and maintenance.
• Use cold water only, with a minimum pressure of 50 psi and a maximum of 80 psi.
• A 1/2" water supply with a full flow ball valve, pressure gauge, drain, and a 120VAC power supply is required within four (4) feet of the installation location.
• Installation must conform to all local codes and regulations.
• Keep tubing and hoses as short as possible, avoiding loops or kinks. Do not cut tubing with wire crimpers or dikes.
• Install the system as close as possible to the equipment it will serve.
• Never restrict the flow of water from the system to the drain during operation, as this flow is necessary to carry contaminants away from the membrane.

Connection - Instant Fittings Quick Assembly

Quick Assembly Steps:

1. Ensure the tubing has a clean, square-cut edge.
2. Push the tubing into the fitting until it stops; the fitting provides instantaneous holding and sealing.
3. Gently pull the tubing to confirm it is securely gripped.

Disconnection

Disconnection Steps:

1. Make sure there is no water flow.
2. Depress the manual push button on the fitting and pull the tube out.

Installing or Replacing QT Cartridges

Note: Before installing or replacing QT cartridges, ensure the plugs in the QT heads are removed.

1. Close the feed water valve.
2. Twist and pull down to remove existing cartridges.
3. Align the upward-pointing arrow on the new cartridge with the upward-pointing arrow on the head. Push the cartridge up into the head until it stops.
4. Turn the cartridge to the right until it stops. (Note: labels might not always face forward).
5. Open the feed water valve.

Installation

1. Mount the Processor

Select a secure mount location with access to the water supply, drain, and a 120VAC power supply. Attach the water processor using the upper and lower keyhole mounts. DO NOT PLUG IN THE UNIT YET.

2. Make the Drain Connection

Connect 1/4" black tubing from the processor's reject water outlet [B] to an approved air gap [C], and then connect it to the drain line.

3. Make the Processor to Storage Tank Connection

Connect 3/8" blue tubing to the processor's optimized water to storage tank outlet [D].

4. Make the Storage Tank to Processor Connection

Connect a 1/2" ID gray hose to a 1/2" hose barb adapter and clamp. Then, connect this to the tank repressurization return [E]. Route the gray hose to the optimized water storage tank.

5. Make the Optimized Water Outlet Connection

Connect a 1/2" ID gray hose to a 1/2" hose barb adapter and clamp. Then, connect this to the optimized water outlet [F]. The optimized water line will be connected directly to the equipment, or to an optional post-treatment filter, and then on to the equipment. DO NOT CONNECT THE LINE TO THE EQUIPMENT AT THIS TIME.

6. Install Membrane and Pre-Filter Cartridges

AMS-QT Membrane: Install the AMS-QT membrane into the QT head and turn to align arrows. Remove the plug from the elbow at the bottom of the AMS-QT cartridge by pushing in the gray collar and pulling the plug.

Reject Tubing: Connect 1/2" black reject tubing.

CTO-Q Cartridges: Install two (2) CTO-Q cartridges into the QT heads 1 and 2, starting from the left side of the processor, and turn to align arrows.

MA-Q15 Mineral Cartridge: Install the MA-Q15 mineral cartridge in the same manner into the fourth (far right) head.

An overall view shows the completed installation with all cartridges in place.

7. Make the Float Switch Connection

Connect the tank switch cable connector. Do NOT connect the pump to power until the tank is at least half full of water.

System Start-Up

1. Purge Air and Flush System

Step A: Turn the emergency bypass valve to the "System Bypass" mode. While holding the optimized water line over a drain, turn on the water supply valve (user supplied). Allow the system to flush until water runs clear and is free of air.

Step B: Turn the emergency bypass valve to the "Service" mode and plug in the processor. Allow the pre-filters and the membrane to purge air and flush.

Step C: After several minutes, water will start flowing to the drain, and the optimized water will begin filling the tank. (Optimized water flow rate is less than 0.25 gpm).

2. Check the Tank Float Switch and Set the Blend TDS

Check Float Switch: Remove the tank lid, raise the float (point upward), and listen for the solenoid valve to click off. Watch for water flow to the tank and drain to stop. Lower the float to resume normal operation.

Set Blend TDS: Set the blending valve to the desired optimized water TDS. Turn on power to the water quality indicator. Press the "IN" button to determine optimized water TDS. Adjust the blending valve to the user-specified TDS. Make 1/2 turn adjustments and wait 30 seconds for the TDS meter to respond.

3. Rapid Fill the Storage Tank

VERY IMPORTANT: PRIME THE REPRESSURIZATION (RP) PUMP before connecting the optimized water line to equipment. To prime the RP pump, the storage tank must be at least half full.

Step A: While holding the optimized water line over the tank opening, turn the emergency bypass valve to the "Bypass" position.

Step B: DO NOT PLUG IN THE PUMP AT THIS TIME. Allow the tank to reach half full.

Step C: When the tank is half full, turn the emergency bypass valve to the "Service" position to resume normal operation.

System Start-Up Continued

4. Prime the RP Pump

Step A: Open the buffer tank valve.

Step B: Holding the optimized water line over the tank opening, plug in the RP pump and allow it to run until the water flow is steady and free of air.

Step C: After flow is steady, close the buffer tank valve and allow the buffer tank to fill. The RP pump should turn off. If the RP pump does not turn off, it indicates air is present; repeat step 4b.

5. Make Connection to Equipment

Step A: Connect the optimized water line to post-treatment and downstream equipment.

Step B: Open the buffer tank valve and start the downstream equipment. Check for leaks.

Complete the Installation

Secure tubing, hoses, and wires as needed to ensure the installation is neat and not susceptible to damage.
