BWS1500/175 HIGH FLOW INSTALLATION DIAGRAM
Installing or Replacing QT Cartridges
NOTE: Before installing or replacing QT cartridges, make sure to remove the plugs in the QT heads.
-
Close feed water valve.
-
Twist and pull down to remove cartridges.
-
Align the upward-pointing arrow on the new cartridge with the upward-pointing arrow on the head. Push cartridge up into head until it stops.
-
Turn to right until it stops.
NOTE: labels might not always face forward. -
Open feed water valve.
INTRODUCTION
General Information
- The system must be installed indoors and easily accessed for service and maintenance.
- Use cold water only at a minimum of 45 psi and a maximum of 80 psi.
- Distribution plumbing from the system to equipment location(s) should be minimum ¾” nominal.
- Hose, PEX, or other non-metal pipe is recommended.
- Cut tubing and hoses to an appropriate length.
- Avoid loops or kinks in tubing.
- Do not cut tubing with wire crimpers or dikes.
- Route and secure lines in an orderly manner.
- Installation must conform to all local codes and regulations.
Equipment Layout
Take time to visualize the final placement of equipment. Hose, tubing and
electrical connections will be made between the processor, storage tank,
depressurization (RP) pump, buffer tank and the distribution
plumbing.\Consider the placement of components in relation to the utilities
(described below), and allow easy access for operation and service. For
example, make sure that an operator can see and access the emergency bypass
valve on the left side of the processor; and that the power cords from the
processor and RP pump can be routed to the power outlet.
Utility Requirements
Water Supply A minimum ½” dedicated water supply line* with ½” NFPT full-
flow ball valve is required within six (6) feet of the processor. When
possible, locate the supply valve to the left of the processor and install a
pressure gauge. Drain A drain with a capacity of four (4) gallons per minute
flow is required within four (4) feet of installation location. Power Two
(2) 120 VAC electrical outlets are required; one for the processor and one for
the RP pump.
*NOTE: A dedicated supply line is a water line that runs directly from the main water source. It does not branch out and is uninterrupted along its path.
INSTALLATION
-
Prepare the Components
-
Mount Processor
-
Make the Feed Water Connection
-
Make the Drain Connection
-
Make the Processor to Storage Tank Connection
-
Make the Storage Tank to RP pump and Buffer Tank Connections.
NOTE: The RP pump must be located on the floor near the storage tank or on a stand no more than 8″ above the bottom of the tank.
A. Connect the 1″ grey hose to tank outlet and secure with large clamp.
B. Cut hose to length and connect other end with clamp to RP pump inlet.
C. Connect the 3/4″ hose to RP pump outlet and secure with clamp.
D. Connect the other end to inlet of buffer tank and secure with clamp.
-
Make the Buffer Tank Outlet to Processor Connection
-
Make the Optimized-Water-Line Connection to the Processor
A. Attach ½” hose barb adapter with the clamp to ½” grey hose and connect to optimized water to equipment connection on processor. (The other end will later be connected to the distribution plumbing that supplies equipment.)
-
Install Filter and Mineral Addition Cartridges
-
Make the Storage Tank Float Switch Connection
SYSTEM START-UP
11. Purge Air and Flush System
D. Open Feed Water Supply Valve
E. Plug in the processor power cord at this time.
F. The controller will power up, but will be in “system disabled” mode
(indicated by “tank full” LED flashing red). To enable the system, press and
hold the “system disable button” until you hear a click, then release. The
“inlet solenoid valve” LED will illuminate.
Water will begin to flow through the system. In approximately 30 seconds, the
processor pump will start. Allow filters and the membrane to purge air. Water
will begin flowing to the drain and through the blue optimized water line to
the storage tank.
12. Check Tank Float Switch
13. Rapid-Fill the Storage Tank
14. Prime the RP Pump
15. Adjust the Blend TDS
D. Make single-turn adjustments, waiting 30 seconds between, until the TDS is
at the desired level.
E. After five (5) minutes, re-check the TDS and make final adjustments if
necessary.
16. Make Connection to Equipment and Complete the Installation
A. Connect optimized water line to post-treatment (if used) and downstream
equipment.
B. Open the buffer tank valve to allow flow to downstream equipment. Start
equipment and check for leaks.
C. Secure tubing, hoses and wires to assure the installation is neat and not
susceptible to damage. Place shroud back onto processor. Replace the storage
tank cover.
D. Complete the post-installation checklist and the service log and leave them
with the operator/owner.
