Myron L - AQUASWITCH machinery

Warranty
All Myron L AQUASWITCH I & II controllers and sensors have a two-year warranty.  If any AQUASWITCH or sensor fails to function normally, return it to the factory prepaid.  If, in the opinion of the factory, failure was due to materials, or workmanship, repair or replacement will be made without charge.  A reasonable service charge will be made for diagnosis or repairs due to normal wear, abuse or tampering.  Warranty is limited to the repair or replacement of the Myron L AQUASWITCH or sensor only.  Myron L Company assumes no other responsibility or liability.

Sensors

AQUASWITCH II models require either a CS-10 or CS51 series sensor.  These reliable sensors feature two integral thermistors to ensure accurate and rapid automatic temperature compensation.  The sturdy polypropylene standard bushing is modular for easy, inexpensive replacement.  A PVDF or 316 stainless steel bushing can also be ordered.  The metal portion is available in either 316 stainless steel or titanium.

Two models to choose from:

The standard AQUASWITCH I does not monitor water quality itself, but may be used with any reliable resistivity or conductivity monitor/ controller such as the Myron L 750 Series II.  The AQUASWITCH II is an integrated unit with a built in 750 Series II Resistivity or Conductivity Monitor/controller.  They are available in several ranges.

The AQUASWITCH features advanced circuitry, including three solid state (not mechanical) relays to reliably operate the solenoid valves.  Three or four solenoid valves suitable for ultrapure water (not supplied) are needed to make a complete AQUASWITCH system.

The purge cycle is controlled by a timer which is easily adjustable for periods from 1-10 minutes.  This feature allows the system to be tailored to the requirements of each application, and ensures banks are not switched or shut down prematurely.  A "manual change over" button can be depressed to switch banks at any time.

What it Does:

The AQUASWITCH is a special purpose dedicated computer which automatically "changes out" an exhausted DI bank for a fresh, stand-by bank.  LEDs continually give the condition of both banks. An alarm output is activated as each bank is depleted.
 
How it Works:

When the monitor/controller senses poor quality water merely because the DI system has been shut down temporarily, the AQUASWITCH purges the "on-stream" bank until water quality recovers.  If the DI bed is exhausted, however, water quality will not improve sufficiently after purging.  The AQUASWITCH will then automatically take the exhausted bed out of service and switch over to the stand-by bank.  The fresh bank is purged until the desired quality level is reached; it then goes into service.
