INTRODUCTION

 

An automatic, self-cleaning strainer requires a control 
system to provide flexibility and optimize performance of 
the straining operation. A number of standard options 
are available or specify a custom designed control 
system. 

 

This manual will define the installation requirement, 
operation, and maintenance of the Eaton control system.
