THOMPSON STRAINER SCREEN FILTER - OPERATION MANUAL
The Thompson Strainer Screen Filter is a highly efficient, stainless steel strainer which features a large conical screen offering
substantially more screen surface area versus traditional basket or "Y" strainers. As water enters the bottom of the strainer housing
and flows upward, heavier debris and particulate is accelerated downward, away from the conical screen, into the large debris
reservoir at the base of the strainer. Particulate can be flushed from the reservoir via the flush port either manually or automatically
with optional flush package. All models operate with less than 1-psi pressure loss at maximum flow when clean.
Serial #
The Serial # is located on the top of the outlet flange or pipe.

All strainers with a side inlet and a bottom foot ring must be placed on a firm supporting surface.
DO NOT suspend the strainer by the inlet and outlet connections. All strainers with vertical inlet piping must be plumbed
into properly supported piping.
4.
Units with damaged or missing parts should NEVER be operated.
5.
Back-flow prevention devices should be installed upstream of the inlet and downstream of the outlet of the strainer to prevent
back flow or vacuum effects that can be damaging to the strainer.
6.
Pressure relief valves of a sufficient size and volume should be installed upstream of the inlet and downstream of the outlet
of the strainer. They should be set so the system never exceeds the maximum rated pressure. Failure to install relief valves
could lead to personal injury or product damage.
