SUBJECT: CHANGE IN FIVE-PORT PUMPED CHEMICAL INLET ON 35-135 POUND RIGID WASHER-EXTRACTORS

Dear Gentlemen:

The attached document explains a recent modification we have made to the chemical inlet device on certain models of our washer-extractors.

This change has bee made in another attempt to minimize the vexing problem of "chemical dribble" that continues to damage machines and their contents. The phenomenon is thoroughly explained in the attachment. Please note that we cannot control this phenomenon and accept no responsibility for the consequences of dribbling/leaking chemical inject tubes.

Although we believe that our new scheme will probable reduce the dribbling effect about as much as it is possible to achieve without flushing, there is no question that slushing the just-used chemical injections tube with water after each injection is the only sure way to prevent machine/linen damage. (Such a design change would, of curse, be the responsibility of the pump and/or chemical vendor.)

Please give this bulletin widespread publicity within your organization.

Yours Very Truly,

PELLERIN MILNOR CORPORATION
