Installation

4.

Install the two screws through the pinch plate and into the pump/valve module. 
Secure the pinch plate by turning the screws in small increments moving from one 
screw to the other so that the plate is drawn down evenly. Tighten until the plate is 
seated against the pump/valve module.
