Page 9: Chapter 3 Adjustments After Installation
CHAPTER ADJUSTMENTS AFTER INSTALLATION The factory-set setpoint or adjustable setpoint range is marked on the nameplate of the switch. This section describes the adjustments needed after an Adjustable Pressure Switch has been properly installed. Models 125P, and 225P are not adjustable. SETPOINT ADJUSTMENT WARNING Do not remove switch while under pressure. - Page 10 6. If you want to check the decreasing setpoint, slowly decrease the pressure or vacuum after the switch has actuated and note the value at which the audible snap or an ohmmeter indicates deactuation. Deadband may be calculated if desired by subtracting the decreasing setpoint reading from the increasing setpoint reading.
