PUMP INFORMATION MODEL:  3Z182C, 4 5/8 & 2 1/2“ Bore x 3" Stroke, 4 Cylinder, Cast-Iron Flywheel, 19.0 O.D. Counterclockwise Rotation. PRESSURE SWITCH ADJUSTMENT WORKING  RANGE  (Large  Spring)  -  Switches  are  set  at  the  factory  to operate at the pressure indicated on the nameplate.  To raise operating pressure, turn the range spring nut down, which compresses the range spring.  Loosen the range spring nut to lower the operating pressure. DIFFERENTIAL  (Small  Spring)  Pounds  pressure  between  "Open",  and "Close" is referred to as the differential.  To increase the differential, turn down  the  differential  spring.    By  loosening  this  nut,  differential  will  be narrowed.  (Differential adjustments affect cut-out point only). Wiring diagram for pressure switch is included with the switch.  Wiring diagram for the motor is found either on the motor nameplate, or on the terminal board of the motor. When making electrical connections, unit should be grounded by means of  a  grounding  conductor,  or  by  connection  to  a  grounded,  metallic raceway electrical system. - 1 -
