SOR 1710 Compact Level Switch - Manual (Page 2)

2/8 Form 916 (03.14) ©SOR Inc.
Physical Installation
 The 1710 must be mounted so that the centerline is within 3º of horizontal. The
conduit connection centerline must be within 3° of vertical and the nameplate at 12
o’clock. Switch actuation cannot be reversed by rotating the unit 180°.
 Pipe support hangers or stands should be used where necessary.
 All isolation valves must be fully open during service, as restricted valves may
cause erroneous level switching.
 Remember external chamber piping should be short, straight and unrestricted.
 Pipe must be of a diameter equal to or greater than the process connection
diameter.
 Valves and other equipment between the chamber and process must be of the same
diameter or larger than the process connection diameter to allow adequate liquid
flow into the chamber.
 Installation shall be carried out by suitably-trained personnel in accordance with the
applicable code of practice e.g. EN 60079-14.
Not following these installation instructions, including pipe and valve
diameter and pipe lengths can affect operation of the switch, including
differential.
