6.0 ARC SCHEMATIC
IMPORTANT FOR OPERATION:
Piping between the concentrate vessel and concentrate controller is not furnished by the Concentrate Control system
manufacturer. The concentrate piping to the controller must meet certain criteria to prevent loss of concentrate into the
water supply piping. This piping (dotted lines on the schematic below) is to be included by the design engineer for the
type system wanted - manual, electric, pneumatic, fail-safe, etc. Viking does not accept responsibility for concentrate
piping to the controller or water piping to the concentrate vessel.
NOTE: (Per schematic below) Manual System - Valve No.’s 1 and 2 must be opened manually.
Automatic System - Valve No. 8 must be opened with an alarm signal
(if necessary, use manual override).
TYPICAL SCHEMATIC DIAGRAMS:
Consult the system design for actual piping requirements. Before filling system, consult manufactures filling
procedure. Improper filling can result in damage to the concentrate bladder.
