Use the illustration and instructions to understand
the system activity when you set it to an off-board
concentrate source.
Note: For instructional purposes, this illustration
only focuses on the specific activity in the
system that best conveys the topic.
1 When set to off-board supply mode, a valve is
used to change the concentrate source from the
on-board supply tank to the overboard pick-up
system. When sourcing concentrate from an
off-board source, the system cannot measure
the supply level—the concentrate supply must
be managed by the operator.
Note: Do not operate the equipment without
providing concentrate or water to pump
through the system.
