Filling the System
In normal operation of the system, flipping one of the switches
to "Fill" will start the system filling the associated ballast. The
ballast gauge will have an arrow showing the flow direction.
The pump will automatically turn off when the appropriate
amount of time to fill the system has been reached. The light
on the switch will still be luminated as it is in the "Fill" position,
but the pump will not be running. The switch should be turned
back to the "off" position when the pump stops running.
Emptying the System
In normal operation of the system, flipping one of the switches
to "Empty" will start the system emptying the associated ballast.
The ballast gauge will have an arrow showing the flow direction.
The pump will automatically turn off when the appropriate
amount of time to empty the system has been reached. The
light on the switch will still be luminated as it is in the "Empty"
position, but the pump will not be running. The ballast gauge on
the Supra Vision system will show empty. The switch should be
turned back to the "off" position when the pump stops running.

Ballast Pump Impellers
The pumps that fill and drain the ballast system use an impeller.
Your Supra ballast impeller uses the latest polymer technology in
an effort to have the longest service life possible. The impellers
are a wear item and different use patterns, water types, debris,
etc. can greatly affect the service length of the impeller. As the
impellers wear, the amount of water that is pumped into and out
of the ballast system is reduced. The Vision system does have
provision for adjusting fill and empty times to accommodate
decreased efficiency due to impeller wear or changing to
difference sized bags (See Vision Dash "System Settings" For more
info). Running the pumps without water will greatly accelerate
the wear and prolonged running of the pumps without water
will damage the impeller to the point that they will require
immediate replacement.
Note: Impellers are a wear item and not covered by warranty.
Ballast System Utilities- It is not recommended to change any
of the ballast configuration that are found under the" Utilities"
menu on the Vision Dash unless specifically directed to do so
by your Authorized Supra dealer. Changing these values may
negatively affect the ballast system or may make the system fail
to work all together.
