Ultima Switch
The Ultima Switch is a highly reliable solid state switch which uses
no mechanical parts or toxic mercury to sense water level and
automatically controls a 12V DC or 24V DC bilge pump. The switch
activates the pump when the water level reaches 2" or more and
turns off the pump when the water level reaches below ¾". The
Ultima Switch automatically adjusts between 12V DC bilge pump or
a 24V DC pump without any adjustments necessary.
Caution!
1. Connect an inline fuse of the appropriate amperage (specified on
the pump).
2. The Ultima Switch is designed for 12V DC and 24 V DC
operation only. Do not use any other voltages, do not use AC or
AC-DC converted power sources.
3. Failure to use the appropriate fuse and connecting wires
according to the instructions provided will void any SPX FLOW
Johnson Pump Warranty and may cause serious damage or
personal injury.
Installation
Location:
1. Mount the Ultima Switch in a vertical position (Mount holes
towards the bottom of vessel) and close to the pump such that
the water level is equal on both pump and the Ultima Switch.
2. Do not mount the Ultima Switch directly to the hull of the boat.
Use a mounting block of at least ¾" thick marine plywood epoxied
to the hull of the boat to fasten the Ultima Switch.
