3 or 4 fl oat switches to activate pump STOP, LEAD pump START,
LAG pump START and high-level ALARM functions.

CAUTION!
NOTE
Ensure all power is turned OFF
before installing fl oats in tank.
Failure to do so could result in
serious or fatal shock.
Label each fl oat and cord end
with the provided pairs of
STOP, LEAD, LAG, and ALARM
stickers.
If the distance to the control panel exceeds the length of
the fl oat switch cords or the pump power cord, splicing
in a liquid-tight junction box will be required. For outdoor
or wet installation, we recommend an SJE Rhombus UL
Type 4X junction box.
