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.
If the fl oats are not properly mounted and connected in the correct
order, the pumps will not function properly.
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.
