Installation of Floats
Standard three phase simplex panels are designed
to operate with three fl oats. These fl oats operate the
pump stop, pump start, and high level alarm functions.
NOTE: Options ordered may affect the number
of fl oats and their functions. Please reference
the schematic provided with the control panel for
proper installation.
CAUTION: If control switch cables are not wired and
mounted in the correct order, the pump system will not
function properly.
WARNING: Turn off all power before installing fl oats in
pump chamber. Failure to do so could result in serious
or fatal electrical shock.
1. Use fl oat label kit to identify and label cables on
both the fl oat and stripped ends (stop, start, alarm,
etc.). See schematic for fl oat options.
2. Determine your normal operating level, as illustrated
in Figure 1.
3. Mount fl oat switches at appropriate levels as il-
lustrated in Figures 2-4. Be sure that fl oats have
free range of motion without touching each other
or other equipment in the basin.
If using the mounting clamp; follow steps 4-6.
4. Place the cord into the clamp as shown in Figure
2.
5. Locate the clamp at the desired activation level and
secure the clamp to the discharge pipe as shown
in Figure 2.
NOTE: Do not install cord under hose clamp.
6. Tighten the hose clamp using a screwdriver. Over
tightening may result in damage to the plastic
clamp. Make sure the fl oat cable is not allowed to
touch the excess hose clamp band during operation.
NOTE: All hose clamp components are made
of 18-8 stainless steel material. See your SJE-
Rhombus
® supplier for replacements.
