Installation Instructions
Most three phase duplex panels are designed to operate with three
or four fl oat systems. The three fl oat system is standard, perform-
ing the common pump stop, lead pump start, and lag pump start/
high level alarm functions. The four fl oat system utilizes separate
fl oats for each function.
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.
Installation of Floats
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 cham-
ber. 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 fl oat and
stripped ends (stop, lead, lag, alarm, etc.). See schematic for
fl oat options.
2. Determine your normal operating level, as illustrated in Figures
1 & 2.
3. Mount fl oat switches at appropriate levels as illustrated in Fig-
ures 3-5. 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 5.
5. Locate the clamp at the desired activation level and secure the
clamp to the discharge pipe as shown in Figure 5.
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.
