Install Instructions

Installation Instructions
Most three phase duplex panels are designed to operate with three
or four float systems. The three float system is standard, performing
the common pump stop, lead pump start, and lag pump start/high
level alarm functions. The four float system utilizes separate floats
for each function.
NOTE: Options ordered may affect the number of floats 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 floats in pump cham-
ber. Failure to do so could result in serious or fatal electrical shock.
1. Use float label kit to identify and label cables on both float and
stripped ends (stop, lead, lag, alarm, etc.). See schematic for
float options.
2. Determine your normal operating level, as illustrated in Figures
1 & 2.
3. Mount float switches at appropriate levels as illustrated in Fig-
ures 3-5. Be sure that floats 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 float 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.
