- Technical Support: +1-800-746-6287
Product Usage Instructions
Installing the Float Switches:
- Ensure all power is turned OFF before installing floats in tank to prevent shock.
- Label each float and cord end with provided STOP, LEAD, LAG, and ALARM stickers.
Mounting the Control Panel:
- NOTE: If distance exceeds cord length, use a liquid-tight junction box. For outdoor installations, use an SJE Rhombus UL Type 4X box.
- CAUTION: Properly mount and connect floats in the correct order to ensure pumps function correctly.
Pipe Clamp Mounting for 3 Float Operation:
- Floats must have free range of motion without touching each other or equipment in pump chamber.
- Tighten the clamp securely without interfering with float operation.
Wiring the Control Panel:
- Determine conduit entrance locations on the control panel.
- Check local codes and panel schematic for required power circuits.
FAQ:
-
Q: What should I do if the pumps are not functioning properly?
A: Ensure floats are properly mounted and connected in the correct order. Check wiring connections and power supply. -
Q: Can the control panel be used for both indoor and outdoor applications?
A: Yes, the UL Type 4X enclosures allow for safe use indoors or outdoors

Installing the Float Switches
The Model 122 Single Phase Duplex control panel operates with 3 or 4 float switches to activate pump STOP, LEAD pump START, LAG pump START and high-level ALARM functions.
- Ensure all power is turned OFF before installing floats in tank. Failure to do so could result in serious or fatal shock.
- Label each float and cord end with the provided pairs of STOP, LEAD, LAG, and ALARM stickers.
- If the floats are not properly mounted and connected in the correct order, the pumps will not function properly.
Mounting the Control Panel
NOTE If the distance to the control panel exceeds the length of the float
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.
Floats require free range of motion.
They must not touch each other or any equipment in the pump chamber.
Wiring the Control Panel
-
Determine conduit entrance locations on control panel as shown. Check local codes and schematic inside the panel for the number of power circuits required.
CAUTION! Be sure the pump power voltage and phase are the same as the pump motor being installed. -
Connect the following wires to the proper terminal positions:
- incoming power
- pump 1
- pump 2
- float switches
See schematic inside control panel for details.
CAUTION! You must use conduit sealant to prevent moisture or gases from entering the panel.
Type 4X conduit must be used to maintain a Type 4X rating of the control panel.
-
Verify correct operation of control panel after installation is complete.
Operation
SJE Rhombus Model 122 Single Phase Duplex control panel operates with float switches. When all floats are in the open or OFF position, the panel is inactive. As the liquid level rises and closes the STOP float, the panel remains inactive until the LEAD float closes. At this point the LEAD pump will turn ON (if the Hand-OFF-Auto switch is in the AUTO mode and the power is ON). The pump will remain ON until both the STOP and LEAD floats return to their OFF positions. If the liquid level rises beyond both the STOP and LEAD floats to reach the LAG float, the lag pump will turn ON (if the Hand-OFF-Auto switch is in the AUTO mode and the power is ON). Both pumps will remain ON until the STOP, LEAD, and LAG floats return to their OFF positions. If the liquid level rises to reach the ALARM float, the alarm will be activated.
