Label each float and cord end with the provided STOP, LEAD, LAG, and ALARM stickers.
Mount the control panel ensuring proper distance and connections for correct pump function
Ensure floats have free range of motion and are not obstructed.
Securely tighten the pipe clamp, ensuring it does not interfere with float operation.

Wiring the Control Panel :

Determine conduit entrance locations on the control panel as per the provided schematic.
Check local codes and panel schematic for required power circuits.
Ensure pump power voltage and phase match the pump motor specifications.

Frequently Asked Questions (FAQ):

Can I install the control panel myself?
The control panel must be installed and serviced by a licensed electrician in compliance with relevant electrical codes to ensure safety and proper operation.

Installing the Float Switches

The Model 123 Single Phase Duplex control panel operates with fl oat switches. They activate pump STOP, LEAD pump START, LAG pump START and high-level ALARM functions.

Ensure all power is turned OFF before installing fl oats 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. $SJE-RHOMBUS-123-Single-Phase-Duplex-Capacitor-Control-Panel- $3$$
CAUTION!
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 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.

Floats require free range of motion. They must not touch each other or any equipment in the pump chamber. $SJE-RHOMBUS-123-Single-Phase-Duplex-Capacitor- Control-Panel- $5$$ $SJE- RHOMBUS-123-Single-Phase-Duplex-Capacitor-Control-Panel- $6$$

Wiring the Control Panel

Determine conduit entrance locations on control panel as shown. Check local codes and schematic on the inside cover of 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 on inside cover of the control panel for details.

Operation

SJE Rhombus Model 123 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. $SJE-RHOMBUS-123 -Single-Phase-Duplex-Capacitor-Control-Panel- $7$$ $SJE-RHOMBUS-123-Single-Phase-Duplex-Capacitor-Control-Panel- $8$$

Typical Layout (May vary with options ordered).

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.
