Installing the Float Switches

The Fusion™ Single Phase Simplex control panel operates with 3 float switches to activate pump STOP, 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.

Step 2: Label each float and cord end with the provided pairs of STOP, START and ALARM stickers.

⚠️ CAUTION! If the floats are not properly mounted and connected in the correct order, the pumps will not function properly.

Floats require free range of motion. They must not touch each other or any equipment in the pump chamber.

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 a CSI Controls UL Type 4X junction box.

Pipe Clamp Mounting Simplex

Diagram Description: This section illustrates the pipe clamp mounting method for float switches in a pump chamber. Three float switches are shown: Alarm (at the highest level), Start (at the middle level), and Stop (at the lowest level). The 'Operating range' is the space between the Start and Stop floats. Proper positioning ensures the pump activates when the liquid reaches the Start float and deactivates when it drops below the Stop float. The Alarm float triggers an alert if the liquid level rises too high.

Hose Clamp Detail

Diagram Description: This detail shows how to properly secure a pipe with a hose clamp. The clamp should be tightened securely. The hose clamp is made of 18-8 stainless steel. A recommended distance for clamp placement or size is indicated as 3.5 inches (9cm). Crucially, ensure the hose clamp band does not interfere with the movement of any float switches. Also, do not route any cords underneath the hose clamp.

Wiring the Control Panel

Step 1: Determine conduit entrance locations on the control panel as shown. Check local codes and the 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.

Step 2: Connect the following wires to the proper terminal positions: incoming power, pump, float switches. Refer to the schematic inside the control panel for detailed wiring diagrams.

Diagram Description: A typical internal layout of the control panel is shown, illustrating the general arrangement of components and terminal blocks for wiring connections.

⚠️ CAUTION! You must use conduit sealant to prevent moisture or gases from entering the panel. Type 4X conduit must be used to maintain the Type 4X rating of the control panel.

Step 3: Verify correct operation of the control panel after installation is complete.

Operation

The Fusion™ Single Phase Simplex control panel operates using float switches. When all floats are in the open (OFF) position, the panel is inactive. As the liquid level rises and closes the STOP float, the panel remains inactive. The panel becomes active and the pump will turn ON only when the START float also closes (provided the Hand-Off-Auto switch is in AUTO mode and power is ON). The pump will remain ON until both the STOP and START floats return to their open (OFF) positions.

If the liquid level rises to reach the ALARM float, the alarm will be activated.

Alarm System (Beacon Light and Horn)

When an alarm condition occurs, the flashing red light and horn will be activated.

The TEST/SILENCE switch has two functions: If toggled when an alarm is present, it will silence the horn until the alarm condition is reset. If toggled when no alarm is present, it will activate the alarm (light and horn) until the toggle is released.

Hand-Off-Auto (HOA) Switch

The HOA 3-way switch controls pump functions:

HAND mode: The pump will turn ON.
OFF: Turns the pump OFF.
AUTO mode: Commands from the float switches turn the pump ON and OFF.

Circuit Breakers

Circuit breakers provide pump and control/alarm disconnect and branch circuit protection.

Motor Contactor

The motor contactor controls the pump by switching electrical lines.
