Connecting Dual float Switch (SW-1WOP) To Control Box

1.Remove the float switch input connector housing, then route the float switch wires through the cable gland on the control box. Attach the wires of the float switch to the terminal block as indicated by Table 5 and Figure 10.

2.Tighten the connector housing to ensure a tight fit between the cord and the connector body. This will prevent the cable from pulling out of the terminal block and also prevent moisture from entering the control box.

3.Determine the tether length of the float switch wires then secure float switch wires to pump discharge hose. See Figure 8 or Figure 9 and Table 3 to determine the pumping range.

Connecting AC Power to the CB3 Control Box

1.The AC input power cord (not included) should have three wires. Each wire is color coded. The colors are

WHITE, BLACK and GREEN.

2.Remove the AC input connector housing from the control box, then route the power cord through the cable gland on the control box.

3.Connect the AC input power cord to the contactor located inside the control box as shown in Figure 10, and Table 6.

4.Connect the other end of the AC power cord to the voltage source. Remember to provide a means of disconnecting the power from the control box (circuit breaker or quick disconnect switch). Also make sure to provide a good earth ground to the control box

NOTICE

It is recommended that the power being supplied to the control box ALWAYS be connected to a circuit breaker or a quick disconnect switch. This safety feature allows for quick removal of power from the control box in the event of an emergency.

Connecting AC Power to the Pump Motor

1.AC power is routed to the pump motor via a contactor. The coil of the contactor is energized or de-energized by the opening and closing of the float switch contacts.

2.The power cord (included with pump) should have three wires. Each wire is color coded.The colors are WHITE,

BLACK and GREEN.

3.Remove the pump AC input connector housing from the control box, then route the power cord through the cable gland on the control box.

4.Connect pump power cord to the contactor as shown in Figure 10, and Table 7.
