Figure 3: Control Box Front Cover
Figure 4: Start/Stop Jumper
Remove the 5 screws on the front cover of the control box with a T20 Torx driver. The Start/Stop jumper and electrical connections are
located beneath the cover. Before attaching power, remove the Start/Stop jumper located inside the pump control module (remove the
entire green plug with the grey jumper). This will prevent the pump from starting when powered.
Complete the high voltage wiring to the pump. Locate the power supply plug and conduit adapter in the box supplied with the pump.
Connect wiring from pump disconnect to the pump terminal block as shown in Figure 5. Pump terminals are labeled L, N, and ground
(symbol). Connect L to L1 and N to L2. Wiring must meet all applicable code requirements, including requirements for wire protection, such
as conduit. Wire and breaker/fuse size must be determined based upon pump nameplate ratings.
