direct power operation
The CX400/PX400 submersible pumps can be configured to operate by direct power (Figure 4) or connected to a control
box (Figure 10) utilizing float switches. When the pump is connected directly to a 1Ø, 115 VAC, 60 Hz power source, the
pump will operate soon as power is applied. It is suggested that a quick disconnect switch be installed as a means of
turning the power on and off.
When operating the pump using direct power (no control box), the pump must be monitored at all times. Failure to monitor
the pump during operation could lead to severe pump damage should the pump encounter problems such as a stuck
impeller or not fully immersed in water.
