Dump Solenoid Connection
For direct feed applications, the dump solenoid is wired to the 120 Volt motor cord contacts L1 and L2. When the motor is
running the dump solenoid valve is energized and closes. When the unit shuts down, the dump solenoid valve opens to
drain.
Dry Contact Connections
The dry contact terminal strip is located on the bottom right of the circuit board (see Figure 18). Do not apply any voltage
to these terminals. Use dry contacts only.
