1.Push the PUMP START button to start the pump.

2.When the unit has built at least five (5) psi (34.5 kPa) of pressure, wait two (2) minutes, then select a set point of 100°F (38ºC) and switch the unit into AUTO mode.

As the oil warms up, viscosity decreases and pressure falls.

3.Four to six inches (4” to 6” / 10 cm to 15 cm) of fluid should be visible in the sight glass.

4-2 Controller Description & Operation

The M2B+ controller is an easy-to-operate microprocessor-based PID control device. When the process reaches the set point, the PID control cycles the cooling valve and/or immersion heater to maintain the proper leaving temperature.

The controller has been fully factory tested. Set the desired process temperature set point and the controller does the rest.

Built-in range of operation on the controller is -4°F to 120°F (-20ºC to 49ºC).

Refer to the M2B+ Owner’s Manual supplied with your unit for specific operation instructions.
