Powering the Jacket Water Heater

If you have a non-jacketed vessel, skip this section. After sterilization, you should have
installed the vessel on the jacket water heater and connected the heater to the Power
Controller (see Section 6.4). Never set the temperature control loop to the desired
working temperature (refer to Section 7.4.1) until all water connections have been made,
the jacket is filled with water, the vessel is filled with media, and the RTD has been
installed in the thermowell and connected to the Power Controller.
Never plug the jacket water heater into the controller before the vessel is filled. When the
heater is connected properly and the PCU is turned on, the jacket water stirrer should spin
freely.
WARNING!
When the jacket water heater is plugged in, do not touch the top surface.
It is very hot.
