• The FLUENT heater should not be powered unless fluid

flow is present.

• The integrated Type K thermocouple is mounted on the

heating element and should only be used as a high limit
sensor with a latching limit control.

• The maximum limit temperature setting is 350°C. A lower

setting may be applicable and provide improved product
protection.

• Fluid temperature sensing must be accomplished by a

downstream sensor.
