Auto Tune Oil Heater Controller
The ThermoJet Oil Purifier must be running and operating normally in order to perform this
maintenance task.
To access the heater controller, unthread the enclosure cover it from the base.
Care should be taken when removing and reinstalling
the controller enclosure so prevent damage to any
flame proof joint, such as between the enclosure and
the treaded cover. Flameproof joints are not to be
repaired in the field. If the flame path is damaged the
enclosure is to be removed from service and replaced
with a new properly working enclosure.
Before performing this maintenance task ensure that
the area is clear of all hazardous or explosive gases
or materials, and that a HOT WORK PERMIT or other
authorization to work has been issued and posted
according to all facility standards and procedures.
Where required proper monitoring and alert systems
and process must be in place and in operation during
the performance of work.
Observe all local and state laws and restrictions.
Failure to do so may result in explosion and loss of
property, serious injury or even loss of life.
WARNING
Unthread the enclosure
cover to access the
temperature controller
