Air Purge
Upon initial start-up and mold/process change-out, you’ll need to
purge all air and water from the system. The
2016-C unit has
appropriate valving to ensure complete purging; procedures are
covered in Section 4 on Page 25.
!
WARNING
Failure to purge the system of air before heating
may result in serious injury or critical system and
equipment damage.
Make sure you properly purge the system of air
before starting the heater cycle.
Pressure Switch
A pressure switch is built into each unit to guard against heater
damage. This feature prevents the heater elements from being
energized unless the pump is running and fluid is in the system.
After a preset time, the pump shuts down if the fluid pressure is not
re-established. The pressure switch is preset at the factory; do not
tamper with it.
Safety Thermostat
The safety thermostat is a J-Thermocouple sensing, adjustable,
fail-safe device located in the heater tank. This is to guard against
the unlikely event of “runaway” heating. If overheating does occur,
the safety thermostat shuts down the heater outputs and sounds an
audible alarm. A red pilot light on the status board also illuminates.
The unit continues to pump fluid through the system to prevent
heater damage. Auxiliary factory installed alarms such as beacons
and klaxons are available as options.
All controller functions are locked out until the main supply power
is disconnected. Resetting the alarm condition is initiated by
depressing the red pump stop button. The reset button is located
inside the electrical enclosure, mounted on the left wall of the
enclosure. It is imperative that a qualified maintenance technician
determine and correct the cause of the fault before resuming
operation.
