Material Heater
WARNING! Before performing any maintenance, make sure the Main Power
Switch is OFF and incoming power is locked OFF. NEVER access the inside of
the Control Panel with the Proportioner power supply ON. The Heaters are
components that reach high temperatures; you must wait until they have cooled
before handling and bleed all material pressure to zero.
Thermocouple Replacement
Note!
The Thermocouple is assembled into the
Connector Body with a Ferrule and Nut. Once
inserted into the Body and the Nut is tightened,
the Ferrule locks to the Thermocouple and does
not allow it to be relocated or moved. The
location of the Thermocouple is very important
and must be done correctly before tightening the
Nut.
1. Unscrew the Nut that holds the defective
Thermocouple and remove from the Body.
Disconnect Thermocouple wiring located under
the Top Cover of the Heater. Remove Body and
discard.
2. Install Connector Body into Heater using an
open-end wrench and tighten to prevent
leakage. Teflon Tape or appropriate Thread
Sealant should be used.
3. Slide the Nut and the Ferrule over the
Thermocouple and insert this assembly into the
Connector Body until it comes into
positive
physical contact with the Heating Rod. Make
sure the Spring does not prevent the
Thermocouple from making contact with the
Heating Rod.
4. Slowly tighten the Nut using an open-end
wrench, ensuring the Thermocouple maintains
positive physical contact with the Heating Rod.
5. Reinstall the Thermocouple wires.
