CAUTION
All Mold-Masters heated components are manufactured to standards that
ensure safe and reliable operation provided that the following precautions
are met:
• To maximize heater element and component life, the temperature must
be controlled and maintained within safe operating limits. Mold-Masters
strongly recommends individual control of each heated component,
including heater plates, with a reliable temperature controller that
includes soft-start protection.
• Always operate the system using correctly installed “J” type
thermocouples connected to a reliable temperature controller with soft-
start protection.
• Avoid running the system for long periods on manual control.
• Use caution when applying power in manual mode. Use minimum heat
required for the process to avoid overheating and possible damage to
components.
• Always replace pinched or damaged thermocouples.
• When grouping heated components together and controlling more than
one load from a single thermocouple, make sure that the components
are of similar material, wattage, size and are exposed to the same
thermal conditions.
• When replacing heater plates or other heated components always
replace with Mold-Masters components of the same type and install as
originally specied on Mold-Masters General Assembly drawings.
