Maintenance Considerations Modular Ovens

The following practices must be observed in order to operate, maintain and prevent
compromise of the Maxum II Modular Oven heater system.
● The installaion of the heater elements and RTDs should be inspected to verify that they are
fully inserted into the tubes as shown in the previous section. Heater wiring should be
inspected for any damage and proper connection to the PECM-DC.
● Application modules should be properly installed with their cover plates, and the face plate
of the modular oven should be installed and secured with the provided thumb screws.
● Because of the relatively low operating temperature, low power, and stable temperature
applications, the expected life of the heater elements is expected to be many years.
However, if a heater element burns out, replacement is possible. The new heater must be
installed using proper techniques to ensure that the heater is re-installed correctly. This
process should be supervised by persons knowledgeable about local electrical and fire
safety practices.
