Main Controller Calibration:
The main temperature controller should be checked for temperature indicating accuracy, and for the proper
activation of limit or alarm outputs (when provided). Please reference the controller user manual for more
information.
Inspection Period: 1 Year
Limit Controller Alarm Circuitry:
The Temperature Limit Controller should be checked for indicating accuracy and for proper activation of limit
or alarm outputs. A quick test is as follows:
1. Set the OTP control at a temperature lower than the Operating temperature.
2. Run the unit in the normal operation mode. If the OTP circuit is performing properly, the unit should shut
down when the chamber temperature exceeds the OTP setpoint temperature. If the unit fails to shutdown
reduce the oven temperature to ambient and diagnose the OTP circuit.
3. Press the OTP reset switch to and restore the unit to operation. The OTP controller should be set to
11°C higher than the units normal operating temperature.
Please reference the controller user manual for more information.

Cleaning:
Important! NEVER use a cleaning solution that contains chloride or flouride ions. These ions are
aggressive and highly corrosive, and will attack stainless steel.
Thoroughly wash all surfaces with an appropriate cleaning solution.
Thoroughly rinse all surfaces.
Do not permit the HEPA filters to come in contact with any cleaning solution when cleaning with the duct
walls removed. Make sure the filters are adequately covered. (when employed)
When cleaning the conditioning plenum, proper precaution should be taken not to spray beyond the
