Over Temperature Protection:
The PDQ Ovens have a maximum temperature setting of 450°F or 243°C.
In addition an over temperature shut off device (Limit Switch) is supplied
that will turn the emitters off if the temperature exceeds 500°F or 260°C.
A reset button is located on the back of the oven above the main power
supply entry point. Unscrew the cap and push the button firmly if an over
temperature situation occurs.
Over Temperature Protection Device Check:
1.
Disconnect electrical power and ensure the oven is cool to the touch.
2.
Remove the devices' temperature probe (short copper bulb and capillary
tube not the long chrome probe) from the mount on the inside of oven.
3.
Insert probe into a handheld dry-well calibrator (ex. Hart Scientific
9100S) and heat the probe.
4.
The device should trip between 500°F and 525°F.
5.
Allow the probe to cool to room temperature and reinstall in mount.
