Common Questions:

What equipment is the Robertshaw 5300-612 compatible with?
This model is primarily used in commercial electric ovens, holding cabinets, and industrial process heaters requiring a 60-250°F range. It is a frequent direct replacement for many 5300 series parts.

How do I handle the long capillary tube during installation?
The 60" capillary allows for remote mounting; ensure the bulb is properly clipped in the sensing area, and avoid sharp kinks or bends in the tubing which could compromise the NAK-filled diastat fluid.

Can I calibrate this thermostat in the field?
Yes, the 5300-612 allows for calibration adjustments via the center stem screw, enabling technicians to fine-tune the temperature accuracy if the burner or element cycles out of spec.
