I'm pretty sure you'll be okay provided the cycles are adequately spaced, and the voltage is correct; these units are very durable. However, since the entire thing is sealed in a steel can, I wouldn't expect any overtemps to be apparent from outside until well after the event.
Basic temp safeties on industrial compressors are:

You could get the discharge temp by attaching a sensor, with plenty of thermal insulation round it, to the copper discharge pipe from the can. However, I doubt this would give you any useful information.
A couple of nice new low-stage Mycoms going for it:
