how to adjust the regulator on a deep well jet pump

we just purchased a new jet pump and it says the regulator has been factory set for shallow wells and you must manually set it for deep well,however, it does not say how to reset it and our previous pump did not have a regulator on it

You did not mention the model number of the jet pump that you have. Based on the current models, I assume that you likely have a Craftsman model 390.2522 or similar pump. If you have this type of pump, the procedure for adjusting the pressure regulator is on page 11 of the manual. Here is a link for the manual for Craftsman pump model 390.2522:

If you have a different type of pump or need more help, resubmit your question with additional details and the full model number of your pump.
