6. For KP 1W and KP 1 manual reset models, the contact 1-2 opens on pressure rise. These models are listed as refrigeration controller 61B5 according to UL regulations.

7. Set the desired pressure settings using the adjustment mechanism provided on the pressure switch. Refer to the manual for specific instructions on adjusting the pressure settings.
