      If the pump is persistently becoming air-locked on your Boss Industrial Equipment, the wrong/no flow restrictor is installed in the float valve (MX, Digifiller and midi units only). Check float valve flow restrictor selection (MX, Digifiller and midi units only).

      If P2 FAIL is displayed but the unit is a single pump model on your Boss Industrial Equipment, the PUMPS NUMBER option is incorrectly set to 2. Set PUMPS NUMBER to 1.
