Antes de realizar el mantenimiento se observó que el sistema N° 2 estaba alarmado y bloqueado por esta alarma desde el 5 de Noviembre, esta alrma era de BAJO SOBRECALENTAMIENTO DE DESCARGA, se revisó en le mantenimiento y se observó que el sensor de temperatura de succión estaba descalibrado, se cambió y se deja operativo el sistema N° 2.

Se observa que los serpentines condensadores se siguen deteriorando paulatinamente a pesar de eso los parámetros de funcionamiento aun están dentro de rangos normales., tener en cuenta que el equipo viene operando 10 años continuamente las 24 horas del día y sin interrupción
