Easy to install, economical smart protection 1596 Prevents rapid cycling under harmful high or low pressure conditions. A Detection and Protection System The ACX-10 A/C Life Extender detects pressure that s too high or low, and too much or too little voltage. Then, it protects expensive system components from being damaged, and saves you maintenance costs and downtime. Pressure Protection When the ACX-10 detects persistent high or low system pressure, it disengages the A/C clutch until the pressure returns to the normal, safe operating range. Voltage Protection The ACX-10 detects over- and under-voltage conditions, and temporarily disengages the A/C clutch until the voltage returns to the normal, safe range. Starter Motor Protection The ACX-10 unburdens the starter motor and extends its life by delaying the A/C clutch engagement until 15 seconds after ignition. 551
