Mobile Generators Factory-Installed Options Fuel/Water Separator See Graphic: wc_gr001705 The fuel/water separator separates water from the fuel on models with Isuzu engines. Empty the separator water bowl (a) as needed by opening the water bowl drain (b). The separator element should be changed each time the fuel filter is changed—approximately every 600 hours of operation.
Factory-Installed Options Mobile Generators Electronic Governor See Graphic: wc_gr001714, wc_gr001715, wc_gr001716, wc_gr001717 The electronic governor option consists of an electronic module (a or b) and an electronic actuator (c or d). The module senses rotation of the flywheel, then sends a signal to the electronic actuator that governs the fuel injection system.
Mobile Generators Factory-Installed Options LCD Strip Heater See Graphic: wc_gr001724, wc_gr001725 The LCD strip heater option includes a thermostat module (a) and a clear heater strip that is bonded to the LCD (b) of the ECM. The purpose of the strip heater is to prevent the LCD from being damaged by extremely cold temperatures.
Factory-Installed Options Mobile Generators Low Coolant Shutdown See Graphic: wc_gr001708 The low-coolant shutdown system consists of an electronic sensor that monitors coolant level. The sensor (a) is mounted to the radiator and wired into the ECM. The sensor probe (b) is submerged in radiator coolant.
Mobile Generators Factory-Installed Options Lube Level Maintainer See Graphic: wc_gr001711, wc_gr001712, wc_gr001713 The lube level maintainer system protects the engine from low oil levels by providing an additional 6-quart oil reservoir. Oil from the reservoir is gravity-fed from the oil reservoir (a) through the control valve (b) and into the engine oil pan as needed.
Factory-Installed Options Mobile Generators Temperature-Activated Shutters See Graphic: wc_gr001706, wc_gr001707 The shutters (a) are mounted to the top of the generator enclosure. The shutters are designed to keep the engine compartment warm, thus increasing engine temperature during cold weather operation. The shutters are activated through a wax-pellet actuator (b) that is connected to the generator's cooling system.
