Ruud GEN12AD-V manual Clean Air Cooling System, Fuel System Inspection and Maintenance

Clean Air Cooling System

Generator maintenance consists of keeping the unit clean. Operate the unit in an environment where it will not be exposed to excesive dust, dirt, moisture or any corrosive vapors. Cooling air louvers on the enclosure must not become clogged with snow, leaves, or any other foreign material. To prevent generator damage caused by overheating, keep the enclosure cooling inlets and outlets clean and unobstructed at all times.

Check the cleanliness of the unit frequently and clean when dust, dirt, oil, moisture or other foreign substances are visible on its exterior/interior surface. Inspect the air inlet and outlet openings inside and outside the enclosure to ensure air flow is not blocked.
