Generac 6485 Scheduled Maintenance Kit for 20 kW Standby Generators, 999cc Engines

FITS 20KW, 22KW, 24KW, AND 26KW GENERAC STANDBY GENERATORS: Designed for air-cooled Generac, Honeywell by Generac, and Centurion by Generac standby generators with a 999cc V-Twin engine manufactured in 2013 or later
COMPLETE OEM SERVICE KIT WITH ALL REPLACEMENT PARTS INCLUDED: Contains one OEM air filter, one foam air pre-cleaner, one spin-on oil filter, and two pre-gapped spark plugs — every consumable component required for a full scheduled maintenance service
GENUINE GENERAC PARTS PROTECT ENGINE LIFE AND WARRANTY COMPLIANCE: Factory-engineered OEM components maintain the tolerances and performance standards required to keep your generator within Generac's factory warranty conditions at every service interval
INCLUDES ANGLED OIL FUNNEL, MICROFIBER CLOTH, AND REMINDER STICKER: The angled funnel prevents spills during oil changes, the microfiber cloth handles cleanup, and the maintenance tracking sticker records your next service date directly on the enclosure
SERVICE EVERY 200 HOURS OR 2 YEARS — ENGINE OIL NOT INCLUDED: Follow the factory-recommended interval to maintain reliability; generators in dusty environments may require more frequent service — purchase SAE 5W-30 full synthetic engine oil separately
STEP-BY-STEP INSTRUCTION MANUAL INCLUDED — NO SPECIAL TOOLS REQUIRED: The enclosed instruction manual guides you through each service step using standard hand tools, making this a straightforward DIY service for homeowners without professional technician experience
VERIFY YOUR ENGINE SIZE AND BUILD YEAR BEFORE ORDERING: This kit fits 999cc V-Twin engines built in 2013 or later only — check the model and serial number plate on your generator enclosure or owner's manual to confirm compatibility before purchasing

Generac 7006 Load Manager, 100 Amp, Efficient Wire-Free Technology, Customizable Load Prioritization, LED Status Display, Gray

BROAD GENERATOR COMPATIBILITY: Works with any single-phase standby generator that produces standard 60 Hz AC output, including Generac air-cooled and liquid-cooled models — single-phase 240V only, not for three-phase systems
SCALE UP TO 8 MODULES PER SYSTEM: Install up to eight 100A Load Managers on a single generator system to manage multiple large appliances independently, with each module requiring a unique priority number
WIRE-FREE FREQUENCY SENSING TECHNOLOGY: No control wires to the transfer switch are needed; the module monitors generator output frequency autonomously and sheds loads the moment Hz drops below threshold
NEMA 3R RATED FOR INDOOR OR OUTDOOR MOUNTING: Enclosure withstands rain, sleet, and ice formation across an operating range of -22°F to 122°F, sized at 7.0"H x 11.4"W x 5.3"D for flexible placement
8-LEVEL PRIORITY DIAL FOR CUSTOMIZED LOAD RECOVERY: Assign each module a unique priority 1–8; lower numbers recover power first after a shed event, with each step adding a 15-second staggered delay to prevent re-overload
GENERATOR LOCKOUT MODE BLOCKS NON-ESSENTIAL LOADS: Set any module to lockout to permanently prevent that appliance from drawing generator power during an outage, while still allowing it to run normally on utility power
EXTERNAL LED STATUS DISPLAY WITH 5 CODED STATES: Diagnose system status without opening the enclosure; solid green means load connected, 1-second flash means startup delay, and 3-second flash means 30-minute overload lockout is active
