NOTE: The APU requires periodic maintenance. Ensure you have access to internal components (i.e. oil filter, air filter,
fuel filter and oil filter). The Diamond comes filled with long life coolant. Consult the truck owner prior to altering the vehicle in any way.
CAUTION: Trucks with longer chassis should have the APU mounted closer to the sleeper unit to avoid obstacles such as railway crossings, speed bumps, curbs, etc. Before beginning installation of the Diamond system, disconnect the vehicle’s batteries. If truck is equipped with a coolant valve, valve must be fully opened before starting APU.
