SYSTEM CHECK
Important: Perform these steps only after the HVAC and all other components have been installed.
System Check
• Oil level in the APU engine, add oil if necessary.
• Electrical and plumbing connections are secure.
• Radiator coolant valves (if any) fully open.
APU First Time Start Up
Before first time starting use the priming pump to clear the air in the fuel line.
WARNING: Do not start or run the APU prior to purging the entire cooling system of air.
Failure to do so will result in APU engine failure.
WARNING: Do not operate the engine without the enclosure cover in place. Failure to do so may result in injury.
Completing the Installation
• Test all the functions of the APU and the HVAC.
• Replace vehicle access panels, fairings, interior components and hardware that was removed to facilitate the installation.
• Seal all holes made through the floor or walls of the truck bunk with suitable sealant such as expanding foam.
• Vacuum the interior of the cab/sleeper.
• Review the installation with the owner and instruct them on the proper operation of the Diamond Power Systems. Give the owner the Operator’s Manual.
• Complete all warranty cards and return to Diamond Power Systems.
