Once the engine has started, check the APU for coolant, fuel, oil and exhaust
leaks. Place the APU cover on the unit.
With a multi-meter, check the voltage at the AC power outlet box in the sleeper of
the truck. Voltage should read between 120 to 125 volts AC.
Allow APU to run for approximately 10 minutes and check again for coolant, oil,
fuel and exhaust leaks. After checking the APU over thoroughly, test the heating and air
conditioning unit for proper operation. Allow the APU to run for 30 minutes with the
heating and air conditioning unit in operation. This will put a load on the APU and allow
the unit to build up more heat. At the end of the 30-minute time period, turn the heating
and air conditioning unit off and push the driver control panel switch to the OFF Position.
Remove the front cover and check for coolant leaks. If no leaks are visible, replace front
cover.
Congratulations, The installation is complete.
