System information

SYSTEM OVERVIEW
DPF: What is it, why do you care?
The Diesel Particulare Filter (DPF) is a system that removes most of the black
soot particles from the exhaust of your diesel engine. This results in cleaner
air for everyone and much less black soot on your truck.
T he DPF also replaces the APU muffler and performs the noise reduction function.
APU Engine Oil
The APU engine oil must be CJ-4 compliant low ash oil ONLY.

CARB Regulations
The Federal Environmental Protection Agency now requires that class 8 trucks
with main engines of model year 2007 or newer be equipped with engines that
meet stringent regulations. These regulations are typically met by equipping the
main engine with a DPF. The California Air Resources Board has enacted a further
regulation that requires APUs used on these same trucks to meet similar regulations.
The ComfortPRO APU uses a DPF to meet these regulations when used within
California. This regulation went into force on January 1st, 2008. This regulation
does not apply to trucks with model year 2006 or older main engines.
If a truck with a 2007 or newer main engine has a ComfortPRO APU without a
DPF, the APU may be present on the truck but may not be uses while in California.
Failing to comply with this regulation/law may result in fines at the discretion
of CARB enforcement officers.
It is worth noting at the time this manual was written, only California had a
requirement to meet these regulations. However, other jurisdictions are
considering following California with this requirement.

If the unit is equipped with a DCP2, Model PG1060 is needed.
To distinguish b
etween the DCP and DCP2 controllers, look on the front face, top left corner,
of the controller. There will be a 'DCP2' logo on the DCP2 controller and there will be none on
the DCP controller.
