APU's I've had were supplemented with oil fired Bunk Heaters such as Webastos, Espar etc. For example, on a Webastos unit, it may have a separate control which looks like a dial. The truck has to be off and not running in order for it to work. Lift up your bottom bunk and have a look. If you have a square looking box with ducting tubes coming out of it, that's part of the APU A/C unit.

Look beside it. If there's another box, usually rectangular in shape, and a vent coming directly out of it and located on the under side of your bunk, that would be your bunk heater. You can also check the bunk area for separate heater controls.

The images below may or may not be what you have, but no harm in checking. The one on the left is for an Espar bunk heater and the one on the right (The Dial) is the control unit for a Webastos bunk heater.

Could be a digital control for newer units. It may be located just below the bunk as well. See if you have something similar and more help could be provided whether you have this or not. Just need to know more info. Don't get impatient with the heat knob.

It takes a good 5-10 minutes for the unit to warm up and the fan to kick on before you hear something. The same with the shutdown, the unit will blow until it cools down then it will shut off.

You can go outside and look at the little heater exhaust pipe and it will puff smoke in the warm up stage. Then you know it's working. Thermo King Tripacs have the ability to add aftermarket heaters like Espar and Webasto are the big ones.

Most are hooked up independently but might share duct work or the blower. It's up to the installer what route he wants to go as you have a few choices. Lift the bunk up and you'll see all the guts. Each one has their own website with how to use the different controls or how to find the trouble codes.

By using TriPac, drivers can reduce fuel cost, rest comfortably during stops and comply with local, state and federal anti-idle laws. 7.5 hp 2 cylinder diesel engine - EPA Tier II TriPac System. Thermo King TM-15-XD compressor for air conditioning The TriPac system includes several major components:. Diesel fuel-fired sleeper compartment air heater. An APU (auxiliary power unit).

Figure 6: Condenser Figure 5: TriPac APU Condenser Auxiliary Power Unit The TriPac Air Conditioning Condenser is mounted on the The TriPac APU contains the diesel engine, air conditioning back of the truck cab. Compressor, alternator and engine power switch. (Evaporator installed under sleeper cab bunk) Heater Evaporator The TriPac Heater is typically installed in the cargo The TriPac air conditioning Evaporator is typically installed compartment under the truck cab sleeper compartment. It under the bunk in the truck cab sleeper compartment.

Air ducts draws fuel from the truck’s diesel fuel tank and electric power. Compressor The TriPac air conditioning compressor is mounted in the TriPac APU and is driven by the TriPac engine. Refrigeration lines connect the compressor to the TriPac air conditioning condenser on the back wall of the truck cab and the evaporator, usually mounted under the truck sleeper compartment bunk.

9/06, it is part of the binary pressure closes to allow compressor operation. Switch, mounted on the receiver-drier, typically near the TriPac condenser. On models manufactured during 9/06 and after, a High Pressure Cutout Switch (HPCO) is located at the receiver/drier. The CLC option is designed for warm climate operation and switch opens the engine will shut down and an “Eng” Alarm also to isolate the TriPac system from the tractor engine Code will be displayed on the HMI. Typical causes for an open coolant if desired.
