Unit Description The Thermo King TriPac EVOLUTION APU (Auxiliary cold-climate starts by exchanging coolant between TriPac and Power Unit) provides auxiliary heating, cooling temperature the truck engine. An optional inverter provides 120-volt power management that allows drivers to reduce unnecessary truck to operate on-board appliances.
Unit Description Auxiliary Power Unit (APU) Condenser The TriPac EVOLUTION APU is mounted onto the side of the The TriPac air conditioning condenser is typically mounted on tractor’s frame rails and contains the diesel engine, air the outside rear wall of the truck cab.
Unit Description Evaporator Heater The TriPac air conditioning evaporator is typically installed The TriPac heater is typically installed in the cargo under the bunk in the truck cab sleeper compartment. Air ducts compartment or under the truck cab sleeper compartment. It from the evaporator carry conditioned air to the sleeper draws fuel from the truck’s diesel fuel tank and is powered by compartment.
It is easily accessible to the driver and controls the heating, cooling and fan operation of the TriPac. If necessary, system operating parameters can be programmed by your Thermo King dealer. HMI Controller Engine On/Off Switch...
Unit Description Control Box and Fuses TriPac Options The control box is typically located in the bunk area. The Driver Convenience Package control box contains the circuit board and operates on 12 Volt DC supplied by the truck batteries. Includes 1,800 watt inverter and two GFI receptacles. 120 amp alternator provides quicker battery charging under heavy loads.
Unit Description Standby Truck Integration - with Closed Loop Cooling Dash-Mounted Selector Switch Allows the TriPac to run independently of tractor coolant and allows “limp home” capability in case of tractor alternator The switch allows the operator to disable the TriPac system failure.
A exhaust tube extension (also called a tailpipe) is available as Diamond plate top cover is available as an option. an option and must be installed on TriPac Evolution APU’s installed behind truck fairings, skirting, etc. The extension routes the APU’s diesel exhaust outlet to an open area to help prevent exhaust fumes from entering the passenger compartment.
Manual Pretrip Inspection Pretrip inspections are an important part of a preventative Structural: Visually inspect the unit for leaks, loose or maintenance program designed to minimize operating broken parts, and other damage. problems and breakdowns. Perform this pretrip inspection Coils: Make sure the condenser, evaporator and pre-cooler before every trip.
Operating Instructions HMI Control Panel Display The HMI (Human Machine Interface) is typically mounted in the bunk area of the truck cab. The operator can select the The operator can select these functions from the HMI: desired function of the system. It has three selector knobs and system condition display.
Operating Instructions On/Off Button Turn system Off: If system is on, press the Mode Selector knob for a minimum of 2 seconds to turn the system off. The On/Off Button is behind the left knob on the HMI. It NOTE: The following system functions are disabled when the provides several functions depending on how long the button is APU is turned off: pressed.
Operating Instructions Temperature Selector Temperature selection is accomplished by rotating the center Temperature Selector knob. It adjusts the desired cab temperature cooler (blue) or warmer (red). Adjust to operator comfort. The default represented range is approximately 65 - 80 F (20 - 27 C) in Cool Mode and 50 - 80 F (10 - 27 C) in Heat Mode.
Operating Instructions Fan Speed Selector System Condition Evaporator fan speed selections are Off, Low, Medium and Display Several LED indicators are on the left side of the HMI. High. Rotating the Fan Speed Selector knob clockwise will These provide additional System Condition information. increase fan speed, counterclockwise will decrease fan speed.
If the condition that caused the alarm still exists, during this time the compressor clutch will re-engage. the alarm will return. Refer to the TriPac EVOLUTION Diagnostic Manual TK 55739 for more information about During normal air conditioning operation the compressor alarm codes.
Operating Instructions Fan Mode Coil Temperature sensor to prevent frost buildup on the evaporator coil. If coil temperature falls below 32 F the The TriPac evaporator fan can be turned on with the Fan Speed compressor clutch is de-energized. When coil temperature rises Selector knob to provide additional air circulation in the above 45 F the compressor clutch is energized.
Operating Instructions Standby Truck Integration (Option) Dash-mounted selector switch is in the STANDBY position: • The TriPac system will enter Standby Mode. This allows An optional wire harness connects the truck ignition switch to the operator to disable the TriPac system without an input connection on the TriPac interface board.
Operation NOTE: This is not the recommended setting. Refer to the TriPac EVOLUTION Diagnostic Manual TK 55739 Section While Monitor Mode is active the APU will continue to start 3, Software Settings, Switch to Monitor for more information.
Operating Instructions Engine On/Off Switch The APU Engine On/Off Switch functions as a service switch. It allows maintenance personnel to disable the APU engine. WARNING: The unit may start automatically without This assures the engine will not crank even if the HMI On/Off warning if the Engine On/Off Switch is in the On button is pressed on.
Operating Instructions Alarm Codes Alarm Notification The TriPac control system continually monitors operation and can generate several alarm codes. If the unit has an alarm condition the operator will be notified by an illuminated Alarm Icon on the HMI Control Panel. The icon can be Yellow or Red.
Active alarms and those recently cleared by the operator can be operating. Along with the Red Alarm Icon, one of the read and cleared by a Thermo King service technician. shutdown alarm group names (ENG, ALT, ACS) will illuminate. This indicates the alarm falls into one of the three categories, helping to focus diagnosis and repair.
