Tripac Wiring Diagram Wiring Diagram Pictures Often when a tripac unit cooling system is refilled, air is trapped in the engine block and or under the thermostat. use the following procedure to bleed air out of the block and the cooling system: 1. place a clean container under the tripac bleed line to catch the coolant that is drained. 2. open bleed petcock on the tripac engine to allow. Arctic package (option) this option monitors engine coolant temperature during low ambient conditions and automatically starts the tripac 3 engine to heat the truck engine coolant. this keeps the truck’s engine warm allowing for easier sub zero cold starts. arctic package is only available for installation onto trucks with the standard truck.
Thermo King Tripac Wiring Diagram Page 43 specifications coolant system capacity (tripac engine only) 0.6 quarts (0.6 liters) 2.75 quarts (2.6 liters) with closed loop cooling engine coolant type: conventional conventional coolant (antifreeze) is green or blue green. units equipped with conventional coolant do not have an elc nameplate on the expansion tank. Tripac® evolution. Apu. the tripac 3 apu is mounted onto the side of the tractor’s frame rails and contains the diesel engine, air conditioning compressor, alternator, control box with fuses, and a engine on off switch. figure 5. tripac 3 apu shown. 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.

Cold climate starts by exchanging coolant between tripac and the truck engine. an optional inverter provides 120 volt power to operate on board appliances. an optional arctic package aids truck engine startups in cold weather by sensing low coolant temperature. the tripac is started to heat the coolant as required. figure 3: tripac ama572.
