Refrigerant OilObserve the following precautions when working with or around refrigerant oil:

RefrigerantAlthough fluorocarbon refrigerants are classified as safe, observe caution when working with refrigerants or around areas where they are being used in the servicing of your unit.

WARNING: Always wear goggles or safety glasses to protect eyes from refrigerant oil contact.

WARNING: Protect skin and clothing from prolonged or repeated contact with refrigerant oil. Rubber gloves are recommended.

WARNING: Wash thoroughly immediately after handling refrigerant oil to prevent irritation.

DANGER: Fluorocarbon refrigerants may produce toxic gases. In the presence of an open flame or electrical short, these gases are severe respiratory irritants CAPABLE OF CAUSING DEATH.

DANGER: Fluorocarbon refrigerants tend to displace air and can cause oxygen depletion which could result in DEATH BY SUFFOCATION. Provide adequate ventilation in enclosed or confined areas.

Unit DescriptionIntroductionThe Thermo King TriPace TM is an electric, battery-based Auxiliary Heating & Cooling Temperature Management System. The TriPace allows drivers to reduce unnecessary truck engine idling, conserve diesel fuel and save money.

With no diesel engine, the TriPace runs clean and emission-free, and is significantly quieter than engine-based APU systems. A fuel-fired air heater provides sleeper compartment heat in cold conditions. An air conditioning system provides sleeper compartment cooling in hot conditions.

Noise dampening construction assures quiet operation. An optional inverter provides 115 Vac power to operate on-board appliances.

TriPace batteries are automatically charged by the tractor alternator when the tractor is on the road.

An optional 115 Vac to 12 Vdc converter provides an additional source of power that will extend operation time. Must be plugged into an external 115 Vac, 15 Amp source.

Maximum climate control time is controlled by the total available power reserve in the TriPace batteries. To achieve maximum run time the operator should take steps to conserve power reserve by reducing power consumption, especially when outside temperature is high. Suggested steps include:

• Keep window curtains closed to reduce radiant heat that will increase cab temperature.

• Close curtain between cab and sleeper overnight to reduce air conditioning load.

• Limit the on time and number of cab lights and accessories to reduce battery power drain.

• Limit the on time and number of devices or appliances connected to the optional AC Power Inverter to reduce battery power drain.

system to maximize battery life and support deep discharge cycles. They provide increased power storage capacity for the system.

Smart Charging Modules (SCM)Each pair of batteries is connected to a Smart Charging Module (SCM). The SCMs control current flow to and from the batteries based on commands from the Main Controller. The SCM can be in one of three modes (not selectable by the driver):

• Charge Mode allows current to flow into the TriPace

batteries.

• Discharge Mode allows current to flow out of the TriPace

batteries.

• Null Mode prevents flow of current in either direction.

Control CircuitsThe control circuits operate on 12 Vdc supplied by the system batteries.

Power SourcesAll of the batteries onboard the truck, including the TriPace

system batteries, are a reservoir of electrical power. When the truck is parked the TriPace system, and any other electrical devices are in use, the power in this reservoir is being consumed. The faster the power is consumed, the sooner the power reservoir will be empty.

NOTE: Use of truck accessories such as lights, refrigerators, TVs, etc. draws power from the batteries and will compete with the climate control electrical demand of the TriPace

system. Heavy use of these devices and/or use of the optional 12 Vdc to 115 Vac Power Inverter will reduce the potential run time of the TriPace system. In addition, high ambient temperature will cause near continuous operation of the TriPace air conditioning system. This increased electrical demand will reduce the number of hours the system can control cab temperature. In high ambient conditions the driver should reduce the use of electrical accessories to a minimum to extend air conditioning time.

The TriPace power management technology makes the most efficient use of available power. The TriPace system may draw from the truck batteries and TriPace battery pack at same time. There is a Current Sensor in the interconnect cable between the TriPace batteries and truck batteries. It provides the Main Controller with information to help manage power flow. A pair of Smart Charging Modules (SCM) monitor and control power flow to and from the TriPace batteries. The SCMs provide the Main Controller with battery status information. The TriPace

system can draw as much as 100 amps during full air conditioning demand.

Power for the TriPace system comes from the following three sources. All system power is sent to a main fuse block in the TriPace battery box.

TriPace Battery Box: The TriPace Battery Box is the primary power source for the TriPace system.

Truck Batteries: The OEM truck battery bank is the secondary power source for the TriPace system.

Shore Power Converter (option): The Shore Power Converter is a 115 Vac to 12 Vdc power converter that provides low voltage power to the system. The Converter will help extend operation of the system before the batteries are depleted when the truck is parked and plugged into 115 Vac external or "Shore Power." During moderate ambient temperature conditions with moderate air conditioning demand the converter may support the system without draining the batteries. During high ambient temperature conditions with high air conditioning demand the converter will extend the operating time before the batteries are depleted. The Converter may also act as a secondary battery charging method during periods of low air conditioning or heating demand. The Converter is mounted in the cab, usually under the bunk. If the Shore Power Converter is plugged in while TriPace and all truck systems are off the converter will charge the truck batteries.

If shore power is available, it should be connected when the batteries are near full charge to receive the full extended run time benefit of the shore power converter.

Power Inverter (Option)The optional 1000 watt Pure Sine Wave Power Inverter provides 115 Vac "Hotel Power" for the driver. It changes the low voltage DC available from the truck batteries to high voltage AC. The Inverter is mounted in the cab, usually under the bunk.

NOTE: Use of the Power Inverter will reduce the total time the air conditioning system is able to operate.

Truck IntegrationThe TriPace APU system is integrated with the following Truck systems.

Truck Batteries: The truck’s own batteries provide part of the power for the TriPace system. Four 12 Vdc batteries must be connected to provide basic 12 Vdc output. For optimum system performance the truck battery pack should be upgraded to a type recommended by Thermo King. These batteries have been specifically designed for the TriPace system to maximize battery life and support deep discharge cycles. Shorter system runtime will be experienced without the battery upgrade.

Alternator: The truck’s alternator provides primary battery charging for the system while the truck is driving. With some applications or truck operation profiles, such as short drive times or high system demand, increased battery charging capacity may be required. To provide the additional charging capacity the alternator and charging cables may need to be upgraded to 270 amps.

Ignition Switch: When the truck ignition switch is in the ON or RUN position a signal is sent to the TriPace Main Controller. After a 3 minute "Pull ahead" time delay the TriPace

system will be turned off (disabled) and the system will begin a shutdown sequence. When shutdown sequence is complete the TriPace system does not draw power from the batteries. The time delay prevents short cycling the TriPace

system during short duration engine operation.

If the truck engine is still running when the 3 minute timer expires the battery charging process will begin. When the truck ignition is turned off the TriPace system is defaulted off (disabled) and must be turned on (enabled) by the driver.

Operation NotesIf theTriPace system is operating and the truck ignition is turned on, the system will initiate a 3 minute "Pull Ahead" timer. If the truck ignition is still on when the timer expires the system will enter a shutdown sequence.

If system is cycled off, it will not restart until a shutdown sequence is completed.

When changing between operating modes the new mode will not initiate immediately. A 2 second delay will allow changing back or to another selection to avoid momentary mode starts.

The TriPace System is OFF by default. When the truck ignition is turned off the driver must re-enable the system by pressing the ON Button (left knob) on the HMI.

The Evaporator fan mode default is AUTO when Air Conditioning is selected and OFF when Heat is selected.

During Air Conditioning operation the compressor is limited to five ON events per hour. This will prevent short cycling of the system. The system will reset one hour after the first event.







During HEAT operation the heater is limited to five ON events per hour. This will prevent short cycling of the system. The system will reset one hour after the first event.

High electrical accessory use and high ambient temperature will shorten operating time.

Battery Charging While Truck Is RunningCharging amperage is provided by the truck alternator. With some applications or truck operation profiles, such as short drive times or high system demand, increased battery charging capacity may be required. To provide additional charging capacity the alternator and charging cables may need to be upgraded to 270 amps.

NOTE: While the truck is idling there may not be enough amperage produced by the alternator to effectively charge the batteries. Many alternators must be turning a minimum of 1,200 RPM before effective battery charging is available.

Battery charging occurs in progressive stages. This prevents an extremely high charge rate. The process begins when the truck engine is started. The Smart Charging Modules (SCMs) will be put in Null mode. All TriPace batteries will be isolated. The truck’s batteries will be charged first.

Charging Process The TriPace Main Controller will begin adding one battery at a time to the charging process if there is excess charging capacity available from the alternator. Each SCM is capable of charging one battery at up to 40 amps.

• First, the Main Controller will put one of the SCMs in Charge mode, charging the battery with the lowest state of charge. If system voltage does not drop significantly, the SCM will remain in Charge mode. If system voltage does drop, the truck batteries are not sufficiently charged. The SCM will return to Null mode for a time then retry. SCM will continue trying to engage Charge mode until it is successful.

• Once the first SCM is in Charge mode for a time the Main Controller will attempt to add the second SCM to the charging process. It will perform the same process until it has both SCMs charging one battery each. SCMs will switch between their batteries until all batteries are fully charged. Total battery charging time is expected to be 6 - 10 hours depending on depth of discharge, traffic, driving profile and alternator size.

• The six Battery Monitor bars will scroll up in green while the truck engine is running and alternator is charging. Battery charge state can be read at the HMI while the HVAC system is off by “bumping” the ON/OFF Button (knob) for less than one second.

Shore Power ChargingConnect the optional 115 Vac Converter to external Shore Power. A 15 amp 115 Vac power source is required. If the optional Shore Power Converter is installed and Shore Power is available, it should be connected to external power soon after the truck is parked.

System On: If the TriPace HVAC system is drawing less than the available 85 amp output of the Shore Power Converter, the truck battery pack may begin charging. Depending on driver feature selection, if the truck batteries become fully charged and there is excess charging capacity, the Main Controller may begin charging the TriPace batteries. It will use the same charging process as when the truck is running.

System Off: If the TriPace system and truck systems are off, only the truck batteries will charge. This is because the SCMs are defaulted to NULL with the TriPace and truck off,

preventing current from flowing to or from the TriPace

batteries. If the shore power charging feature is selected by the driver, the TriPace batteries will also charge.

First Aid: Electrical ShockIMMEDIATE action must be initiated after a person has received an electrical shock. Obtain immediate medical assistance if available.

The source of the shock must be immediately removed by either shutting down the power or removing the victim from the source.

If it is not possible to shut off the power, the wire should be cut with either an insulated instrument (e.g., a wooden handled axe or cable cutters with heavy insulated handles) or by a rescuer

wearing electrically insulated gloves and safety glasses. Whichever method is used do not look at the wire while it is being cut. The ensuing flash can cause burns and blindness.

If the victim has to be removed from a live circuit, pull the victim off with a non-conductive material.

DO NOT TOUCH the victim! You can receive a shock from current flowing through the victim’s body.

Use the victim’s coat, a rope, wood, or loop your belt around the victim’s leg or arm and pull the victim off.

After separating the victim from power source, check immediately for the presence of a pulse and respiration.

• If a pulse is not present, start CPR (Cardio- Pulmonary Resuscitation) and call for emergency medical assistance.

• If a pulse is present, respiration may be restored by using mouth-to-mouth resuscitation, but call for emergency medical assistance.

WARNING: Explosion or Fire Hazard. If you need to remove a battery, always remove the ground terminal from the battery first. Make sure all accessories are off so you do not cause a spark.

WARNING: Explosion or Fire Hazard. Remove all metal items, like rings, bracelets, and watches when working with lead-acid batteries. Lead-acid batteries produce a short circuit current high enough to weld metal to skin, causing a severe burn.

Unit DescriptionThe Thermo King Power Converter/Battery Charger converts 120 volts nominal A.C. to 13.6 volts D.C. As a power supply, its tightly controlled regulation allows the user to operate any 12 volt nominal D.C. load up to the converter’s rated output current. As a battery charger, the converter will maintain the battery, delivering its full-rated current when the battery capacity falls sufficiently low. The voltage is set to deliver its maximum current for the necessary period of time that minimizes undue stress to the battery caused by heating of its cells. This helps to ensure the longest possible life of the battery. Over time, as the battery nears its full capacity, the converter will float-charge the battery to prevent self-discharge of its cells.

Protection FeaturesThe Thermo King Power Converter/Battery Charger is designed with high quality components to help ensure years of continuous use. The unit is protected by multiple protection features for a long, trouble-free life.

• Reverse Battery Polarity Protection.

• Brown-Out Input Protection.

• Over-Current Protection - cycle by cycle peak limiting as well as rated current limiting to maximize the life of the converter.

• Over-Temperature Protection. In addition, the converter/charger is designed with a unique “proportional” fan control circuit. Fan speed is directly proportional to the converter’s internal ambient temperature. This enables the fan to turn on and off very slowly, minimizing unwanted fan-starting noise.

• The power supply is protected against reverse polarity on the DC output. If a battery or the unit is hooked up incorrectly, the fuses will blow and can be easily replaced. Always use the same size and style fuse that came with the converter. To change the fuses, use a screwdriver to loosen the screws and remove the fuses. Always replace the fuses with the same type and rating.

Unit OperationTurning the Inverter On and OffThe power switch on the inverter’s front panel turns the control circuit in the Thermo King Pure Sine Inverter on and off.

To toggle the inverter on and off from its front panel:

1. Press the inverter’s power switch button (for half a second) to turn On the inverter (from Off).

2. Press the inverter’s power switch button (for one second) to turn Off the inverter (from On).

NOTE: When the inverter’s power switch button is Off, the inverter draws no current from the battery.

WARNING: Risk of electrical shock. The unit’s power switch when turned off does not disconnect power from the Thermo King Inverter.

Operating Several Loads at Once If you are going to operate several loads from the Inverter, turn them on separately after you have turned the inverter on.

This will ensure that the inverter does not have to deliver the starting current for all the loads at once.

Turning the Inverter Off Between ChargesWhen the power switch is on but no power is being supplied to a load, the inverter draws less than 800 mA from the battery. This is a low current draw. It would take a week to discharge a 150 Ah battery at this current, so you don’t have to worry about excessive drain on your battery if you leave the inverter switched on for a few days.

If you are not planning to recharge your battery within a week or so, switch the inverter off.

Inverter Loads The Thermo King Pure Sine Inverter will operate many AC loads within its power rating. However, some appliances and equipment may be difficult to operate. Please see “Exceptional Loads” below carefully.

USB Loads Many USB-powered devices such as portable music (MP3) players, mobile phones, and video game players can be charged and powered safely via the standard USB port. However, some devices such as portable GPS receivers and certain cameras may not work and even cause damage if you use the USB cable that came with the product. Be sure that the device only accepts 5 volts and can be charged or powered using other sources of power. See the device’s owner’s guide under specifications for information.

Exceptional Loads Some induction motors used in refrigerators, freezers, pumps, and other motor operated equipment need high surge currents to start. The Thermo King Pure Sine Inverter may not be able to start some of these motors even though their rated current

draw is within the inverter’s limits. If a motor refuses to start, observe the VOLTS indicator while you are trying to start the motor. If the indicator drops below 11 volts while the Thermo King Pure Sine Inverter is trying to start the motor, this may explain why the motor won’t start. Make sure the length and diameter of the battery cables are appropriate. Check that the battery connections are good and that the battery is fully charged. If the cables are sized correctly, the connections are good, and the battery is charged, but the voltage still drops below 11 volts, you may need to use a larger battery.

Battery Charging Frequency When possible, recharge your batteries when they are about 50% discharged or earlier. This gives them a much longer life cycle than recharging when they are almost completely discharged.
