Thermo King dealer. However, there are several general safety
practices you should be aware of:

DANGER: Always turn the TriPac Envidia HMI
Controller OFF while refueling the truck. Fuel
vapors could ignite if they come in contact with
TriPac Envidia electrical or heater components.

DANGER: Hazardous Voltage! The compressor and
compressor controller operates with 220Vac 1 phase
voltage. Voltages of this magnitude can be lethal. All
service should be performed only by a certified
Thermo King technician.

WARNING: Always wear goggles or safety glasses
when working with or around the air conditioning
system or battery. Refrigerant or battery acid can
cause permanent damage if it comes in contact with
your eyes.

WARNING: Exposed coil fins can cause painful
lacerations. Service work on the evaporator or
condenser coils is best left to a certified Thermo King
technician.

WARNING: Turn the unit HMI Controller Off before
opening the Battery Box or inspecting any part of the
unit.

CAUTION: Do not connect other manufacturer’s
equipment or accessories to the Thermo King
Envidia unit. This could result in severe damage to
equipment and void the warranty!

Safety Precautions

Inverter Operation Warnings

DANGER: Do not use an inverter in life support or
health care applications where a malfunction or
failure of the inverter could cause failure of a life
support device or medical equipment or signifi­cantly alter the performance of that equipment.

DANGER: Potentially lethal voltages exist within
the inverter as long as the battery supply is con­nected. During any service work, the battery supply
should be disconnected.

DANGER: Do not connect or disconnect batteries
while the inverter is operating from the battery
supply. Dangerous arcing may result.

CAUTION: Protect against possible electrical
shock hazards. If the inverter is operated in wet or
damp conditions a user-supplied, portable GFCI
(ground fault circuit interruptor) must be con­nected between each inverter receptacle and the
equipment it powers.

CAUTION: You may experience uneven perfor­mance results if you connect a surge suppressor,
line conditioner or UPS system to the output of the
inverter.

Safety Precautions

Refrigerant Oil

Observe the following precautions when working with or
around refrigerant oil:

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.

Refrigerant

Although 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.

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.

WARNING: Fluorocarbon refrigerants evaporate
rapidly, freezing anything they contact if accidentally
released into the atmosphere from the liquid state.

Unit Description

Suggestions to Maximize Run
Time

Maximum climate control time is controlled by the total avail­able power reserve in the TriPac Envidia and truck 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.

• Plug into shore power when available. An optional power
converter provides an additional source of power that will
extend operation time.

System Components

The TriPac Envidia system includes several major compo­nents:

• Battery Box

• Condenser

• Evaporator/Control Box

• HMI Controller

• Heater (Optional)

• 1000 Watt Inverter (Optional)

• AC/DC Shore Power Converter (Optional)

13

Unit Description

ARA2673

Battery Box

The battery box is mounted to the truck frame rail. The battery
box contains four Thermo King NXT Absorbed Glass Mat
(AGM) Deep Cycle batteries. These batteries have been specif­ically designed for the TriPac Envidia system to maximize bat­tery life and support deep discharge cycles. They provide
increased power storage capacity for the system. The batteries
are automatically charged by the tractor’s alternator when the
tractor is on the road.

Thermo King recommends that the tractor’s batteries also be of
the same type as the TriPac Envidia batteries for optimum per­formance and battery life.

IMPORTANT: Do not use the TriPac Envidia batteries to
jump start a vehicle. Severe damage to the TriPac Envidia
batteries and electrical system will result!

Unit Description

Evaporator/Control Box

The air conditioning evaporator/control box is typically
installed under the bunk in the truck cab sleeper compartment.
Air ducts from the evaporator/control box distribute cool air
throughout the sleeper compartment.

The base controller and the electrical connections for the indi­vidual component are located on the side of the evaporator.

Figure 3: Evaporator/Control Box Shown

Condenser and Receiver Drier

The air conditioning condenser is mounted on the back of the
truck cab. It contains a variable speed fan. The receiver/drier
and the ambient temperature sensor are integrated on the hous­ing

.

Figure 4: Condenser and Receiver Drier

15

Unit Description

HMI Controller

The HMI controller is typically mounted in the bunk area. The
HMI allows the driver to select the desired function of the sys­tem. It also provides alarm, battery level and system status
feedback to the driver. The HMI has three selector knobs and a
battery monitor display. The HMI also contains an integral Cab
Temperature Sensor that helps control cab temperature when
the TriPac Envidia air conditioning system is operating.

Figure 5: HMI Controller

Optional Heater

The optional fuel-fired air heater is typically installed in the

cargo compartment under the truck cab sleeper compartment. It
draws fuel from the truck’s diesel fuel tank and electric power
from the TriPac Envidia batteries.

Figure 6: Optional Heater

16

Unit Description

Control Circuits

The primary control circuits of the TriPac Envidia operate on
12 Vdc supplied by the TriPac Envidia batteries. The compres­sor control circuits operate on 230 Vac supplied by the Com­pressor Drive Module.

Power Sources

All of the on-board batteries of a truck with the TriPac Envidia
system can be thought of as a reservoir of electrical power.
When the truck is parked, the TriPac Envidia system, and any
other electrical devices in use, will consume the power in this
reservoir. The faster the power is consumed the sooner the 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 TriPac
Envidia 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 TriPac Envidia system. In addition,
high ambient temperature will cause near continuous opera­tion of TriPac Envidia air conditioning system and is aggra-

vated by lowering the setpoint. 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 TriPac Envidia power management technology will make
the most efficient use of the available power. The system will
draw from the truck batteries and TriPac Envidia battery pack
together. There is a Current Sensor around the interconnect
cable between the TriPac Envidia batteries and truck batteries.
It provides the Base Controller with information to help man­age power flow. A pair of Smart Charger Modules (SCM)
monitor and control power flow to and from the TriPac Envidia
batteries. The SCMs provide the Base Controller with battery
status information. The TriPac Envidia system may draw in
excess of 100 amps during full air conditioning demand.

17

Unit Description

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

#1- TriPac Envidia Battery Box: The TriPac Envidia Battery
Box is the primary power source for the TriPac Envidia sys­tem.

#2 - Truck Batteries: The OEM truck battery bank is the sec­ondary power source for the TriPac Envidia system.

#3 - Shore Power (Option): The optional 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 truck 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 TriPac
Envidia and all truck systems are off the converter will charge
the truck and TriPac Envidia 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.

Truck Integration

The TriPac Envidia APU system is integrated with the follow­ing OEM Truck systems.

OEM Truck Batteries

The OEM truck batteries provide part of the power for the Tri­Pac Envidia system. For base level system performance, there
must be four 12 Vdc Group 31 batteries connected to provide
12 Vdc output. For optimum system performance the truck bat­tery pack should be upgraded to four AGM type deep cycle
batteries. These batteries have been specifically designed to
support deep discharge cycles. Shorter system runtime will be
experienced without the battery upgrade.

18

Unit Description

Alternator

The OEM truck alternator provides primary battery charging
for the system while the truck is driving. A 270 amp alternator
is the minimum required to support the TriPac Envidia system.
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 300 amps or above. Alternator and harness
upgrades must approved by the truck OEM.

Ignition Switch

When the truck ignition switch is turned to the On or Run posi­tion a signal is sent to the TriPac Envidia Base Controller. A
three minute “Pull ahead” timer is activated and the system
will continue to operate. If the switch is still on after three min­utes the TriPac Envidia system will be turned off (disabled)
and the system will begin a shutdown sequence. Once the
sequence is complete, the system does not draw power from
the batteries. The time delay prevents short cycling the system
during short duration engine operation. If the truck engine con­tinues to run, the battery charging process will begin. When the
truck ignition is turned off, the TriPac Envidia system is
defaulted off (disabled) and must be turned on (enabled) by the
driver.

Protection Devices

Air Conditioning System

The Evaporator/Control box contains sensors that protect the
Air Conditioning system.

• High Pressure Cutout (HPCO) switch monitors air con-
ditioning system pressure and generates an alarm if abnor­mally high system pressure occurs.

• Compressor Overload Switch (OLS) monitors compres-
sor temperature and protects against high compressor tem­perature.

Electrical System Fuses

The electrical system is protected by a number of fuses. The
fuses are located on the base controller, on the fuse block in the
TriPac Envidia battery box, and in some of the harnesses.

See “Fuses” in the Specifications Chapter for a list of the fuses
and their locations.

IMPORTANT: All fuse replacement should be done only by a
qualified service technician.

19

Manual Pre-Trip Inspection

Pre-trip inspections are an important part of a preventative
maintenance program designed to minimize operating prob­lems and breakdowns. Perform this pre-trip inspection before
every trip.

IMPORTANT: Contact your nearest Thermo King Dealer
immediately if problems are found.

NOTE: Pretrip inspections are not intended to take the place
of regular maintenance inspections.

20

Before Starting the TriPac Envidia Unit

Structural: Visually inspect the unit for leaks, loose or broken

parts, and other damage.

Condenser and Evaporator: Check and clean evaporator
return air filter. Make sure the condenser and evaporator coils
are clean and free of debris.

Ducts and Vents: Verify that air conditioning and heating
vents are free of obstructions. Verify that air ducts under bunk
are not crushed or kinked.

Heater:Verify heater air intake tube and exhaust pipe under
truck are in place, not kinked and free of obstructions.

General: Listen for unusual noises and vibrations.

System Alarm Icons

The alarm icon (Yellow or Red) will alert the driver that an
abnormal condition exists.

• Yellow = Check Alarm. This type of alarm indicates the
system has an abnormal condition that should be checked
by a Thermo King technician at the next opportunity. The
system will continue to operate but may have reduced
capacity.

• Red = Shutdown Alarm. This type of alarm indicates a
system fault that should be checked by a Thermo King
technician immediately. The system will not operate with
this alarm active.

To Clear Alarms: Turn the system Off then On at the HMI.
Active alarms will clear. The Alarm icon should go out. If it
does not or immediately returns the alarm condition still exists.

Alarms may also be cleared while the system is on. Bump the
On/Off button three times then hold it for five seconds. Bump
three more times.

IMPORTANT: If system alarms continue to appear, contact
an authorized Thermo King Dealer.

Operating Instructions

Battery Alarm Icon

If the system has turned off for low power reserve, it may be
turned on by pressing the On/Off button on the HMI for one
second. The system batteries should have been fully charged
by running the truck before turning the system on again. If the
batteries are not charged, the system may immediately turn off
for low power reserve or have very short run time. Repeated

partial charging then fully discharging the system batteries
will reduce battery life.

• Red = System Off due to low power reserve. System Volt­age has fallen below 12.3 Vdc. The SCMs have switched
to Null and HVAC systems have been disabled preventing
further discharge of the system batteries.

NOTE: The truck batteries will be the last voltage available.
The HVAC system will continue to operate after the TriPac
Envidia batteries are depleted.

Battery Charging

With Truck Running

Charging amperage is provided by the truck alternator. A 270
amp alternator is the minimum required to support the TriPac
Envidia system. For many applications or truck operation pro­files, such as high tractor duty load, high driver “Hotel Load”,
extended layover duration, high ambient temperature or short
drive times between layovers, increased battery charging
capacity may be required. Undersized alternators will increase
TriPac Envidia charge time. The truck alternator will spend a
higher percentage of operating time at maximum output. This
may shorten the life of the truck alternator.

To provide the additional charging capacity, the alternator and
charging cables may need to be upgraded to 270 amps or more.
Verify that alternator and charging cable upgrades are accepted
by the OEM.

Battery charging will take place in progressive stages that pre­vents an extremely high alternator charge rate. The process
begins when the truck engine is started. The SCMs will be put
in Null mode. All TriPac Envidia batteries will be isolated.
The truck batteries will begin charging first.

Operating Instructions

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

If the TriPac Envidia system is on when the truck is started, the

three minute Pull Ahead timer must expire followed by a four
minute system check before the charging process will begin. If
the TriPac Envidia system is off when the truck is started, the
Base Controller wakes up to check truck ignition status period­ically. If it is on, the charging process will begin.

The TriPac Envidia Base Controller will monitor System Volt­age. When it rises above 13 Vdc, the Base Controller will
begin adding one SCM 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 40 amps. First
the Base Controller will check each battery. It will put one of
the SCMs in Charge mode. It will then choose to charge the
battery with the lowest state of charge. As a result, SCM1 bat­tery A may not be the first to begin charging.

NOTE: A battery must be above 9 volts for the SCM to recog­nize it for charging. A battery below this voltage should be
tested then externally charged before adding it back into the
system. A red flashing LED on the SCM will indicate a bat­tery that is under voltage and isolated.

If System Voltage does not drop significantly when a battery is
added, the SCM will remain in Charge mode. If System Volt­age does drop there is insufficient reserve charging capacity,
the truck batteries are not sufficiently charged. The SCM will
return to Null mode for 15 minutes then retry. The SCM will
continue trying to engage Charge mode until it is successful.

Once the first SCM is in Charge mode for a time the Base Con­troller will attempt to add the second SCM to the charging pro­cess. It will perform the same steps until it has both SCMs
charging one battery each. The truck alternator is now charging
six batteries; four in the truck and two in the TriPac Envidia
battery box. The SCMs will bring their first batteries to 80%
state of charge then switch to their second batteries until all
batteries are at 80% state of charge. The SCMs will switch
back to the first battery to finish charging to 100% followed by
the second battery. Once charging has started, if System Volt­age falls below 11.5 Vdc, the TriPac Envidia battery charging
will stop.

Total battery charging time is expected to be 4 to 8 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 selector for less
than one second.

Operating Instructions

When Connected to Shore Power

Connect the optional 115 Vac to 12 Vdc Shore Power Con­verter to external Shore Power. This requires a 115 Vac, 15
amp power source. If the optional AC to DC Shore Power Con­verter is installed and Shore Power is available it should be
connected to external power as soon as possible after the truck
is parked. The converter will provide 13.6 Vdc at up to 85
amps to the truck batteries. This additional amperage helps to
keep the truck batteries at a high state of charge while support­ing driver “Hotel Load” and power sharing with the TriPac
Envidia system. The primary function of the AC to DC Shore
Power Converter is to extend HVAC operating time.

With HVAC System On

If the combined amp draw from the truck batteries of the Tri­Pac Envidia HVAC system, truck systems and DC to AC
Power Inverter is less than the available 85 amp output of the
AC to DC Shore Power Converter, the truck battery pack may
begin charging. The TriPac Envidia batteries will not charge
with the HVAC system on.

With HVAC System Off

The Base Controller monitors System Voltage. While the sys­tem is off, the Real Time Clock momentarily wakes up the
Base Controller periodically (every five min during first three
days, every 15 min days 3-6, once per hour after day 6). It will
check System Voltage. If it rises above 13.5 Vdc the system
will automatically recognize Shore Power Charging and enter
charge mode. This will allow the SCMs to charge the TriPac
Envidia batteries. If System Voltage falls below 13 the
charging of the TriPac Envidia batteries will stop. The truck
batteries will continue to charge.
