There is nothing complicated about operating and maintaining your Thermo
King unit, but a few minutes studying this manual will be time well spent.

Performing pre-trip checks and enroute inspections on a regular basis will
minimize operating problems. A regular maintenance program will also help
to keep your unit in top operating condition. If factory recommended
procedures are followed, you will find that you have purchased the most
efficient and dependable temperature control system available.

All service requirements, major and minor, should be handled by a Thermo
King dealer for four very important reasons:

• They are equipped with the factory recommended tools to perform all
service functions

• They have factory trained and certified technicians

• They have genuine Thermo King replacement parts

• The warranty on your new unit is valid only when the repair and
replacement of component parts is performed by an authorized Thermo
King dealer

RRiisskk ooff IInnjjuurryy!!

Thermo King units may have options that allow for remote starting from a
fully off state. Turn the unit Microprocessor On/Off Switch Off before doing
inspections or working on any part of the unit.

Electrical Hazard

DDAANNGGEERR

HHaazzaarrddoouuss VVoollttaaggee!!

When servicing or repairing a temperature control unit, the possibility of
serious or even fatal injury from electrical shock exists. Extreme care must
be used when working with a refrigeration unit that is connected to a source
of operating power, even if the unit is not operating. Lethal voltage
potentials can exist at the unit power cord, inside the control box, at the
motors and within the wiring harnesses.

WWAARRNNIINNGG

RRiisskk ooff IInnjjuurryy!!

On SmartPower electric standby equipped units, always turn off the
external standby power source before handling, connecting, or
disconnecting the power cable. Always disconnect the standby power cord
before servicing the unit.

WWAARRNNIINNGG

HHaazzaarrddoouuss VVoollttaaggee!!

The unit On/Off switch must be turned Off before connecting or
disconnecting the standby power plug. Never attempt to stop the unit by
disconnecting the power plug.

WWAARRNNIINNGG

RRiisskk ooff IInnjjuurryy!!

The unit power plug must be clean and dry before connecting it to a power
source.

WWAARRNNIINNGG

HHaazzaarrddoouuss VVoollttaaggee!!

A certified electrician should verify that the proper standby power
requirements are being supplied before connecting to a new power source.

Low Voltage

IImmppoorrttaanntt:: Some SR-3 components are connected directly to un-switched

battery power. All connections and circuits labeled with a “2”
prefix are connected directly to battery power. Always
disconnect the battery before servicing the unit.

WWAARRNNIINNGG

LLiivvee EElleeccttrriiccaall CCoommppoonneennttss!!

Control circuits used in refrigeration units are low voltage (12 to 24 volts
dc). However, the large amount of amperage available can cause severe
burns if accidentally shorted to ground with metal objects, such as tools. Do
not wear jewelry, watches, or rings because they increase the risk of
shorting out electrical circuits and damaging equipment or causing severe
burns.

Refrigeration System Hazards

In the United States all technicians who maintain, service, repair, or dispose
of equipment that could release refrigerants into the atmosphere must be
EPA 608 certified. Thermo King recommends all service be performed by a
Thermo King dealer.

DDAANNGGEERR

HHaazzaarrddoouuss GGaasseess!!

Refrigerant in the presence of an open flame, spark, or electrical short
produces toxic gases that are severe respiratory irritants which can cause
serious injury or possible death.

DDAANNGGEERR

RReeffrriiggeerraanntt VVaappoorr HHaazzaarrdd!!

Do not inhale refrigerant. Use caution when working with refrigerant or a
refrigeration system in any confined area with a limited air supply.
Refrigerant displaces air and can cause oxygen depletion, resulting in
suffocation and possible death.

WWAARRNNIINNGG

PPeerrssoonnaall PPrrootteeccttiivvee EEqquuiippmmeenntt ((PPPPEE)) RReeqquuiirreedd!!

Refrigerant in a liquid state evaporates rapidly when exposed to the
atmosphere, freezing anything it contacts. Wear butyl lined gloves and
other clothing and eye wear when handling refrigerant to help prevent
frostbite.

Refrigerant Oil Hazards

WWAARRNNIINNGG

PPeerrssoonnaall PPrrootteeccttiivvee EEqquuiippmmeenntt ((PPPPEE)) RReeqquuiirreedd!!

Protect your eyes from contact with refrigerant oil. The oil can cause serious
eye injuries. Protect skin and clothing from prolonged or repeated contact
with refrigerant oil. To prevent irritation, wash your hands and clothing
thoroughly after handling the oil. Rubber gloves are recommended.

NNOOTTIICCEE

MMaatteerriiaall DDaammaaggee!!

Wipe up spills immediately. Refrigerant oil can damage paints and rubber
materials.

First Aid

EELLEECCTTRRIICCAALL SSHHOOCCKK

Take IMMEDIATE action after a person has received an electrical shock. Get
quick medical assistance, if possible.

The source of the shock must be quickly stopped, by either shutting off the
power or removing the victim. If the power cannot be shut off, the wire
should be cut with an non-conductive tool, such as a wood-handle axe or
thickly insulated cable cutters. Rescuers should wear insulated gloves and
safety glasses, and avoid looking at wires being cut. The ensuing flash can
cause burns and blindness.

If the victim must be removed from a live circuit, pull the victim away with a
non-conductive material. Use wood, rope, a belt or coat to pull or push the
victim away from the current. DO NOT TOUCH the victim. You will receive a
shock from current flowing through the victim’s body. After separating the

Welding Precautions

Take precautions before electrically welding any portion of the unit or the
vehicle to which it is attached. Verify that welding currents are not allowed to
flow through the unit’s electronic circuits.

Observe the following precautions when welding to avoid damaging
electronic components.

• If the microprocessor has a power switch, turn it OFF before connecting
or disconnecting the battery.

• Disconnect power to the unit.

• Disconnect all wire harnesses from the microprocessor.

• If there are any electrical circuit breakers in the control box, switch them
OFF.

• Close the control box.

• Components that could be damaged by welding sparks should be
removed from the unit.

• Use normal welding procedures, but keep the ground return electrode as
close to the area being welded as practical. This will reduce the likelihood
of stray welding currents passing through any electronic circuits.

Unit Description

General Description

The T-1090 SPECTRUM™ is a self-powered multi-temperature cooling and
heating unit designed for straight trucks. The condensing unit is mounted on
the front of the truck cargo box. The remote evaporators are located in up to
three individual compartments inside the cargo box. The unit uses Chlorine
free R-404A refrigerant.

The basic models provide the following:

SSttaannddaarrdd UUnniitt ((MMooddeell 3300)):: Cooling and hot gas heating on engine
operation.

SSmmaarrttPPoowweerr™™ UUnniitt ((MMooddeell 5500)):: Cooling and hot gas heating on engine
operation and electric standby operation.

A three cylinder, EPA Tier 4, special clean and quiet diesel engine powers the
unit when in the truck is in route. SmartPower (Model 50) units are also
equipped with an electric motor for standby power operation while the truck
is stationary.

The SR-3 microprocessor based temperature control system and in-cab HMI
controller manage unit functions. CYCLE-SENTRY™, an exclusive Thermo
King feature, automatically starts and stops the unit according to
temperature demands. This continuous monitoring function optimizing the
unit’s performance and reduces fuel consumption while maintaining
temperature in multiple compartments.

The on-board Pretrip unit self check feature can be run before beginning the
daily distribution route to identify any possible unit malfunctions and help
prevent down time.

Engine

Engine power for the T-1090 SPECTRUM is provided by the TK380F, a three
cylinder, EPA Tier 4, special clean and quiet diesel engine rated at 19.3
continuous horsepower (14.4 kW) at 2425 RPM. A belt drive system transfers
energy to the compressor and alternator.

ELC (Extended Life Coolant)

The maintenance interval for ELC is eight years or 15,000 hours. A nameplate
near the coolant expansion tank identifies units with ELC. This coolant is Red
instead of the previous Green or Blue-Green coolants.

Figure 6. ELC (Extended Life Coolant) Nameplate

IImmppoorrttaanntt:: Only OAT extended life coolants (Chevron Delo® XLC or

equivalent) should be added to Thermo King systems.
Conventional coolants should not be used (Typically identified
by green or blue-green color). If a conventional coolant is
combined with the Thermo King factory fill up to 25% by volume,
the coolant must be changed at the next service opportunity.
Above 25%, the coolant must be changed immediately.
Conventional coolants dilute/interact with the additive packages
of extended life coolant which significantly reduces the service
life of the coolant.

NNoottee:: The use of 55/45% pre-mixed ELC is recommended to ensure that

deionized water is being used. If 100% full strength concentrate is
used, deionized or distilled water is recommended instead of tap
water to ensure the integrity of the cooling system is maintained.

Clutch

The centrifugal clutch engages fully at 600 ± 100 RPM on engine operation,
constantly turning the compressor, alternator, and fans at both high and low

TK 56704-1-OP-EN

UUnniitt DDeessccrriippttiioonn

speed. The clutch isolates the engine from the belt drive system during
electric standby operation on Model 50 units.

Reciprocating Compressor

The T-1090 SPECTRUM features the X430P, 4 cylinder reciprocating
compressor with 30.0 cu in (492 cc) displacement.

HMI Controller

The HMI Controller communicates with the Base Controller (located inside
the control box) and is used operate the unit and display unit information. It
also provides access to all the controller functions and menus.

CYCLE-SENTRY™™ Start/Stop System

The CYCLE-SENTRY Start/Stop fuel saving system provides optimum
operating economy.

WWAARRNNIINNGG

RRiisskk ooff IInnjjuurryy!!

The unit can start at any time without warning. Press the OFF key on the
HMI control panel and place the microprocessor On/Off switch in the Off
position before inspecting or servicing any part of the unit.

The CYCLE-SENTRY system automatically starts the unit on microprocessor
demand and shuts down the unit when all demands are satisfied.

The system monitors and maintains the compartment temperature, the
engine block temperature, and battery charge levels at a point where quick,
easy starts are possible.

Defrost

Frost will gradually build up on the evaporator coils as a result of normal
operation. Periodically this frost must be melted to prevent a loss of cooling
and airflow.

Defrost is accomplished by passing hot refrigerant gas through the
evaporator coil, thus melting the frost (or ice). Melted frost drains out of the
unit onto the ground through the drain tubes.

Defrost can be initiated at any time the evaporator coil temperature is below
42 F (5.5 C).

20

TK 56704-1-OP-EN

UUnniitt DDeessccrriippttiioonn

There are two methods of defrost initiation:

SSRR--22//SSRR--33 MMiiccrroopprroocceessssoorr CCoonnttrroolllleerr:: The Microprocessor Controller is
programmed to automatically initiate timed and forced defrost cycles. The
SR-2/SR-3 uses temperature sensors to determine if forced defrost is
required.

MMaannuuaall DDeeffrroosstt:: Manual Defrost allows the operator to initiate a defrost
cycle by pressing the Defrost key. See “Initiating a Manual Defrost Cycle.”

TracKing™

T-90 series units are equipped with a wireless communication platform that
offers fleet owners the ability to monitor their refrigerated units. Cellular,
GPS, and Bluetooth capabilities communicate with Thermo King’s web­based TracKing™ application, and Bluetooth with the Thermo King Reefer
App. A third party interface offers a gateway for telematics providers to
communicate with the Thermo King unit. To learn more about the TracKing
features, contact your Thermo King dealer.

SmartPower Electric Standby (Model 50 Units Only)

The SmartPower Electric Standby option allows the unit to be operated on
either the diesel engine or external electric power.

DDAANNGGEERR

HHaazzaarrddoouuss VVoollttaaggee!!

High voltage AC power is present whenever the unit is operating in the
Electric Standby mode and whenever the unit is connected to external
standby power. Voltages of this magnitude can be lethal. Exercise extreme
caution when working on the unit.

Alarms

Alarms may be one of four types as shown.

Log Alarms

Log Alarms are indicated for 60 seconds each time the unit is turned on. This
level of alarm serves as a notice to take corrective action before the
condition impacts unit performance. Maintenance items such as
maintenance hourmeter time-outs are Log Alarms.

When the unit is turned on, the display will show the Thermo King Logo and
the "Configuring System" message. If Log Alarm(s) are present, the Log
Alarm notice will appear on the display for 60 seconds as shown (Figure 61,

p. 53). The amber K symbol of the remote indicator alarm light (if installed)

will also be on during this period. The Standard Display will appear and the
remote indicator alarm light will go to the white T symbol after 60 seconds.

NNoottee:: The Alarm Icon does not appear on startup with log alarms present.

Check Alarms

Check Alarms are indicated by an Alarm Icon in the display. The amber K
symbol of the remote indicator alarm light (if installed) will be on. This level
of alarm serves as a notice to take corrective action before a problem
becomes severe. The unit will run with check alarms but some features and
functions may be inhibited.

Shutdown Alarms

Shutdown Alarms will be set if continued operation could cause damage to
the unit or the load. Shutdown Alarms are indicated by the following:

• The Alarm Icon will appear in the display.

• The display and backlight will flash on and off.

• The display will switch from normal to inverted and back to normal (light
areas become dark and dark areas become light).

• The remote indicator alarm light (if installed) will display only a row of
LEDs at the bottom.

Figure 62. Shutdown Alarm

Shutdown Alarms will force the unit into shutdown to prevent potential
damage to the unit or load. The unit will remain in shutdown until the
Shutdown Alarm is manually cleared. Exceptions are some engine and
electric Shutdown Alarms that become Log Alarms when switched to the
alternate operating mode (diesel to electric or electric to diesel).

Prevent Alarms

Prevent Alarms are also indicated by a steady Alarm Icon in the display. The
remote indicator alarm light (if installed) will be on. The unit will attempt to
resolve the situation as shown below:

• The unit will be temporarily shut down if a Prevent Alarm is active.

54

TK 56704-1-OP-EN

OOppeerraattiinngg IInnssttrruuccttiioonnss ffoorr PPrreemmiiuumm HHMMII CCoonnttrrooll PPaanneell

• The unit will remain shut down for a timed restart interval or until the
fault conditions are corrected.

• If the unit is in a temporary shutdown, Alarm Code 84 Restart Null will be
present along with the associated Prevent Alarm.

• The unit will restart and run (in most cases with forced reduced
performance) to determine if continued operation is possible. The unit
will run in this manner for a timed interval. If the unit is running with
forced reduced performance, Alarm Code 85 Forced Unit Operation will
also be present under some conditions.

• If the alarm does not re-occur during the timed running interval with
reduced performance, the unit will return to full performance to
determine if continued operation is possible. The unit will run in this
manner for a timed interval. If the unit is successfully able to return to full
performance for the timed interval without the alarm re-occurring, the
alarm is auto cleared and the unit will run normally.

• All Prevent Alarm events and conditions are logged by the ServiceWatch
Data Logger.

• In general, if the alarm condition re-occurs a defined number of times,
the alarm is set as a Shutdown Alarm and no further restarts are
possible.

NNoottee:: If the Restart After Shutdown feature in the Guarded Access Menu is

set for CONTINUOUS, an unlimited number of restart attempts are
allowed.

Pretrip Alarm Codes

If an alarm occurs during a Pretrip Test, the alarm code will be displayed as
Pretrip Alarm XX, where XX is the alarm code.

Alarm Codes When Switching Between Diesel and Electric

If a Shutdown Alarm occurs that affects only diesel mode operation and the
unit is switched to electric, the diesel mode Shutdown Alarm becomes an
electric mode Log Alarm. This allows the unit to run in electric mode without
clearing the Shutdown Alarm that is preventing diesel mode operation. If the
unit is switched back to diesel mode, the alarm again become a diesel mode
Shutdown Alarm and prevents unit operation.

In the same manner, if a Shutdown Alarm occurs that affects only electric
mode operation and the unit is switched to diesel, the electric mode
Shutdown Alarm becomes a diesel mode Log Alarm to allow diesel mode
operation. If the unit is switched back to electric mode, the alarm reverts to
an electric mode Shutdown Alarm and prevents unit operation. If the unit is

configured for electric to diesel autoswitch, it automatically starts and runs
in diesel mode if an electric shutdown occurs.

Alarm Code Notification

The Alarm Icon used in previous Thermo King controllers has been
incorporated. If a Check Alarm condition occurs, the Alarm Icon will appear
in the display as shown (Figure 63, p. 56).

Figure 63. Alarm Icon

Clearing Alarm Codes

Most alarm codes can be cleared conventionally from the Alarm Menu using

Selecting Sleep Mode

Normal CYCLE-SENTRY mode starts and stops the unit as required to
maintain the desired setpoint temperature, maintain the unit battery in a
charged condition, and keep the engine warm in cold ambient conditions.
Sleep Mode does not consider setpoint or maintain cargo temperatures - it
only keeps the engine warm and the unit battery charged. This is useful in
extremely cold weather or when the unit is to be out of service for an
extended time. Sleep Mode operates in both Diesel and Electric. In Diesel,
the unit will start and stop as required to maintain engine temperature and
battery charge. In Electric, the unit starts and stops as necessary to maintain
battery charge only.

When Sleep Mode is entered, the operator can program an automatic Wake­up Time up to a week away. Using this feature, the unit will automatically
restart and run normally at the determined time. If a Wake-up Time is
programmed, the operator can also program an automatic Pretrip Test when
the unit restarts.

Pretrip

A Pretrip Test verifies unit operation. This display allows a Pretrip Test to be
selected and initiated by the operator. If the Pretrip Test is entered with the
unit shut down, a Full Pretrip Test with device amp checks will be performed.
If the Pretrip Test is entered with the unit running in either diesel or electric
mode, a Running Pretrip Test is performed, but the device amps checks are
not performed. Test results are reported as PASS, CHECK, or FAIL when the
Pretrip Test is completed. If an alarm occurs during a Pretrip Test, the alarm
code will be displayed as Pretrip Alarm XX, where XX is the alarm code.

Pretrip Test Conditions

• Current unit settings are saved and restored at the end of the Pretrip Test
or if the unit is turned off and back on.

• Pretrip Test can be run in either Diesel or Electric Mode.

• The unit will auto switch from Diesel to Electric Mode or from Electric to
Diesel Mode during a Pretrip Test if these features are enabled and the
auto-switch conditions occur.

Conditions where Pretrip Tests are Not Allowed

• If any Shutdown Alarms are present. Pretrip tests are allowed with some
Check and Log Alarms.

TK 56704-1-OP-EN

• If the unit is in Sleep Mode.

• If the unit is in Service Test Mode, Interface Board Test Mode, or
Evacuation Mode.

Pretrip Test Sequence

Pretrip tests proceed in the order shown below. A Full Pretrip Test includes
all tests. A Running Pretrip Test is started with the engine or electric motor
running and does not include the Amp Checks or Engine Start Check.

• Amp Checks - Each electrical control component is energized and the
current drawn is confirmed as within specification.

• Engine Start - The engine will start automatically.

• Defrost - If the coil temperature is below 45°F (7°C), a defrost cycle is
initiated.

• RPM Check - The engine RPM in high and low speed is checked during
the Cool Check.

• Cool Check - The ability of the unit to cool in low speed is checked.

• Heat Check - The ability of the unit to heat in low speed is checked.

• Report Test Results - The test results are reported as PASS, CHECK, or
FAIL when the Pretrip Test is completed. If test results are CHECK or FAIL,
alarm codes will exist to direct the technician to the source of the
problem.

Pretrip Test Considerations

When performing a Pretrip Test, the following issues should be considered:

• If running a Pretrip Test on a truck loaded with dry cargo, verify proper
airflow can occur around the load. If the load restricts airflow, false test
results may occur. Also, SR-3 units have high refrigeration capacity
which results in rapid temperature changes. Sensitive dry cargo may be
damaged as a result.

• If running a Pretrip Test on a truck that has just been washed down, the
extremely high humidity inside the truck may result in false test results.

• If running a Pretrip Test on a truck loaded with sensitive cargo, monitor
the load temperature during the test as normal temperature control is
suspended during a Pretrip Test.

• Always perform Pretrip Tests with the truck cargo doors closed to
prevent false test failures.

Performing a Pretrip Test

If a Pretrip Test is initiated with the engine shut down, a Full Pretrip Test will
be performed. If a Pretrip Test is initiated with the engine or electric motor
running, a Running Pretrip Test is performed.

• Before initiating a Pretrip Test, clear all alarm codes.

• To stop a Pretrip Test at any time, turn the unit off. Alarm Code 28 Pretrip
Abort will be set. Other alarms may also be set depending upon test in
progress when the test was terminated.

Pretrip Tests are initiated using the Pretrip Menu. From the Standard

IImmppoorrttaanntt:: Make sure cargo is pre-cooled to the proper temperature before

loading. The Thermo King unit is designed to maintain
temperature, not cool an above-temperature load.

1. Inspect unit condenser grille openings to ensure they are free of debris.

2.

Inspect evaporator defrost drains to ensure they are not plugged or kinked.

3.

Confirm there is sufficient fuel in tank to operate unit for time required for deliveries.

4. Maintain a minimum of 1219 mm (48 in.) between evaporator air outlets and wall or
bulkhead.

5. Inspect cargo box compartment inside and out for:

• Inspect condition of door seals. They must seal tightly with no air leakage.

• Damaged walls, missing insulation or blocked floor channels.

• Inspect bulkheads (if applicable) for a air tight fit at ceiling, walls, and floor.

6. Using the HMI Controller, turn the unit on to pre-cool cargo compartment:

• Adjust setpoint to desired cargo temperature and allow unit to run a minimum of

30 to 60 minutes (longer if possible) before loading cargo.

Important: As product is being loaded, make sure evaporator air inlets and outlets are not

90

blocked. Maximum air circulation is necessary to properly maintain the
temperature of the entire load.

TK 56704-1-OP-EN

LLooaaddiinngg aanndd EEnnrroouuttee IInnssppeeccttiioonnss

Inspecting the Load

Never assume that the product has been loaded properly. Watch for and
perform the following tasks. It takes only a few minutes and could save you
or your employer considerable time and money later on.

1. Turn the unit off before opening the cargo box doors to maintain efficient
operation. Opening the doors while the unit is running allows warm air to
enter the cargo box.

NNoottee:: The unit can be run with the doors open if the truck is backed into a

refrigerated warehouse with tight loading dock door seals.

2. Perform a final check of the load temperature. If the load is too hot or too
cold, make a final notation on the manifest.

3. While inspecting to see that the cargo is loaded properly, make sure the
evaporator air inlets and outlets are not blocked.

4. Close or supervise the closing of the cargo compartment doors. Make
sure they are securely locked.

5. Check to make sure the unit setpoint is set at the desired temperature as
listed on the manifest.

6. If the unit was stopped, restart using the appropriate starting procedure
outlined in this manual.

7. Repeat the after-start inspection.

8. Defrost the unit 30 minutes after loading by starting a manual defrost
cycle.

Enroute Inspections

NNoottee:: Enroute inspections are recommended every four hours for the

prevention of damage to the cargo.

1. Note the setpoint to make certain no one has altered the setting since
picking up the load.

2. Note the return air temperature reading. It should be within the desired
temperature range. If the return air temperature reading is not within the
desired temperature range, it indicates one of the following:

a. The unit has not had sufficient time to pull down the temperature.

Refer to log, if possible, for history of load (for example, above
temperature load, properly pre-cooled cargo compartment, length of
time on road).

b. The unit is in defrost or has just completed defrost.

TK 56704-1-OP-EN

91

LLooaaddiinngg aanndd EEnnrroouuttee IInnssppeeccttiioonnss

NNoottee:: You can cancel defrost by turning the unit off, then restarting the

unit.

c. The evaporator is plugged with frost. Initiate a manual defrost cycle.

The defrost cycle will be automatically terminated.

d. Improper air circulation within the cargo compartment. Inspect the

cargo compartment (if possible) to determine if the evaporator fans
are working and properly circulating the air. Poor air circulation can
be due to improper loading of the cargo or shifting of the load, or the
fan belt slipping

e. The unit did not start automatically. If the unit cranked without

starting, determine and correct the cause for not starting.

f. The unit may have a low refrigerant charge. If liquid is not showing in

the unit receiver tank sight glass, the refrigerant charge may be low.
Adding refrigerant or repairing the refrigeration system requires a
competent mechanic. Refer such problems to the nearest Thermo
King dealer or authorized Service Center, or call the Thermo King
Cold Line telephone number shown on the inside back cover of this
manual for referral.

NNoottee:: If the temperature in the compartment is not within the desired

temperature range, repeat the Enroute Inspection every 30
minutes until the compartment temperature comes within the
desired temperature range.

IImmppoorrttaanntt:: Stop the unit if the compartment temperature remains

outside the desired temperature range from the setpoint on
two consecutive 30 minute inspections. Contact the nearest
Thermo King Service Center or your company office
immediately. Take all necessary steps to protect and
maintain proper load temperature.

3. Initiate a Manual Defrost cycle after each Enroute Inspection.

Unit Maintenance

A regular inspection and maintenance program will help to keep your unit in
top operating condition. While pre-trip inspections can be performed by the
operator (e.g., checking oil and coolant levels), all major and minor service
requirements should be handled by a Thermo King dealer for four very
important reasons:

• They are equipped with the factory recommended tools to perform all
service functions

• They have factory trained and certified technicians

• They have genuine Thermo King replacement parts

• The warranty on your new unit is valid only when the repair and
replacement of component parts is performed by an authorized Thermo
King dealer

After the first week of operation:

• Retighten unit mounting bolts

• Check belt tension

• Check coolant level

• Check engine oil level

• Check refrigerant level

• Check refrigerant oil level

The following general maintenance inspection schedule is provided to assist
in monitoring that maintenance.
