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!!
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 Syste 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

12 TK 56702-1-OP-EN
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.
NN TTIICCEE

EELLEECCTTRRIICCAALL SSHHOOCCKK
Take I EDIATE 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
SSaaffeettyy PPrreeccaauuttiioonnss

14 TK 56702-1-OP-EN
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
victim from power source, immediately check for signs of a pulse and
respiration. If no pulse is present, start Cardio Pulmonary Resuscitation
(CPR). If a pulse is present, respiration might be restored by using mouth-to-
mouth resuscitation. Call for emergency medical assistance.
AASSPPHHYYXXIIAATTIIOONN
ove victim to fresh air and use Cardio Pulmonary Resuscitation (CPR) or
mouth-to-mouth resuscitation to restore breathing, if necessary. Stay with
victim until emergency personnel arrive.
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.

portion protruding into the box. The unit uses Chlorine free R-404A
refrigerant.
The basic models provide the following:
SSttaannddaarrdd UUnniitt (( ooddeell 3300)):: Cooling and hot gas heating on engine
operation.
SSmmaarrttPPoowweerr™™ UUnniitt (( ooddeell 5500)):: Cooling and hot gas heating on engine
operation and electric standby operation. Electric evaporator heaters are
optional.
A three cylinder, EPA Tier 4, special clean and quiet diesel engine powers the
unit when in the truck is in route. SmartPower ( odel 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 H I
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-590, T-690, and T-890 is provided by the TK374F, a
three-cylinder, EPA Tier 4, special clean and quiet diesel engine rated at
13.27 continuous horsepower (9.9 kW) at 2200 RP and 14.61 continuous
horsepower (10.9 kW) at 2425 RP . A belt drive system transfers energy to
the compressor, unit fans, and alternator.
Engine power for the T-1090 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 RP . A belt drive system transfers energy to
the compressor, unit fans 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) Na eplate
RCS1161
IImmppoorrttaanntt:: nly AT 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 50/50% 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. The
engine must have antifreeze protection to -40°F/ -40°C. Check and add
coolant in the expansion tank as needed.
Clutch
The centrifugal clutch engages fully at 600 ± 100 RP on engine operation,
constantly turning the compressor, alternator, and fans at both high and low
speed. The clutch isolates the engine from the belt drive system during
electric standby operation on odel 50 units.
Reciprocating Co pressor
The T-590 and T-690 feature the X214, 2 cylinder reciprocating compressor
with 13.92 cu in (229 cc) displacement.
The T-890 and T-1090 feature the X430P, 4 cylinder reciprocating compressor
with 30.0 cu in (492 cc) displacement.
HMI Controller
The H I 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 Syste
The CYCLE-SENTRY Start/Stop fuel saving system provides optimum
operating economy.
