Safety Precautions
Thermo King recommends that servicing be done only by a
Thermo King dealer. However, you should be aware of several
safety practices. This chapter gives basic safety precautions for
working with Thermo King units and describes the safety
stickers on your unit that you should be familiar with.
General Safety Practices
DANGER: NEVER operate the unit with the
compressor discharge valve closed. Doing so could
cause the compressor to explode, causing death or
serious injury.
WARNING: Always wear goggles or safety glasses
when working with or around the refrigeration system
or battery. Refrigerant or battery acid can cause
permanent damage if it comes in contact with your
eyes.
WARNING: Keep hands and loose clothing clear of
fans and belts at all times when the unit is operating
or when opening or closing compressor service
valves.
WARNING: Exposed coil fins can cause painful
lacerations. Service work on the evaporator or
condenser coils should be done by a certified Thermo
King technician.
WARNING: Do not apply heat to a closed cooling
system. Before applying heat to a cooling system,
drain it. Then flush it with water and drain the water.
Antifreeze contains water and ethylene glycol. The
ethylene glycol is flammable and can ignite if the
antifreeze is heated enough to boil off the water.

Safety Precautions
CAUTION: Use extreme caution when drilling holes
in the unit. Drilling into electrical wiring or
refrigerant lines could cause a fire. Do not drill into
structural components.
Automatic Start/Stop Operation
This unit is capable of automatic operation and could start at
any time without warning.
WARNING: CYCLE-SENTRY Operation. The unit
can start at any time when the unit On/Off switch is
in the on position and the unit is operating in
CYCLE-SENTRY.
WARNING: Turn the unit On/Off switch to the Off
position before inspecting any part of the unit.
Electrical Hazard
CAUTION: Turn off the high voltage power supply
and disconnect the electric cable before working on
the unit. Units with electric standby present a
potential electrical hazard.
Refrigerant
Although fluorocarbon refrigerants are classified as safe, use
caution when working with refrigerants or in areas where they
are being used.
DANGER: Fluorocarbon refrigerants can 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 Description
Diesel Engine
ELC (Extended Life Coolant)
The unit uses a quiet running TK486V (Tier 2), which is a
4-cylinder, water cooled, direct injection diesel engine. The
engine is coupled directly to the compressor. Belts transmit
power to the unit fans, alternator and water pump.
ELC (Extended Life Coolant) is standard equipment. The
maintenance interval for ELC is five years or 12,000 hours. A
nameplate on the coolant expansion tank identifies units with
ELC (see “Safety Decals and Locations”). The new engine
coolant, Chevron Extended Life Coolant, is RED in color
instead of the previous GREEN or BLUE-GREEN colored
conventional coolants.
CAUTION: Do not add “GREEN” or
“BLUE-GREEN” conventional coolant to cooling
systems using “RED” Extended Life Coolant, except
in an emergency. If conventional coolant is added to
Extended Life Coolant, the coolant must be changed
after 2 years instead of 5 years.
NOTE: The use of 50/50% pre-mixed ELC is recommended
to assure that de-ionized water is being used. If 100% full
strength concentrate is used, de-ionized or distilled water is
recommended instead of tap water to insure the integrity of
the cooling system is maintained.

CYCLE-SENTRY Start-Stop Controls
Defrost
The CYCLE-SENTRY Start-Stop fuel saving system provides
optimum operating economy.
Frost gradually builds-up on evaporator coils as a result of
normal operation. The unit uses hot refrigerant to defrost the
evaporator coils. Hot refrigerant gas passes through the
evaporator coil and melts the frost. The water flows through
collection drain tubes onto the ground. The methods of defrost
initiation are Manual and Automatic.
CYCLE-SENTRY automatically starts the unit on
microprocessor demand, and shuts down the unit when all
demands are satisfied.
The system automatically monitors and maintains
compartment temperatures, the engine block temperature and
battery charge levels at a point where quick, easy starts are
possible.
WARNING: Set the unit ON/OFF switch to OFF
before opening doors or inspecting any part of the
unit. With the unit ON/OFF switch in the ON position,
the unit may start at any time without warning.
Automatic Defrost: The controller is programmed to
automatically initiate timed or demand defrost cycles. Defrost
intervals are set at the factory at 2, 4 6, 8, 10, or 12 hours. The
unit can enter a demand defrost cycle as often as every 30
minutes if required.
Manual Defrost: The operator manually initiates a defrost
cycle.
NOTE: The unit will not perform a Manual Defrost cycle
unless the ON/OFF switch is set to ON, the unit is running in
Continuous or CYCLE-SENTRY mode, (or shut down in
CYCLE-SENTRY Null mode), and the coil temperature is
below 45 F (7.2 C).

Unit Description
Receiver Tank Sight Glass: This sight glass indicates the
level of refrigerant in the receiver tank.
Operate the unit in high speed cool for approximately 15
minutes to stabilize operating conditions and temperature
before attempting to check the refrigerant.
High Pressure Relief Valve: This valve is designed to
relieve excessive pressure in the refrigeration system. It is
located on the receiver tank. If the high pressure relief valve
opens, much of the refrigerant will be lost. Take the unit to a
Thermo King dealer if this occurs.
NOTE: If the ball floats, there is sufficient refrigerant in the
unit for that load at that particular trailer temperature. This
test does not determine if the unit contains a full charge or an
overcharge of refrigerant.
Low Oil Level Switch: The low oil level switch closes if the
oil drops below an acceptable level. If it stays closed for a
specified time, the microprocessor shuts the unit down and
records Alarm Code 66.
Unit Protection Devices
Low Oil Pressure Switch: The low oil pressure switch
closes if the oil pressure drops below an acceptable level. If it
stays closed for a specified time, the microprocessor shuts the
unit down and records alarm code 19.
Fuse Link (Current Limiter): The fuse link is located in the
positive battery cable. The fuse link protects the electric
system from a short. If the fuse link burns out, replace it by
replacing the positive battery cable.
Preheat Buzzer: The preheat buzzer sounds when the
controller energizes the preheat relay. This warns anyone near
the unit that the controller is about to start the engine.
High Pressure Cutout Switch: The high pressure cutout
switch (HPCO) is located on the compressor discharge
manifold. If the compressor discharge pressure becomes
excessive, the switch opens the circuit to the run relay to stop
the unit. The microprocessor will record Alarm Code 10.

Manual Pretrip Inspection
(Before Starting the Unit)
Pretrip 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 involving refrigerated cargo.
NOTE: Pretrip inspections are not intended to take the place
of regular maintenance inspections.
Fuel: Make sure the diesel fuel supply is adequate to
guarantee engine operation to the next check point. Allow for
maximum fuel consumption of one gallon per hour of engine
operation.
Engine Oil: Check the engine oil level. It should be at the
Full mark when the dipstick is threaded all the way into the oil
pan. Do not overfill.
CAUTION: Turn the engine off before checking the
engine oil level.
Engine Coolant: Check the engine coolant level. The engine
coolant must have antifreeze protection to –30 F (–34 C).
Maintain a minumum of 50% Ethylene Glycol based coolant
and 50% water mixture. Do not mix solution any stronger than
68% Ethylene Glycol based coolant and 32% water for use in
extreme temperatures.
WARNING: Do not remove the expansion tank cap
while the coolant is hot.
The engine is designed to operate on Ethylene Glycol based
coolant. This is the only recommended coolant type. Failure to
use the proper antifreeze mixture could cause plugging or
engine overheating. Do not mix brands, use water alone or mix
rust inhibitors.
Do not overfill the coolant.

Manual Pretrip Inspection (Before Starting the Unit)
Keep the radiator clean and clear of debris by gently spraying
with water.
Damper: Make sure the damper in the evaporator air outlets
move freely, with no sticking or binding.
NOTE: Used Ethylene Glycol based coolant is a regulated
substance requiring proper disposal. Check for local disposal
regulations. Do not store in open containers. Keep away from
children and animals.
Coils: Make sure the condenser and evaporator coils are clean
and free of debris.
CAUTION: If air is suspected to be trapped in the
system, it must be bled out. If the engine runs with air
trapped in the block, the engine may be damaged.
Battery: Make sure the battery terminals are tight and free of
corrosion. Electrolyte should be at the Full mark.
Belts: Make sure belts are in good condition and adjusted to
the proper tension. For more information about belt tension,
see the Specifications chapter.
Cargo Box: Check the interior and exterior of the trailer for
damage. Any damage to the walls or insulation must be
repaired.
Defrost Drains: Check the defrost drain hoses and fittings to
make sure they are open.
Doors: Make sure that the doors and weather seals are in good
condition. The doors should latch securely and the weather
seals should fit tightly.
IMPORTANT: To prevent damage to the controller, always
push the controller access door firmly closed.
Electrical: Check the electrical connections to make sure they
are securely fastened. Wires and terminals should be free of
corrosion, cracks, and moisture.
Structural: Visually inspect the unit for leaks, loose or
broken parts, and other damage.

Alarm Types
Corrective Action
The three types of alarms are described below. They can occur
individually or with other alarms. More than one alarm can be
present at one time.
There are three levels of corrective action that can be taken
when an alarm condition occurs.
Stored Alarm: Indicates a condition exists that should be
investigated, but does not affect unit operation. The alarm icon
will appear for 30 seconds when the unit On/Off switch is
turned on, then it disappears.
Check Alarm: Notice to take corrective action before an
abnormal condition becomes severe. The alarm icon will
appear and remain on.
Shutdown Alarm: Indicates conditions that could damage
the unit. The unit will automatically shut down, the alarm icon
will appear, and the entire display will flash on and off.
OK To Run: An alarm condition exists but does not affect
unit operation. Corrective action can occur at a later date.
Check As Specified: An alarm condition exists that could
affect unit operation. Follow directions in the Corrective
Action column on the following chart.
Take Immediate Action: An alarm condition exists that
will damage the unit or load. Take immediate action to correct
the problem.
NOTE: The corrective actions listed above and on the
following chart are suggestions only. Always consult your
company for final decisions.
NOTE: Alarms that occurred during a unit pre-trip or self
check will be preceded by a dash (-). Refer to the Alarm Type
column on the following chart.
NOTE: Some alarms are self-clearing. These alarms will
clear automatically when the operating condition causing the
alarm returns to normal.

Alarm Codes
Alarm Code 84 (Restart Null)
Alarm Code 84 is a temporary abnormal condition resulting
from other alarms. The unit shuts down for approximately 15
minutes. The unit will restart after approximately 15 minutes,
or after the condition has reset, and in most cases the other
alarm(s) will have been cleared. If after 3 attempts, the
condition continues to occur, the alarm that caused the
shutdown will appear on the display and the unit will shut
down until the alarm is cleared. Code 84 will automatically
clear after the final attempt at restarting has occurred.
Alarm Code 85
(Forced Unit Operation)
Alarm Code 85 is also a temporary abnormal condition
resulting from other alarm(s). The unit goes into an abnormal
mode which allows the unit to continue to run without shutting
down, the unit may however run with reduced capacity. When
the alarm that caused 85 is no longer active, Alarm Code 85
will be reset.

Loading and Enroute Inspections
This chapter describes pre-loading, post loading, and enroute
inspection procedures. Thermo King refrigeration units are
designed to maintain the required product load temperature
during transit. Follow these recommended loading and enroute
procedures to help minimize temperature related problems.
4.
Verify that the setpoint temperature is correct for your
cargo. Pre-cool the trailer as required.
5.
Push the microprocessor controller access door firmly
closed after setting temperature setpoint
CAUTION: Push the controller access door firmly
closed after each use. Damage can occur in transit if
the door is not properly closed.
Pre-Loading Inspection
1.
Pre-cool products before loading. Note any variances on
the manifest.
2.
Inspect door seals and vent doors for condition and a tight
seal with no air leakage.
3.
Inspect the trailer inside and out. Look for:
•
Damaged or loose trailer skin and insulation
•
Damaged walls, air ducts, floor channels or “T”
flooring
•
Clogged defrost drain tubes
•
Blocked return air bulkhead
6.
Supervise product loading to ensure sufficient air space
around and through the load. Airflow around the cargo
must not be restricted.
NOTE: If the warehouse is not refrigerated, operate the
unit with doors closed until cargo is ready to be loaded.
Then turn off the unit, open cargo doors and load cargo.
When cargo is loaded, close trailer doors and restart the
unit.
The unit can be operated with the cargo box doors open
if the truck is backed into a refrigerated warehouse and
the dock door seals fit tightly around the trailer.

Jump Starting
If the battery in a unit is discharged or run down, the unit may
be jump started using jumper cables and another battery or
vehicle. Consider the following precautions and be careful
when jump starting a unit.
WARNING: A battery can be dangerous. A battery
contains a flammable gas that can ignite or
explode. A battery stores enough electricity to burn
you if it discharges quickly. A battery contains
battery acid that can burn you. Always wear
goggles or safety glasses and personal protective
equipment when working with a battery. If you get
battery acid on you, immediately flush it with water
and get medical attention.
CAUTION: Unhook the semi tractor from the
trailer before using the tractor to jump start the
unit on the trailer. The negative ground circuit is
complete when the tractor is hooked to the trailer.
This can cause dangerous sparks when the positive
connection is made at the battery.
IMPORTANT: Make sure to use a 12-volt battery to jump
start the unit. If you are using a vehicle, make sure it has a
12-volt battery with a negative ground system. Do not use a
“hot shot” booster device or a 24-volt source.
Read and understand the following procedure completely
before connecting any jumper cables. Use good jumper cables
made with #2 gauge (or larger) cables.
1.
Make sure the unit is turned off. If you are using a vehicle,
make sure its ignition is also turned off.
2.
Open the front doors on the unit. The battery is located to
the right of the engine.
3.
Check the discharged battery to make sure it is not
damaged or frozen. Do not jump start a damaged or frozen
battery. Check the vent caps to make sure they are tight.
