INGESTION
Do not induce vomiting. Contact local poison
control centre or physician immediately.
REFRIGERANT INFORMATION
Always observe caution when working with
refrigerants and in areas where they are being
used.
Fluorocarbon refrigerants evaporate rapidly,
freezing anything that they come in contact
with if accidentally released to the atmosphere
from their liquid state.
Refrigerants may produce toxic gases which, in
the presence of an open flame or electrical
short, can become severe respiratory irritants
which can be fatal.
Refrigerants displace air and can cause oxygen
depletion which could result in death by
suffocation. Observe caution at all times when
working with or around refrigerant, or air
conditioning systems which contain refrigerant,
especially in enclosed or confined areas.
RECOVER REFRIGERANT
At Thermo King we recognize the need to
preserve the environment and limit the
potential harm to the ozone layer that can
result from allowing refrigerant to escape into
the atmosphere. We strictly adhere to a policy
that promotes the recovery and limits the loss
of refrigerant into the atmosphere.

FIRST AID AND SAFETY
SAFETY PRECAUTIONS
Thermo King recommends all services be
performed by a Thermo King dealer. However,
there are several general safety practices which
you should be aware of:
1. Always wear 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.
2. Never operate the unit with the compressor
discharge valve closed.
3. Always keep your hands and loose clothing
clear of fans and belts when unit is running
or when opening or closing compressor
service valves.
4. Always use extreme caution if you ever have
occasion to drill holes in your unit. This
could weaken structural components.
Drilling into electrical wiring or refrigerant
lines could cause a fire.
5. All service work on evaporator or condenser
coils be completed by a certified Thermo
King technician. If you ever do have
occasion to be working around the coils, use
extreme caution as exposed coil fins could
cause painful lacerations.
AUTO START/STOP OPERATION
This unit may start up at any time without prior
warning.
CYCLE-SENTRY
If your unit is equipped for CYCLE-SENTRY
operation, the unit may start automatically at
any time when the unit is turned on and the
CYCLE-SENTRY is selected.
ELECTRIC STANDBY
On Model 50 units, the unit may start
automatically at any time when the unit is
switched on, connected to live electric power
and/or the Electric operation is selected.
Be sure to switch the unit off before opening
the doors or inspecting any part of the unit.
ELECTRICAL HAZARD
Units with electric operation or electric standby
present a potential electrical hazard. Always
disconnect the high voltage power cable before
working on the 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 medical attention.
WARNING!
Electric welding generates high amperage
currents which can damage electrical and
electronic components. To minimize
damage, prior to any welding operation on
the vehicle, the microprocessor and unit
battery must be electrically disconnected
from the vehicle. Switch the Microprocessor
On/Off switch to Off. Remove the negative
battery cable. Remove all connectors from
the rear of the microprocessor. Close the
control box. Connect the welder ground
cable as close as possible to the area being
welded. When welding is completed,
remove the welder ground cable. Reconnect
the cables to the rear of the
microprocessor. Reattach the negative
battery cable. Switch the microprocessor
On/Off switch to On. Reset all alarms and
codes to previous settings. Run a full
Pretrip. A detailed procedure may be found

document.
CYCLE-SENTRY START/STOP
CONTROLS
The CYCLE-SENTRY system automatically
starts up the unit when heating or cooling is
required and shuts it off when the cargo box
temperature reaches the controller setpoint.
The CYCLE-SENTRY system also maintains
engine temperature by restarting the unit if the
engine block temperature drops below -1°C. It
runs until the controller demand is satisfied and
the engine block temperature reaches 32°C.
CYCLE-SENTRY is designed for use only
with products which do not require tight
temperature control or continuous airflow, such
as all deep frozen products and non-perishable
non-frozen products.
The start/stop nature of CYCLE-SENTRY does
not satisfy the temperature control or airflow
requirements for perishable or temperature
sensitive products. Thermo King therefore does
NOT recommend the use of CYCLE-SENTRY
control for these products.
DEFROST
As the unit is operated to cool the trailer, frost
will gradually build up on the evaporator coils.
Periodically this frost must be melted to
prevent loss of cooling and airflow.
MODULATION
Systems equipped with modulation can provide
precise temperature control of fresh products.
This can reduce product dehydration, increase
product shelf life and protect fresh products
from freeze damage.
On Key Turns the unit on.
(hold button 1 second)
Off Key Turns the unit off.
Defrost Key Initiates a Manual
Defrost
Mode Key Switches the unit
between the CYCLE-SENTRY
and Continuous Run modes.
Soft Keys The four soft keys are
multi-purpose keys. Their
function changes depending on
the operation being performed. If
a soft key is active, it’s function
will be shown in the display
directly above the key.

CARE AND MAINTENANCE
CARE AND MAINTENANCE
PRE-TRIP INSPECTION
Pre-trip inspections are essential to minimize
operating problems and breakdowns, and must
be performed before every trip involving
refrigerated cargo.
1. Diesel Fuel
Must be sufficient diesel fuel to guarantee
engine operation to the next check point.
2. Engine Oil
Should be at the FULL mark. Never overfill.
3. Coolant
The indicator should be in the FULL (white)
range. If the coolant level is in the ADD (red)
range, add coolant to the expansion tank.
Coolant should be a 50/50 mixture of ethylene
glycol and water to provide protection to
-34°C.
Note: Please refer “Specifications” Chapter
later in this manual, where it is clearly states
which coolant types are allowed to be used
in this unit.
4. Battery
The terminals must be tight and free of all
corrosion. Electrolyte should be at full mark.
Note: To ensure battery remains in optimum
condition during periods when the unit is not
being used, run unit for at least 10-15
minutes once every 2 weeks.
5. Belts
The belts must be in good condition.
Tensioning is automatic. Do not attempt to
adjust.
6. Electrical
Ensure all electrical connections are securely
fastened. Wires and terminals should be free of
corrosion, cracks or moisture.
7. Structural
Visually inspect the unit for leaks, loose or
broken parts and other damage.
8. Gasket
The unit mounting gasket should be tightly
compressed and in good condition.
9. Coils
Ensure condenser and evaporator coils are
clean and free of debris.
• Washing with clean water should be
sufficient.
• The use of cleaning agents or detergents is
strongly discouraged due to the possibility of
degradation of the construction.
• If using a power washer, the nozzle pressure
should not exceed 600 psi (41 bar). For the
best results, spray the coil perpendicular to
the face of the coil. The spray nozzle should
be kept between 1 inch and 3 inches (25 to
75 millimetres) from the coil surface.
• If necessary to use a chemical cleaner or
detergent use a cleaner that does not contain
any hydrofluoric acids and is between 7 and
8 on the pH scale. Ensure dilution
instructions provided by the detergent
supplier are followed. In case of doubt about
the compatibility of the detergent with the
type of materials listed above, always ask the
supplier a written confirmation of the
compatibility.
• Should a chemical cleaner be required, it is
MANDATORY that all components are
thoroughly rinsed with water even if the
instructions of the cleaner specify that it is a
“no rinse” cleaner.
Warning: Failure to comply with above
mentioned guidelines will lead to a
shortened life of the equipment to an
indeterminable degree and also may void
your warranty.
Note: The repeated transportation of meat
and fish waste can cause extensive
corrosion to the evaporator coils and
evaporator section tubing over time due to
ammonia formation and can reduce the
lifespan of the coils. Appropriate additional
measures should be taken to protect the
CAUTION!
Do not remove the expansion tank cap
while the coolant is hot.

15
CARE AND MAINTENANCE
coils against the aggressive corrosion that
can result from transportation of such
products.
10. Cargo Box
Inspect the interior and exterior of the trailer for
damage. Any damage to the walls or insulation
must be repaired.
Note: On trailers equipped with units
qualified for pharmaceutical applications -
under ThermoKing protocol inspect the
integrity of the air chute.
11. Damper Door
The damper door in the evaporator air outlet
must move freely with no sticking or binding.
12. Defrost Drains
Check the defrost drain hoses and fittings to
ensure they are open.
13. Trailer Doors
Ensure doors and weather seals are in good
condition, doors latch securely and weather
seals fit tightly.
14. Remote Evaporators (SLXi Spectrum
and SLXi Spectrum Whisper Pro)
• Visually inspect Evaporator(s) for damaged,
loose, or broken parts.
• Check also for refrigerant leaks.
• Check Defrost initiation and termination
(including defrost timer) by activating/
initiating a manual defrost.
15. HSLO Module
(SLXi-300 Whisper Pro and SLXi Spectrum
Whisper Pro Units Only)
• Check that the module is turned on and
communicating.
• It’s a good idea to check at some stage
throughout your journey if the SR-3 unit
automatically switches to “High Speed Lock
Out” in an area designated for this - i.e. PIEK
assigned Zone.
LOADING
GENERAL INFORMATION
1. Inspect the trailer for proper insulation.
2. Ensure all door seals are tightly sealed with
no air leakage.
3. Inspect the trailer inside and out for damaged
or loose doors or skin.
4. On the inside, look for damaged walls or
floor, air ducts and clogged defrost drain
tubes.
5. Pre-cool the trailer as to desired setpoint.
6. Ensure loads are at correct carrying
temperature when you pick them up. Note
any variance.
7. Supervise loading of the product to assure
sufficient air space around and through the
load so as not to restrict air flow.
INSPECTING THE LOAD
Always inspect load prior to departure.
1. Ensure unit is off before opening the trailer
doors. Otherwise refrigerated air is expelled
hot air drawn in. The unit may be run with
the doors open if the trailer is properly
backed into a refrigerated warehouse.
2. Perform final external and internal load
temperature checks. Note any irregularities
on the manifest.
3. Ensure cargo is not blocking the evaporator
inlets and outlets and that ample circulation
space has been provided around the load.
4. Ensure trailer doors are securely locked.
5. Ensure controller setpoint is at the desired
temperature.
6. If the unit was stopped, restart using the
starting procedures outlined in this manual.
7. Repeat the After Start Inspection.
8. Defrost the unit one half-hour after loading
by selecting the Manual Defrost. The Defrost
cycle terminates automatically.

16
CARE AND MAINTENANCE
ENROUTE INSPECTIONS
1. Carry out an inspection every four hours of operation.
2. Note controller setpoint to ensure setting is unaltered since picking up
the load.
3. Note the return air temperature, it should be +/- 4°C of the controller
setpoint.
If the temperature reading is not +/- 4°C of the controller setpoint,
keep the unit running for 15 minutes and re-check the temperature.
Wait 15 minutes more and if the temperature is still out of range,
contact a Thermo King dealer for service.
4. We recommend you record the return air temperature reading each
time you check the unit. This is important information if you need
service later on.
5. Notes:
If cargo temperature is too high it could indicate:
• Evaporator is plugged with frost in which case standard defrosting
procedure is needed or there is improper air circulation within the
cargo area.
Inspect the unit to determine if the evaporator fan is working and
circulating the usual amount of air. Poor circulation could be caused
by:
– Fan belt slipping or damaged. (Have the fan belt checked by a
qualified mechanic.)
– Defrost damper Door damaged and stuck in closed position.
– Improper loading of product in trailer or load shifting in transit so
that there are restricted air passages around and through the load.
– Unit may have a low refrigerant charge. If you cannot see a liquid
level in receiver tank sight glass with the unit running in COOL, it is
an indication that the charge may be low.
It is advisable that any of the above mentioned problems found during
your enroute inspection be referred to the nearest authorized Thermo
King dealer as quickly as possible. Check your service directory for
phone number and location.
INSPECTION AND SERVICE SCHEDULES
To ensure that your Thermo King unit operates reliably and economically
over its full life, and to avoid limiting its warranty cover, the appropriate
inspection and service schedule must be followed.
WEEKLY CHECKS
In order to keep your unit in good working order - the following checks
must be carried out by the operator on a weekly basis:
1. Check fuel supply.
2. Coolant/engine oil level - Check and adjust if necessary.
3. Perform automatic Pre-Trip.
4. Listen for unusual noises, vibrations etc.
5. Visually inspect belt
6. Visually inspect unit for fluid leaks (fuel, coolant, oil and refrigerant).
7. Visually inspect unit for damaged, loose or broken parts (includes air
ducts and bulkheads if so equipped).
