Introduction
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 on-the-road 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.

IMPORTANT: This manual is published for informational
purposes only and the information furnished herein should
not be considered as all-inclusive or meant to cover all
contingencies. If more information is required, consult your
Thermo King Service Directory for the location and
telephone number of the local dealer.
Safety Precautions
Thermo King recommends that all services be performed by a
Thermo King dealer. However, there are several general safety
practices which you should be aware of:
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 is best left to a certified Thermo King
technician.
CAUTION: Use extreme caution when drilling holes
in the unit. Drilling into electrical wiring or
refrigerant lines could cause a fire. Never drill into
structural components.
Automatic Start/Stop Operation
This unit is capable of automatic operation and may start at any
time without prior warning.
WARNING: The unit may start at any time when the
controller is turned on. The controller display lights
up when the controller is turned on.
WARNING: Units equipped with electric standby may
start at any time when the unit is connected to live
electric power and the controller is turned on.
WARNING: Be sure to press the OFF key to turn the
controller off before opening doors or inspecting any
part of the unit.
7
Safety Precautions
Battery Installation and Cable
Routing
WARNING: Improperly installed battery could
result in a fire or explosion! A Thermo King
approved battery must be installed and properly
secured to the battery tray.
WARNING: Improperly installed battery cables
could result in fire or explosion! Battery cables
must be installed, routed and secured properly to
prevent them from rubbing, chaffing or making
contact with hot, sharp or rotating components.
WARNING: Do not attach fuel lines or any
additional wiring harnesses to the battery cables as
this could cause an electrical fire!
CAUTION: Do not connect other manufacturer’s
equipment or accessories to the Thermo King unit.
This could result in severe damage to equipment
and void the warranty!
8
CAUTION: Set all unit electrical controls to the
OFF position before connecting battery cables to
the battery to prevent unit from starting
unexpectedly and causing personal injury.
CAUTION: Always wear protective clothing,
gloves and eye wear when handling and installing
batteries. Battery acid can cause serious burns
when exposed to eyes or skin. If battery acid
contacts skin or clothing, wash immediately with
soap and water. If acid enters your eye,
immediately flood it with running cold water for at
least twenty minutes and get medical attention
immediately.
CAUTION: Always cover battery terminals to
prevent them from making contact with metal
components during battery installation. Battery
terminals grounding against metal could cause the
battery to explode.
Safety Precautions
Electrical Hazard
CAUTION: Be sure to 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,
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.
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.

28
Unit Description
WARNING: Turn the unit off by pressing the OFF key
before opening doors or inspecting any part of the
unit. The unit can start at any time without warning if
it has been turned on by pressing the ON key.
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.
The defrost damper closes during defrost to prevent warm air
from entering the cargo area. The optional electric heater strips
are also energized in defrost during electric standby operation.
Defrost can be initiated at any time the evaporator coil
temperature is below 42 F (5.5 C).
There are two methods of defrost initiation:
SR-3 Microprocessor Controller: The Microprocessor
Controller is programmed to automatically initiate timed and
forced defrost cycles. The SR-3 uses temperature sensors to
determine if forced defrost is required.
Manual Defrost: Manual Defrost allows the operator to
initiate a defrost cycle by pressing the DEFROST key. See
“Initiating a Manual Defrost Cycle.”
DAS - Data Acquisition System
(Optional)
The DAS (Data Acquisition System) monitors and records the
temperatures of (up to) six additional sensors. The sensors are
independent from the microprocessor controller and are
normally located in the truck box to monitor load temperatures.
29
Unit Description
DAS data can be downloaded through a serial port to an IBM®
PC compatible computer. WinTrac™ 4.0 (or higher) software
is used to view and analyze the data. Brief reports can be
printed on a microprinter connected to the serial port.
CargoLink™ (Optional)
CargoLink™ is a wireless sensor system. The main
components are the coordinator module, interconnect harness,
antenna, and wireless sensors. The coordinator module
receives information from the wireless sensors through the
antenna, and communicates with the controller through the
interconnect harness. Currently, only wireless door switches
are available. Other wireless sensors will be available in the
future. Refer to TK 55151 the Truck and Trailer Edition
CargoLink Installation Manual for information about installing
the CargoLink system and sensors, and troubleshooting
problems with the system.
30
Electric Standby (Model 50 Units
Only)
The Electric Standby option allows the unit to be operated on
either the diesel engine or external electric power.
DANGER: High voltage AC power is present
whenever the unit is operating in the Electric 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.
Unit Description
Standard Model 50 Features
The following features are standard equipment on units
equipped with Electric Standby.
Automatic Diesel/Electric Selection: The unit will
automatically switch to electric operation when a power cord is
connected and the standby power is switched On.
Overload Relay: The overload relay is self-resetting.
Hot Gas Heat: Hot gas heat is utilized on all units.
Engine Compartment
Components
Coolant Expansion Tank: The coolant level and
temperature are monitored by the base controller. If the coolant
temperature becomes too high or the level becomes too low, an
alarm will occur.
The engine must have antifreeze protection to –30 F (–34 C).
Check and add coolant in the expansion tank as needed.
Automatic Phase Correction: The control system features
two motor contactors. This allows correct motor rotation
regardless of phase rotation on the incoming power.
CAUTION: Do not remove expansion tank cap
while the coolant is hot.
Optional Model 50 Features
CAUTION: Do not add Green or Blue-Green
coolants to cooling systems that use Red Extended
Life Coolants.
The following features are available as options on units
equipped with Electric Standby.
•
Electric Heater Strips
•
Auto Switching
Engine Oil Dipstick: Use the engine oil dipstick to check
the engine oil level.
31
Unit Description
Receiver Tank Sight Glass: The receiver tank sight glass
is used to assist in checking the amount of refrigerant in the
system.
Compressor Oil Sight Glass: The compressor oil sight
glass is used to check the relative level of compressor oil in the
compressor sump.
Unit Protection Devices
High Pressure Cutout Switch (HPCO): This normally
closed switch monitors the discharge pressure at the
compressor. It opens on high discharge pressure to shut the unit
down to prevent damage.
Suction Pressure Regulator (SPR): This component is a
mechanical control device used to limit the suction pressure to
the compressor. The valve controls suction pressure based on
the actual system pressure. (Scroll compressor units: The SPR
is not used if the unit is equipped with an ETV.)
Electronic Throttling Valve (ETV): (Scroll compressor
units only.) This component is an electromechanical control
device used to limit the suction pressure to the compressor. The
valve is controlled by the microprocessor controller.
32
Engine Oil Pressure Switch/Sensor: The engine oil
pressure switch/sensor is located on the filter head above the
bypass oil filter. Engine oil pressure should rise immediately
on starting. If engine oil pressure drops below 10 ± 2 psig (69 ±
14 kPa), the switch/sensor signals the microprocessor to stop
the engine.
Preheat Buzzer: The preheat buzzer sounds when the
CYCLE-SENTRYTM system energizes the glow plugs. This
should warn anyone near the unit that the CYCLE-SENTRYTM
system is about to start the diesel engine.
Coolant Temperature Sensor: This sensor provides an
engine coolant temperature input to the microprocessor. If the
engine coolant temperature is too high, the controller stops the
unit and records an alarm.
Electric Motor Overload Relay (Model 50): The
overload relay protects the electric standby motor. The
overload relay opens the circuit from the contactor to the
electric motor if the motor overloads for any reason and an
alarm will occur. The relay resets when the alarm code is
cleared.
Fuses: Sizes and functions are described in the Specifications
section of this manual.

Unit Operation
Initiating a Manual Defrost Cycle
Defrost cycles are usually initiated automatically based on time
or demand. Manual defrost may also be available. Defrost is
only available if the unit is running and the evaporator coil
temperature is less than 45 F (7 C). Other features such as door
switch settings may not allow manual defrost under some
conditions.
IMPORTANT: During the defrost cycle, the box temperature
will rise toward 50 F (10 C). This is normal and is caused by
the defrost cycle warming the evaporator coil. Since the
damper door is closed during the defrost cycle, this warm air
is not allowed to pass into the truck box.
To initiate a manual defrost cycle, press the DEFROST Key as
shown in Figure 34. If conditions allow, the unit will enter a
defrost cycle and the amber LED next to the DEFROST Key
will glow.
Figure 35: Box temperature will rise toward
50 F (10 C)
Terminating a Defrost Cycle

The defrost cycle terminates automatically when the coil
temperature is greater than or equal to 52 F (11 C) or the
maximum defrost timer expires. Alarm code 14, Defrost
Terminated by Time, will generate if the maximum defrost
time is exceeded. When the defrost cycle is completed the
amber LED next to the DEFROST Key will turn off. Defrost
can also be terminated by turning the unit off and back on.

Pretrip Test Considerations
When performing a Pretrip Test, the following issues should be
considered.
67
Unit Operation
•
Whenever possible, run the Pretrip Test with an empty
truck box.
Performing a Pretrip Test
•
If running a Pretrip Test on a truck loaded with dry cargo,
insure that proper airflow can occur around the load. If the
load restricts airflow, false test results may occur. Also,
units have high refrigeration capacity which results in
rapid temperature change. Sensitive dry cargo may be
damaged as a result.
Starting a Pretrip Test
•
If running a Pretrip Test on a truck that has just been
washed down, the extremely high humidity inside the
truck box 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 pre-trip
operation.
•
Always perform Pretrip Tests with the cargo doors closed
to prevent false test results.
The Full Pretrip Test must be started with the unit not running.
Turn the unit on and clear all alarm codes. Turn the unit off.
Turn the unit on and wait for the unit running time hourmeters
to be shown on the display. When the unit running time
hourmeters are shown on the display, press and hold the
PRETRIP Key for 5 seconds.
Figure 41: Pretrip Test
•
68
A flashing Pretrip LED indicates that the Pretrip Test is
being initialized. When the Pretrip Test starts, the Pretrip
LED will glow steady amber. The display will show the
Standard Display.
Unit Operation
•

Electric Standby Operation
SmartPower (Model 50) units are equipped with Electric
Standby. This feature allows the unit to operate on electric
power as well as be powered by the standard diesel engine.
During Electric Standby operation, power to the unit is
supplied by an electric motor connected to a high voltage
power source. Check the unit for proper power source ratings.
Electric Power Receptacle
The electric power receptacle is used to connect the unit to an
appropriate electric power source for electric standby
operation. Turn the unit OFF before connecting or
disconnecting the power cord.
WARNING: Units equipped with electric standby can
start at any time when the unit is connected to live
electric power and the controller is turned on.
CAUTION: Always turn the electric power supply off
when handling, connecting, or disconnecting high
voltage power cords.
Figure 46: Model 50 Power Receptacle Box
NOTE: The Model 50 control system automatically
determines if diesel or electric power is desired.
See “Starting the Electric Motor” in the Unit Operation chapter
of this manual.
72
Loading and Enroute Inspections
Thermo King refrigeration units are designed to maintain the
required temperature for the product being carried during its
time in transit. Because of the unit’s unique design, special care
is required during loading to prevent cargo spoilage.
4.
Pre-Loading Inspection
1.
Inspect all door seals, including vent doors, for condition
and a tight seal with no air leakage.
2.
Inspect the cargo compartment inside and out for damaged
or loose skin and insulation.
3.
Inspect the inside of the cargo compartment for damaged
walls, air ducts, floor channels or “T” flooring, clogged
defrost drain tubes, and clogged or damaged floor
channels which could block the air return, creating
isolated areas in the load that are warmer than the desired
temperature.
Pre-cool the cargo compartment. Adjust the setpoint to the
desired cargo temperature and allow the unit to run a
minimum of 30 to 60 minutes (longer if possible) before
loading. Check to be certain the setpoint temperature is
correct for the cargo.
Pre-cooling before loading will remove residual heat and
moisture from the cargo compartment and prepare it to
receive the refrigerated load. Pre-cooling also provides a
good test of the refrigeration system.
5.
Make sure products are pre-cooled to the proper
temperature before loading. Any variance should be noted
on the manifest.
6.
Supervise product loading to make sure that there is
sufficient air space around and through the load so air flow
is not restricted.
73
Loading and Enroute Inspections
Inspecting the Load
3.
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.
While inspecting to see that the cargo is loaded properly,
make sure the evaporator inlets and outlets are not
blocked.
4.
Close or supervise the closing of the cargo compartment
doors. Make sure they are securely locked.
1.
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.
Make sure the unit is off before opening the cargo
compartment doors. During operation, the unit blows out
refrigerated air, and draws in outside air.
NOTE: The unit can be run with the doors open if the
truck is backed into a refrigerated warehouse with tight
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.
CAUTION: Make sure cargo is pre-cooled to the
proper temperature before loading. The unit is
designed to maintain temperature, not cool an
above-temperature load.
74
Loading and Enroute Inspections
Enroute Inspections
NOTE: 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.
b.
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).
The unit is in defrost or has just completed defrost.
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.
WARNING: The unit may START automatically AT
ANY TIME while it is turned ON. Make sure to turn
the unit OFF before opening unit doors or inspecting
any part of the unit.
e.
The unit did not start automatically. If the unit
cranked without starting, determine and correct the
cause for not starting.
NOTE: You can cancel defrost by turning the unit off,
then restarting the unit.
75
Loading and Enroute Inspections
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.
NOTE: 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.
76
CAUTION: 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.

consisting of chlorine, fluorine and carbon. Example: R12. In
many countries it is illegal to release this type of refrigerant to
the atmosphere because chlorine damages the earth’s
atmosphere. CFC refrigerants are not used in modern Thermo
King units.
circuit breaker: A thermal device that automatically
interrupts an electrical circuit when the current in the circuit
exceeds the predetermined amperage rating of the breaker. See
amp.
coil: A cooling or heating element made of pipe or tube,
formed into a helical or serpentine shape, that may be equipped
with thin metal fins to aid heat transfer.
cold curtains: Flexible vinyl curtains used to reduce air
exchange between the refrigerated compartment and the
outside during door openings.
compound gauge: A gauge calibrated in psig (or kPa) to
measure pressure, and in inches of mercury (Kg/cm2) to
measure vacuum.
compressor: The refrigeration component that compresses
refrigerant vapor and creates refrigerant flow.
condenser: An arrangement of tubing in which the
vaporized and compressed refrigerant is liquefied as heat is
removed.
cycles per second: See Hertz.
damper door: A door on the evaporator section that closes
during defrost to prevent hot air from entering the refrigerated
cargo compartment.
data logger: An electronic device that monitors and stores
unit operating and temperature data for later review. Examples:
DMS, DAS, DRS and AccuTrac.
defrost: The removal of accumulated ice from an evaporator
coil. Periodic defrost is necessary when the evaporator coil is
operating below freezing. Defrost is required more frequently
when the air passing through the evaporator has a high
moisture content.
defrost termination switch: A component that terminates
defrost operation at a specific temperature.
defrost timer: A solid state module that initiates defrost at
selected intervals. Also establishes a maximum defrost
duration if normal circuits malfunction.

Glossary
dehydrator: A device used to remove moisture from
refrigerant. Also called a drier.
discharge air temperature: The temperature of air leaving
the evaporator.
drier: See dehydrator.
ERC: Extended Remote Unit Control. (Door switches) An
option on Thermo King multi-temperature units to improve
temperature control when doors are opened during delivery.
When a compartment door is opened, the refrigeration unit for
that compartment may be forced to NULL, defrost, or some
other mode. Opening a compartment door may also affect the
operating mode of other compartments. ERC systems are
connected in a variety of ways to meet customer needs.
ETV (Electronic Throttling Valve) : A device used with a
microprocessor to precisely control the refrigeration system.
evaporator: The part of the refrigeration system that absorbs
heat during the cooling cycle.
F: See Fahrenheit.
Fahrenheit: A unit of temperature measurement used in the
United States. Abbreviated “F.”
98
freeze up: 1) Failure of a refrigeration system to operate
normally due to moisture in the refrigerant and the formation
of ice at the expansion valve. The expansion valve may be
frozen shut or open, causing improper unit operation in either
case. 2) The formation of a solid ice mass over the evaporator
coil reducing air flow.
fuse: An electrical safety device (typically a cartridge)
inserted into an electrical circuit. It contains material that will
melt or break when the current is increased beyond a specific
value. When this occurs, the circuit is opened and electrical
current flow is stopped.
fusible link: An electrical safety device (typically a short
piece of wire) inserted into an electrical circuit. The wire melts
or breaks when the current is increased beyond a specific
value. When this occurs, the circuit is opened and electrical
current flow is stopped.
HCFC: Hydrochlorofluorocarbon. A chlorine-based
refrigerant containing hydrogen, chlorine, fluorine and carbon.
Example: R22. Because chlorine damages the earth’s
atmosphere, in many countries, it is illegal to release this type
of refrigerant to the atmosphere. HCFC refrigerants are not
used in modern Thermo King units.
Glossary
Hertz: A unit of frequency equal to one cycle per second.
Abbreviated “Hz.”
HFC: A refrigerant consisting of hydrogen, fluorine and
carbon. Examples: R134a and 404A. HFC refrigerants contain
no chlorine and are, therefore, considered “safe” for the
environment.
high pressure relief valve: A safety valve on the
refrigeration system that allows refrigerant to escape from the
system if pressure exceeds a predetermined value.
hp (horsepower): A unit of power equivalent to 746 watts
or 550 foot-pounds per second.
HPCO (High Pressure Cut Out Switch): A
pressure-operated switch that opens to stop unit operation
when discharge pressure reaches a predetermined maximum.
kPa: Kilopascals. A metric unit of pressure. 1 kPa = 0.01 bar =
0.145 psi.
load: 1) The product being refrigerated and transported.
2) The amount of heat being removed by the refrigeration
system. (For example, a compressor is under a heavy heat load
when expected to cool a very warm box.)
LPCO (Low Pressure Cut Out Switch): A
pressure-operated switch that opens to stop unit operation
when suction pressure reaches a predetermined minimum.
modulation: An optional system that reduces load (product)
dehydration and avoids “top freeze.”
movable bulkhead: A thick, insulated, portable wall-like
device used to compartmentalize a temperature-controlled
truck or trailer. See bulkhead.
Multi-Temp: A Thermo King truck or trailer unit capable of
maintaining different set-points in multiple compartments.
no. 1 diesel fuel: A grade of diesel fuel formulated to
prevent “jelling” in low ambient temperatures.
no. 2 diesel fuel: A grade of diesel fuel formulated for
moderate to warm ambient temperatures.
ohm: An electrical unit measuring the amount of resistance
(opposition to the current flow) in an electrical circuit.
pre-cooling: 1) To cool down an empty box
(temperature-controlled area) to the desired load temperature
prior to loading. 2) To cool cargo to a desired temperature
before loading.
99
Glossary
pre-heat: The heating of diesel engine glow plugs prior to
start-up. Some engines use an intake manifold heater rather
than glow plugs.
pre-trip inspection: Checking the operation of a
refrigeration system before loading.
psi: Pounds per square inch. A unit of pressure.
1 psi = 0.069 bar = 6.89 kPa.
return air bulkhead: A structure (metal or plastic) mounted
in the front of a trailer and designed to prevent restriction of
return air flow to the Thermo King unit due to improper
loading. See bulkhead.
return air temperature: The temperature of the air
returning to the evaporator. See box temperature.
rpm: Revolutions per minute.
psig: Pounds per Square Inch Gauge. Pressure in pounds per
square inch as displayed by a gauge calibrated to zero when
open to the atmosphere.

microprocessor controller. This is normally the desired box
temperature.
receiver tank: A refrigerant storage device included in
nearly all Thermo King units.
short cycling: When a refrigeration unit cycles between the
heat and cool modes more often than normal.
refrigerant: The medium of heat transfer in a refrigeration
system which absorbs heat by evaporating at a low temperature
and releases heat by condensing at a higher temperature.
sight glass: A system component that permits visual
inspection of oil or refrigerant level and condition.
refrigerant oil: A special oil used to lubricate compressors in
refrigeration systems.
remote evaporator: A separate evaporator unit located in a
second or third compartment of a multi-temperature truck or

thermostat: A device that controls unit modes of operation to
maintain a selected box temperature.
top freeze: When the top portion of perishable cargo is
damaged by freezing temperatures discharged from the
refrigeration unit. This may occur near the front of the box
when product is placed too close to the cold, discharge air flow.
Glossary
Vac (volts alternating current): An electric current that
reverses direction at regularly recurring intervals.
