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
Automatic Start/Stop Operation
This unit is capable of automatic operation and could start at
any time without warning.
WARNING: Keep hands and loose clothing clear of
fans and belts at all times when the unit is operating
with the doors open.
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.
WARNING: The unit can start at any time without
warning. Press the OFF key on the control panel and
place the microprocessor On/Off switch in the Off
position before inspecting or servicing any part of the
unit.

Safety Precautions
9
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.
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.
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
10
Refrigerant
Although fluorocarbon refrigerants are classified as safe, use
caution when working with refrigerants or in areas where they
are being used.
NOTE: These warnings refer to servicing of the unit.

Unit Description
General Information
The Thermo King SLXi models are one piece, self-contained,
diesel powered cooling/ heating units operating under the
control of a Smart Reefer 3 (SR-3) programmable
microprocessor controller. The units mount on the front of the
trailer with the evaporator extending through an opening in the
front wall.
There are models:
• SLXi-100, 200, 300, 400, and 300 Whisper Pro Model
30's: Cooling and heating on diesel engine operation.
• SLXi-100, 200, 300, 400 and 300 Whisper Pro Model

or electric motor operation. Figure 4: Front View

Unit Description
16
Diesel Engine
SLXi units use a 4-cylinder, water cooled, direct injection
diesel engine. The engine is coupled directly to the compressor
on standard units. Belts transmit power to the to fans (behind
the condenser coil/radiator), water pump, and alternator on all
models.
ELC (Extended Life Coolant)
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. The new engine coolant, Chevron Extended Life
Coolant, is RED in color instead of the previous GREEN or
BLUE-GREEN colored conventional coolants.
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.
EMI 3000
EMI 3000 is an extended maintenance interval package. It is
standard equipment. The EMI 3000 package consists of the
following key components:
• EMI 3000-Hour Cyclonic Air Cleaner Assembly and Air
Cleaner Element
• EMI 5-Micron 3000-Hour Fuel Filter
• EMI 3000-Hour Dual Element Oil Filter
• API Rating CI-4 Mineral Oil
• Five Year or 12,000 Hour ELC (Extended Life Coolant)
The EMI package allows standard maintenance intervals to be
extended to 3,000 hours, or 2 years, whichever occurs first.
NOTE: Units equipped with the EMI 3000 package do
require regular inspection in accordance with Thermo King's
maintenance recommendations.
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.

Unit Description

Thermo King Reciprocating
Compressor
The SLXi units (except SLXi-100) are equipped with a
4-cylinder 492 cm3 (30.0 cu. in.) displacement Thermo King
X430 reciprocating compressor. The SLXi-100 unit is
equipped with a 4-cylinder 426 cm3 (25.9 cu. in.) displacement
Thermo King X426 reciprocating compressor.
Electronic Throttling Valve
NOTE: SLXi-100 or SLXi-200 are equipped with a
Mechanical Throttling Valve (MTV).
The ETV provides enhanced control of the refrigeration system
as follows:
• Allows the refrigeration system to fully utilize the power
capabilities of the engine under varying conditions
• Provides an additional measure of protection against high
discharge pressures
• Protects the engine from high coolant temperature
shutdowns
• Provides a means of precise temperature control.
SMART REEFER 3 (SR-3) Control
System
The SR-3 is a microprocessor control system designed for
transport refrigeration. The SR-3 integrates the following
functions: changing setpoint and operating mode, viewing
gauge, sensor and hourmeter readings, initiating defrost cycles,
and viewing and clearing alarms.
The microprocessor components are located inside the control
box, which is located inside the lower roadside service door. It
is used to operate the unit. The control panel is mounted on the
face of the control box. It is clearly visible through an opening
in the lower roadside service door.
See “Operating Instructions” for more information about the
SR-3 Controller.
Depending on the air temperature in the trailer, as sensed by
the microprocessor Base Controller, the unit will typically
operate in one of the following modes:
