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 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.

Automatic Start/Stop Operation

This unit is capable of automatic operation and could start at
any time without warning.

Electrical Hazard

Refrigerant

Although fluorocarbon refrigerants are classified as safe, use
caution when working with refrigerants or in areas where they
are being used.

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.

WARNING: The unit can start at any time without
warning. Press the O

FF

key on the HMI control panel
and place the microprocessor On/Off switch in the
Off position before inspecting or servicing any part of
the unit.

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.

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 DEA TH BY SUFFOCA TION. 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.

Diesel Engine

The Thermo King TK486 family of engines are 4-cylinder,
water cooled, direct injection diesel engines. The engine is
coupled directly to the compressor on the Model 30. A
centrifugal clutch transfers power from the engine to the
compressor on the Model 50. Belts transmit power to the unit
fans, alternator and water pump.

The SB-210+ uses a TK486V (Tier2), which is designed to run
with a high speed of 2200 rpm.

The SB-310+ uses a TK486VH (Tier2), which is designed to
run with a high speed of 2600 rpm.

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 (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.

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 3000-Hour Fuel Filter (black with gold lettering)

• EMI 3000-Hour Dual Element Oil Filter (black with gold
lettering)

• 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.

NOTE: The new EMI 3000 oil filters and new EMI 3000 air
cleaners are NOT interchangeable with the older style oil
filters and air cleaners.

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.

Thermo King X430L
Reciprocating Compressor

The unit is equipped with a Thermo King X430L reciprocating
compressor with 30 cu. in. (492 cm

3

) displacement.

Electronic Throttling Valve

The Electronic Throttling Valve (ETV) is optional on the
SB-210+ and standard on the SB-310+.

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.

You can tell if the unit has an ETV by looking at the
compressor. Units with an ETV have a suction valve adapter.
Units without an ETV have a mechanical throttling valve.

2. Mechanical Throttling Valve (No ETV)

SMART REEFER 2 (SR-2) Control
System

The SR-2 controller is a microprocessor control system
designed for transport refrigeration. The SR-2 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.
The microprocessor is connected to an HMI (Human Machine
Interface) Control Panel. It is used to operate the unit. The
HMI 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-2 controller.

Depending on the air temperature in the trailer, as sensed by
the microprocessor controller, the unit will typically operate in
one of the following modes:

CYCLE-SENTRY Operation

• High Speed Cool

• Low Speed Cool

• Null (Engine Off)

• Low Speed Heat

• High Speed Heat

•Defrost

Continuous Run Operation

• High Speed Cool

• Low Speed Cool

• Low Speed Modulated Cool (Optional SB-210+)

• Low Speed Modulated Heat (Optional SB-210+)

• Low Speed Heat

• High Speed Heat

•Defrost
