Safety Precautions
General Practices
1.ALWAYS WEAR GOGGLES OR SAFETY GLASSES.
Refrigerant liquid and battery acid can permanently damage the eyes (see First Aid under Refrigerant Oil).
2.Never close the compressor discharge valve with the unit
in operation. Never operate the unit with the discharge
valve closed.
3.Keep your hands, clothing and tools clear of the fans
when the refrigeration unit is running. If it is necessary to
run the refrigeration unit with covers removed, be very
careful with tools or meters being used in the area.
4.Be sure the gauge manifold hoses are in good condition.
Never let them come in contact with a fan motor blade or
any hot surface.
5.Never apply heat to a sealed refrigeration system or container.
6.Fluorocarbon refrigerants, in the presence of an open
flame or electrical arc, produce toxic gases that are severe
respiratory irritants capable of causing death.
7.Be sure all mounting bolts are tight and are the correct
length for their particular application.
8.Use extreme caution when drilling holes in the unit. The
holes may weaken structural components. Holes drilled into
electrical wiring can cause fire or explosion. Holes drilled
into the refrigeration system may release refrigerant.
9.Use caution when working around exposed coil fins. The
fins can cause painful lacerations.
10. Use caution when working with a refrigerant or refrigeration system in any closed or confined area with a limited
air supply (for example, a trailer, container or in the hold
of a ship). Refrigerant tends to displace air and can cause
oxygen depletion, resulting in suffocation and possible
death.
11. Use caution and follow the manufacturer’s suggested
practices when using ladders or scaffolds.
Refrigerant
When removing any refrigerant from a unit, use a recovery
process that prevents or absolutely minimizes the refrigerant
that can escape to the atmosphere. Although fluorocarbon
refrigerants are classified as safe refrigerants when proper
tools and procedures are used, certain precautions must be
observed when handling them or servicing a unit in which they
are used. When exposed to the atmosphere in the liquid state,
fluorocarbon refrigerants evaporate rapidly, freezing anything
they contact.
First Aid
In the event of frost bite, the objectives of First Aid are to protect the frozen area from further injury, to warm the affected
area rapidly, and to maintain respiration.
•EYES: For contact with liquid, immediately flush eyes
with large amounts of water and get prompt medical attention.
•SKIN: Flush area with large amounts of lukewarm water.
Do not apply heat. Remove contaminated clothing and
shoes. Wrap burns with dry, sterile, bulky dressing to
protect from infection/injury. Get medical attention.
Wash contaminated clothing before reuse.
•INHALATION: Move victim to fresh air and use CPR or
mouth-to-mouth ventilation, if necessary. Stay with victim
until arrival of emergency medical personnel.
CSR40-149 & -150 PS Hermetic, June 2000
viiiRefrigerant OilSafety Precautions
4.Do not make any rapid moves when working on high volt-
Refrigerant Oil
Observe the following precautions when working with or
around refrigerant oil:
•Do not allow refrigerant oil to contact your eyes.
•Do not allow prolonged or repeated contact with skin or
clothing.
•To prevent irritation, you should wash thoroughly immediately after handling refrigerant oil. Rubber gloves are
recommended when handling Polyol Ester based refrigerant oil.
First Aid
•EYES: Immediately flush eyes with large amounts of
water for at least 15 minutes while holding the eyelids
open. Get prompt medical attention.
•SKIN: Remove contaminated clothing. Wash thoroughly
with soap and water. Get medical attention if irritation
persists.
•INHALATION: Move victim to fresh air and restore
breathing if necessary. Stay with victim until arrival of
emergency personnel.
•INGESTION: Do not induce vomiting. Contact a local
poison control center or physician immediately.
Electrical
High Voltage
When servicing or repairing a refrigeration unit, the possibility
of serious or even fatal injury from electrical shock exists.
Extreme care must be used when working with a refrigeration
unit that is connected to a source of operating power, even if
the unit is not running. Lethal voltage potentials can exist at
the unit power cord, inside the control box, inside any high
voltage junction box, at the motors and within the wiring harnesses.
Precautions
1.Be certain the unit On/Off switch is turned OFF before
connecting or disconnecting the unit power plug. Never
attempt to stop the unit by disconnecting the power plug.
2.Be certain the unit power plug is clean and dry before
connecting it to a power source.
3.Use tools with insulated handles that are in good condition. Never hold metal tools in your hand if exposed,
energized conductors are within reach.
age circuits. If a tool or other object falls, do not attempt
to grab it. People do not contact high voltage wires on
purpose. It occurs from an unplanned movement.
5.Treat all wires and connections as high voltage until a
meter and wiring diagram show otherwise.
6.Never work alone on high voltage circuits on the refrigeration unit. Another person should always be standing by
in the event of an accident to shut off the refrigeration unit
and to aid a victim.
7.Have electrically insulated gloves, cable cutters and safety
glasses available in the immediate vicinity in the event of
an accident.
First Aid
IMMEDIATE action must be initiated after a person has
received an electrical shock. Obtain immediate medical assistance if available.
The source of shock must be immediately removed by
either shutting down the power or removing the victim from
the source. If it is not possible to shut off the power, the wire
should be cut with either an insulated instrument (e.g., a wooden handled axe or cable cutters with heavy insulated handles)
or by a rescuer wearing electrically insulated gloves and safety
glasses. Whichever method is used, do not look at the wire
while it is being cut. The ensuing flash can cause burns and
blindness.
If the victim has to be removed from a live circuit, pull the
victim off with a non-conductive material. Use the victim’s
coat, a rope, wood, or loop your belt around the victim’s leg or
arm and pull the victim off. DO NOT TOUCH the victim.
You can receive a shock from current flowing through the victim’s body.
After separating the victim from power source, check
immediately for the presence of a pulse and respiration. If a
pulse is not present, start CPR (Cardio Pulmonary
Resuscitation) and call for emergency medical assistance. If a
pulse is present, respiration may be restored by using mouthto-mouth resuscitation, but call for emergency medical assistance.
Low Voltage
Control circuits are low voltage (24 Vac and 12 Vdc). This
voltage potential is not considered dangerous, but the large
amount of current available (over 30 amperes) can cause
severe burns if shorted to ground.
Do not wear jewelry, watch or rings. These items can short
out electrical circuits and cause severe burns to the wearer.

Safety PrecautionsGeneral Safety Precautions for Servicing Controllersix
Welding of Units or Containers
General Safety Precautions for Servicing
Units (or Containers) Equipped with a
Microprocessor Controller
Precautions must be taken to prevent electrostatic discharge
when servicing the MP-3000 microprocessor and related components. If these precautionary measures are not followed, the
risk of significant damage to the electronic components of the
unit is possible.
The primary risk potential results from the failure to wear
adequate electrostatic discharge preventive equipment when
handling and servicing the controller. The second cause
results from electric welding on the unit and container chassis
without taking precautionary steps.
Controller Repair
When servicing the controller, it is necessary to ensure that
electrostatic discharges are avoided. Potential differences considerably lower than those which produce a small spark from a
finger to a door knob can severely damage or destroy solidstate integrated circuit components. The following procedures
must be rigidly adhered to when servicing these units to avoid
controller damage or destruction.
1.Disconnect all power to the unit.
2.Avoid wearing clothing that generates static electricity
(wool, nylon, polyester, etc.).
3.Do wear a static discharge wrist strap (TK P/N 204-622)
with the lead end connected to the controller's ground ter-
minal. These straps are available at most electronic equip-
ment distributors. DO NOT wear these straps with power
applied to the unit.
4.Avoid contacting the electronic components on the circuit
boards of the unit being serviced.
5.Leave the circuit boards in their static proof packing mate-
rials until ready for installation.
6.If a defective controller is to be returned for repair, it
should be returned in the same static protective packing
materials from which the replacement component was
removed.
7.After servicing the circuit board and any other circuits, the
wiring should be checked for possible errors before restor-
ing power.
Whenever electric welding is to be performed on any portion
of the refrigeration unit, container or container chassis with the
refrigeration unit attached, it is necessary to ensure that welding currents are NOT allowed to flow through the electronic
circuits of the unit. These procedures must be rigidly adhered
to when servicing these units to avoid damage or destruction.
1.Disconnect all power to the refrigeration unit.
2.Disconnect all quick-disconnect wire harnesses from the
back of the controller.
3.If the unit is equipped with an Remote Monitor Modem
(RMM), disconnect all wire harnesses from the RMM.
4.Switch all of the electrical circuit breakers in the control
box to the OFF position.
5.Weld unit and/or container per normal welding procedures. Keep ground return electrode as close to the area to
be welded as practical. This will reduce the likelihood of
stray welding currents passing through any electrical or
electronic circuits.
6.When the welding operation is completed, the unit power
cables, wiring and circuit breakers must be restored to
their normal condition.

Introduction.
Hermetic Scroll Compressor with Liquid Injection
Cooling System
The refrigeration unit includes a hermetic scroll compressor
(one stationary and one orbiting member) with ambient compensated internal overload and high temperature protectors,
and a refrigerant injection system.
CSR PS models are equipped with either 2 or 3 evaporator fans.
All models feature 2-speed motors. The evaporator fans operate
continuously to circulate air inside the container. The fans operate on high speed for perishable cargo at setpoints of -9.9 C
(14.1 F) and above. At setpoints of -10 C (14 F) and below, the
evaporator fans operate on low speed for frozen cargo.
NOTE: If Economy Mode is ON:
• Fresh Loads: Evaporator fans operate on low
speed when container temperature is in-range.
• Frozen Loads: Evaporator fans stop during the
Null mode; controller operates fans on low speed
for 5 minutes every 45 minutes.
Fresh Air Exchange System
The fresh air exchange system removes harmful gases from
containers carrying sensitive perishable commodities. The
fresh air vent is located above the control box. The fresh air
vent is adjustable to accommodate a variety of cargo and
chilled load operating conditions. The fresh air vent should be
tightly closed when carrying frozen cargo.
MP-3000 Controller
The MP-3000 controller incorporates refrigeration system
component control, thermostat, digital thermometer, fault indication and data recording capabilities into one self-contained
package.
The controller mounts in a weather tight, corrosion resistance enclosure. A large-character LED display (top) provides
easy viewing of the control sensor temperature (return or supply air temperature). A 4-line, 20-character LCD display (bottom) display shows important data including the setpoint temperature, controller Main Menu tree and important unit operating data.

shutdown indications. All data recordings are stored in a
RAM memory that is backed by battery.
Logging intervals are selectable from 1 minute and 1/2, 1,
2 or 4 hours. When a 1 hour logging interval is selected, the
datalogger memory can store approximately 680 days of information. The logging of USDA sensors is fixed at 1 hour intervals to comply with USDA requirements.
The datalogger clock is factory set at UTC time. All data
logs include the time and date; setpoint temperature; and supply, return, USDA1, USDA2 and USDA3 sensor temperatures.
All temperature logs can be viewed from the controller’s LCD
message display.
A high speed serial communication port provides data
retrieval using a DRU-II hand-held data retriever or laptop
computer with SmartSponge software, or a REFCON power
line remote monitoring system.
Unit Options
Advanced Fresh Air Management (AFAM)
An advanced microprocessor controlled fresh air management
system provides programmable control of the air exchange
rate, programmable delayed vent opening, automatic air
exchange lock out for frozen cargo, automatic closure of the
air exchange vent when the ambient temperature decreases
below the cargo setpoint temperature, and data logging of the
air exchange rate and vent opening delay interval.
The AFAM system includes a door control module, vent
door, calibration decal and vent grille. The MP-3000 controller sends a communication signal to the door control module to position to vent door to the desired position. The controller can also be set to delay opening of the fresh air vent for
up to 72 hours, in 1-hour increments. This allows faster product temperature pulldown.
The system is precalibrated for air exchange rates of 0 to
285 m3/hr (0 to 168 ft3/min.). A calibrated decal located
inside the air exchange vent compartment can be used to visually verify the air exchange rate setting.
Dehumidification Control System
A dehumidification system lowers the relative humidity in the
container to the humidity setpoint. The control range is 50%
to 99% while the setpoint is adjustable between 0% and 99%.
Humidification Control System
An optional humidification system increases the relative
humidity in the container to the humidity setpoint. The control
range is 50% to 99% while the setpoint is adjustable between
0% and 99%.
Dual Voltage
A dual voltage system includes a 15 KVA auto transformer
and an 18.3 m (60 ft) power cable for operation on 230190V/3 Ph/60-50 Hz power. The power cable is stored below
the control box in the condenser section.
The 15 KVA auto transformer steps 230/190V power up

energize, the controller LCD display shows the setpoint temperature. The controller LED display shows the controlling air
sensor temperature. The controlling sensor is determined by
the setpoint temperature:
SetpointControlling Sensor
-9.9 C (14.1 F) and aboveSupply Air Temperature
-10 C (14 F) and belowReturn Air Temperature
The MP-3000 controller uses a proportional-integral
derivative (PID) algorithm to provide accurate temperature
control in direct response to load demand. Therefore it is difficult to predict which operating mode the unit should be in by
comparing the setpoint to the return or supply air temperature.
The unit operates in either the Fresh (Chill) or Frozen mode.
Chill to Frozen mode transition point is -10 C (14 F).
Temperature control by the controller is based on the return air
sensor temperature. The evaporator fans operate continuously
on low speed (except during defrost).
• Cool (down to 1 C [1.8 F] below setpoint)
• Null (compressor and condenser fan stops, evaporator
fans operate)
• Defrost (resistance heaters on, evaporator fans stop)
NOTE: If the Economy Mode is set to ON, the
evaporator fans stop when the unit shifts to Null.
The controller automatically starts and operates
the evaporator fans on low speed for 5 minutes
every 45 minutes while the unit remains in Null.

Chill Loads: Controller Setpoint at -9.9 C (14.1 F) or
Above
Temperature control by the controller is based on the supply
air sensor temperature, the setpoint, the modulation temperature range and the pull-down rate. The evaporator fans operate
in high speed (except during defrost).
• Cool with Modulation (down to setpoint)
• Null (compressor and condenser fan stops, evaporator
fans operate)
• Heat (resistance heaters on, evaporator fans operate)
• Defrost (resistance heaters on, evaporator fans stop)
NOTE: If the Economy Mode is set to ON, the
evaporator fans operate on low speed at setpoints of -9.9 C (14.1 F) and above whenever the
container temperature is In-range.
