Chapter 1: Safety Precautions

1.1: General Practices

    Danger
  • Hazard of Explosion
  • Never apply heat to a sealed refrigeration system or container. Heat increases internal pressure, which might cause an explosion resulting in death or serious injury.
    Danger
  • Hazardous Gases - Personal Protective Equipment (PPE) Required
  • Refrigerant in the presence of an open flame, spark, or electrical short produces toxic gases that are severe respiratory irritants which can cause serious injury or possible death. When working with or around hazardous chemicals, ALWAYS refer to the applicable Material Data Safety Sheets (MSDS) and OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection, and handling instructions.
    Danger
  • Risk of Injury
  • Keep your hands, clothing, and tools clear of fans and/or belts when working on a unit that is running or when opening or closing compressor service valves. Loose clothing might entangle moving pulleys or belts, causing serious injury or possible death.
    Danger
  • Refrigerant Vapor Hazard
  • Do not inhale refrigerant. Use caution when working with refrigerant or a refrigeration system in any confined area with a limited air supply. Refrigerant displaces air and can cause oxygen depletion, resulting in suffocation and possible death. When working with or around hazardous chemicals, ALWAYS refer to the applicable Material Data Safety Sheets (MSDS) and OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection, and handling instructions.
    Warning
  • Hazard of Explosion
  • Never close the compressor discharge service valve when the unit is operating. Never operate the unit with the discharge valve closed (front seated). This condition increases internal pressure, which can cause an explosion.
    Warning
  • Proper Equipment Condition
  • Gauge manifold hoses must be in good condition before using them. Never let them come in contact with moving belts, fans, pulleys or hot surfaces. Defective gauge equipment can damage components or cause serious injury.
    Warning
  • Personal Protective Equipment (PPE) Required
  • Always wear goggles or safety glasses and proper PPE when working on a unit. Refrigerant liquid, oil, and battery acid can permanently damage your eyes. When working with or around hazardous chemicals, ALWAYS refer to the applicable Material Data Safety Sheets (MSDS) and OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection, and handling instructions.
    Warning
  • Equipment Damage and Risk of Injury
  • Never drill holes into the unit unless instructed by Thermo King. Holes drilled into high voltage cables could cause an electrical fire, severe personal injury, or even death.
    Warning
  • Risk of Injury
  • When using ladders to install or service refrigeration systems, always observe the ladder manufacturer’s safety labels and warnings. A work platform or scaffolding is the recommended method for installations and servicing.
    Caution
  • Sharp Edges
  • Exposed coil fins can cause lacerations. Service work on the evaporator or condenser coils should only be accomplished by a certified Thermo King technician.
    Notice
  • Equipment Damage
  • All unit mounting bolts must be installed, be the correct length for their application, and torqued to specifications. Missing bolts, incorrect bolt lengths and improper torque specifications can damage equipment and void the warranty.

1.2: Refrigerant Hazards

    Danger
  • Hazardous Pressures
  • Always store refrigerant in proper containers, out of direct sunlight and away from intense heat. Heat increases pressure inside storage containers, which can cause them to burst and could result in severe personal injury.
    Danger
  • Combustible Hazard
  • Do not use oxygen (O2 ) or compressed air for leak testing. Oxygen mixed with refrigerant is combustible.
    Warning
  • Hazardous Gases
  • Do not use a Halide torch. When a flame comes in contact with refrigerant, toxic gases are produced. These gases can cause suffocation, even death.
    Warning
  • Personal Protective Equipment (PPE) Required
  • Refrigerant in a liquid state evaporates rapidly when exposed to the atmosphere, freezing anything it contacts. Wear butyl lined gloves and other clothing and eye wear when handling refrigerant to help prevent frostbite. When working with or around hazardous chemicals, ALWAYS refer to the applicable Material Data Safety Sheets (MSDS) and OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection, and handling instructions.
    Notice
  • Equipment Damage
  • When being transferred, refrigerant must be in liquid state to avoid possible equipment damage.

1.3: Electrical Hazards

Electrical Precautions

  • The possibility of serious or fatal injury from electrical shock exists when servicing a refrigeration unit. Extreme care must be used when working with a refrigeration unit that is connected to its power source.

  • Extreme care must be used 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.

  • In general, disconnect the units power cord before repairing or changing any electrical components.

  • Even though the controller is turned off, one of the phases is still live and represents a potential danger of electrocution.

  • Disconnect power at Main Circuit Breaker and remove power plug from the high voltage socket. Lock-out-tag out as required.

High Voltage

    Danger
  • Hazardous Voltage
  • Lethal amounts of voltage are present in some electrical circuits. Use extreme care when working on the refrigeration unit. If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other local, state, or country-specific requirements for arc flash protection PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASHING CLOTHING. ELECTRICAL METERS AND EQUIPMENT MUST BE PROPERLY RATED FOR INTENDED VOLTAGE.
    Warning
  • Hazardous Voltage
  • Treat all wires and connections as if they were high voltage until a meter and wiring diagram indicate otherwise. Only use tools with insulated handles. Never hold uninsulated metal tools near exposed, energized conductors. If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other local, state, or country-specific requirements for arc flash protection PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASHING CLOTHING. ELECTRICAL METERS AND EQUIPMENT MUST BE PROPERLY RATED FOR INTENDED VOLTAGE.
    Warning
  • Hazardous Voltage
  • Never work alone on high voltage circuits in the refrigeration unit. Another person should be nearby to shut off the unit and provide aid in the event of an accident. If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other local, state, or country-specific requirements for arc flash protection PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASHING CLOTHING. ELECTRICAL METERS AND EQUIPMENT MUST BE PROPERLY RATED FOR INTENDED VOLTAGE.
    Warning
  • Personal Protective Equipment (PPE) Required
  • In the event of an electrical accident, all required PPE should be near the work area in accordance with OSHA, NFPE 70E, or other local, state, or country-specific requirements for a Category 3 risk.
    Warning
  • Hazardous Voltage
  • The unit On/Off switch must be turned Off before connecting or disconnecting the standby power plug. Never attempt to stop the unit by disconnecting the power plug.
    Warning
  • Risk of Injury
  • The unit power plug must be clean and dry before connecting it to a power source.
    Warning
  • Risk of Injury
  • Do not make rapid moves when working on high voltage circuits in the refrigeration unit. Do not grab for falling tools because you might accidentally touch a high voltage source.

Low Voltage

    Warning
  • Live Electrical Components
  • Control circuits are low voltage (24 Vac and 12 Vdc). This voltage potential is not considered dangerous. 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 shortcut electrical circuits and cause severe burns to the wearer.

1.4: Electrostatic Discharge Precautions

Precautions must be taken to prevent electrostatic discharge while servicing the microprocessor controller and related components. The risk of significant damage to the electronic components of the unit is possible if these precautionary measures are not followed. 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.

Electrostatic Discharge and the Controller

You must avoid electrostatic discharges when servicing the controller. Solid-state integrated circuit components can be severely damaged or destroyed with less than a small spark from a finger to metal object. You must rigidly adhere to the following statements when servicing these units. This will avoid controller damage or destruction.

  • Disconnect all power to the unit.

  • Avoid wearing clothing that generates static electricity (wool, nylon, polyester, etc.).

  • Do wear a static discharge wrist strap (refer to Tool Catalog) with the lead end connected to the controller's ground terminal. These straps are available at most electronic equipment distributors. Do not wear these straps with power applied to the unit.

  • Avoid contacting the electronic components on the circuit boards of the unit being serviced.

  • Leave the circuit boards in their static proof packing materials until ready for installation.

  • Return a defective controller for repair in the same static protective packing materials from which the replacement component was removed.

  • Check the wiring after servicing the unit for possible errors. Complete this task before restoring power.

1.5: Welding on Refrigeration Units or Containers

Electric welding can cause serious damage to electronic circuits when performed on any portion of the refrigeration unit, genset, container, or container chassis with the refrigeration unit attached. It is necessary to verify that welding currents are not allowed to flow through the electronic circuits of the unit. The procedures below MUST be strictly followed when servicing units to avoid damage or destruction of the microprocessor.

  1. Disconnect the battery connections (if equipped) and lock out - tag out the unit according to local regulations.

  2. Disconnect all power to or from the refrigeration unit or genset.

  3. Disconnect all quick-disconnect wire harnesses from the back of the controller.

  4. Switch all of the electrical circuit breakers in the control box to the Off position.

  5. When steps 1 through 5 are complete, weld the unit and/or container using 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 welding is complete, restore the unit power cables, wiring, and circuit breakers to their normal condition.

1.6: First Aid

REFRIGERANT

  • 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 warm water. Do not apply heat. Remove contaminated clothing and shoes. Wrap burns with dry, sterile, bulky dressing to protect from infection. Get prompt medical attention. Wash contaminated clothing before reuse.

  • Inhalation: Move victim to fresh air and use Cardio Pulmonary Resuscitation (CPR) or mouth-to-mouth resuscitation to restore breathing, if necessary. Stay with victim until emergency personnel arrive.

  • Frost Bite: In the event of frost bite , the objectives of First Aid are to protect the frozen area from further injury, warm the affected area rapidly, and to maintain respiration.

REFRIGERANT OIL

  • Eyes: Immediately flush with large amounts of water for at least 15 minutes. 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 use Cardio Pulmonary Resuscitation (CPR) or mouth-to-mouth resuscitation to restore breathing, if necessary. Stay with victim until emergency personnel arrive.

  • Ingestion: Do not induce vomiting. Immediately contact local poison control center or physician.

ENGINE COOLANT

  • Eyes: Immediately flush with large amounts of water for at least 15 minutes. Get prompt medical attention.

  • Skin: Remove contaminated clothing. Wash thoroughly with soap and water. Get medical attention if irritation persists.

  • Ingestion: Do not induce vomiting. Immediately contact local poison control center or physician.

BATTERY ACID

  • Eyes: Immediately flush with large amounts of water for at least 15 minutes. Get prompt medical attention. Wash skin with soap and water.

  • Skin: Immediately remove contaminated clothing. Wash skin with large volumes of water, for at least 15 minutes. Wash skin with soap and water. Do not apply fatty compounds. Seek immediate medical assistance.

  • Inhalation: Provide fresh air. Rinse mouth and nose with water. Seek immediate medical assistance.

  • Ingestion: If the injured person is fully conscious: make the person drink extensive amounts of milk. Do not induce vomiting. Take the injured person immediately to a hospital.

ELECTRICAL SHOCK

Take IMMEDIATE action after a person has received an electrical shock. Get quick medical assistance, if possible.

The source of the shock must be quickly stopped, by either shutting off the power or removing the victim. If the power cannot be shut off, the wire should be cut with an non-conductive tool, such as a wood-handle axe or thickly insulated cable cutters. Rescuers should wear insulated gloves and safety glasses, and avoid looking at wires being cut. The ensuing flash can cause burns and blindness.

If the victim must be removed from a live circuit, pull the victim away with a non-conductive material. Use wood, rope, a belt or coat to pull or push the victim away from the current. DO NOT TOUCH the victim. You will receive a shock from current flowing through the victim’s body. After separating the victim from power source, immediately check for signs of a pulse and respiration. If no pulse is present, start Cardio Pulmonary Resuscitation (CPR). If a pulse is present, respiration might be restored by using mouth-to-mouth resuscitation. Call for emergency medical assistance.

ASPHYXIATION

Move victim to fresh air and use Cardio Pulmonary Resuscitation (CPR) or mouth-to-mouth resuscitation to restore breathing, if necessary. Stay with victim until emergency personnel arrive.

MP–5000 Controller Specification

Temperature Controller:
Type MP-5000 is a controller module for the Thermo King Magnum Plus and CFF unit models. Additional requirements can be met by means of expansion modules. The MP–5000 is solely responsible for temperature regulation of the reefer container, but other monitoring equipment can be used in conjunction with the MP-5000, such as a telematics device.
Setpoint Range

-40.0 to +30.0 C (-40.0 to +86.0 F) — Magnum Plus™

-30.0 to +30.0 C (-22.0 to +86.0 F) — CFF
Temperature Display Range -70.0 to +80.0 C (-94.0 to +176.0 F)
Controller Software  
Version See controller display for SW version
Defrost Initiation:
Evaporator Coil Sensor Manual Switch or Demand Defrost Initiation: Coil must be below 18 C (65 F). Defrost cycle starts when technician or controller requests defrost initiation.
Timed Defrost Initiation: Coil must be below 4 C (41 F). Defrost cycle starts 1 minute after the hour immediately following a defrost timer request for defrost initiation. For example, if the defrost timer requests a defrost cycle at 7:35, the defrost cycle will start at 8:01. Datalogger will record a Defrost event for each interval in which a Defrost cycle is pending or active (i.e. both the 8:00 and 9:00 data logs).
Demand Defrost Demand defrost function initiates defrost when: Temperature difference between the return air sensor and defrost (evaporator coil) sensor is too large for 90 minutes Temperature difference between the supply air sensors and return air sensor is too large
 
 
Defrost Timer:
Chilled mode Evaporator Coil Temperature must be below 5C (41 F) to activate the defrost compressor hour timer.
Chilled Mode (continued) There is an interval set for defrosting, however, the defrost timer is built intelligent - it detects whether or not there is ice building up on the coil. If there is no ice building up on the coil, it extends the defrost interval, and if there is Ice building up earlier on the coil it reduces the defrost interval. The maximum interval is 48 hours.
Frozen mode Every 8 hours of compressor operation. Defrost interval increases 2 hours each timed defrost interval. Maximum time interval in Frozen mode is 24 hours.
Reset to Base Time Defrost timer resets if the unit is off more than 12 hours, setpoint is changed more than 5 C (9 F) or PTI pretrip test occurs.
Defrost Termination:
Defrost (Coil) Sensor Chilled mode: Terminates defrost when coil sensor temperature rises to 18 C (65 F). Frozen mode: Terminates defrost when coil sensor temperature rises to 18 C (65 F).
Termination Timer Terminates defrost after 90 minutes at 60 HZ operation if coil sensor has not terminated defrost (120 minutes at 50 Hz operation)
Power Off Turning Unit On/Off switch Off terminates defrost
Compressor Shutdown Protection (Auto Reset):
Stops Compressor 148 C (298 F)
Allows Compressor Start 90 C (194 F)
Bulb Mode:
Evaporator Fan Speed Settings Flow High: High speed only
Flow Low: Low speed only
Flow Cycle: Fans will cycle between low and high speed every 60 minutes
Defrost Termination Temperature Setting 4 to 30 C (40 to 86 F)
