SAFETY SUMMARY
GENERAL SAFETY NOTICES
The following general safety notices supplement the specific warnings and cautions appearing elsewhere in this manual. They are recommended precautions that must be understood and applied during operation and maintenance of the equipment covered herein. The general safety noticesare presentedin the following three sections labeled:First Aid, Operating Precautions and Maintenance Precautions. A listing of the specific warnings and cautions appearing elsewhere in the manual follows the general safety notices.
FIRST AID
An injury, no matter how slight, shouldnever go unattended.Always obtain firstaid or medicalattention immediately.
OPERATING PRECAUTIONS
Always wear safety glasses.
Keep hands, clothing and tools clear of the evaporator and condenser fans.
No work should be performed on the unit until all circuit breakers and start-stop switches are turned off, and power supply is disconnected.
Always work in pairs. Never work on the equipment alone.
In case of severe vibration or unusual noise, stop the unit and investigate.
SAFETY SUMMARY
MAINTENANCE PRECAUTIONS
Beware of unannounced starting of the evaporator and condenser fans. Do not open the condenser fan grille or evaporator access panels before turning power off, and disconnecting and securing the power plug.
Be surepower is turned off beforeworking on motors, controllers,solenoid valves and electricalcontrol switches. Tag circuit breaker and power supply to prevent accidental energizing of circuit.
Do not bypass any electrical safety devices, e.g. bridging an overload, or using any sort of jumper wires. Problems with the system should be diagnosed, and any necessary repairs performed, by qualified service personnel.
When performing any arcwelding on the unit or container,disconnect all wire harness connectors fromthe modules in the control box. Do not remove wire harness from the modules unless you are grounded to the unit frame with a static-safe wrist strap.
In case of electrical fire, open circuit switch and extinguish with CO
(never use water).

SPECIFIC WARNING AND CAUTION STATEMENTS
To help identify the label hazards on the Unit and explain the level of awareness each one carries, an explanation is given with the appropriate consequences:
DANGER -- means an immediate hazard which WILL result in severe personal injury or death.
WARNING -- means to warn against hazards or unsafe conditions which COULD result in seve re personal injury or death.
CAUTION -- means to warn against potential hazard or unsafe practice which COULD result in minor personal injury, product or property damage.
The statements listed below are applicable to the refrigeration unit and appear elsewhere in this manual. These rec­ommended precautions must be understood and applied during operation and maintenance of the equipment covered herein.
WARNING
When servicing the unit, use caution when handling R-134a. The refrigerant when in contact with
high temperatures (about 1000_F) will decompose into h ighly corrosive and toxic compounds.
WARNING
Be sure to avoid refrigerant coming in contact with the eyes. S hould refrigerant come in contact
with the eyes, wash eyes for a minimum of 15 minutes with potable water only. THE USE OF
MINERAL OIL OR REFRIGERANT OILS IS NOT RECOMMENDED.
WARNING
Be sure to avoid refrigerant coming in contact with the skin. Should refrigerant come in contact
with the skin, it should be treated as if the skin had been frostbitten or frozen.
WARNING
Be sure ventilation in the workspace is adequate to keep the concentration of refrigerant below
1000 parts per million. If necessary, use portable blowers.
WARNING
Beware of rotating fan blades and unannounced starting of fans.
WARNING
Do not use a nitrogen cylinder without a pressure regulator. Never mix refrigerants with air for
leak testing. It has been determined that pressurized, air-rich mixtures of refrigerants and air can
undergo combustion when exposed to an ignition source.
WARNING
Never fill a refrigerant cylinder beyond its rated capacity. Cylinder may rupture due to excessive
pressure when exposed to high temperatures.
WARNING
When starting the unit, be sure that all manual refrigerant valves in the discharge line are open.
Severe damage could occur from extremely high refrigerant pressures.

INTRODUCTION
1.1 INTRODUCTION
WARNING
It has been determined that pressurized, air-rich mixtures of refrigerants and air can undergo combustion when exposed to an ignition source.
This manual contains Operating Data, Electrical Data and Service Instructions for the refrigeration units listed in Table 1-1. Also, Table 1-1 charts some significant differences between these models.
NOTE
Beginning with early 1995 production, in addition to a model number, Carrier Transicold began usinga parts identification(PID) number in the format NT0000. In the parts manual, the PID number is shown in boldface to point out parts variations within models. The PID number must be included when ordering and inquiring about your unit.
The unit, of lightweight aluminum frame construction, is an all electric, one piece, self-contained cooling and heating refrigeration unit. The unit is designed to fit in the frontof a container and to serve as the container front wall. Forklift pockets are provided for installation and removal of the unit.
The unit is complete with a charge of R-134a, compressor lubricating oil (approved POE SW20 compressor oil for R-134a only), mode indicating lights, and temperature controller, and is ready for operation upon installation.
Some units are equipped with a two-speed compressor that is used to enhance power saving.
Some units aredual voltage units designed to operateon 190/230 or 380/460 volts AC, 3-phase, 50-60 hertz power (refer to section 2.4). Other units are designed to operate on 380/460 volts AC, 3-phase 50/60 hertz power only. An external autotransformeris required for 190/230 vac operation (refer to Figure 2-9 and section
2.4).
Operating control power is provided by a control transformer which steps down the AC supply power source to 18 and 24 volts AC , single phase control power.
The temperature Controller/DataCORDER (Micro-Link 2i) is a micropr oce ssor- ba sed controller and a integr ate d electronic data logging device. Refer to sections 3.1 and
3.3. Once the temperature controller is set at a desired container temperature, the unit w ill operate automatically to maintain the desired temperature within very close limits. The control system automatica lly selects cooling, holding or heating as necessar y to maintain the de sir ed temperature within the container.
WARNING
Beware of unannounced start ing of the evaporator and condenser fans. Do not open the condenser fan grille before turning power OFF and disc onnecting power plug.
Some units are equipped with a mechanical temperature recorder.
Some units may have a TransFRESH controlled atmosphere system added. Contact TransFRESH Corporation, P.O. Box 1788, Salinas, CA 93902 for information on their system.

b. Evaporator Section
The evaporator section contains the optional mechanical temperature recording bulb, return recorder sensor (RRS), return temperature sensor (RTS), thermostatic expansion valve, dual-speed evaporator fan motors and fans (2), evaporator coil and heaters, drain pan and heater, defrost termination sensor, heat termination thermostat, and heat exchanger. See Figure 2-2 and Figure 2-5 for sensor locations.
When transporting perishable (chilled) commodities, the fan motors will normally be in high speed above
-- 1 0 _C(+14_ F), or --5_C(+23_F) optiona lly.
The evaporator coil heaters are accessible by removing the front lower access panel. The defrost termination sensor (DTS) is located on the coil center tube sheet and may be serviced by removing the upper rear panel, or by removing the left front upper access panel, disconnecting the evaporator fan connector and reaching through the access panel opening.
The evaporator fans circulate air throughout the container by pulling air in the top of the refrigeration unit, directing the air through the evaporator coil where it is either heated or cooled, and discharging t he air through the bottom of the refrigeration unit into the container.
WARNING
Before servicing unit, make sure the unit circuit breakers (CB-1 & CB-2) and the start-stop switch (ST) are in the OFF position. Also disconnect power plug and cable.
