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 notices are presented in 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, should never go unattended. Always obtain first aid or medical attention 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.

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 sure power is turned off before working on motors, controllers, solenoid valves and electrical control 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 arc welding on the unit or container, disconnect all wire harness connectors from the 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 CO2 (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 severe 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 highly corrosive and toxic compounds.

WARNING

Be sure to avoid refrigerant coming in contact with the eyes. Should 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.

SECTION 1

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 using a 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 front of 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 are dual voltage units designed to operate on 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 autotransformer is 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 microprocessor-based controller and a integrated 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 will operate automatically to maintain the desired temperature within very close limits. The control system automatically selects cooling, holding or heating as necessary to maintain the desired temperature within the container.

WARNING

Beware of unannounced starting of the evaporator and condenser fans. Do not open the condenser fan grille before turning power OFF and disconnecting 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.

SECTION 2

DESCRIPTION

2.1 GENERAL DESCRIPTION

a. Refrigeration Unit -- Front Section

The front section of the refrigeration unit shows access to most parts of the unit (i.e., compressor, condenser, receiver, etc.), which will be discussed in more detail of the following sections in 2.1. The upper access panels

allow front entry into the evaporator section, and the center access panel allows access to the thermostatic expansion valve and evaporator coil heaters. The unit model number, serial number and parts identification number will be found on the front of the unit to the left of the compressor.

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.

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 the air through the bottom of the refrigeration unit into the container.

When transporting perishable (chilled) commodities, the fan motors will normally be in high speed above -10_C (+14_F), or -5_C (+23_F) optionally.

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.

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.
