Page 19 Follow safe work practices and utilize the appropriate protective equipment at all times. Your Carrier Transicold refrigeration unit has been designed with the safety of the operator in mind. During normal operation, all moving parts are fully enclosed to help prevent injury. During all pre-trip inspections, daily inspections, and problem troubleshooting, you may be exposed to moving parts.
Page 20: Figure 1.1 Lockout/Tagout
Power Figure 1.1 Lockout/Tagout Be aware of HIGH VOLTAGE supplied at the power plug. Even with the unit off, power is present from the plug to the inside of the control box. Whenever practical, disconnect the high voltage source when performing service or maintenance procedures and lockout/tagout the receptacle in accordance with your company procedures.
Page 21 WARNING Do not connect power plug to any electrical outlet without checking that it meets the 460/3/60 and 30 Amp electrical requirements of the unit. WARNING Ensure the power plug is clean and dry before connecting to any electrical outlet / receptacle. WARNING Do not toggle the START/RUN - OFF switch out of the OFF position when in PC Mode or the unit will start.
Page 22 WARNING Only a refrigerant cylinder containing R404A should be connected to this refrigeration unit in order to pressurize the system. However, dry nitrogen may be used to increase pressure. Any other gas or vapor will contaminate the system and require additional removal and evacuation. WARNING Do not use a nitrogen cylinder without a pressure regulator.
Page 23 Do not bend the copper tubing on the condenser coil when installing the new condenser. Bend the unit tubing if tubes do not align correctly. Under no circumstances should anyone attempt to repair sealed module internal components. Should a problem develop with these components, contact your nearest Carrier Transicold dealer for replacement. 1–5...

Page 31: Unit Description
2.1. GENERAL DESCRIPTION The Vector 8100 unit is an all electric, fully charged, pre-wired, refrigeration/heating “nose mount” unit. The unit is used on insulated refrigerated compartments to maintain cargo temperatures within very close limits. Electrical power is supplied to the unit from an external source, at the power supply receptacle (PSR).

CONDENSING SECTION The condensing section (see Figure 2.1) consists of the compressor, condenser fans, condenser, economizer, refrigerant controls defrost air switch, piping, wiring, and associated components. 2.3.1 Compressor The unit is fitted with a scroll compressor equipped with suction and discharge service valves and an economizer connection.
Page 36: Economizer Transducer And Sensor
2.3.6 Economizer Transducer and Sensor a. Economizer Outlet Pressure Transducer (ECOP) The ECOP is located in the vapor injection line leaving the economizer. It provides the control system with economizer outlet pressure information to be displayed, recorded in DataLink data, and used to determine the required position of the economizer expansion valve.
Page 37: Evaporator Switches, Transducers And Sensors
It is located in the supply air outlet housing. SYSTEM OPERATING CONTROLS AND COMPONENTS Temperature control is provided by the Carrier Transicold APX™ Control System. Once the system is set at the desired temperature, the unit will operate automatically to maintain the desired temperature within very close limits.

Page 46: Economized Mode
The refrigerant pressure drop caused by the expansion valve is accompanied by a drop in temperature so the low pressure, low temperature liquid that flows into the evaporator tubes is colder than the air that is circulated over the evaporator tubes by the evaporator fan. The evaporator tubes have aluminum fins to increase heat transfer; therefore heat is removed from the air circulated over the evaporator.

When field diagnosis of a Carrier Transicold refrigeration unit determines that an APX main microprocessor is not performing properly and must be replaced the replacement microprocessor must be setup for this unit and customer by entering the required Configurations, Functional Parameters and DataLink data recorder settings.
Page 116: Pre-Replacement Steps
The preferred method for setup of the main microprocessor is to use the display mounted keys or a Data Transfer USB memory device. All required changes, except unit specific and time sensitive data, may be performed using the USB memory device. If a USB is not available the main microprocessor may be setup using TRU-Tech.
Page 117: Main Microprocessor Setup
5.5.3 Main Microprocessor Setup 1. Ensure that the replacement main microprocessor is in place, all wires connected and the negative battery cable is reconnected. 2. Make sure the latest software has been loaded to ensure all modules are compatible. When a module is replaced, software should be upgraded before switching the unit on. This will ensure software compatibility of all modules.
Page 118: Configurations Using Display Mounted Keys
NOTES 1. If a Data Transfer USB memory device will be used to setup the remainder of the main microprocessor set- tings, proceed to Section 5.5.7 after the settings are entered. 2.

Page 236 b. Checking For Noncondensibles 1. Install a manifold gauge set to allow reading of suction and discharge pressure. See Figure 8.4. 2. Stabilize system to equalize pressure between the suction and discharge side of the system. The refrigerant system needs to be off for several hours. 3.
Page 237 7. Frontseat (close by turning clockwise) the discharge service valve and the refrigerant will be trapped between the compressor discharge service valve and the liquid line service valve. 8. Before opening up any part of the low side of the system, a slight positive pressure should be indicated on the pressure gauge.
Page 238: Leak Checking
g. Adding a Complete Charge 1. Evacuate unit and leave in deep vacuum. (Refer to Section 8.5.4.) 2. Determine charge required for this unit (refer to the model/serial number nameplate or Table 2–1) and procure a refrigerant cylinder with sufficient weight of refrigerant. Place cylinder on scale and connect charging line from cylinder to liquid line service valve.
Page 239 WARNING Only a refrigerant cylinder containing R404A should be connected to this refrigeration unit in order to pressurize the system. However, dry nitrogen may be used to increase pressure. Any other gas or vapor will contaminate the system and require additional removal and evacuation. Do not vapor charge R404A.
Page 240 3. Ensure that the operator message panel displays “RECOVER/LEAK CHK/EVAC MODE” during the pressurizing and leak checking procedures. (Refer to Section 5.2.5.) If the control system switches to Charge Mode during the process, switch it back to the “RECOVER/LEAK CHK/EVAC MODE”. 4.

Page 243: Figure 8.5 Compressor Kit
COMPRESSOR SERVICE WARNING Before removal of the compressor, relieve the internal pressure by very carefully loosening the couplings to break the seal. The scroll compressor achieves low suction pressure very quickly. Do not use the compressor to evacuate the system below 0 psig. Never operate the compressor with the suction or discharge service valves closed (frontseated).

8.8.14 Temperature Sensor Checkout An accurate ohmmeter must be used to check resistance values shown in Table 8–3 Table 8–4. Due to variations and inaccuracies in ohmmeters, thermometers or other test equipment, a reading within 2% of the chart value would indicate a good sensor. If a sensor is bad, the resistance reading will usually be much higher or lower than the resistance values given in the tables.
