SAFETY

Your Carrier Transicold refrigeration unit has been designed withthe safety of the operator in mind. During all pre-trip inspections,daily inspections, and problem troubleshooting, you may beexposed to moving parts; please stay clear of all moving parts whenthe unit is in operation and when the Start/Run-Off Switch is in theSTART/RUN position.

AUTO-STARTYour refrigeration unit is equipped with Auto-Start in both Start/Stopand Continuous Run modes. The unit may start at any time, abuzzer will sound for 5 seconds before the unit is started. Whenperforming any check of the refrigeration unit (e.g., checking thebelts, checking the oil), make certain that the Start/Run-Off Switchis in the OFF position.

ENGINE COOLANTThe engine is equipped with a pressurized cooling system. Undernormal operating conditions, the coolant in the engine and radiatoris under high pressure and is very hot. Contact with hot coolant cancause severe burns. Do not remove the cap from a hot radiator; ifthe cap must be removed, do so very slowly in order to release thepressure without spray.

REFRIGERANTSThe refrigerant contained in the refrigeration system of your unitcan cause frostbite, severe burns, or blindness when in directcontact with the skin or eyes. For this reason, and because oflegislation regarding the handling of refrigerants during systemservice, we recommend that, whenever your unit requires serviceof the refrigeration system, you contact your nearest CarrierTransicold authorized repair facility for service.

BATTERYThis unit is equipped with a lead-acid type battery. The batterynormally vents small amounts of flammable hydrogen gas. Do notsmoke when checking the battery. A battery explosion can causeserious physical harm and/or blindness.

262--10601

SELF TEST

5 62--10601

The microprocessor controller will run a self test. All of the modelights will light, all of the segments on the display will be turned on.

The display will then show the setpoint temperature on the left andthe box temperature of the trailer on the right. The last character(after the degree symbol) shows the temperature units as F(Fahrenheit) or C (Celsius).

If the unit is in Auto Start/Stop mode or Continuous Run/AutoOperation mode, the glow plugs will energize, the buzzer willsound, and the diesel engine will start.

If the unit is set for Continuous Run/Manual Operation mode, theunit must be started manually.

WARNINGUnder no circumstances should ether or any otherstarting aids be used to start engine.

The microprocessor controller monitors box temperature, batteryvoltage, and engine coolant temperature. Once the setpoint isreached the controller will shut off the diesel engine to conservefuel. The controller will not shut off the engine if the battery voltageis not sufficient to restart it.

The controller will restart the engine if any of the following criteriahave been met:

SBox temperature has changed by ¦ 11°F (¦ 6.1°C)for setpointsin the perishable range and +11° F (+6.1°C) for setpoints in thefrozen range DURING minimum off time.

SBox temperature has moved away from setpoint by ¦3.6°F(2.0°C) AFTER minimum off time for setpoints in the perishablerange or +3.6°F (2.0°C) for setpoints in the frozen range.

SThe battery voltage drops below 11 Vdc (12.2 Vdc for units withEEPROM Rev 3.25 and higher -- Refer to Page 21 for unit data).

SThe engine coolant temperature drops below 34°F (1°C).

1. Press the AUTO S/S-CONTINUOUStoggle key until START-STOP isdisplayed. Unit is now in AutomaticStart/Stop mode.

START/STOP

Automatic start/stop is provided to permit starting/restarting of thediesel-driven compressor as required. This gives themicroprocessor automatic control of starting and stopping thediesel engine. The main function of automatic start-stop is to turnoff the refrigeration system near the setpoint to provide a fuelefficient temperature control system and then restart the enginewhen needed. Start-Stop operation is normally used for frozenloads. Refer to RECOMMENDED TRANSPORT TEMPERATURES (See Page32).

13 62--10601

The unit will remain in low speed after engine start-up - 5 minutesfor XT products, 10 minutes for all others. If the unit fails to start,shuts down on a safety, or fails to run for the minimum run time,three consecutive times, the fault light is on.

Low speed Start--up for low coolant temperatures is available onConfiguration 7 for all units except those with EEPROM REV 3.23and 3.24 -- Refer to Page 21 for unit data.

The microprocessor controller monitors box temperature, batteryvoltage, and engine coolant temperature.

Whenever the unit starts in Start--Stop, it will run until:

SIt has run for the predetermined minimum run time.

SThe engine coolant temperature is above 122°F (50°C)

SThe box temperature is at setpoint.

The controller will not shut off the engine if the battery voltage is notsufficient to restart it. Battery voltage above approximately 13.4volts is required for shutdown. This varies depending on ambient.Look at battery voltage in data list to find out whether shutdownvoltage has been reached. If there is a “+” in front of the number,the voltage is enough to shutdown and restart. If only the numberappears, the voltage is still too low for shutdown.

The controller will restart the engine if any of the following criteriahave been met:

SBox temperature has changed by ¦ 11°F (¦ 6.1°C)for setpointsin the perishable range and +11° F (+6.1°C) for setpoints in thefrozen range DURING minimum off time.

SBox temperature has moved away from setpoint by ¦3.6°F(2.0°C) AFTER minimum off time for setpoints in the perishablerange or +0.5°F (0.3°C) for setpoints in the frozen range.

SThe battery voltage drops below 11 Vdc (12.2 Vdc for units withEEPROM Rev 3.25 and higher -- Refer to Page 21 for unit data).

SThe engine coolant temperature drops below 34°F (1°C).

NOTE: Defrost cannot be started when the EvaporatorCoil temperature is above 40°F (4.4°C ).

17 62--10601

The defrost mode may be initiated in three different ways if theevaporator coil is below 40°F (4.4°C):

1. Defrost is initiated automatically at preset intervals by thedefrost timer in the microprocessor.

2. Defrost is initiated by the defrost air switch.

3. The defrost mode may be manually initiated by pressing theManual Defrost Key.

The defrost mode terminates when the evaporator temperature ishigher than 55°F (12.8°C). Should the defrost cycle not completewithin 45 minutes, the defrost cycle is terminated.

After the 45 minute termination, the controller will wait 1.5 hoursbefore attempting another defrost cycle. Pressing the manualdefrost key will override this mode and start a defrost cycle.

If a shutdown alarm occurs, defrost will be terminated.

PRE-TRIP INSPECTION

The pre-trip inspection should be performed before picking up anyload. This inspection is essential to anticipate andhelp minimize thepossibility of “over-the-road” problems. These checks take only afew minutes.

1. Place the unit’s main switch in the STOP (0) position.

2. Fuel - drain any water and impurities from the sump of therefrigeration unit fuel tank by opening the drain-cock located onthe bottom of the tank (if so equipped). Close the valve whenonly pure fuel emerges. Check the fuel level in the tank,ensuring that the fuel supply is adequate for unit operation.Refuel if necessary. Dispose of fuel properly. Don’t drain wastefuel onto ground.

3. Belts - Check the belt tension by depressing the belt with yourthumb, near the center of the longest free run of each belt.Under moderate pressure each belt should deflectapproximately 1/4 inch to 1/2 inch (5 mm to 15mm). If the beltsdeflect more than this they should be tightened (loose belts mayslip, generating heat and reducing belt life). If the belts are tootight they should be loosened; tight belts can reduce bearinglife.

4. Battery - on unit equipped with serviceable batteries, the levelof the electrolyte in each of the cells should be checked. If thelevel is low, distilled water should be added to the correct level.Most units, however, are equipped with low or no-maintenancebatteries; these should be inspected to ensure that theconnections are clean and tight, and the battery hold-downshould be checked for tightness.

5. Engine Oil - the engine oil should be checked last since it isnecessary for oil to drain out of the block and into the oil pan toobtain a correct reading. Unscrew and remove the dipstick.Wipe the dipstick clean and insert it into the oil fill tube withoutthreading it all the way back into the tube. Remove the dipstickagain and check oil level. DO NOT add oil if the level is in the“safe” range. If needed, add oil as indicated by markings ondipstick until level is in the “safe” range. (See page 35).

29 62--10601

6. Over-all Unit - visually inspect the entire unit for leaks, loosebolts, frayed, loose, or broken wires, etc. Theradiator/condenser coils of the unit should be free of dirt, bugs,cardboard, or any other debris that may obstruct airflow acrossthe coils. The evaporator (located inside the trailer) should befree of debris also, especially stretch-wrap, which is often usedduring transport to prevent cargo shifting.

7. Start a Pretrip Check (See Page 8). The unit will cycle thru allmodes of operation at 30 second intervals, and return to normaloperation when complete. Monitor Pretrip and watch/listen forunusual operation or noises.

3062--10601

PRODUCT LOADING

BEFORE LOADING:

D Pre-cool the trailer. This will remove much of the heat from theinside of the trailer, and give the product better protection whenit is loaded.

D If possible, place the unit in a defrost cycle immediately beforeloading. This will remove moisture accumulated on theevaporator coil.

DURING LOADING:

D Turn the unit off!

D Check product temperature during loading.

D Ensure that the air return and supply opening remainunobstructed.

D Leave approximately 4 to 5 inches (10 to 12 cm) between theload and the front wall for air return to the unit.

D Leave at least 10 to 12 inches (25 to 30 cm) between the top ofthe load and the ceiling to ensure that there is nothing to preventairflow to the rear of the body

D Load product on pallets to provide free air return to unit andimprove product protection.

Proper air circulation in the trailer, air that can move around andthrough the load, is a critical element in maintaining product qualityduring transport. If air cannot circulate completely around the load,hot spots or top-freeze can occur.

The use of pallets is highly recommended. Pallets, when loaded soair can flow freely through the pallets to return to the evaporator, helpprotect the product from heat passing through the floor of the trailer.When using pallets, it is important to refrain from stacking extra boxeson the floor at the rear of the trailer, this will cut off the airflow.

31 62--10601

Product stacking is another important factor in protecting theproduct. Products that generate heat - fruits and vegetables, forexample - should be stacked so the air can flow through the productto remove the heat; this is called “air stacking” the product.Products that do not create heat - meats and frozen products -should be stacked tightly in the center of the trailer. All productsshould be kept away from the side-walls of the body, to allow air flowbetween the body and the load; this prevents heat filtering throughthe walls from affecting the product.

It is important to check the temperature of the product being loadedto ensure that it is at the correct temperature for transport. Therefrigeration unit is designed to maintain the temperature of theproduct at the temperature at which it was loaded; it was notdesigned to cool warm product.

3262--10601

RECOMMENDED TRANSPORT TEMPERATURES
