SAFETYYour Carrier Transicold refrigeration unit has been designed with thesafety of the operator in mind. During normal operation, all movingparts are fully enclosed to help prevent injury. During all pre--tripinspections, daily inspections, and problem troubleshooting, youmay be exposed to moving parts; please stay clear of these movingparts when the unit is in operation and when the main power switchis in the Run (On) position.The evaporator and condenser are made of finned tubes. The finscan cause injury on contact with skin. It is recommended to wearprotective gloves during all handling operations.During operation, certain components such as the exhaust pipe,discharge outlet, and cooling circuit radiator can become extremelyhot. During routine service operations, wear protective gloves.AUTO-- START/STOPYour refrigeration unit is equipped with Auto-Start/Stop, a valuablefuel saving feature. When the unit is set for Auto-Start/Stopoperation it may start at any time. When performing any check ofthe refrigeration unit (e.g., checking the belts, checking the oil),make certain that the main power switch is in the OFF (0) position.ENGINE COOLANTThe engine, as with all diesel engines, is equipped with apressurized cooling system. Under normal operating conditions, thecoolant in the engine and radiator is under high pressure and is veryhot. Contact with hot coolant can cause severe burns. Do notremove the cap from a hot radiator; if the cap must be removed, doso very slowly in order to release the pressure without spraying.REFRIGERANTSThe refrigerant contained in the refrigeration system of your unit cancause frostbite, severe burns, or blindness when in direct contactwith the skin or eyes. For this reason, and because of legislationregarding the handling of refrigerants during system service,whenever your unit requires service of the refrigeration system, werecommend that you contact your nearest Carrier Transicoldauthorized repair facility for service.8

SAFETYBATTERYThis unit is equipped with a lead--acid type battery. The batterynormally vents small amounts of flammable hydrogen gas. Keepany flame, any lighted object (cigarette etc.) or any source of sparksaway from the battery elements. A battery explosion can causeserious physical harm and/or blindness.AUTOMATIC START UP IN DIESELWHEN LOSS OF STANDBYFROM EPROM 4.05To activate this function: TIME STRT set up in functionnalparameters.When the unit is started in standby, the “ROAD” light is flashingand the “STANDBY” light is lit.After 5 minutes of loss of power, the unit automaticallystarts in diesel. 5 minutes after the power comes back, the unitstarts again automatically in electric mode. The “STANDBYMOTOR” alarm appears, alarm that you would have to clear.* This function will be active even after a stop (OFF) of the unit.To deactivate it: set up TEMP STRT in functionnal parameters.DEACTIVATE THIS FUNCTION WHEN UNIT ISRUNNING IN A CLOSED AREA !9GB

FEATURESThis refrigeration unit is equipped with a wide range of features thatare designed to improve reliability and temperature control withinthe body.The group can be delivered fitted with a microprocessor controller.MICROPROCESSOR CONTROLS17.1.16.2.15.3.14.4.13.5.12.11.6.7.8.9.1.

FEATURESThe microprocessor controls incorporated into this unit are the mostreliable control system available. It is also designed to be the easiestto use, offering great flexibility in control, yet minimal user input fornormal operation: a true “set it and forget it” design.1. Display window: shows set--point, box temperature, operatingmode, alarm displays, as well as data on the unit itself (batteryvoltage, water temperature etc.).Function Change keyThe function change key is used to display theoperating parameters. Each time this key is pressedthe display will advance to the next parameter. Thiskey, in conjunction with the up/down arrow and enterkeys, will allow the user to change the parameters.Arrows keyThe UP ARROW and DOWN ARROW keys areused to alter the set--point. Press the up or downarrow keys until the desired setpoint is displayed onthe left--hand side of the display window. When thecorrect set--point is displayed, press the ENTER keyto confirm the setting.The UP ARROW and DOWN ARROW keys are alsoused to change the unit functions and scroll throughthe FUNCTION and UNIT DATA screens.Enter keyThe ENTER key confirms changes made to unitoperation. It must be pressed to change the setpointafter using the arrow keys to adjust it. If the ENTERkey is not pressed, the setpoint will revert to thepreviously entered setting.The ENTER key must also be pressed whenever aFUNCTION setting is being altered. If this key is notpressed, the function will revert to its previoussetting.11GB

FEATURESRUN/STOP switchThe main unit RUN/STOP switch controls the unitoperation. When switched to the Run (I) position, theunit will start in the operating mode last entered(Road or Standby). The set--point will be at the lastset--point entered on the keypad.Road keyThe ROAD key puts the unit into Road (or engine)operation when the unit has been previouslyoperated in the Standby mode.City Speed keyThe CITY SPEED key toggles the unit between highspeed and low speed (diesel mode). When CitySpeed is selected, the unit will run only in low speedexcept during defrost cycles. This feature is useful inareas where noise is restricted.Manual defrost keyThe MANUAL DEFROST key places the unit in adefrost cycle. Under most conditions it is notnecessary to defrost the unit manually as this is doneautomatically with the air switch or the defrost timer.Manual defrost may become necessary due to iceaccumulated on the evaporator coil during frequentdoor openings in humid environments.Buzzer Off keyThe BUZZER OFF key temporarily turns off theFAULT ALARM buzzer. The red light “Fault alarm”remains illuminated on the command cab.12

FEATURESStandby keyThe STANDBY key places the unit in Standby (orelectric) mode when the previous mode of operationhas been Road.Pretrip Check keyThe PRETRIP key initiates a check of all normaloperating modes. The temperature inside the boxmust be below 5EC p 1EC (35EF p 2EF) to start thischeck. Upon initiation, the unit will cycle through alloperating modes at 30 second intervals. The displaywill show “PPPP” at the beginning and will showvarious unit data during the pre--trip cycle. Uponcompletion of the pre--trip cycle the unit will beplaced into the defrost mode.Auto Start/Stop Continuous keyThe AUTO--START/STOP key toggles the unitoperating mode between Auto--Start/Stop andcontinuous run. When the unit is set forAuto--Start/Stop operation, the unit will run until thebox temperature reaches set--point and then cycleoff (after the minimum run time has been met) untilfurther cooling or heating is necessary. When in thecontinuous mode, the unit will cycle between heatand cool as required to maintain the set temperaturein the body. If the setpoint is below -12EC (10EF) theunit will not heat, it will run continuously in low speedcool.13GB

PRETRIP INSPECTIONThe pre--trip inspection should be performed before picking up anyload. This inspection is essential to anticipate and help 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 locatedon the bottom of the tank (if so equipped). Close the valvewhen only pure fuel emerges. Check the fuel level in thetank, ensuring that the fuel supply is adequate for unitoperation. Refuel if necessary.3. Belts -- Check the belt tension by depressing the belt withyour thumb, near the center of the longest free run of eachbelt. Under moderate pressure each belt should deflectapproximately 6 mm to 13 mm (1/4 inch to 1/2 inch). If thebelts deflect more than this they should be tightened (loosebelts may slip, generating heat and reducing belt life). If thebelts are too tight they should be loosened; tight belts canreduce bearing life.4. Battery -- On unit equipped with serviceable batteries, thelevel of the electrolyte in each of the cells should bechecked. If the level is low, distilled water should be addedto the correct level. Most units, however, are equipped withlow or no--maintenance batteries. Check batteryconnections and battery supports.21GB

PRETRIP INSPECTION5. Engine Oil -- The engine oil should be checked last since itis necessary for oil to drain out of the block and into the oilpan to obtain a correct reading. Remove the plug/dip--stick(1), wipe it off and re--insert it fully into the engine block.Once again, remove the dip--stick and observe the oil level;it should be somewhere between the full and add marks. If itis below the add mark, add oil until the level is correct.16. Over--all Unit inspection -- Visually inspect the entire unit forleaks, loose bolts, frayed, loose, or broken wires, etc. Theradiator and condenser coils of the unit should be free ofdirt, bugs, cardboard, or any other debris that may obstructairflow across the coils. The evaporator (located inside thebody) should be free of debris also, especially shrink--wrap,which is often used during transport to prevent cargoshifting.7. Truck body -- The body should be inspected prior to loading.Check the door and vent seals for damage and wear.Inspect the entire interior and exterior of the body to detectany damage including in the inner and outer skins of thebody. Damage to the insulation may compromise the unit’sability to maintain the product temperature by increasing theamount of heat gain across the truck body.22
