It contains basic instructions for thedaily operationof therefrigerationunit as well as safety information,troubleshooting tips, and other information that will help you to de-liver the load in the best possible condition. Please take the time toread the information contained in this booklet and refer to it when-ever you have a question about the operation of your Carrier Tran-sicold Supra refrigeration unit has been engineered to provide long,trouble-free performance when it is properly operated and main-tained. The checks outlined in this guide will help to minimize over-the-road problems.

2 Inaddition, acomprehensive maintenancepro-gram will help to insure that the unit continues to operate a maintenance program will also help to control operatingcosts, increase the unit s working life, and improve guide is intended as an introduction to your unit and to providegeneral assistance when needed. More comprehensive informa-tion canbe foundin theOperation andService MANUAL for your MANUAL can be obtained from your local Carrier having your unit serviced, be sure to specify genuine CarrierTransicold replacement parts for the highest quality and best Carrier Transicold, we are continually working to improve theproducts that we build for our customers. As a result, unit specifica-tions may change without Supra 50 Series unit is identified by a nameplate attached tothe frame near the accumulator. This nameplate identifies thecomplete model number of the unit, the serial number, therefrigerant charge and quantity, and the date the unit was placedin a problem occurs, please refer to the information on this plate,and make a note of the model and serial number before calling forassistance.

3 This information will be needed when you contact atechnician or Carrier Transicold Service Engineer so that he or shemay properly assist Carrier Transicold refrigeration unit has been designed withthe safety of the operator in mind. During normal operation, allmoving parts are fully guarded to help prevent injury. During allpre-trip inspections, daily inspections, and problemtroubleshooting, you may be exposed to moving parts; please stayclear of all moving parts when the unit is in operation and when theunit main power switch is in the RUN 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 and without warning. Whenperforming any check of the refrigeration unit ( , checking thebelts, checking the oil), make certain that the main power switch isin the OFF engine is equipped with a pressurized cooling system.

4 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 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 unit utilizes a lead-acid type battery. The battery normallyvents small amounts of flammable hydrogen gas. Do not smokewhen checking the battery. A battery explosion can cause seriousphysical harm and/or pre-trip inspection should be performed before picking up anyload.

5 This inspectionis essential toanticipateandhelpminimizethepossibilit y of over-the-road problems. These checks take only afew Place the unit s main switch in the STOP (0) Fuel -- drain any water and impurities from the sump of therefrigeration unit fuel tank by opening thedrain-cock locatedonthe 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 if Belts -- Check the belt tension by depressing the belt with yourthumb, near the center of the longest free run of each moderate pressure each belt should deflectapproximately 6 mm to 13mm (1/4 inch to 1/2 inch). If the beltsdeflect more than this they should be tightened (loose beltsmay slip, generating heat and reducingbelt life). If thebelts aretoo tight they should be loosened; tight belts can reducebearing Battery -- on units equipped with serviceable batteries, the levelof the electrolyte in each of the cells should be checked.

6 If thelevel is low, distilled water should be added to the correct units, however, areequippedwithlow or no--maintenancebatteries. These should be inspected to ensure that theconnections are clean and tight, and the battery hold--downshould be checked for ONLYNO WORDING55. Engine Oil -- the engine oil shouldbe checked last since it isnecessary for oil to drain from theblock and into the oil pan to obtaina correct reading. Remove thedipstick, wipe it off and re-insert itfully into the engine block. Onceagain, remove the dip-stick andobserve the oil level; it should besomewhere between the full andadd marks. If it is below the addmark, add oil until the level Over-all Unit -- visually inspect the entire unit for leaks, loosebolts, frayed, loose, or broken wires, etc. The radiator andcondenser 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 body) should befree of debris also, especially stretch-wrap, which is often usedduring transport to prevent cargo Truck body -- The body should be inspected prior to the door and vent seals for damage and wear.

7 Inspectthe entire interior and exterior of the body for damage; checkfor damage to the inner and outer skins of the body. Damageto the insulation may compromise the unit s ability to maintainthe product temperature by increasing the amount of heat gainacross the truck THE UNIT --ROADOPERATIONWARNINGU nder no circumstances should ether or any otherstarting aids be used to start TEMPERATUREAUTO START/STOPIUNIT DATAPRETRIPALARM/FAULTSTANDBYBUZZER OFFMANDEFROSTCITYSPEEDROADFUNCTIONENTERS ETPOINTOi-20 35 F1.
