Truck/Trailer Refrigeration Unit - Sunbelt Transport Refrigeration

SECTION 2OPERATION2.1 PRE-TRIP INSPECTIONa. Before Starting Engine1. Drain water and sediment from fuel tank sump.Fill tank with diesel fuel.2. Check radiator coolant level. (Add pre-mixed50/50 permanent antifreeze-water as required.) USEETHYLENE GLYCOL ONLY. (Refer to Section 1.2)3. Check evaporator and condenser coil forcleanliness.4. Check engine lubrication and fuelfilter, oillines,and connections for leaks. (Tighten connections and/orreplace gaskets.)5. Check engine oil level. (Refer to Section 1.2)6. Check V-belts for proper tension, fraying orcracks. Adjust belts or replace.WARNINGInspect battery cables for signs of wear, abrasionor damage at every Pre---Trip inspectionand replace if necessary. Also checkbattery cable routing to ensure that clampsare secure and that cables are not pinchedor chafing against any components.7. Check battery terminals for cleanliness andtightness. Clean and coat with a mineraltype grease (suchas Vaseline).8. Check engine air cleaner for cleanliness andcondition of air cleaner hose.9. Check defrost drain pan hoses. (Should be clearof debris.)b. After Starting Refrigeration Unit1. Check water temperature. (Should be 65 to82_C = 150 to 180_F.)2. Check engine speed. (Refer to Section 4.4.3.)3. Listen for abnormal noises. (Refer to Section3.3.7)4. Check compressor oil level. (Refer to Section4.13)5. Observe any signs of lube or fuel oil leaks.6. Check radiator hoses for leaks.7. Check refrigerant level. (Refer to section 4.10)8. Feel filter-drier. Excessive temperature dropacross drier indicates restriction. (Refer to section 4.15)2.2 STARTING AND STOPPING INSTRUCTIONS-- ENGINE DRIVEWARNINGUndernocircumstancesshouldetheroranyother starting aids be used to start engine.WARNINGBeware of unannounced starting of fans andV-belts caused by thermostatic cycling.NOTEWhenever starting the truck unit engine, inorder to reduce starter cranking and engineloads, the microprocessor always starts andoperates in low speed, unloaded cool for the first15 seconds. After first 15 seconds themicroprocessor will allow the unit to operatenormally, providing the coolant temperature isabove 26_C (79_F). In order to prolong enginelife, the microprocessor will prevent operation inhigh speed until coolant temperature reachesthis temperature.2.2.1 AUTOMATIC STARTa. Starting Instructions1. Place the Run-Stop Switch in the RUN position.2. For truck units, place the On-Off Switch (CabCommand) to ON position and press the Road Key.3. The microprocessor will perform a self-test (alldisplay messages will appear in display window). Next,setpoint and box temperature will be displayed. Themicroprocessor will energize glow cycle (length of timedepends on engine temperature) and start the engine.4. To change the setpoint, press the Up Or DownArrow Key and then the Enter Key.5. Pressing the Auto S/S---Continuous Key changesthe operation of the unit between automatic start/stop(unit will automatically start and stop in response tochanging box temperature) or automatic start continuousrun (unit will operate continuously after starting).b. Stopping InstructionsPlace the On-Off Switch (Cab Command if used) toOFF position or place Run-Stop Switch in the STOPposition to stop unit.Change 05/102-1 62-02884
