SECTION 2OPERATION2.1 PRE-TRIP INSPECTIONa. Before Starting Engine1. Drain water and sediment from fuel tank sump. Thenfill tank with diesel fuel. (Refer to section 1.2)2. Check radiator coolant level. (Add pre-mixed 50/50permanent antifreeze-water as required.) USEETHYLENE GLYCOL ONLY. (Refer to section1.2)3. Check evaporator and condenser coil for cleanliness.4. Check engine lubrication and fuel filter, oil lines, andconnections 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 or cracks.Adjust belt or replace.7. Check battery terminals for cleanliness andtightness. Clean and coat with a mineral type grease(such as Vaseline).8. Check condenser/evaporator fan shaft bearing forexcessive play.9. Check engine air cleaner for cleanliness andcondition of air cleaner hose.10. Check oil level in compressor sight glass.11. Check defrost drain pan hoses. (Should be clear ofdebris.)12. Check defrost air switch tubes and connections forbreaks or air leaks.b. After Starting Refrigeration Unit1. Check water temperature. (Should be 160 to 180_F=71to82_C.)2. Check ammeter. (Should indicate +2 to +10 ampsafter start-up.)3. Check engine speed. (Refer to section 4.3.3)4. Listen for abnormal noises. (Refer to section 3.3.7)5. Check compressor oil level. (Refer to section 4.13)6. Observe any signs of lube or fuel oil leaks.7. Check radiator hoses for leaks.8. Check refrigerant level. (Refer to section 4.10.f)9. Feel filter-drier. Excessive temperature drop acrossdrier indicates restriction. (Refer to section 4.16)10. Check clutch/gearbox for excessive noise. On Ultimaclutch is on fanshaft.11. Start microprocessor Pre-trip Inspection. (Refer toSection 1.10.8 )2.2 STARTING AND STOPPING INSTRUCTIONS- ENGINE DRIVEWARNINGUndernocircumstancesshouldetheroranyother starting aids be used to start engine.NOTES1. Whenever starting the engine, in order to reducestarter cranking and engine loads, themicroprocessor always starts and operates in lowspeed, unloaded cool for the first 15 seconds.After first 15 seconds the microprocessor willallow the unit to operate normally, providing thecoolant temperature is above 79_F (26_C). Inorder to prolong engine life, the microprocessorwill prevent operation in high speed untilcoolant temperature reaches this temperature.2. With software 3.11 or higher the unit will remainin low speed for 10 minutes after engine start-upwhen: Auto Start/Stop is at any setpoint orContinuous Run setpoint is below 10_F( --- 12_C).2.2.1 AUTOMATIC STARTa. Starting Instructions1. Place the RUN-STOP switch in the RUN position.The microprocessor will perform a self-test (alldisplay messages will appear in display window).Then setpoint and box temperature will be displayed.2. The microprocessor will energize glow cycle (lengthof time depends on engine temperature). Units withbuzzer will sound for 5 seconds before starting theengine.3. To change the setpoint press the UP or DOWN arrowkey and ENTER key.4. Pressing the AUTO S/S---CONTINUOUS keychanges the operation of the unit between automaticstart/stop (unit will automatically start and stop inresponse to changing box temperature) or automaticstart continuous run (unit will operate continuouslyafter starting).b. Stopping InstructionsPlace RUN-STOP switch in the STOP position to stopunit.2.2.2 MANUAL STARTINGa. Starting Instructions (Manual Starting)1. To start the unit manually, place Run/Stop Switch toRUN position.2. Press the AUTO S/S---CONTINUOUS key (ifnecessary) to erase START/STOP from the display.2-1 62-02461
