FIRST AID AND SAFETY


REFRIGERANTEYESImmediately flush eyes with large amounts of water and get prompt medical attention.SKINFlush area with large amounts of warm water. Do not apply heat. Wrap burns with dry, sterile, bulky dressing to protect from infection/injury and get medical attention.INHALATIONMove victim to a fresh air location and restore breathing if necessary. Stay with them until the arrival of emergency medical personnel.

REFRIGERANT OILEYESImmediately flush eyes with large amounts of water for at least 15 minutes while holding the eyelids open. Get prompt medical attention.SKINRemove any contaminated clothing. Wash thoroughly with soap and water. Get medical attention if irritation persists.INHALATIONMove victim to a fresh air location and restore breathing if necessary. Stay with them until arrival of emergency personnel.

INGESTIONDo not induce vomiting. Contact local poison control centre or physician immediately.

REFRIGERANT INFORMATIONAlways observe caution when working with refrigerants and in areas where they are being used.Fluorocarbon refrigerants evaporate rapidly, freezing anything that they come in contact with if accidentally released to the atmosphere from their liquid state.Refrigerants may produce toxic gases which, in the presence of an open flame or electrical short, can become severe respiratory irritants which can be fatal.Refrigerants displace air and can cause oxygen depletion which could result in death by suffocation. Observe caution at all times when working with or around refrigerant, or air conditioning systems which contain refrigerant, especially in enclosed or confined areas.

SAFETY PRECAUTIONSThermo King recommends all services be performed by a Thermo King dealer. However, there are several general safety practices which you should be aware of:1. Always wear safety glasses when working

with or around the refrigeration system or battery.Refrigerant or battery acid can cause permanent damage if it comes in contact with your eyes.

2. Never operate the unit with the compressor discharge valve closed.

3. Always keep your hands and loose clothing clear of fans and belts when unit is running or when opening or closing compressor service valves.

4. Always use extreme caution if you ever have occasion to drill holes in your unit. This could weaken structural components. Drilling into electrical wiring or refrigerant lines could cause a fire.

5. All service work on evaporator or condenser coils be completed by a certified Thermo King technician. If you ever do have occasion to be working around the coils, use extreme caution as exposed coil fins could cause painful lacerations.

RECOVER REFRIGERANT

At Thermo King we recognize the need to preserve the environment and limit the potential harm to the ozone layer that can result from allowing refrigerant to escape into the atmosphere. We strictly adhere to a policy that promotes the recovery and limits the loss of refrigerant into the atmosphere.

ELECTRIC STANDBYOn Model 50 units, the unit may start automatically at any time when the unit is switched on, connected to live electric power and/or the Electric operation is selected.Be sure to switch the unit off before opening the doors or inspecting any part of the unit.

ELECTRICAL HAZARDUnits with electric operation or electric standby present a potential electrical hazard. Always disconnect the high voltage power cable before working on the unit.

SL-400e with SR-2 ControllerWARNING!

Electric welding generates high amperage currents which can damage electrical and electronic components. To minimize damage, prior to any welding operation on the vehicle, the microprocessor and unit battery must be electrically disconnected from the vehicle. Switch the Microprocessor On/Off switch to Off. Remove the negative battery cable. Remove all connectors from the rear of the microprocessor. Close the control box. Connect the welder ground cable as close as possible to the area being welded. When welding is completed, remove the welder ground cable. Reconnect the cables to the rear of the microprocessor. Reattach the negative battery cable. Switch the microprocessor On/Off switch to On. Reset all alarms and codes to previous settings. Run a full Pretrip. A detailed procedure may be found in Thermo King Service Procedure A26A.

WARNINGSL-400e with Smart Reefer 2 (SR-2) Controller

This unit is capable of automatic operation and could start at any time. The microprocessor on/off switch must be placed in the Off position ("0") before: any inspection, maintenance or service operation is performed on the unitthe unit is placed in a location where a start-up would be undesirable (for example, a confined area).

The microprocessor on/off switch supplies or removes electrical power to the microprocessor. It is located between the communication ports on the left side of the Smart Reefer 2 control panel (1).

UNIT DESCRIPTION

UNIT DESCRIPTION

GENERAL INFORMATIONThe Thermo King SL models are one piece, self-contained, diesel powered cooling/ heating units operating under the control of a programmable microprocessor controller. The units mount on the front of the trailer with the evaporator extending through an opening in the front wall.There are several models:• SL-100e, SL-200e and SL-400e Model 30:

Cooling and heating on diesel engine operation.

• SL-100e, SL-200e and SL-400e Model 50: Cooling and heating on diesel engine or electric motor operation.

• Spectrum SL 30: Multiple trailer compartment cooling and heating on diesel engine operation

• Spectrum SL 50: Multiple trailer compartment cooling and heating on diesel or electric motor operation.

Power is provided by a 4-cylinder, water-cooled, direct injection diesel engine. The engine is coupled directly to the compressor. Belts convey power to the unit fans, alternator and water pump.

During diesel engine operation, the unit will operate in one of the following modes depending on the air temperature in the trailer, as sensed by the microprocessor controller:Continuous Run Operation• High Speed Cool• Low Speed Cool• Low Speed Modulated Cool (if equipped

with Modulation)• Low Speed Modulated Heat (if equipped

with Modulation)• Low Speed Heat• High Speed Heat• DefrostCYCLE-SENTRY Operation (Optional)• High Speed Cool• Low Speed Cool• Null (Engine Off)• Low Speed Heat• High Speed Heat• DefrostGenerally, the unit will operate in low speed, switching back and forth from cooling to heating as necessary.On very hot days, with the setpoint at a low temperature, the unit may cycle between high speed cool and low speed cool without switching into a heating cycle.

Likewise, on very cold days, the unit may cycle between high speed heat and low speed heat. The unit may switch into cooling for short periods of time.The electric motor on Model 50 units is an 11.7 hp, 1450 RPM induction motor operating on 220/380 volt, 3 phase, 50 hertz power. The electric motor powers the compressor through a belt and clutch system.During Standby electric operation, the Model 50 units operate in one of the following modes to maintain the trailer temperature:• Cool• Motor Off• Heat• Defrost

THERMO KING COMPRESSORSSL-400e and Spectrum SL units feature the Thermo King X430, 4-cylinder compressor with 492 cc displacement.The SL-100e and SL-200e feature the X426 4-cylinder compressor with 423 cc displacement.

UNIT DESCRIPTION

THERMO KING CONTROLLERSYour SL unit uses one of the following control systems to operate cooling, heating, and defrost functions. The operation and features of each are discussed in separate sections of this manual. Please note the controller type on your Thermo King unit and refer to the appropriate controller sections for controller description and unit operation.Using the latest in digital technology, the Thermoguard Microprocessor Controller regulates all unit functions. It incorporates thermostat, thermometer, mode and operating data displays, alarm functions and automatic defrost control into one self-contained package.

CONTROLLER SYSTEMS:

Note The earlier version of the µP-IV Multiple Compartment Controller said “MULTI-TEMP µP-IV” instead of “SMART REEFER” on the top. The earlier version of the µP-VI Controller said “THERMOGUARD µP-VI” instead of “SMART REEFER” on the top.

UNIT DESCRIPTION

CYCLE-SENTRY START/STOP CONTROLSThe CYCLE-SENTRY system automatically starts up the unit when heating or cooling is required and shuts it off when the cargo box temperature reaches the controller setpoint.The CYCLE-SENTRY system also maintains engine temperature by restarting the unit if the engine block temperature drops below -1°C. It runs until the controller demand is satisfied and the engine block temperature reaches 32°C.CYCLE-SENTRY is designed for use only with products which do not require tight temperature control or continuous airflow, such as all deep frozen products and non-perishable non-frozen products.The start/stop nature of CYCLE-SENTRY does not satisfy the temperature control or airflow requirements for perishable or temperature sensitive products. Thermo King therefore does NOT recommend the use of CYCLE-SENTRY control for these products.

DEFROSTAs the unit is operated to cool the trailer, frost will gradually build up on the evaporator coils. Periodically this frost must be melted to prevent loss of cooling and airflow.Defrost is accomplished by passing hot refrigerant gas through the evaporator coils, thus melting the frost (or ice). Melted frost drains out of the unit onto the ground through the drain tubes. The defrost damper closes during defrost to prevent warm air from entering the cargo area.

MODULATIONSystems equipped with modulation can provide precise temperature control of fresh products. This can reduce product dehydration, increase product shelf life and protect fresh products from freeze damage.As the return air temperature falls toward setpoint, the unit closes a modulation valve to throttle suction gas returning to the compressor and reduce unit cooling capacity. If additional reduction in cooling capacity is needed, the unit will open a hot gas injection solenoid, injecting hot gas directly into the evaporator coil.

WARNING!Set the unit On/Off switch to OFF before opening doors or inspecting any part of the unit. With the Continuous/Cycle switch in the CYCLE position, and the unit On/Off switch in the ON position, the unit may start at any time without warning.

CARE AND MAINTENANCE


PRE-TRIP INSPECTIONPre-trip inspections are essential to minimize operating problems and breakdowns, and must be performed before every trip involving refrigerated cargo.1. Diesel FuelMust guarantee engine operation to the next check point.2. Engine OilShould be at the FULL mark. Never overfill.3. CoolantThe indicator should be in the FULL (white) range. If the coolant level is in the ADD (red) range, add coolant to the expansion tank. Coolant should be a 50/50 mixture of ethylene glycol and water to provide protection to -34°C.4. BatteryThe terminals must be tight and free of all corrosion. Electrolyte should be at full mark.5. BeltsThe belts must be in good condition and adjusted to the proper tension. Allow 13 mm deflection at the centre of the span between pulleys.

6. ElectricalEnsure all electrical connections are securely fastened. Wires and terminals should be free of corrosion, cracks or moisture.7. StructuralVisually inspect the unit for leaks, loose or broken parts and other damage.8. GasketThe unit mounting gasket should be tightly compressed and in good condition.9. CoilsEnsure condenser and evaporator coils are clean and free of debris.10. Cargo BoxInspect the interior and exterior of the trailer for damage. Any damage to the walls or insulation must be repaired.11. DamperThe damper in the evaporator air outlet must move freely with no sticking or binding.12. Defrost DrainsCheck the defrost drain hoses and fittings to ensure they are open.13. DoorsEnsure doors and weather seals are in good condition, doors latch securely and weather seals fit tightly.

LOADING

GENERAL INFORMATION1. Inspect the trailer for proper insulation.2. Ensure all door seals are tight seal with no air

leakage.3. Inspect the trailer inside and out for damaged

or loose doors or skin.4. On the inside, look for damaged walls, air

ducts, floor channels or “T” flooring, clogged defrost drain tubes and clogged or damaged floor channels which could block the air return, creating “Hot Spots” in the load.

5. Pre-cool the trailer as required.6. Ensure loads are at proper carrying

temperature when you pick them up. Note any variance.

7. Supervise loading of the product to assure sufficient air space around and through the load so as not to restrict air flow.

CAUTION!Do not remove the expansion tank cap while the coolant is hot.

28


INSPECTING THE LOADAlways inspect load prior to departure.1. Ensure unit is off before opening the trailer

doors. Otherwise refrigerated air is expelled hot air drawn in. The unit may be run with the doors open if the trailer is properly backed into a refrigerated warehouse.

2. Perform final external and internal load temperature checks. Note any irregularities on the manifest.

3. Ensure cargo is not blocking the evaporator inlets and outlets and that ample circulation space has been provided around the load.

4. Ensure trailer doors are securely locked.5. Ensure controller setpoint is at the desired

temperature.6. If the unit was stopped, restart using the

starting procedures outlined in this manual.7. Repeat the After Start Inspection.8. Defrost the unit one half-hour after loading

by selecting the Manual Defrost. The Defrost cycle terminates automatically.

INSPECTIONS DURING OPERATION1. Carry out an inspection every four hours

while a loaded trailer is either parked or in transit.

2. Note controller setpoint to ensure setting is unaltered since picking up the load.

3. Note the return air temperature, it should be +/- 4°C of the controller setpoint. If the temperature reading is not +/- 4°C of the controller setpoint, keep the unit running for 15 minutes and re-check the temperature. Wait 15 minutes more and if the temperature is still out of range, contact a Thermo King dealer for service.

4. We recommend you record the return air temperature reading each time you check the unit. This is important information if you need service later on.

Notes: If cargo temperature is too high it could indicate:• Evaporator is plugged with frost in which

case standard defrosting procedure is needed or there is improper air circulation within the cargo area.Inspect the unit to determine if the evaporator fan is working and circulating the usual amount of air. Poor circulation could be caused by:– Fan belt slipping or damaged. (Have the

fan belt checked by a qualified mechanic.)– Defrost damper damaged and stuck in

closed position.– Improper loading of product in trailer or

load shifting in transit so that there are restricted air passages around and through the load.

– Unit may have a low refrigerant charge. If you cannot see a liquid level in receiver tank sight glass with the unit running in COOL, it is an indication that the charge may be low.

It is advisable that any of the above mentioned problems found during your enroute inspection be referred to the nearest authorized Thermo King dealer as quickly as possible. Check your service directory for phone number and location.
