Your Carrier Transicold refrigeration unit has been designed with the safety of theoperator in mind. During normal operation, all moving parts are fully enclosed to helpprevent injury. During all pre--trip inspections, daily inspections, and problemtroubleshooting, you may be exposed to moving parts; please stay clear of thesemoving parts when the unit is in operation and when the main power switch is in theRun (On) position.The evaporator and condenser are made of finned tubes. The fins can cause injury oncontact with skin. It is recommended to wear protective gloves during all handlingoperations.During operation, certain components such as the exhaust pipe, discharge outlet, andcooling circuit radiator can become extremely hot. During routine service operations,wear protective gloves.

AUTO--START/STOP

Your refrigeration unit is equipped with Auto-Start/Stop, a valuable fuel saving feature.When the unit is set for Auto-Start/Stop operation it may start at any time. Whenperforming any check of the refrigeration unit (e.g., checking the belts, checking theoil), make certain that the main power switch is in the OFF (0) position.

ENGINE COOLANT

The engine, as with all diesel engines, is equipped with a pressurized cooling system.Under normal operating conditions, the coolant in the engine and radiator is under highpressure and is very hot. Contact with hot coolant can cause severe burns. Do notremove the cap from a hot radiator; if the cap must be removed, do so very slowly inorder to release the pressure without spraying.

REFRIGERANTS

The refrigerant contained in the refrigeration system of your unit can cause frostbite,severe burns, or blindness when in direct contact with the skinor eyes.For this reason,andbecauseof legislation regarding thehandlingof refrigerants during systemservice,whenever your unit requires service of the refrigeration system, we recommend thatyou contact your nearest Carrier Transicold authorized repair facility for service.

PRETRIP INSPECTION

13

GB

The pre--trip inspection should be performed before picking up any load. Thisinspection is essential to anticipate and help minimize the possibility of“over--the--road” problems. These checks take only a few minutes.

1. Place the unit’s main switch in the STOP (0) position.

2. Fuel -- drain any water and impurities from the sump of the refrigeration unitfuel tank by opening the drain--cock located on the bottom of the tank (if soequipped). Close the valve when only pure fuel emerges. Check the fuel levelin the tank, ensuring that the fuel supply is adequate for unit operation. Refuelif necessary.

3. POLY-V Belts -- Genesis R90U unit is equipped with poly-V belt. It allowshigher power transmission compared to the conventional V-belt but aligmenttolerances are tighter.

4. Battery -- on unit equipped with serviceable batteries, the level of theelectrolyte in each of the cells should be checked. If the level is low, distilledwater should be added to the correct level. Most units, however, areequipped with low or no--maintenance batteries. Check battery connectionsand battery supports.

5. Engine Oil -- the engine oil should be checked last since it is necessary for oilto drain out of the block and into the oil pan to obtain a correct reading.Remove the plug/dip--stick (1), wipe it off and re--insert it fully into the engineblock. Once again, remove the dip--stick and observe the oil level; it shouldbe somewhere between the full and add marks. If it is below the add mark,add oil until the level is correct.

PRETRIP INSPECTION

6. Over--all Unit inspection -- visually inspect the entire unit for leaks, loosebolts, frayed, loose, or broken wires, etc. The radiator and condenser coils ofthe unit should be free of dirt, bugs, cardboard, or any other debris that mayobstruct airflow across the coils. The evaporator (located inside the body)should be free of debris also, especially stretch--wrap, which is often usedduring transport to prevent cargo shifting.

7. Truck body -- The body should be inspected prior to loading. Check the doorand vent seals for damage and wear. Inspect the entire interior and exteriorof the body to detect any damage including in the inner and outer skins of thebody. Damage to the insulation may compromise the unit’s ability to maintainthe product temperature by increasing the amount of heat gain across thetruck body.

PRODUCT LOADING

19

GB

Proper air circulation in the truck body, air that canmove around and through the load,is a critical element in maintaining product quality during transport. If air cannotcirculate completely around the load, hot spots or top--freeze can occur.

The use of pallets is highly recommended. Pallets, when loaded so air can flow freelythrough the pallets to return to the evaporator, help protect the product from heatpassing through the floor of the truck. When using pallets, it is important to refrain fromstacking extra boxes on the floor at the rear of the truck, because this will cut off theairflow.

Product stacking is another important factor in protecting the product. Products thatgenerate heat, fruits and vegetables for example, should be stacked so the air can flowthrough the product to remove the heat; this is called “air stacking” the product.Products that do not create heat, meats and frozen products, should be stacked tightlyin the center of the truck. All products should be kept away from the sidewalls of thebody, allowing air to flow between the body and the load; this prevents heat filteringthrough the walls from affecting the product.

It is important to check the temperature of the product being loaded to ensure that it isat the correct temperature for transport. The refrigeration unit is designed to maintainthe temperature of the product at the temperature at which it was loaded; it was notdesigned to cool a warm product.

OPTIONS FOR INSULATED BODIES

D Mobile partition

The mobile partition must be placed at a minimum distance from the evaporator of 1m for : MTS700 / MTS1100 / MTS1450 / MTS2200

D Ducting of evaporator air outlet

Ventilation ducts must never be covered.

SOME ADVICE

Before loading

D Pre--cool the inside of the insulated body by lowering the temperature for about 15minutes.

D Evacuate the humidity existing inside the box by carrying out amanual defrost. Thiscan only take placewhen enabled by the defrost thermostat (box temperature lowerthan 3_C during pulldown and 8_C during heating).

D Evaporator fans are protected by safety grills. In the event of heavy duty use of theunit, ice can accumulate on the grills. It is therefore recommended to clean themregularly bymeans of a small brush. The operationMUST bedonewhen the unit hasbeen SHUT DOWN.

PRODUCT LOADING

20

When loading

D To be carried out with the unit stopped.

D It is recommended to open doors as little as possible to avoid the intake of hot airand humidity.

D Select the temperature by means of the thermostat, according to the transportedgoods.

D Check the internal temperature of the goods being loaded (using a probethermometer).

D Take care not to obstruct the air intakes on the evaporator section and theventilationducts.

Load spacers

Load on pallets

D Leave a free space of about :- 6 to 8 cm between load and frontwall,

- 20 cm between the top of the load andthe roof,

- between the floor and the load(gratings, pallets).

D Do not forget to close the doors.

D Before closing the doors, check your load once more and see that nobody is shutinside the box.

NOTE :

For stationnary utilization, we recommend to place the body in the shade.

IMPORTANTNever leave your unit more than amonth without running.

RECOMMENDED TRANSPORTTEMPERATURES
