10 UNIT OPERATION OPERATING PRINCIPLE Over the road, an open compressor is driven by a 12 VDC electric motor, powered by the 12 VDC alternator and the vehicle battery. The vehicle 12 VDC also powers the evaporator and condenser fans. It is therefore essential to shut-down the unit when the vehicle engine has stopped. On standby, the electric motor of the unit drives a generator which supplies the power necessary to run the evaporator and condenser fans. The control is powered by a transformer installed inside the unit. TEMPERATURE CONTROL As soon as the set-point temperature has been reached, regulation is obtained by the start-up and shut-down of the electric motor. The condenser and evaporator fans shut down during the off cycle. NEVER RUN THE UNIT WITH NO GAS. WHEN THERE IS A LEAK ON THE SUCTION SIDE THERE IS ASORPTION OF HUMIDITY. WHENTHEREISALEAKOFTHEDISCHARGESIDE THERE IS A LOSS OF REFRIGERATION OIL. THIS CAN LEAD TO THE COMPRESSOR SEIZING UP.

17 UNIT MAINTENANCE UNIT MAINTENANCE SCHEDULES Regular servicing is required in order to optimize the service life and reliability of your unit. Service operations are to be carried out according to the following schedule: Kilometres Miles Service A Service G Refrigerant : type R134a Oil type for compressors : Only use the type of oil (POE oil) recommended by Carrier Transicold. Oil analysis : On request we can analyse your compressor oil. To do this, we send a small drum with a label on which you should indicate: - thetypeofcompressor, - the lapse of time or mileage since the last oil change, - the type of Carrier equipment, - the date of initial operation. 51

20 PRODUCT LOADING Proper air circulation in the truck body, i.e. that can move around and through the load, is a critical element in maintaining product quality during transport. If air cannot circulate completely around the load, hot-spots during defrost can occur. The use of packaging which enables air circulation in the lower section is highly recommended, in order to enable the free flow of air and its return to the evaporator. Appropriate packaging helps to protect the products from the heat passing through the floor of the vehicle. Product stacking is another important factor in protecting the product. Those generating heat, such as fruit and vegetables, should be stacked in such a way to allow air to flow around the products, to remove the heat they generate: the process is called air stacking the product. Goods which do not generate heat, such as frozen meat and other frozen food products, should be stacked tightly in the centre of the box. All the products should be kept well away from the sidewalls of the box, enabling air to circulate between the box and the load; this prevents the heat filtering through the sidewalls from damaging the products. It is important to check the temperature of the products during loading to ensure they are at the correct temperature for transport. The refrigeration unit is designed to maintain the temperature of products at the temperature at which it was loaded; it was not designed to refrigerate warm products. A FEW SUGGESTIONS efore loading Pre-cool the inside of the insulated body, by lowering the temperature for about 15 minutes. Remove the humidity inside the box by running a manual defrost cycle. This is only possible when the inside temperature is 3 C or less. 54

21 PRODUCT LOADING Evaporator fans are protected by safety grills. In the event of heavy duty use of the unit, ice can accumulate on the grills. It is therefore recommended to clean them regularly by means of a small brush. The operation MUST be done when the unit has been SHUT DOWN. For loading purposes : Only load when the unit has been shut down. It is recommended to minimise the time when the door is open, to avoid intake of hot air or humidity. Select the temperature in relation to the products transported. Check the core temperature of products during loading (probe thermometer). Take care not to block the air intakes and outlets on the evaporator section. Leave a free space of approximately: - 6 to 8 cm between the load and the frontwall - 20 cm between the top of the load and the roof, - a few centimetres between the floor and the load using gratings or suitable packaging. Do not forget to close the doors. Check your load, and see that nobody is shut inside the box. G Note : For stationnary utilization, we recommend to place the body in the shade. IMPORTANT : Never leave a unit more than one month without operating it. 55

22 RECOMMENDED TRANSPORT TEMPERATURES A few general recommendations on product transport temperatures are given below. The information is for reference purposes only, the set-points required by the shipper or receiver have priority. More detailed information is available from your Carrier Transicold distributor. Product ananas 15 C Set-point range 55 F to60 F Fresh fruit and vegetables Fresh meat and seafood Dairy products +4 C to+6 C +2 C +2 C to+6 C +39 F to+43 F +36 F 36 F to43 F During delivery cycles that include frequent stops and door openings, it is recommended to shut down the unit during the time the box doors are open, in order to limit the accumulation of ice on the evaporator. 56
