When using a refrigeration system it is wise to follow some simple guidelines to ensure that you get the best from your system. These simple things will ensure that your products stay at the correct temperature:

• Pre-cool the refrigerated compartment prior to use
• Ensure the product is loaded at the correct temperature (the refrigeration system is designed to maintain the loaded temperature. If you want to deliver goods at 3ºC then make sure they are at 3ºC when loaded)
• Do not run the unit on engine or standby whilst loading the refrigerated compartment
• Keep the door opening times to a minimum
• Keep the engine running if it is safe (and legal) to do so
• Do not restrict air circulation around the load or the evaporator
• Keep the strip curtains in their correct position if fitted
• Carry out a manual defrost during the last return journey of each day
• Do not use leads that are in a poor condition i.e. showing exposed wires, or broken plug or sockets
• Do not plug a live lead into the refrigeration system, it can cause damage
