7. Installation Procedure
After delivery, allow the unit to stand for 12 hours before operation, in order to let the compressor oil settle.
Before using the unit for the first time clean the shelves and freezer cavity with soapy water. ONLY USE DISH WASHING SOAP.
Allow the unit to operate EMPTY until the SET TEMPERATURE IS REACHED before introducing a heat load. This allows the compressor to warm up first.
Set the brakes of the roller feet to keep the unit in its intended position.
Maintain a distance of 20cm (7 inches) between the unit and the walls or other objects for ventilation. Increase distance if the object next to the unit produces heat.
