The technological advances being made today have brought about steadily reducing maintenance requirements for all types of mechanical and electrical devices. The increasing use of sealed unit mechanisms for self-contained and semi self-contained cabinets has removed the necessity of motor lubrication, as well as belt adjustment.
However, there is a need for regular maintenance of some components,
especially the cleaning of the air-cooled condenser.For a refrigerator, it is important to keep the condenser clean, just as it is important to keep the water level up in the radiator of a car. At regular intervals, not exceeding two months, and more frequently in dusty areas, remove the grill that is placed in front of the condenser- the condenser being a metal finished assembly having a copper tube running through the fins, and similar in appearance to the car radiator. Dust usually forms a coating over the condenser, which may be removed by brushing or vacuum cleaner. Sometimes this dust collects within the fins and must be removed. The vacuum cleaner pulls this out provided the condenser has not become thoroughly clogged. If this occurs, it may be necessary to use a high-pressure gas to blow this dust out, in which case, a call should be lodged with our service department to have the condenser blown out. After cleaning, always check to see that the condenser is clean right through the fins, a torch usually being needed to ascertain this. Refit the grill in the front of the condenser when cleaning is completed. Some small low temperature cabinets do not have a finned condenser, but a plate, or wire type of condenser, similar to those used on household refrigerators, or alternatively; have the outer skin of the refrigerator as a condenser. This is usually evident by a slightly warmer outer cabinet temperature than that of the surrounding objects. Warning - breakdowns due to a blocked condenser are not covered by warranty. |
