Safe Chill™ Blast Chillers Service & Installation Manual

MAINTENANCE

The interior and exterior can be cleaned using soap and warm water. If this isn’t sufficient, try ammonia and water or a nonabrasive liquid cleaner. When cleaning the exterior, always rub with the “grain” of the metal to avoid marring the finish. Do not use an abrasive cleaner because it will scratch the metal.

In order to maintain proper refrigeration performance, the con- denser fins must be cleaned of dust, dirt and grease regularly. The condenser coil is located behind the removable louvered front and there are two coils located on the DBC-10. It is recommended that these be cleaned at least once every three months. If conditions are such that the condenser is totally blocked in three months, the frequency of cleaning should be increased. Clean the condenser with a vacuum cleaner or stiff brush. If it’s extremely dirty, a commercially available condenser cleaner may be required.

Door gaskets are dart style and can easily be replaced without the use of any tools. Do not use sharp tools or knives to scrape the bellows as this may tear the gasket and eliminate its ability to seal. Door gaskets should be cleaned as required to maintain their ability to seal properly. A soft bristle brush and solution of soap and water will keep the gaskets clean. Do not use full strength de-greasing agents on the gasket.

Pan slides are removable via the four thumb screws and are made of stainless steel. They are dishwasher safe or can be cleaned with soap and water.

Food Probes:

If necessary to check the probes, they are a 10,000 ohm thermistor and it is important that they be kept away from any high voltage wiring. There are four probes per section; two food probes, one box probe and an evaporator probe. Accessing the evaporator, expansion valve, and other evapora- tor components can be done by removing the pan slides and pulling the evaporator housing away slowly as to not pull out any wiring. Once access has been gained wire ties can be cut and the housing can be removed. Food probes can be cleaned with soap and water. For optimum use of the food probes, do not allow the handle to rest in the food. When removing a food probe from the food do not pull on the cable, use the handle.

The control uses a lithium battery and may need to be replaced approximately every five years.
