Ice
The ice has a "top hat" shape (refer to Figure 10). Newly produced ice is clear and transparent,
The inside
of the ice is sometimes cracked; however, such cracks commonly occur in the production process and
disappear with time. Ice stored in the container for a long time may gather frost on the outside and look
cloudy. This is normal. Once water is poured on the ice, the frost will disappear.
Ice Container
The product continues making ice until the level of ice reaches the temperature sensing tube (right side). It
then ceases production.
The model with a drain pump drains away melted ice when the ice maker is turned
off. The pump works for only several seconds.
Operation
Time
It takes about 20-35 minutes to produce a set of 24 ice cubes. The length of one cycle of the ice maker (ice
production and ice removal) differs depending upon the cleanliness of the ice maker, the surrounding
temperature, and the temperature of the water supplied to the ice maker. It takes about 10-12 hours to fill
the empty ice container with ice.
Ice Production
The ice production process largely consists of two cycles - ice production and ice removal. 24 ice cubes are
produced with each cycle of ice production and ice removal.
When water is sprayed onto the surface of the
frozen ice-forming mold, the ice production cycle starts. When ice is removed and water is supplied to the
ice maker, the ice removal cycle begins again.
Ice Removal Cycle
The compressor works during the progression of the ice removal cycle, but the pump motor and fan motor
will stop. The hot gas valve and water supply valve turn on. When the two valves are opened and the frozen
surfaces are heated, ice drops down into the container. Then the ice removal cycle is stopped and the ice
production cycle starts again automatically.
How Ice is Produced
The ice maker draws water from the fixed water source that feeds into the water container. When water is
sprayed onto the surface of the ice-forming mold, the water not containing mineral impurities freezes and
attaches to the ice-forming mold. The water containing impurities drops down into the water container.
As
the ice production cycle progresses, the mineral impurity level in the water container rises. During the ice
removal cycle, water is fed into the ice maker, thus diluting the water in the container and washing a portion
of the concentrated minerals out through the drain pipe.
