2. Unpacking
After removing the packing material, check the appearance of
the ice maker for possible defects or irregularity.
If the product shows any irregularity in its appearance, contact
your local distributor.
All the packing material (straps, box, Styrofoam, and wood,
etc) should not be left within reach of children and should be
disposed of.
For safety, the product should be installed and used with
caution and in accordance with the User’s Manual.
Incorrect installation or careless use of the product may
damage or injure the environment, humans, animals, and/or
materials and property. The manufacturer does not bear any
responsibility for the aforesaid damage or injury.
This ice maker performs best at an ambient temperature of
50~75℉ and water temperature of 50℉.
The ice maker should be installed in a controlled indoor
environment, but it should NOT be installed near a heat source
such as a heater, stove, or dish washer.
Outside air
The ice maker takes in ambient air through the left portion of
the kick plate/grill and expels hot air through the right portion
of the same kick plate/grill. If any material is placed in front of
the kick plate/grill, the air flow will be restricted, resulting in
reduced performance and, in the worst case, malfunction. The
ice maker should be operated within an ambient temperature
range of 50℉ to 100℉.

Water supply
The ice maker requires a continuous supply of potable water at a
pressure of 20-80psi
Water quality
There is no such thing as “perfectly pure” water. All kinds of
water, including tap water, contains impurities. Rainwater absorbs
impurities from the atmosphere and/or when it passes through soil.
Some impurities consist of solid particles called suspended solids
and are filtered through micro filters. Any remaining impurities,
which cannot be filtered because they are chemically combined
with water molecules, are called dissolved solids.
The mineral content of the ice produced by this product is reduced
compared to the content in the water before conversion into ice.
Water containing a low level of impurities is rapidly frozen. The
reason for this is that the impurities elevate the temperature of
water. Through such an action, most of the impurities condensed
in the water-tank of the ice maker form what’s known as scale.
This icemaker reduces the mineral level by circulating water during
the harvest cycle (the excessive quantity is removed through an
outlet tube).
Each cycle requires about 0.64 quarter (0.6ℓ) of water. For each
quarter, about 0.5 quarter is used in rinsing the water tank and the
remainder is removed through the outlet pipe.
In this process, some impurities unavoidably remain and may
accumulate on the internal parts of the ice maker, forming
abnormal ice pieces. If a large quantity of mineral scale
accumulates, the lifespan of the ice maker may be reduced.
For best operation of the ice maker, impurities and minerals should
be removed by washing with ice machine cleaner periodically. The
method of cleaning the ice maker is described on page 18.
In general, it is best to use filtered water. Water filtration may
remove not only bad odor but also scale.
Water softener is not recommended because it exchanges
minerals. If the hardness of the water is very high, using a water
softener may lead to opaque pieces of ice.
If you have any questions about the purity of your water, contact a
water treatment expert in your area.
This product was thoroughly cleaned at the factory. However, it is
advised that you check the cleanliness of the machine before use
and maintain its cleanliness during use.

The cleaning process takes about 10 minutes and
performs the following operations.
①After water is supplied to the first water tank,
the AUGER operates for 5 minutes.
At this time, if you want to add the cleaning solution,
put it in the ice outlet.
②After the above process is complete, drain and re-water.
③After that, operate the AUGER for 1 minute.
④Repeat steps ②and ③twice more,
drain and stop the product.
Important Information: Do not put anything other than ice in the
ice bin. Wine or beer bottles are unsanitary and a
detached label may block the drainpipe.
Ice container
The product continues making ice until the level of ice reaches
the temperature sensing tube (right side). It then ceases
operation.
