Requirements for plumbing
Plan the arrangement of the water supply pipes.
Connect a 1/4" diameter copper cable with the tap water pipe.
Install a shutoff valve between the tap water pipe and the product so that the user can operate the valve.
Do not install the shutoff valve at the back of the product. Do not use a self-piercing valve. If the tap water
has a high level of minerals, a pipeline filter will be required.
The pressure of the tap water should be maintained at a level between 20psi (1.4bar) and 80psi (5.5bar).
The tap water and drain pipeline should be planned and prepared at the place of installation. If an electric
outlet is available just at the back of the ice maker, installation may be easier. The electric power, tap water
pipeline and drain pipeline should satisfy all the provisions under local laws and regulations. For the position
of the tap water, refer to the installation specifications and drawings on
pages 10 and 11.
Important Information: The dispenser is designed for use in a fixed position but it may be necessary to pull
the unit forward for service. Therefore, do not install any material at the front, upper or lower end of the
product which may act as an obstacle when moving the ice maker.
Water quality
•
There is no such thing as “perfectly pure” water. All kinds of water including tap water contain some
impurities. Rainwater absorbs impurities from the atmosphere or when it passes through soil. Some
impurities consist of solid particles called suspended solids and are filtered through micro filters. Any
remaining impurities cannot be filtered because they are chemically combined with water molecules.
These impurities are called dissolved solids.
•
The mineral content of the ice produced by the dispenser 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 the water. Through such action, most
of the impurities condensed in the water-tank of the dispenser form a hard precipitation called scale.
•
This dispenser reduces the mineral level by circulating water during the harvest cycle (the excessive
quantity
is removed through the outlet tube). Each cycle requires about 0.64 quart (0.6ℓ) of water. For
each quart, about 0.5 quart is used in rinsing the water tank and the remaining quantity 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 abnormally-shaped ice cubes. If a large quantity of mineral
scale accumulates, the lifespan of the dispenser may be reduced.
•
For best operation of the ice maker, impurities and minerals should be decomposed by washing
periodically. The method of cleaning the dispenser is described on pages 18 -19.
•
In general, it is best to use filtered water. Filters may remove not only bad odor but also particles.
Neutral water is not recommended.
•
Water softener is not recommended because it exchanges minerals. If the hardness of the water is
very high, softening may lead to the formation of opaque pieces of ice.
•
If you have any questions about the purity of your water, address your inquiry about water treatment
to an expert in water quality.
•
This product was thoroughly washed at the factory. However, check the cleanness of the inside before
use and keep it clean during use.
