technician for repair.
lOtherwise, fire or
product breakdown may occur.
Be sure to use only water and neutral detergent when washing
the product and thoroughly remove moisture on the product.
lOtherwise, fire or electric shock may occur.
Product breakdown may also occur.
Never use gasoline, thinner,
or chlorine-based bleach.
When not using the product, thoroughly clean the

rod, drum plate, etc. and keep them in a safe place.
lDo not use rough steel wool, etc.
(Product surface damage may occur.)
Do not put the product in a place where freezing burst is likely
to occur.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
(Product surface damage may occur.)
lIce-making materials may go rotten, and malodor
may be generated.
lFreezing burst is likely to occur if the water inside the cooling
water coil and pressure valve freezes.
lIn unavoidable situations, completely drain the water inside the
cooling water coil first.
Never use a tool with sharp edge or tip such as ice pick or
knife in order to remove the ice on the drum surface.
If the surface is damaged, refrigerant may leak, or ice quality
may be deteriorate.
Caution (when installing)
Install and use the product at a place where the
ambient temperature is between 10℃and 43℃.
Cooling water temperature must be between 5℃
and 25℃.
lIf the product is operated outside of the temperature
range specified above, product breakdown may occur.
lIf the product is operated outside of the temperature
range specified above, the ice quality and ice-making
quantity may be changed.
lThe ice-making quantity may differ depending on the
temperature and humidity.
lIf ice making is not capable due to high-temperature
drained cooling water, use a cooler to lower the
cooling water temperature.
To maintain normal ice making, use a separate cooler.
When using the product, the cooling water pressure should be
between 1 bar and 6 bar.
lIf the pressure of the cooling water exceeds 6bar,
install a pressure reducer.
lIf the pressure is below the recommended pressure
range, use a booster pump.
Ask the service center for a booster pump (option).
The product, when installed, must be level.
lThe deviation between front, rear, left, and right
should be 2mm or less when using the product.
(Otherwise, the quality of snow-pattern ice may
not be uniform, or the ice-making itself may
not be possible.)
6bar or
less
10℃~43℃

3Management 3-1. How to wash and clean on a daily basis
Washing the ice maker (daily)
After the ice-making operation, wash the drum surface, material container, drum plate, etc. on a daily basis.
(Failure to do so may cause bacterial growth and bad smell due to the spoilage of the ice-making material.)
uBefore performing the cleaning operation, be sure to unplug the power plug from the electrical outlet.
uWhen washing the ice-maker, do not sprinkle water directly onto the product (except for the drum surface).
uWhen washing the ice-maker, use clean hands and cloth only.
uNever use abrasive powder, powder detergent, oil, hot water (40℃or above), rough wire brush, acids, thinner, benzene,
alkaline detergent, etc. Otherwise, the plastic surface may be damaged.
uBefore using cleaning agent or fungistatic agent, refer to the precaution on the container label of such products.
uResidual cleaning agent or fungistatic agent may cause adverse effect on health or rusty surface. Completely remove
any residuals of such products.
uNever clean the inside of the machine unless an authorized service technician is required to do so. It is very dangerous
to clean the inside of the machine.
uNever use a rough wire brush, etc. (may cause scratches on the surface of the ice-making plate, material container,
etc., resulting in bad smell, bacterial growth, etc. when the material gets caught within the scratches and goes bad).
uContainer designed to receive ice
uCleaning liquid: Dilute any commercially available neutral detergent with water at a ratio of 1:500 (add 1ℓ of water to
about 2.0㎖of cleaning liquid)
uFungistatic agent: Rubbing alcohol in spray container (concentration of 50~80%)
