② The slush forming time is affected by various factors such as
ambient temperature, initial material temperature, sugar level
(Brix level) and viscosity setting. Though the conditions are
the same, the forming time may vary depending
on the canister.
(The sensor on the front of the drum detects temperature.)
③ To reduce the beer forming time and increase the productivity,
it is recommended to use the refrigerated materials.
④ To reduce the granita forming time and increase the productivity, when the remaining
material level drops below half, fill the material in the canister.
⑤ To preserve the material safely, be sure to operate the product in soft drink mode.
To leave the material in the canister during all night without refrigeration, operate
the product for at least one hour while the freezing/refrigeration switch is in“II”
before switching off the product.
⑥ The product has the shaft so that the gear motor (outside the canister) can drive
the spiral (inside the canister).
⑦ The product must be located in a well vented place.
If the temperature of the product is hot, check whether there is any heat generating
source, or air flow through the panel with a hole is blocked by teh wall or box.
Keep at least 30 cm distance between the product and other materials.

As shown in the figure, on a monthly basis,
open the cover of the condenser,
clean the filter with lukewarm water (about 25℃) or
neutral detergent solution, dry it, and attach it back
to its original position. If ventilation is not made due
to accumulated dust, slush is not smoothly formed
and machine failure may follow. When the troubles
are caused by careless use or user faults such as
no filter cleaning, you can get a charged service.
When cleaning the product, be careful not to insert water in the electrically running parts.
It may cause an electric shock or product failure.
① Prepare the solution mixed with five liters of warm water and kitchen detergent.
Do not use a strong detergent.
② Mix an appropriate amount of food grade detergent with water,
pour it into the ingredient tank, operate the product in "WASH" mode for about 2 minutes,
and then drain the mixture.
③ Frequently empty the remaining materials in the material box and drain box
and clean them.
