6. After easy cleaning, press the stop key to back to the main screen and enter Standby.

Preparing the ice cream mix

1. Use ice cream mix intended for use in ice cream machines only, either it is powder or concentrate.

2. Mix the powder or Dilute the concentrate with drinking water in a container, always following the manufacturer’s instructions. Or cause damage to the beaters and gear motors may happen. Damage caused by using incorrect mixture will invalidate the warranty.
   For example, when ice cream powder is used,the recommended ratio is 1kg ice cream powder to 2.5-3 litres drinking water.

3. Let the mix settle down for about 5 minutes.

Filling the ice cream mix

Note:

• Before filling, ensure to add water into both hoppers to test the sealing to prevent leakage.

• Before filling, ensure there is no moisture residual inside the cylinder.

  1. Pull down the handle to raise the valve poles,then fill in small amount of ice cream mix.

  2. Water will flow out via the discharge outlets.
     When seeing the mix is out, raise the handle.

  3. Fill the prepared mix into both hoppers, at least covering the hopper bottom.

Warning:

• Do not fill the hoppers with hot liquid.
• This appliance has 2 cylinders to be cooled simultaneously thus always ensure both hoppers are filled with ingredients. Otherwise, the cylinder will freeze and may cause the beater to wear.

Inserting the expanded tube assembly

1. Use food safe lubricant to fit all the seals into place. Place the inner tube into the outer tube

2. Selecting the feeding hole: To ensure a stable feeding, the volume into the cylinder can be set by selecting a desired feeding hole.
   There are 3 holes:

   • Big hole: Big volume
   • Medium hole: Medium volume (default setting)
   • Small hole: Small volume
     Pull up the inner tube and rotate horizontally to select. The selected hole size can also be identified by the arrowed hole size mark on the top.

3. Insert the expanded tube into the hopper hole.

   • Warning: After switched on, DO NOT put fingers into the feedstock inlet to avoid possible injury.

   • Note: When not in use for more than 1.5 hours, ensure to rotate the inner tube to close the expanded tube (as shown below).
     Note:

   • When the ice cream mix is very thick and condensed, it will flow very slowly thus we do not recommend the use of the expanded tube assembly.
