INSTALLATION

UNPACKING
Once the machine has been received, it must be moved to the place where it will be installed:

1. Make sure that nobody is within the lifting and load movement operation radius and, in particularly difficult situations, use personnel who control the movements to be carried out.
2. Moving the machine must be done by at least two people in a vertical position.
3. Avoid bumpy routes, paying attention to the dimensions and possible protruding parts.
4. It is prohibited to make additional cuts in the packaging.
5. Try not to damage the packaging as it could be used again in the future.
6. In the established place and to connect to the network.

Damages that the machine may suffer during transport and moving are not covered by the warranty. Repair and replacement of parts that may get damaged must be paid for by the customer.

TREATMENT OF PACKAGING
Recycling: On the one hand, it can be subdivided according to the type of materials of which it is made up and they can be treated according to the provisions of the rules enforced in the country where the machine is located.
Conserve for future use: On the other hand, it is possible to conserve the packaging as it might be useful for future movements or transport of the machine.

BEFORE THE FIRST START-UP
Washing and Sanitation: It is recommendable to carry out careful cleaning and sanitisation of the machine.
Parameter Configuration: Perform the INSTALL procedure and configure the parameters required.

POSITIONING
All of the operations illustrated in this section are to be exclusively carried out by specialised technicians, those who have to organize the different operative sequences and the use of suitable means to act at all times within the rigorous application of current standards regarding this matter.
The following requirements must be met before installing the machine in the establishment:

1. That the network voltage coincides with the one indicated on the identification label.
2. Operating room temperature: 20°C and 40°C 68°F and 104°F.
3. Must be installed in a place where it can be monitored by qualified personnel.
4. It must be placed horizontally on a solid, flat and stable surface.
5. Easy access to the plug.
6. That the laws and current technical standards are complied with when carrying out the installation.

OPERATION

PRODUCTS SAFE TO USE

• Water + Liquid Concentrate
• Water + Powder Concentrate
• Alcohol
• Filtered Fruit-Based Product
  In any case, the amount of sugar must be between 11%-20%. A lower concentration may damage the spiral beaters and/or the motors.

FILLING THE BOWL
Assemble Air Filter: Locate the filter in the machine’s packaging, insert it into the groove, at the bottom of the chassis, at the front. Slide it completely until it stops. (Fig. 1)
Open the Lid: Lift the front part. (Fig. 2)
Filling the Bowl: Do not use liquids with temperatures over 25ºC/77ºF.
Filling Level: MAX up to sticker; MIN cover the evaporator. (Fig. 3)
Close the Lid: Lower the front part.
PREPARING COLD DRINKS
Start-Up: Push the Main switch. Machine charged. (Fig. 4)
Slush: Press OPERATING MODE Until the display shows: SLUSH (Fig. 5)
Cold Drink: Press OPERATING MODE Until the display shows: STANDBY (Fig. 6)

During Preparation We Can See:

SERVING THE PRODUCT
The Push and Pull tap allows us to serve the product in two different ways:
Pull: Pull the handle. (Fig. 7)
Push: Push the handle. (Fig. 8)

IF ICE CRYSTALS APPEAR
Select Defrost Mode: Press OPERATING MODE Until the display shows: DEFROST (Fig. 9)
Allows you to defrost the product quickly. Wait until Defrost finishes. (During Defrost, Slush and Stand By mode of any tank is deactivated)
Prepare Slush: Press OPERATING MODE Until the display shows: SLUSH (Fig. 10)
In this way, the slush always remains homogeneous and prevents the formation of excessively large ice crystals.

CLOSE PREMISES (STANDBY MODE)

Select Standby Mode: Press OPERATING MODE Until the display shows: STANDBY (Fig. 11)
During the periods when the establishment is closed, it is possible to use the machine in maintenance mode. In this way, you will save a considerable amount of electrical energy
as the compressor only operates during the strictly required time to maintain the right temperature for the product(max. 3ºC)
(max. 37.4 ºF).
