Before First Use

IMPORTANT: Review all warnings at the beginning of this Owner's Guide before proceeding.

1. Press the on/off switch at the back of the unit. Switch is on when the side with the line is pressed down. The unit will now be operable.
2. Remove all packaging materials from the unit.
3. Wash all parts in warm, soapy water.
4. Thoroughly rinse and air dry all parts.
5. Wipe control panel, motor base, and evaporator with a soft cloth. Allow to dry completely before using.
6. Place the unit on countertop for at least 2 hours before operating. This allows the refrigerant to settle in the condenser for optimal and safe use.

NOTE: All attachments are BPA free. Accessories are dishwasher safe but should NOT be cleaned with a heated dry cycle.

Using the Control Panel

POWER: Press to power the unit on and off.

RINSE CYCLE: This cycle agitates, without cooling, to rinse the unit.

PRESETS: 5 unique presets use RapidChill Technology to determine the perfect temperature for the ideal frozen drink.

TEMPERATURE CONTROL SETTING: Each preset will start at a default/optimal temperature for ideal texture. If desired, adjust the temperature for your perfect frozen drink texture.

• For sippable frozen drinks, decrease the temperature level by pressing the bottom arrow (⬇️) on the control panel.
• For thicker, colder frozen drinks, increase the temperature level by pressing the top arrow (⬆️) on the control panel.

Troubleshooting Tips

• RECIPE NOT SLUSHING? If your recipe has not reached desired texture after 60 minutes, increase the temperature by one level. Wait 10-15 minutes to test recipe texture. If still not desired, increase by one level again. Repeat until desired texture is achieved.
• SLUSH NOT DISPENSING? For the best dispensing experience, fill the unit to the max fill line and ensure the unit is running. For a smoother dispense experience, decrease the temperature level by pressing the bottom arrow (⬇️) on the control panel. More sippable frozen drinks will dispense smoother.

Presets

Each preset will start at a default/optimal temperature for ideal texture. If desired, adjust the temperature for your perfect frozen drink texture.

Required Sugar Content

Too little sugar or too much alcohol will prevent proper freezing of a slush output. Follow guidelines below for a perfect slush every time.

All inputs must contain at least 5% sugar.

NOTE: Pre-frozen ingredients taste sweeter. Worried your drink might be too sweet? Don't worry, it won't taste as sweet after you freeze and slush it into a frozen drink.

Sugar Guidelines

Refer to drink/liquid nutrition label to ensure sugar content meets the recommended minimums below:

Diet and Low Sugar Drinks

Diet and low sugar drinks won't turn into slush when they're the only ingredient as too little sugar will prevent recipes from freezing properly. To turn your favourite diet and low sugar drinks into a Slushi, add the below ingredients to your input:

What is Erythritol?

Erythritol is a low calorie sweetener that offers a taste similar to sugar without significantly affecting blood sugar levels or contributing to tooth decay. It is widely used as a sugar substitute in various food products and is generally considered safe for consumption. As with all dietary components, it is advisable to consume erythritol in moderation as part of a balanced diet.

Troubleshooting Tips

• LOW SUGAR ALERT: If the sugar content of the input is too low, the unit will detect it and provide an alert. Temperature Control LEDs will flash one at a time in descending order starting with the top LED, and the unit will beep every minute for 15 minutes.
• IF A DRINK DOES NOT MEET MINIMUM REQUIREMENTS OF TOTAL SUGAR: Add 1-2 tablespoons flavoured syrup, sugar, date sugar, coconut sugar, maple syrup, agave, simple syrup, or honey per serving. Combine additional sugar with the base prior to pouring into unit. Reset the unit by pressing the preset. Restart by pressing the preset again.

NOTE: Artificial sweeteners will not aid in meeting total minimum or maximum sugar requirements.

Alcohol Guidelines

The perfect balance for your favourite frozen cocktails at home. When using the FROZEN COCKTAIL preset, all premade inputs (wine, beer, etc.) must be between 2.8% and 16% alcohol.

Hard Alcohol/Spirit Guidelines

To create frozen cocktails, see chart below for the maximum hard alcohol/spirit (vodka, tequila, etc.) content per total recipe size.

Chart above is a guide for incorporating hard alcohol/spirits (35% +) ONLY. When using other alcohols such as wine, beer, seltzer, or premade cocktails, refer to the Inspiration Guide.

Tips

• When using LIGHT or LOWER SUGAR drink mixes, omit water from the recipe and replace with additional light drink mix in the equal amount.
• When using premade mixes containing alcohol, omit addition of alcohol from chart instructions and replace with additional drink mix in equal amount.
• When using full sugar premade mixes with blender instructions, use ½ the amount of ice recommended on package instructions in the form of water.
• When using light sugar premade mixes with blender instructions, use ¼ the amount of ice recommended on package instructions in the form of water.

Tips & Tricks

• Keep unit upright for at least 2 hours before first use.
• DO NOT add hot ingredients.
• DO NOT add ice or solid ingredients like fruit, ice cream, or frozen fruit.

• All inputs must include at least 5% sugar.
• When using the Frozen Cocktail preset, all premade inputs must contain between 2.8% and 16% alcohol.
• For best results, chill liquid(s) or blended ingredients before adding to the unit.
• For the frostiest results, chill serving glasses before dispensing your frozen drink.
• For your ideal frozen drink texture, use the temperature control setting to adjust.

• For the best dispensing experience, fill the unit to the max fill line (1890 ml).
• You can run the unit up to 12 hours.
