7. Use

[Warning] AFTER INSTALLATION, WAIT AT LEAST TWO HOURS BEFORE TURNING ON THE APPLIANCE.

7.1. Intended Uses

The chiller is an appliance with a powerful refrigeration system capable of rapidly lowering the temperature at the core of food products. It is ideal for use in kitchens, pastry shops, and ice cream parlors. The main work cycles the machine can perform are chilling (CHILLING) and freezing (FREEZING). Each cycle offers two distinct end-of-execution modes corresponding to the start of preservation: by temperature (when the probe inserted into the product's core causes the cycle to end upon reaching the set temperature) or by time (when the cycle ends after the set time has elapsed).

• SOFT CHILLING: Positive (+3°C) "delicate" chilling. Freshly baked products are placed in the chiller for a brief period, not exceeding 90 minutes, to reach 3°C, thereby inhibiting bacterial proliferation and preventing dehydration of the cooked product. Products treated this way can be perfectly preserved for 5-7 days without altering their original qualities.
• HARD CHILLING: Positive (+3°C) "rapid" chilling. It always has a maximum duration of 90 minutes. This type of process is used when the product to be cooled has a thickness greater than 2-3 centimeters (i.e., large pieces) and for dense or fatty foods. The appliance adjusts air temperatures to accelerate cold penetration into the product.
• FREEZING: Freezing (-18°C). This work cycle allows the core of the product to reach -18°C in less than four hours (240 minutes). The speed of the process prevents the formation of macro-crystals, ensuring that upon final use, the frozen food retains its original consistency, color, and quality.
• CONSERVATION: At the end of each cycle, whether chilling or freezing, the machine will automatically switch to the preset conservation temperature.

7.2. Unintended Uses

The chiller is not intended for uses other than those described in section 7.1. In particular, the chiller is not suitable equipment for indefinite food storage.

7.3. Residual Risks

[Warning] DANGER OF FROSTBITE DUE TO FREEZING.

During its work phases, the appliance can manage very low temperatures: avoid direct contact with internal parts of the machine after opening the door.

7.4. Control Panel

Figure 7: Mychill Chiller Control Panel. This image shows the layout of the control panel with buttons labeled START/STOP, AUX, and icons for temperature adjustment and cycle selection.

Control Buttons:

• PLUS AND MINUS BUTTONS: Allow increasing or decreasing the value displayed.
• DEFROST BUTTON: When the machine is in STANDBY and/or during conservation, pressing this button initiates manual defrosting.
• CHILLING BUTTON: When the machine is in STANDBY, a simple press selects a chilling cycle. Pressing and holding for 3 seconds activates the continuous cycle.
• HARD / SOFT BUTTON: With a cycle selected, each press allows selection between HARD or SOFT mode.
• FREEZING BUTTON: When the machine is in STANDBY, a simple press selects a freezing cycle.
• AUXILIARY BUTTON: Pressing this button activates accessory functions, such as the UV lamp or heated probe, if installed.

Icons on the Control Panel Display:

• OFF: Lit when the machine is in OFF state and off otherwise.
• CELSIUS (°C): Can be lit in red or green and indicates the temperature unit.
• CHILLING AND FREEZING: Flashes while the corresponding cycle is in progress and remains lit during the subsequent conservation cycle.
• TEMPERATURE: Lit during the temperature-controlled cycle.
• TIME: Lit during the time-controlled cycle.
• CONSERVATION: Lit steadily or intermittently during the conservation phase.
• CONTINUOUS CYCLE: Lit steadily or intermittently during the pre-cooling phase, also known as CONTINUOUS CYCLE.

7.5. Control Procedures

The appliance is globally controlled by an electronic card. When the machine is powered on, the display performs a brief "lamp-test." If a cycle was in progress before power loss, it will resume where it left off. With the card OFF, the display is completely dark except for the [Power] icon. Pressing START/STOP turns off the [Power] icon and enters STANDBY mode, showing the cabinet temperature in blue. Using the panel controls and display indications, various machine functions can be activated. In STANDBY, you can switch between cycles by pressing the CHILLING and FREEZING buttons. With a cycle selected in STANDBY, press START/STOP to initiate it. Pressing STOP halts an ongoing cycle. Acoustic signals can be silenced by pressing any button. Pressing START/STOP for 3 seconds turns the card OFF.

7.6. Usage Procedures

Before using the machine, clean the interior of the cabinet. If the appliance has been idle for a long period, run it empty until the set temperature is reached. For optimal performance, arrange products to allow air circulation: do not obstruct the fan intake, do not overlap trays, distribute loads evenly, and avoid covering containers with lids or insulating films. To prevent food spoilage, do not overload the machine beyond permitted quantities, use thicknesses not exceeding 50-70 mm, and avoid unnecessary door openings. Clean and sterilize the probe before each use. Place the probe in the thickest part of the food, ensuring the tip does not protrude or touch the tray. To improve cycle efficiency, pre-cool the cabinet by turning the machine on at least 15 minutes before introducing products, for both chilling and freezing.

7.7. Soft Chilling

7.7.1. Selecting and Setting a Soft Chilling Cycle (Delicate Positive Chilling)

Load the food items appropriately and insert the probe into the product if a temperature-controlled cycle is desired. Close the door. In STANDBY, press the [Chilling Icon] button: the display shows the set cell temperature (default -5°C) with the [Chilling Icon] and [Time Icon] flashing. Use the Up/Down arrow buttons to adjust this value. Press START/STOP (START) to begin the cycle: the display shows the cabinet temperature, and the [Chilling Icon] and [Time Icon] remain lit. As previously described, the device performs automatic probe recognition (approx. 2 min). The cycle will then confirm as probe-controlled or switch to time-based. If the probe test is positive, the cycle proceeds by temperature (probe), and the probe temperature is displayed. If the probe test is negative (after acoustic signal and flashing icon), the display shows the [Time Icon], and the cycle proceeds by time. Use the Up/Down arrow buttons to adjust this value. While the remaining time is displayed, pressing the [Chilling Icon] and [Freezing Icon] buttons allows viewing the cabinet temperature. You can directly select a time-based cycle without the automatic probe recognition phase. In STANDBY, press the [Chilling Icon] button twice: the display shows the cycle duration (90 min) with the [Chilling Icon] and [Time Icon] flashing. Use the Up/Down arrow buttons to adjust this value. Then, press START/STOP to start the cycle. Once the 90-minute cycle time elapses or the core temperature reaches +3°C, the display automatically switches to conservation mode (+2°C cabinet temperature), signaled by an acoustic buzzer. The display will show the [Conservation Icon]. At any time, you can interrupt a cycle by pressing START/STOP (STOP); pressing START/STOP (START) again will restart the cycle.

7.8. Hard Chilling

7.8.1. Selecting and Setting a Hard Chilling Cycle (Rapid Positive Chilling)

Load the food items appropriately and insert the probe into the product if a temperature-controlled cycle is desired. Close the door. In STANDBY, press the [Chilling Icon] button: the display shows the set cell temperature (default -5°C) with the [Chilling Icon] and [Time Icon] flashing. Use the Up/Down arrow buttons to adjust this value. Pressing the [Hard Chilling Icon] activates the hard phase; the HARD symbol will flash on the display. Press START/STOP (START) to begin the cycle: the display shows the cabinet temperature, and the [Chilling Icon] and [Hard Chilling Icon] remain lit. As previously described, the device performs automatic probe recognition (approx. 2 min). The cycle will then confirm as probe-controlled or switch to time-based. If the probe test is positive, the cycle proceeds by temperature (probe), and the probe temperature is displayed. If the probe test is negative (after acoustic signal and flashing icon), the display shows the [Time Icon], and the cycle proceeds by time. Use the Up/Down arrow buttons to adjust this value. While the remaining time is displayed, pressing the [Chilling Icon] and [Freezing Icon] buttons allows viewing the cabinet temperature. You can directly select a time-based cycle without the automatic probe recognition phase. In STANDBY, press the [Chilling Icon] button twice: the display shows the cycle duration (90 min) with the [Chilling Icon] and [Time Icon] flashing. Use the Up/Down arrow buttons to adjust this value. Then, press START/STOP to start the cycle. Once the 90-minute cycle time elapses or the core temperature reaches +3°C, the display automatically switches to conservation mode (+2°C cabinet temperature), signaled by an acoustic buzzer. The display will show the [Hard Chilling Icon]. At any time, you can interrupt a cycle by pressing START/STOP (STOP); pressing START/STOP (START) again will restart the cycle.

7.9. Freezing

7.9.1. Selecting and Setting a Freezing Cycle (Congelation)

Load the food items appropriately and insert the probe into the product if a temperature-controlled cycle is desired. Close the door. In STANDBY, press the [Freezing Icon] button: the display shows the set cell temperature (default -40°C) with the [Freezing Icon] and [Time Icon] flashing. Use the Up/Down arrow buttons to adjust this value. Press START/STOP (START) to begin the cycle: the display shows the cabinet temperature, and the [Freezing Icon] and [Time Icon] remain lit. As previously described, the device performs automatic probe recognition (approx. 2 min). The cycle will then confirm as probe-controlled or switch to time-based. If the probe test is positive, the cycle proceeds by temperature (probe), and the probe temperature is displayed. If the probe test is negative (after acoustic signal and flashing icon), the display shows the [Time Icon], and the cycle proceeds by time. Use the Up/Down arrow buttons to adjust this value. While the remaining time is displayed, pressing the [Chilling Icon] and [Freezing Icon] buttons allows viewing the cabinet temperature. You can directly select a time-based cycle without the automatic probe recognition phase. In STANDBY, press the [Freezing Icon] button twice: the display shows the cycle duration (240 min) with the [Freezing Icon] and [Time Icon] flashing. Use the Up/Down arrow buttons to adjust this value. Then, press START/STOP to start the cycle. Once the 240-minute cycle time elapses or the core temperature reaches -18°C, the display automatically switches to conservation mode (-25°C cabinet temperature), signaled by an acoustic buzzer. The display will show the [Freezing Icon]. At any time, you can interrupt a cycle by pressing START/STOP (STOP); pressing START/STOP (START) again will restart the cycle.

7.10. Special Uses

7.10.1. Pre-cooling Function or Continuous Cycle

If the temperature of the goods to be chilled is very high (above 65°C), it is advisable to pre-cool them as follows:

Press and hold the [Continuous Cycle Icon] button for a few seconds; the machine will start, and the LED will flash intermittently. Upon reaching the set point (-30°C), the LED will remain fixed, and you can then select any cycle or load the machine with food items to be chilled. The new cycle formulated will "overwrite" the continuous cycle without needing to turn off the machine beforehand. This continuous cycle is ideal for ice cream parlors where work cycles are frequent (HARDENING) and only requires the cabinet temperature parameter, not time.

7.10.2. Defrosting

Evaporator defrosting occurs when the compressor stops. It can be Automatic or Manual and is indicated on the display by the disappearance of the message "dEF", first steady, then flashing during dripping. Automatic defrosting occurs only during the conservation phase every 6 hours, lasting a maximum of 15 minutes at an evaporator temperature of 8°C. Manual defrost can be activated when the card is in STANDBY and the evaporator temperature does not exceed +8°C by pressing the [Defrost Icon]. Since the compressor is already off in STANDBY, manual defrost forces ventilation; therefore, it is advisable to keep the door open throughout the phase.

7.10.3. Long Period Stops

Turn the machine OFF by pressing the START/STOP button for 3 seconds and disconnect the plug. Thoroughly clean the machine (as per section 8.2) and ensure the door is left open upon completion of the operation and throughout the period of inactivity.

Procedure: For correct and efficient appliance operation, the air condenser (ref. 1 fig. 9) must be kept clean to allow free air circulation. This operation should be performed at least every 30 days. Remove the control panel by unscrewing the screws (ref. 2 and 3 fig. 9). Clean with non-metallic brushes to remove all dust and lint from the fins. It is recommended to use a vacuum cleaner to prevent dust dispersion. If greasy residues are present, remove them using a brush moistened with alcohol.

[Warning] DO NOT SCRAPE SURFACES WITH SHARP OR ABRASIVE OBJECTS.

Figure 9: Air Condenser and Control Panel. This diagram shows the condenser unit and the control panel of the chiller.

[Warning] The condenser has sharp edges. During the operations mentioned above, always wear protective gloves, goggles, and respiratory protection masks.

[Warning] Do not clean the equipment using water jets.

8.2.5. Cleaning the Probe

This operation should be performed after each cycle. Appliance State: Power button in OFF position. Authorized Personnel: Operator responsible for appliance use.

Procedure: Before each new cycle and to prevent any product "contamination", it is necessary to clean the probe (ref. 1 fig. 10). Remove any residue using a sponge dampened with neutral detergent. Rinse thoroughly and treat with a sterilizing product.

Figure 10: Chiller Probe. This diagram shows the probe used for temperature measurement.

[Warning] Avoid pulling the probe cable, as it could be damaged.

[Warning] The probe has a particularly sharp terminal. During cleaning operations, always wear protective gloves and exercise maximum caution.

8.3. Extraordinary Maintenance

If the appliance requires extraordinary maintenance or exhibits operational anomalies not covered in this manual, please contact the manufacturer.

8.4. Operational Anomalies and Faults

It is important to note that, regardless of the machine's state, pressing the START/STOP button for 3 seconds turns the card OFF. Any operational anomaly is accompanied by an intermittent buzzer sound and indicated by a red code on the display. The acoustic signal can be silenced by pressing any button.

8.4.1. Alarms

The possible alarm signals on the display are as follows:

• "tiME": Alarm for chilling or freezing cycles not completed within the maximum duration (HACCP alarm). The alarm has no effect; it is simply memorized.
• "AL": Minimum temperature alarm. The alarm has no effect during any cycle.
• "AH": Maximum temperature alarm. The alarm has no effect during any cycle.
• "HP": High-pressure switch alarm. No effect in STANDBY. During any work phase, it causes cycle blockage and switching to STANDBY. The cause of the alarm must be eliminated, then the machine turned off (3-second START/STOP press) and restarted (START/STOP [START]). This alarm can be triggered by high ambient temperature (above the admitted limit, see section 2.4) or by a dirty condenser (which must be remedied immediately as indicated in section 8.2.4).
• "id": Door open alarm. The signal has no effect and ends when the door is closed.

8.4.2. Errors

The errors recognized by the electronic controller are:

• "Pr 1": Cell probe error. Prevents cycle initiation in STANDBY. In chilling or freezing, it causes cycle stoppage and switching to STANDBY. During conservation, however, the cycle is not interrupted, and the compressor cycles to maintain cabinet temperature. The probe connection must be checked and, if necessary, replaced.
• "Pr 2": Probe error. Prevents temperature-based cycle initiation in STANDBY. In chilling or freezing, it switches to a time-based cycle. During conservation, it has no effect. The probe connection must be checked and, if necessary, replaced.
• "Pr 3": Evaporator probe error. No effect in STANDBY, chilling, freezing, or conservation. A defrost cycle may terminate by time-out.

9. Dismantling

[Warning] For any dismantling activity, contact the manufacturer.

10. Disposal

10.1. Disposal Method

Equipment State:

• Electronic card in OFF position ('O').
• Power plug disconnected from the mains.

Modalities:

The equipment is manufactured with ferrous materials, electronic components, and plastics. If dismantling is necessary, separate the components by material type to simplify differentiated disposal or potential reuse of parts. The equipment must be disposed of separately from urban waste. When dismantling the equipment, no special instructions are required. Entrust dismantling to authorized disposal companies or, where legally provided, deliver it to the vendor (see also "Information for Users on Waste Disposal within the European Union" below). Always observe the laws in force in the country of use for dismantling (see also "Information for Users on Waste Disposal within the European Union" below).

[Warning] PAY ATTENTION: THE EQUIPMENT CONTAINS REFRIGERANT GAS WHOSE CONTROL AND RECOVERY MUST BE HANDLED ACCORDING TO CURRENT REGULATIONS IN THE COUNTRY OF DISPOSAL.

[Warning] For any dismantling activity of the appliance, contact the installer.

Information for Users on Waste Disposal within the European Union

The symbol of a crossed-out wheeled bin appearing on the appliance or its packaging indicates that the product, once it has reached the end of its life, must be disposed of separately from other waste.

Users must deliver the equipment at the end of its life to appropriate collection centers for differentiated disposal of electrical and electronic waste, or return it to the vendor when purchasing an equivalent new equipment on a one-to-one basis. Proper differentiated collection for subsequent recycling, environmentally compatible treatment, and disposal contributes to avoiding potential negative effects on the environment and health, and promotes the reuse and/or recycling of the materials composing the equipment. Improper disposal by the user will result in the application of penalties provided by the laws in force in the country of disposal.
