Ice Frost Operator’s Manual IMPORTANT WARNINGS AND ADVICE This instruction manual represents an integral part of the equipment and must be kept readily available for use. Read the warnings contained herein carefully before installing and using this equipment.
Ice Frost Operator’s Manual INSTALLATION 1. 2. Release the equipment from the packing, then slide it off upwards (see Figure 1). Checking the machine identification after removing the packing, you must check that the equipment you have received is exactly as you ordered, making sure the specifications indicated on the invoice or the delivery note are identical to those on the data plate. FIGURE 1 3.

Ice Frost Operator’s Manual BOWL LOADING OPERATIONS Alarms NOTE: See Acronym Definitions on page 17. Safety Probe Alarms (only for ICE FROST GENERIC Pre-mix) You will remember that the monitoring of the safety probes’ conditions (covered/uncovered) is only active during the bowl loading phase. It follows, then, that a lack of liquid in the tanks during the nonloading phases will not be signalled.
Ice Frost Operator’s Manual “FILTER CLEANING” Alarm A filter cleaning alarm will activate when the unit is running hot due to insufficient internal air circulation. When this occurs a “Filtr” message will appear on the touch pad LED display readout and an intermittent audible tone will also sound to alert the operator of this condition. The “Filtr” message will appear when the alarm activates (a beeping sound every 4-5 seconds).
Ice Frost Operator’s Manual ICE FROST GENERIC (POST-MIX) • Switch the machine’s main switch to the ON position (1). • Make sure the switch (L1) is in the OFF position (0) - Figure 6 - (switch L1 controls the flow of the products in the bowls). • Turn mixing motors OFF immediately. Do not run units with bowls empty. • Using an 8 mm socket wrench (E1), loosen the nut that holds the post-mix valve (D1).
Ice Frost Operator’s Manual PROGRAMMING ELECTRONIC TOUCH PAD To lower the control cover, use a coin or other object to turn the keyless lock to the horizontal position, in order to access the operating panel (controls are located on the right side of the unit). Auger ON/OFF Button Main Power Switch • Turns unit ON. o o • Selects 12/24 time or F /C temperature display when turned ON while simultaneously depressing the auger button.
Ice Frost Operator’s Manual Setting COLD Timer (Night Setting) 1. 2. 3. Turn the power switch ON. Make sure the “AUTO TIMER” is OFF (light on button is not lit). Press the left hand “Auger ON/OFF” button ON. Press and hold the “PRESS TO SELECT FUNCTION” button until you hear a long beep and the LED, “Cold” and the “AUTO TIMER” clock light begins to blink. 4. Press the “AUTO TIMER” clock button to set the unit to COLD mode and then press the “PRESS TO SELECT FUNCTION” button to save the setting. 5.
Ice Frost Operator’s Manual Viewing the Bowl Temperature 1. 2. Turn ON the auger on the side that you want to display the bowl temperature (press the “AGER ON/ OFF” button). Press the “PRESS TO SELECT FUNCTION” button until the “Cold” LED is lit. The display will now show the current bowl temperature in either oF or oC depending on which was selected. CONSISTENCY ADJUSTMENT 1. To dispense the product, place the cup beneath the tap (Q) and lower the lever (R) very gently (Figure10). 2.
Ice Frost Operator’s Manual QUARTERLY CLEANING AND SANITATION OPERATIONS ATTENTION: The cleaning operations must be performed with the machine disconnected from the power supply. 1. 2. 3. Empty the bowl of any remaining product and switch off the main switch “M”. Remove the cover (B) - Figure 27. With the post-mix version, see Figure 6 and 7 for details. Extract the quick couplings (C2) / (F2) - (Figure 12, 13, and 14). Pre-mix version Post-mix version FIGURE 12 FIGURE 13 FIGURE 14 4. 5.
Ice Frost Operator’s Manual 6. Slide the locking bar (Z) - Figure 16 - outwards so that the bowls are fully released. Unlock relief valve on the bowl lid cap and remove (Figure 17). 7. Unscrew the knobs (A1) so the bowls can be lowered slightly, open the tap to remove any remaining liquids and then extract it from its seating, pulling it outwards (Figure 17). FIGURE 16 Bowl Lid Cap FIGURE 17 8.
Ice Frost Operator’s Manual 11. Wash the bowl and cover carefully with water and mild detergent, rinse them well, and replace them, making sure the sealing strip (E1) is positioned correctly between the cover and the bowl. To guarantee the seal, the rounded part of the said sealing strip (as shown in Figure 21) must be facing the cover. FIGURE 21 12.
Ice Frost Operator’s Manual 17. Replace the tap, remembering to smear both is seating in the bowl and the seals (J) with Vaseline (Figure 25). FIGURE 25 18. Remove the drip tray (L1) by rotating it slightly and pulling it outwards (Figure 26). Wash all the parts carefully and reassemble it by following the prior operations, remembering to re-insert the condensation discharge pipe (M1) in its seating.

Ice Frost Operator’s Manual SPECIAL MAINTENANCE ATTENTION: To guarantee the cooling system a good performance level, the routine cleaning of the condenser filter is essential. As explained earlier, an audible signal accompanied by the word FILT appearing on the control panel display, will warn the operator when the filter is clogged and so must be cleaned before the machine comes to an automatic stop. • Disconnect the machine from the power supply; • Unscrew the nut (C in Figure 27).

Ice Frost Operator’s Manual OFF Condition In this condition, the electronic card is not connected to the power supply. To connect the ECU to the power supply, the main system switch must be put in the ON position.
Ice Frost Operator’s Manual Managing the Bowl Levels When one of the two level probes (SLIVx) fails to detect the presence of liquid in the bowl, the EVCARx is enabled to restore the correct level. The probes relating to each bowl are completely independent, therefore the following situation will occur: FIGURE 34 FIGURE 35 NOTE 1: The level/s refill phase must take place within a maximum time lapse which is controlled by the (controller (see Alarms chapter).
Ice Frost Operator’s Manual 3 seconds (software hysteresis) after the activation of the solenoid valve EVCAR 1, the safety signal is activated as the probe SSIC 1 has been identified as uncovered. The loading solenoid valve EVCAR 1 is therefore deactivated and the buzzer emits an intermittent signal lasting 6 seconds. NOTE 1: the same intervention methods are applied when the safety probe is uncovered after the solenoid valve EVCAR 1 has been activated.
