8 UNPACKING

9 UNPACKING The machines are supplied in a carton box secured by two plastic strips to a wooden base. Check first the outside conditions of carton box and wooden base then cut the two plastic strips, remove the tape and then the carton box.

10 Visually inspect the exterior of the machine then open the bin door and remove from the inside the: water supply inlet tube water outlet tube leg kit (on ICEU 85 only). UNPACKING

11 UNPACKING Remove the adhesive tape securing the spray platen assembly to the front of the water sump.

12 INSTALLATION

13 INSTALLATION Check the data plate of the machine located on the rear panel for correct voltage as well as for the proper wiring/fuse size. Remember that all machines require a solid earth wire.

14 INSTALLATION Check for the correct water and ambient conditions that should be: Min. ambient temperature 10ºC (50F) Max. ambient temperature 40ºC (100F) Min. water temperature 5ºC (40F) Max. water temperature 35ºC (90F) Min. water pressure 1 bar (14 PSI) Max. water pressure 5 bar (70 PSI)

15 INSTALLATION Adequate space must be left for proper water and electrical connections on the rear side of the machine. A minimum clearance of 15 cm on both sides for best routing air. Min. space 15 cm

16 INSTALLATION - AIR CIRCULATION COLD AIR Fan Motor Condenser HOT AIR Compressor Control box

17 INSTALLATION Installation under counter with no space of both sides are allowed but daily ice capacity can drop down to a maximum of 20%.

18 INSTALLATION Level the unit on both directions front to rear and right to left side using the adjustable legs.

19 INSTALLATION - ELECTRICAL Install, on the cable supply with the machine, an adaguate electrical plug according to the local standards and regulations. Maximum voltage variation should be ±10%. Machine must be individually fuse protected.

20 INSTALLATION - WATER IN Connect the water inlet 3/4 male threat of the water inlet solenoid valve to the water supply line by means of the rubber hose provided with machine. Install on water supply line closed to the machine a water valve (tap).

21 INSTALLATION - WATER DRAIN Connect the 20 mm O.D. fitting of the water drain with the flexible hose supply with the machine securing by its proper clamp.

23 START UP AND OPERATIONAL CHECKS

24 START UP AND OPERATIONAL CHECKS Open the water tap/valve. Switch ON the power on the electrical supply line.

25 START UP AND OPERATIONAL CHECKS Move the Cleaning Switch on the Cleaning - II position.

26 START UP AND OPERATIONAL CHECKS By doing so, both the water and hot gas solenoid valve are energized together with the water pump and fan motor. SAFETY THERMOSTAT BIN THERMOSTAT EVAPORATOR THERMOSTAT CLEANING SWITCH COMPRESSOR WATER INLET VALVE HOT GAS VALVE WATER PUMP FAN MOTOR

27 START UP AND OPERATIONAL CHECKS The components energized during this period are: Water Inlet Solenoid Valve

28 START UP AND OPERATIONAL CHECKS The components energized during this period are: Water Inlet Solenoid Valve Hot Gas Solenoid Valve

31 START UP AND OPERATIONAL CHECKS The Ice Machine will start up charging water till the water sump is filled up till the overflow stand pipe.

32 START UP AND OPERATIONAL CHECKS The water goes through the Water Inlet Valve then..flows into the small orifice of the Flow Control located on the outlet port of the same.

33 START UP AND OPERATIONAL CHECKS Following the copper inlet tube the incoming water arrive on the upper side of the evaporator.... where it flows onto the plastic evaporator platen dribbling down through the holes located on the corners.

34 START UP AND OPERATIONAL CHECKS Dribbled water is collected down, through the evaporator housing..

35 ACCENSIONE E VERIFICHE FUNZIONALI.into the water sump where is located the overflow hole ( ON THE ICEU MODELS) that assures the proper water level and quantity for the next freezing cycle, or... ICEU 45-65

36 START UP AND OPERATIONAL CHECKS...into the water sump where is located the overflow stand pipe for the model ICEU 85. ICE-O-MATIC ICEU 85

37 START UP AND OPERATIONAL CHECKS As soon as the water sump is full and water is going through the drain, move the Cleaning Switch on the Operating - I position.

38 START UP AND OPERATIONAL CHECKS The machine start up now in the freezing cycle with the following components in operation. SAFETY THERMOSTAT BIN THERMOSTAT EVAPORATOR THERMOSTAT CLEANING SWITCH HOT WATER FAN GAS PUMP MOTOR COMPRESSOR WATER VALVE INLET VALVE

39 START UP AND OPERATIONAL CHECKS Compressor

40 START UP AND OPERATIONAL CHECKS Compressor Water Pump ( ICEU ) Water Pump ( ICEU 85 )

41 START UP AND OPERATIONAL CHECKS Compressor Water Pump Fan Motor (on air cooled version only)

42 START UP AND OPERATIONAL CHECKS Water is circulating by the water pump into the inverted tin plated copper molds of the evaporator.

43 START UP AND OPERATIONAL CHECKS.while the refrigerant is flowing into the serpentine welded on the upper side of the tin plated copper molds.

44 START UP AND OPERATIONAL CHECKS Few minutes after the start up of the freezing cycle, the temperature of the evaporator serpentine is very cold with a larger extension of frost around the same.

45 START UP AND OPERATIONAL CHECKS The machine remains in the freezing cycle for an average time of minutes (supposing an ambient/room temperature of 21ºC) till the evaporator thermostat reach its Cut In temperature of -25ºC. <-25ºC
