INTRODUCTION Thank you for purchasing a ‘Spika Series’ Ice Cube Maker by ITV. You have purchased one of the most reliable icemaking products on the market today. Carefully read the instructions contained in this manual since they provide important information relative to safety during installation, use, and maintenance. 1.1. Warnings This device must be installed by a specialist technician. Any modification necessary to the electrical installation for the perfect connection of the machine must be carried out exclusively by professionally qualified and authorised staff. To guarantee the efficient and correct operation of this device, it is essential to follow the manufacturer's instructions, particularly with regard to maintenance and cleaning operations, which in most cases should be carried out by qualified staff. Actions by unqualified persons, apart from being dangerous, can cause serious faults. In case of a fault, contact the distributor who sold it to you. We recommend that you always demand original spare parts. Any use of the ice-cube-maker other than for producing ice, using drinking water, is considered inappropriate. Modifying or attempting to modify this device, apart from voiding the warranty, is extremely dangerous. The machine should not be used in the open air or exposed to the rain. Connect to the drinking water mains. The machine should be connected using the cable supplied. It is not designed to be connected to a fixed pipe. Always disconnect the machine from the mains before carrying out any cleaning or maintenance work. The electrical plug must be in an accessible place. We recommend the use of filtration in case of low water quality. Carry out unloading and recovery of materials or waste according to your national regulations on the matter. This device is not designed for use by persons (including children) with impaired physical, sensory or mental capacities, or who lack experience or knowledge, except if they have had supervision or instruction in the use of the device from a person responsible for their safety. Children should be supervised to ensure that they do not play with the device. 5 SERVICE MANUAL 1.2. SPIKA Reception of the machine Inspect the exterior of the packaging. If it is broken or damaged, complain to the haulier. To checky whether the machine is damaged, UNPACK IT IN THE PRESENCE OF THE HAULIER and make a record on the reception document, or on a separate document, of any damage that the machine may have suffered. Since 1 May 1998, it has complied with European regulations on the management of Packaging and Packaging Waste. Always record the machine and model number. This number is marked in three places: Packaging There is an external label with the factory number. Exterior of the machine On the back, on a label that is identical to the front. Name plate Check that the installation kit is complete inside the machine. It is consists of: ¾ gas connection, two filter joints, anchor bolts and the manual. CAUTION: THE PACKAGING ITEMS (PLASTIC BAGS, CARDBOARD BOXES AND WOODEN PALLETS) MUST NOT BE LEFT WITHIN REACH OF CHILDREN AS THEY ARE A POTENTIAL SOURCE OF DANGER 2. INSTALLATION 2.1. Placing of the ice maker This ice maker is not designed for outdoor operation. The icemaker should not be located next to ovens, grills or other high heat producing equipment. The SPIKA machines are designed to operate at room temperature between 5ºC (41ºF) and 43ºC (109.4ºF). There may be some difficulties in ice slab removal under the minimum temperatures. Above the maximum temperature, the life of the compressor is shortened and the production is substantially lower. The air cooled SPIKA NG (undercounter) ice makers take the air through the front section, and drive it off through the lateral, back and also front louvers due to their new oblique condenser structure and placement. Do not place anything on the top of ice maker or facing the front grille. In case the front grille is either total or partially obstructed, or due to its placement it receives hot air from another device, we recommend, in case it is not possible to change the location, to install a water cooled machine. 6 SERVICE MANUAL SPIKA The air cooled SPIKA MS (modular) ice makers take the air through the back section and drive it off through the two lateral louvers. In the case it is not possible to respect the minimum distances recommended (see the picture in point 3.3) for these machines we recommend to install a water cooled unit. The location must allow enough clearance for water, drain and electrical connections in the rear of the ice machine. It is important that the water inlet piping does not pass near sources of heat so as not to lose ice production. 2.2. Levelling of the ice maker Use a level on top of ice machine in order to ensure the equipment is perfectly leveled. Screw the leveling legs onto the bottom of the ice machine as far as possible. Move the machine into its final position. Use a level on top of the ice machine. Adjust each leg as necessary to level the ice machine from front to back and side to side. ATTENTION: There is an optional 3 ½'' (=90mm) high casters kit that can be used in substitution of the standard legs. These wheels are supplied with the corresponding installation instructions. 2.3. Installation of modular equipments on top of bins Modular ice makers should be installed on top of bins, following the instructions contained in this manual. The resistance and stability of the container-machine/s assembly should be verified as well as the fastening elements. Follow bin manufacturer instructions. 7 SPIKA SERVICE MANUAL 2.4.

Water supply connection The quality of the water supplied to the ice machine will have an impact on the time between cleanings and ultimately on the life of the product (mainly in water cooled units). It also will have a remarkable influence on the appearance, hardness and flavor of the ice. Local water conditions may require treatment of the water to inhibit scale formation, improve taste and clarity. If you are installing a water filter system, refer to the installation instructions supplied with the filter system. Use a flexible food grade hose. Pressure should be between 0.7 and 6 bar (10 and 85 psi ). If pressure overpasses such values, install a pressure regulator. ATTENTION: The machine shall be plumbed (with adequate backflow protection) according to applicable Federal State and local regulations. 2.6. Drain connection Drainage should be located lower to the machine level, at 150mm (5,9”) minimum. It is convenient that the drain hose is 30mm (1,18”) inside diameter and with a minimum gradient of 3cm/metre (0.36’’ / ft), see figure. Correct Incorrect Incorrect 9 SPIKA SERVICE MANUAL 2.7. Electrical connection It is mandatory to ground the equipment. To avoid possible electric shock on individuals or damages to the equipment, the machine should be grounded pursuant local and/or national regulations as the case may be. The manufacturer shall be held harmless in case of damages arising due to the lack of the ground installation. In case the supply cable is damaged, it should be replaced by a cable of special assembly to be furnished by the manufacturer or after-sales service. Such replacement should be performed by qualified technical service only. The modular units don’t have a cable with them. A qualified technical service must connect the power to the unit. The machine should be places in such a way as to allow a minimum space between the back and the wall to allow an easy access and without risks to the cable plug. Safeguard the socket. It is convenient to install adequate switches and fuses. Voltage is indicated in the nameplate and on the technical specifications section of this manual. Variation on voltage above the 10% stated on the nameplate could result on damages or prevent the machine start-up.

By default, the factory–set regulation covers a wide range of temperatures. 3.2. Start-Up Once the installation instructions are followed (ventilation, site conditions, temperatures, water quality, etc.), proceed as follows: 1. Open the water inlet. Verify the no existence of leakages. 2. For undercounter models open the door and remove the protection elements on the shield. For modular models remove the two locking screws on top of machine, take off the front panel and remove protection elements on the shield and also on the thickness sensor. 3. Verify that the shield moves freely. For modular models verify also the thickness sensor moves freely. 4. Connect the machine to the power supply. 5. For undercounter models: push the blue switch on the machine front side. For modular models: push the blue switch found on the back of the machine and then set the ice-wash switch to the position I. 6. Verify that there are no vibrations or frictions on the elements. 7. Verify that the water fall to the evaporator is occurring uniformly and all ice cubes are properly watered. 8. Close door (for undercounter models) / Replace the front panel in its place (for modular models). 12 SERVICE MANUAL SPIKA 9. Verify that after the final cycle, the frost on the aspiration pipe is at 20 mm (0.78 in) of the compressor. 10. For modular models: Verify the ice slab with the pictures below. In case the thickness sensor needs to be regulated, rotate the thickness adjustment screw CW to increase bridge thickness. Rotate CCW to decrease bridge thickness. For undercounter models adjust the cycle thermostat. Thickness sensor Damages due to the lack of maintenance and cleaning operations are not included on the warranty. 4. SEQUENCE OF OPERATION UNDERCOUNTER MODELS (NG) Initial Start-up: It’s recommended that the first time the machine is started (or the water tray has been emptied) it begins with the harvest sequence to ensure the water tray is filled. Freeze sequence: The compressor is energized. The timer G2 de-energizes the hot gas valve, so the evaporator begins to freeze. The timer G2 energizes the water pump so the water circulates from the water tray to the upper distributor, flowing through each cube cell, where it freezes. Harvest sequence: The compressor will continue energized. The timer G2 energizes the hot gas valve during a certain time. The timer G3 at the same time energizes the water inlet valve during a certain time to fill the water tray with the appropriate quantity of water. The ice slab slides off the evaporator and into the bin. After this, the freeze sequence starts again. When storage bin is full the stock thermostat detects a low temperature and the machine shuts off at the end of the freeze sequence. The ice machine remains off until enough ice has been removed from the storage bin and the stock thermostat doesn’t detect this low temperature. 13 SERVICE MANUAL SPIKA 5. SEQUENCE OF OPERATION -MODULAR MODELS (MS) Initial Start-up: The pump and the drain electrovalve are energized during 30 seconds to empty the water tray preventing the scale build-up in water. Then the pump and the drain electrovalve are de-energized, and the water inlet valve is energized filling the water tray until the water level sensor detects the water reaches the appropriate level. Then the freeze sequence starts. Freeze sequence: The compressor is energized and the water pump is energized after 30 seconds. The water inlet valve is also energized at the same time that the water pump to replenish water level and then de-energized. The compressor and water pump will continue energized until the thickness sensor detects the thickness of the ice slab is the appropriate. Then the harvest sequence starts. Harvest sequence: The compressor will continue energized. The hot gas valve is energized throughout the harvest phase to divert hot refrigerant gas into the evaporator. The water pump and the drain electro valve are energized during 45 seconds to empty the water tray and remove mineral deposits. After this (water pump and drain electro valve de-energized) the water inlet valve is energized filling the water tray until the water level sensor detects water reaches the level. The ice slab slides off the evaporator and into the bin. The momentary opening and reclosing of the shield indicates the harvest sequence has finished and goes to the freeze sequence. 14 SERVICE MANUAL 5.1. SPIKA Initial Start-up It is carried out at machine work start in following cases (being all outputs switched off): - when machine is connected to power supply. - when the switch is turned to the ICE position - after a stop due to full storage During start-up time t4 the pump (B) and the drain valve (EP) are activated. Subsequently, B and EP are closed and the water inlet valve (EW) is opened until the level sensor (NW) indicates that the storage reservoir is filled with water. At this point, the production phase starts. Please note: If at this stage the curtain (MC) is open, the indicated machine status is switched to full storage (full). Production Following outputs are activated: - Compressor (C). - Pump (B). It is activated with delay time t11. - Water inlet valve (EW). It is kept active during time t8, beginning with the start of B. This phase is maintained until the thickness detection sensor gives a signal (which is maintained during time t2). At this stage, the operation launching phase starts. Please note: during this time the opening of the curtain (MC) has no consequences. Operation launching Outputs: - Compressor (C). It is still in operation. - Hot gas valve (GC). It is active during the whole operation launching time. - Pump (B) and wast water valve (EP) are active during time t6 - Water inlet valve (EW) is activated when time t6 is over (when the pump is stopped) The operation launching ends when the ice sheet falls down and the curtain micro contact (MC) is activated. Two possibilities: 1) MC is active during a time less than t3 when the MC signal stops, the production phase will start. 2) MC is active during a time more than t3 machine will be stopped due to full storage (all outputs are switched off / LED LE3 continuously switched on). When the curtain (MC) is closed again, the initial start-up phase will be 15 SPIKA SERVICE MANUAL re-initiated. t1 t2 t3 t4 t5 t6 t7 t8 t9 t10 t11 t12 t13 5.2.

Below an example to calculate the proper quantity of sanitizer to add to the water, for household bleach 12,5%: bleachto add 15 15 1.2 gr/L *0.133 0.16 oz/gal %dis 12.5 12) Sanitize all surfaces of the ice thickness sensor, water level sensor, shield and water tray applying liberally the sanitizer solution using a cloth or sponge. 13) Sanitize the interior surfaces of the freezing compartment (including walls, plastic parts of the evaporator, distributor...) and the front panel applying liberally the sanitizer solution using a cloth or sponge. 25 SERVICE MANUAL SPIKA 14) Return the water tray and shield to their normal positions. 15) Connect power and water supplies. 16) To start a sanitation cleaning cycle, move the ice-wash switch to the WASH position. The machine will drain the reservoir and refill it. Pour the sanitizer into the water reservoir to get a solution as in the point 12 (the volume in the water tray is approximately 3 liters(0.8 gal) for MS 440) and 6 liters (1.6 gal) for MS 880 and 4,1 liters for MS 400/600 (0,9 gal)). 17) Allow the solution to circulate in the water system for 20 minutes and then set the ice-wash switch to the OFF position. 18) To purge out the sanitizer solution and residue move the ice-wash switch to the WASH position (drain and refill) and allow the water to circulate for 5 minutes and then move the switch to the OFF position (drain). Repeat this operation two more times to rinse thoroughly. 19) Return the panel to their position. 20) Set the ice-wash switch to the ON position (position I) and discard the first two harvests. 6.3. Cleaning the bins (for undercounter models) 1) Disconnect the machine, close water faucet and empty storage bin of ice 2) Use the cleaner/water solution to clean all surfaces of the bin. Use a nylon brush or cloth. Then rinse all areas thoroughly with clean water. 3) Use the sanitizer/water solution to sanitize all surfaces of the bin. Use a nylon brush or cloth. 4) Rinse with plenty of water, dry, run the machine and open water faucet. 6.4. Cleaning the condenser AIR CONDENSER 1) Disconnect machine and close water faucet. 2) For undercounter models remove the front grid by pressing the two clips placed at right side (see figure). For modular models remove the back panel (see figure). 26 SERVICE MANUAL SPIKA Front grid Back panel 3) Clean condenser using a vacuum cleaner, soft brush or low pressure air. Clean from top to bottom, not side to side. Be careful not to bend the condenser fins. WATER CONDENSER The water condenser may require cleaning due to scale build-up. The cleaning procedures require special pumps and cleaning solutions. They must be performed by qualified maintenance or service personnel. 6.5. External cleaning of the machine Clean the area around the ice machine as often as necessary to maintain cleanliness. Sponge any dust and dirt off the outside of the ice machine with mild soap and water. Wipe dry with a clean soft cloth. A commercial grade stainless steel cleaner/polish can be used as necessary. 6.6. Water leakage checking This must be done whenever maintenance is carried out on the machine: check all water connexions, braces, tubes and hoses in order to eliminate leaks and prevent breakages and flooding. 27 SERVICE MANUAL SPIKA 7.
