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.

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.

2.5. 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.

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.

NOTE: The thermostat regulation may vary depending on the ambient temperature of water and on the place
where the machine has been installed. 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).

SERVICE MANUAL SPIKA
13
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.
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.

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 re-
closing of the shield indicates the harvest sequence has finished and goes to the freeze sequence.

SERVICE MANUAL SPIKA

5.1. 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

- Dip-switch 4 on →Machine stops and once time t13 has passed, the startup is re-initiated. .
* Signaling: Flashing in LE3.
5.9. Machine Stacking
It is possible to install two modular machines stacked one above the other with the ITV MS stacking kit (part
number 6586).
The switchboard must have a connector permitting to connect the boards of both machines with a single cable
and also a dip-switch with the indication:
- Dip-Switch 5 on upper machine
- Dip-Switch 5 off lower machine
The lower machine works in the same way as if operating alone.
The upper machine operates normally except when the lower machine is stopped due to full storage (full), at this
moment, the upper machine will also stop and pass over to the same status (full).
When the curtain of the lower machine is closed again, it re-initiates the start-up sequence, likewise the upper
machine, but with a 1’ delay.

6. MAINTENANCE AND CLEANING PROCEDURES
It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition.
Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. This
chemical dissolves mineral build up that forms during the ice making process.
Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned
and sanitized.
The ice machine’s water system should be cleaned and sanitized at least twice a year.
CAUTION: Do not mix Ice Machine Cleaner and Sanitizer solutions together.
WARNING: Wear rubber gloves and safety goggles when handling Ice Machine Cleaner or Sanitizer.
WARNING: Unit should always be disconnected during maintenance/cleaning procedures.
6.1. Cleaning water distribution system for undercounter models (NG)
a) Set the switch to the OFF position after ice falls from the evaporator at the end of a harvest cycle, or set
the switch to the OFF position and allow the ice to melt off the evaporator.
CAUTION: Never use anything to force ice from the evaporator.
b) Remove all ice from the bin.
c) Remove the back metal lid and the top panel (if it need be to make easier the cleaning operations).
