Carefully read the instructions contained in this manual since they provide important information
relative to safety during installation, use, and maintenance.
1.1. Warning
The installation of this equipment should be done by a qualified technician.
The socket should always be placed on an accessible location.
Always disconnect the power supply from the machine before any cleaning or maintenance
service.
Any change needed on the electrical installation for the appropriate connection of the machine,
should be exclusively performed by qualified and certified professional personnel only.
Any use of the ice maker not intended to produce ice, using potable water, is considered
inappropriate.
It is extremely dangerous to modify or intend to modify this machine, and will void warranty.
This machine should not be used by children or handicapped without the proper supervision
and monitoring.
This machine is not intended to be used outdoors nor exposed to the rain.
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 order to assure the proper operation and efficiency of this equipment, it is of paramount
importance to follow the recommendations of the manufacturer, especially those related to
cleaning and maintenance operations, which should be performed by qualified personnel only.

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 41ºF (5ºCF) and
109.4ºF (43ºC). 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 (under counter) 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.
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
installing 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. Leveling of the ice maker
Use a level on top of ice machine 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.

SERVICE MANUAL SPIKA SERIES

2.3. Installation of modular equipment 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.
2.4. Minimum distance to obstacles
Please see below the recommended minimum distances for proper operation and efficient
service.

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 14 and 85 psig (1 and 6 bar). 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 5.9” (150mm) minimum.
It is convenient that the drain hose is 1,18” (30mm) inside diameter and with a minimum
gradient of 0.36’’ / ft (3cm/metre), 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 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.

Damages due to the lack of maintenance and cleaning operations are not included on the
warranty.
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 under counter 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 under counter 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 under counter models) / Replace the front panel in its place (for modular
models).
9.- Verify that after the final cycle, the frost on the aspiration pipe is at 0.78 in (20 mm) 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 under counter models adjust the cycle
thermostat.

4. SEQUENCE OF OPERATION UNDER COUNTER 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 electro valve are energized during 30 seconds to
empty the water tray preventing the scale build-up in water. Then the pump and the drain
electro valve 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, opening first during 5” the hot gas valve to equilibrate.
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

SERVICE MANUAL SPIKA SERIES
14
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.
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 hot gas
valve opens for a time t20, and then the production phase starts. LE1 on
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, if the water level (NW) is not
reached the water valve (EW) will keep open (even after the time t8) until the water level probe
(NW) detects water tray full.
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.
*LE1 on
Please note: during this time the opening of the curtain (MC) has no consequences.

SERVICE MANUAL SPIKA SERIES
15
Harvest
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)
*LE1 on
The harvest 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 re-initiated.

5.3. Alarms
They detect operational malfunctions. They are indicated with the flashing status LEDs LE1-4.
During some alarms a second operation retry attempt is carried out and if repeated again, the
machine will stop. Signaling should be indicated since the first failure occurs. If the second retry
attempt is ok, the signaling must be switched off.
In case that a machine stop has been caused by alarm, the resetting is done by disconnecting
or by switching over to position 0. If the dip-switch 2 ON, time alarms are not to be followed.
5.4. Safety pressure
When the pressure contact (P) is open, instantly, all outputs switch over to off position.
When it is closed again, there are two possibilities:
- Dip-switch 1 OFF. Manual reset. The machine remains stopped until reset Initial start-up.
- Dip-switch 1 ON. Automatic reset. The machine will stop for a time t5, then continue at the
position where it was, except during the harvesting phase, that has an initial start. If starts at
fabrication, the hot gas valve will open during time t20 before starting the compressor.
* Signaling: Flashing in the four LEDs.

5.5. Long operation
If the operation launching time is longer than t5 time without activation of the curtain micro
contact (MC), the launching is interrupted, switching over to the production cycle. If the same
thing happens again at the next launching, the machine will stop.
* Signaling: Flashing in LE0.
5.6. Cycle timeout
If the production cycle time is more than t10 time without receiving any thickness detector signal
(ESP), the next launching phase will be started. If the same thing happens again at the next
launching, the machine will stop. * Signaling: Flashing in LE1.
5.7. Short production cycle
If during two consecutive cycles the production cycle time is less than t7 time, the machine will
stop. * Signaling: Flashing in LE2.
5.8. Water filling timeout
When it occurs, the water valve (EW) must be activated, the level sensor (NW) will not be active
during a maximum time t9.
Two possibilities:
- Dip-switch 4 OFF Machine stops and when a time t13 has passed it starts the unit if th
switch 3 is in Ice position (I). If it is in clean position (II) the cleaning will start again. If in a time
t9 the water level probe (NW) does not detect water, the unit will stop until a reset.
* Signallng: Flashing in LE3.
- Dip-switch 4 ON To be used in places with low water pressure. After a time t9 with no
water detection, the unit turns off the compressor C, water pump B, hot gas valve GC and drain
valve EP. The inlet water valve EW keeps on, and the water level probe (NW) keeps waiting for
the water detection. When the water is detected (water tray filled), the alarm signaling will turn
off (LE1+LE2 alternative blinking), and it will continue as follow:
Initial start up with SW4 ON
oAfter a time t9 with no water detection, LE1+LE2 will flash indicating alarm.
oInlet water valve (EW) will keep on, and the water level probe (NW) will remain
active.

SERVICE MANUAL SPIKA SERIES
19
oThe compressor (C), hot gas valve (GC), water pump (B), and drain purge (EP)
remain off.
oWhen the water is detected, fabrication will start, and the LE1+LE2 alarm will stop.
Fabrication after a start up with SW4 ON
oThe compressor (C), hot gas valve (GC), water pump (B), and drain purge (EP)
remain off.
oInlet water valve (EW) will keep on, and the water level probe (NW) will remain
active.
oWhen the water reaches its level and the water level probe (NW) detects it,
LE1+LE2 will stop flashing, and the water inlet valve (EW) closes. The hot gas
valve (GC) will open for a time t20 before the compressor, then the compressor
(C) starts, and after a time t11 the water pump (B) starts. The drain valve (EP) will
remain closed.
oAs the normal fabrication phase (SW4 OFF), during a time t8, the water level will
be checked with the water probe (NW), if no water is detected, the water inlet
valve (EW) will remain open (even after the time t8) until the water level probe
(NW) detects the water.
oIf after a time t8 no water is detected, and the time t9 has passed, the unit will not
stop, the water inlet valve will close and the unit will keep going into fabrication
mode.
oAs the normal fabrication phase (SW4 OFF), this phase will be active until the
thickness sensor probe will give a signal (maintained during time t2). Then the unit
will go into harvest.
*NOTE: The minimum time for the compressor to be off is t19, in case that the water is detected
before a t19 time since the compressor has turned off, the hot gas valve (GC) and the
compressor (C) will not turn on again until the t19 has passed by.
Suction temperature probe
Green LED: it will light when the temperature is lower than T1.
If the probe is broken or not connected: the green light will flash. The unit will not use the probe,
works as usual.
The probe will work during harvesting. Since the pump (B) starts until the hot gas valve (GC)
opens. In case that after a time > t18 with a temperature lower than T1 the alarm will turn on.
After an alarm occurs, the unit will stop immediately, a reset is need it. LE0+LE1 alternate
flashing.
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 jumper with the indication:

SERVICE MANUAL SPIKA SERIES
20
- Closed jumper upper machine
- Open jumper 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,

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.
