MAIN COMPONENTS

OPERATING PRINCIPLES
I
1 - CLEANING CYCLE
I
1.2 - Cleaning of the Plastic Trough (35).
The plastic trough (35) will reach its maximum lower position to discharge the water from the last cycle which was
interrupted by the shutdown of the Machine. This cleaning cycle is necessary due to safety and hygiene reasons,
because we could not quantify the time that the Ice Machine is turned off, with water inside the plastic trough (35).
1.1 - Initialization
Every time the machine is energized (connected to the power grid, switched on again by the tank's thermostat
(61) or after a power surge), the cleaning cycle for the plastic trough (35) and evaporator (20) starts up. The
signaling LEDs - LD1 (maintenance), LD2 (water shortage) - for the circuit board (62) and the LED board (68),
light up for a period of 02 seconds, in order to inform the start-up of the system's operation.
2 - ICE FORMATION CYCLE
2.1 - Formation
After the cleaning cycle, the plastic trough (35) returns to the highest position, the circuit board (62) switches on
the water valve (63) to let water in the the plastic trough (35), the mobile water sensor (55) indicates to the
circuit board (62) when the water level of the plastic trough (35) touches it, and switches off the water valve (63).
With the cooling system in operation, the formation of ice around the cube makers in the evaporator begins (20),
such cubes will grow to a thickness that obstructs the passage of the plastic fins (29) which rotate continuously.
3 - ICE DETACHMENT CYCLE
The purpose of the tank thermostat (61), whose bulb is fixed below the equipment's water draining tray, is to
switch the equipment off when it is filled with ice and turn it back on when the ice level in the tank (6) decreases.
In the EGC-50A model, the thermostat bulb is fixed in the tank. (6)
3.1 - “Quick Stop”
After 45 seconds, the circuit board (62), switches on the gear motor (60) to lower the plastic trough (35) and
discharge the residual water from the ice formation cycle. In this lowering interval, the plastic trough (35) will
perform a temporary stop, this action avoids the residual water - which is close to zero degrees - from reaching
the tank thermostat (61) and switching off the Ice Machine unnecessarily.
4 - OPERATION OF THE TANK THERMOSTAT
8
1.3 - Evaporator Cleaning (20).
With the plastic trough (35) at the lowest position, the gas solenoid valve (28) is activated for 45 seconds, cleaning
the evaporator from ice cubes.
3.2 - Ice detachment cycle.
With the plastic trough (35) positioned at the lowest point, the by-pass cycle begins. The circuit board (62)
switches on the gas solenoid valve (28), which allows the hot gas to enter directly into the evaporator (20),
detaching the ice cubes. After 45 seconds of By Pass, the circuit board (62) switches on the micro gear box (57)
for 5 seconds and checks whether the finned axis (50) is still blocked by any ice cube. If the finned axis (50) is
blocked, the by-pass time is increased by 5 more seconds, as often as needed, for up to 2 minutes. In case it is
unblocked, the circuit board (62) switches off the gas solenoid valve (28) and switches on the motor gear (60),
returning the plastic trough (35) to the highest point and restarting a new ice formation cycle.
2.2 - Growing cycle
When the ice cubes grow up to a thickness that prevents the rotation of the plastic fins (57), the micro gear
motor coupled to the finned axis (50) activates the end of cycle micro switch (59), indicating to the circuit board
(62) that the ice formation cycle is completed. In this moment, the circuit board (62), switches off the micro gear
motor (57). The system will wait for 10 seconds with the plastic trough (35) on the highest position, allowing
the residual water from the ice formation cycle to be used, increasing the volume of ice cubes and reducing the
volume of water discharged.
1.4 - The fan (24).
The fan (24) is activated through the micro switch (46). The micro switch (46) is fixated on the left panel of the
cylinder head (44), in a way that its rod is activated by the plastic trough (35). When the trough is lowered, the micro
switch (46) opens and it switches off the fan (24). This action assists the detachment of the ice cubes. When the
BYPASS is finished, the plastic trough (35) is elevated, the micro switch (46) is closed and the fan is switched on (24)

SCHEDULED MAINTENANCE
4 • The following items must be checked during scheduled maintenance:
A • Check and clean the screen of the water solenoid (63) valve.
B • Clean the gas condenser (25).
C • Clean the plastic trough (35) and the trough's water sensors (55 and 67).
D • Clean the ice tank (6), checking for incrustation or blocking, both in the draining tray and the tank's drain (6).
E • Check if the machine is leveled.
F • Check if the fan blade (24) rotates freely and if it is well balanced (there should be no vibrations when it is
operating).
G • Check if the finned axis (50) rotates freely , also observing gaps in the finned axis' bearings (41). (see p. 30
item 3.3)
H • Check the water level in the plastic trough (35). The level determines the size of the ice cubes. If you want to
increase or decrease cube size, verify item 3, sub-item 3.2, failure management, p. 30 (Adjustment of water level
and ice cube height) contained in this manual.
I • Check the wear of the sintered bronze bushings (32) on the plastic trough (35).
J • Check the filtering cartridge. When replaced, it should be by the same or similar model, in order to reduce the
corrosive effect of chlorine on the stainless steel, as well as ensuring the best quality of ice produced.
Before starting maintenance, unplug the machine and remove the machine's cover (1), except for
the EGC-150MA model.
For the EGC-150MA model: Remove the right side plate (16), loosen the fixation screws, open the frontal lid or
the right side plate (16).
1 • Maintenance and cleaning schedules are suggested to keep your equipment in good condition. Cleaning
varies especially depending on the location of the installation, water conditions and the volume of ice produced.
We recommend that maintenance be carried out every 6 months.
2 • The replacement of the power cord should only be carried out by the manufacturer. Authorized Technical
Assistance or a qualified professional, in order to avoid risks for the user and damage to your equipment.
3 • Filtering Cartridge Replacement.
Your equipment is supplied with an activated carbon filter. The service life of the filter is 6 months and it
depends on the quantity and quality of water passing through the filter cartridge, which aims at retaining
impurities, reducing chlorine, strange odors and flavors in the water, as well as minimizing the corrosive
effect of chlorine on the stainless steel. The filtering cartridge, which is located inside the filter, does not
allow cleaning after saturation, so it should be changed.
