ADVICE FOR THE INSTALLATION OF SCALA 3000 COMPACT
STEP 1: LOCATION OF THE ICE MACHINE
•Needs an electricity commenction: 1 three phase socket 5+TTx6 mm2. Install differential
and thermal in the main frame (32 amps, consumption 14870W).
•Water supply: needs a nearby tap for water inlet. ¾”.
•Outlet: The unit has an overflow tube, to prevent water from entering the evaporator
drum, in the event of failure of the filling buoy. Needs to have an outlet drain nearby.
The drain pipes of the unit should not be siphoned at any time, the water should drain
without problems. In addition, there is a shut-off valve with tap for emptying the water
tank. 21 mm diameter or 38 mm diameter depending on the unit.
•The machinery must be hoisted with care not to move the gear motor on the
evaporator. Use a lift or crane with straps using the unit's base.
•Keep in mind that the air enters through the condenser front and exits to the area of
the compressor. Have good ventilation in the location of the unit.
•Level the unit correctly.

Step 2: INSTALLATION REMOTE ELECTRICAL CONTROL BOX (TO BE INSTALLED IN SILO
CHAMBER)
The remote box lets you control the unit from the silo chamber. It has a switch to start/stop the
ice maker, and another to start/stop the water evaporator (cooler). In addition, it has LEDs
indicating:
•Reducer gear
•Full of ice
•Cooler gear
•Thermal reducer failure
•Thermal compressor failure
•Lack of water
Remote box
For the connection, a signal cable is required, 12x1 mm2. The cable is connected to the
terminal board of the remote panel, and from there to the terminal board in the box of the
condenser unit of the generator (12 terminals).

In addition, there are two outputs to power the cooler (evaporator), which is located in the
chamber, upper part, to cool the water that goes to the generator. Use a 3x1.5 mm2 cable
to feed.

STEP 3: PLUMBING INSTALLATION
The ice generator has a ¾” water inlet, ready to connect the water supply network. In the
installation is included a cooler (evaporator) to to be placed in the silo chamber, and to reduce
the inlet temperature of water to the unit. This cooler has only one fan that is connected to the
start/stop of the remote panel.
To install the cooler, we recommend making a bypass system to be able to cancel it if necessary.
Below we show photos of an installation for two Scala 3000 units.

Cooler housing
The water tank has an upper overflow pipe, to avoid possible overflow of water (float valve),
as well as a key in the lower part for emptying the water tank. It is advisable to install a drain
for the overflow and the drainage outlet for the tank.
Keep in mind that the unit always uses the water in the tank to produce, and in normal
operation, does not lose water.

STEP 3: INSTALLATION OF PIPE FOR ICE DROPPING TO SILO
The ice comes out through the circular opening of the evaporator and falls by gravity. Being sub-
cooled flake ice, from -5ºC to -7ºC, with a thickness of 1.2 mm to 3 mm, it inclines to come out
(by the rotation of the milling cutter that causes the ice to fall from the evaporator wall). You
have to make a drop to drive the ice into the box.
It is usually a hopper outlet and then flow into the silo. It can be in stainless or food PVC.
The drop must have an adequate slope, so do not make an exit of more than 30% to prevent the
ice from caking.
Below are photographs taken in a stainless installation.

STEP 4: INSTALLATION STOP PHOTOCELL
The unit has a remote stop photocell, which can be installed in the chamber, to stop the ice
falling (if the fall is completely conducted, it is not necessary, since it stops just below the
evaporator, which has the stop photocell for full of ice).
Here is how the photocell connects. A 5x1 mm2 hose is needed to feed the photocell and the
signal, from the location of the photocell to the electrical panel of the ice generator.

Position the switch as indicated in the figure
–Adjust the TIME selector to the minimum until it stops in anti-clockwise rotation
–Adjust the operating distance with the SENS selector
–Put an object at the desired distance
If the sensor does not detect the object (LED ON)
–Turn the SENS selector clockwise until the LED light goes off
–Turn the SENS selector slightly counterclockwise until the LED lights up
If the sensor detects the object (LED OFF)
–Turn the SENS selector counterclockwise until the LED lights up
–Remove the object
Adjust the TIME selector two stripes clockwise past the MIN

STEP 5: STARTING UP
•Start the unit. It comes with a control panel, with a delayed start of 3 minutes for safety.
After 3 minutes, the water pump starts up, the reduction motor starts and the liquid
solenoid valve opens, then the unit starts.
•The evaporator panel comes with a speed variator, which allows modifying the
frequency of rotation of the motor, allowing speeds below 50Hz (factory parameter)
achieving thicknesses greater than 1.5 mm and up to 3 mm. The production loss is not
more than 20% at a speed of about 30 Hz. We do not advise lowering more than 30 Hz.
•The variable speed drive also has the function of heat gear motor. It is responsible for
stopping the same in case of overloading of the engine.
