2. Overview
Read this service manual carefully before installation, debugging and operation of this ice machine.
This Service Manual gives an introduction of operation conditions, performance parameters, installation and debugging and
operating procedures of SCALA - SC ice machines.
The ice machine system is of vertical, internal ice scraping type.
The machine is equipped with P.C. board, which exercises monitoring over its whole operation process, namely:
(1) Ice level
(2) Water level in water tank
(3) Normal operation of reducer’s electromotor
(4) Temperature of condenser
In addition, the P.C. board will protect the machine when any abnormal condition arises and in the meanwhile, an alert indicator
lights up to indicate the cause of stoppage, thus facilitates the trouble shooting and maintenance.

Waste Disposal.
Be sure to include model name and serial number on all claims. Serial number is located in the following three places:
1) Packing
There is a label stuck onto the cardboard packing bearing this serial number (1).
2) Machine body
On the back of the machine (1).
3) Machine body
Located at the back of the machine, rating plate.
Verify that the installation KIT is inside the bin, and has the following pieces:
. 3/4’ water hose, two small filters and user manual.
. Dischareg hose.
(1)
WARNING: DO NOT LEAVE PACKING MATERIALS (PLASTIC BAGS, CARDBOARD BOXES, ETC.) WITHIN
REACH OF CHILDREN.
INSTALLATION
1. Recommended Placement of Unit
Sockets and wiring must comply with local standards for electrical appliances and requirements set forth on the rating plate of
the machine.
Air switch must be installed within an immediate touch and shall be chose in line with the current of various types of machines,
and earth wires shall be installed in assigned position on the baseboard or in the electric case according to relevant standards.
Continual water supply shall be guaranteed for the machine (Pressure is at 1.5 to 6 Bar) and water supply switch shall be
mounted near the ice machine. Inlet pipeline shall be of independent type and drainage outlet shall be also not far from the ice
machine. Two separate water drainage pipelines shall be required for draining the ice machine and the ice storage bin.
The ice machine shall not be placed in an airproof environment, next to heat sources, or outdoors.
To ensure ice quality, personnel responsible for installation shall be consulted about whether or not water filter or processor shall
be installed according to user’s local water-quality conditions.

2. Installation procedure
The ice-maker shall be lifted using the four shackles fixed on its base plate (for small-sized machine) oron its top (for large-sized
machine) and shall be laid down slowly on the support or ice storage bin that has been put in place.
For large-sized ice-maker, the correct steel cable lifting is as shown in this figure.
CORRECT LIFTING WRONG LIFTING
OPERATION
1. Preliminary Checks
a) Is machine levelled?
b) Are voltage and frequency of mains supply the same as indicated on rating plate?
c) Is drainage system working properly?
Minimum value Maximum value
Ambient temperature 5º 40º
Water temperature 5º 35º
Water pressure 1,5kg/cm2 5kg/cm2
Desviation from voltage rating -10% 6%
NOTE: To install a pressure reducer If water inlet pressure is more than 6 Bar.
ATENTION:
Check that voltage and mains frequency is the same as in the rating plate.
2. Starting up
Open feed water valve and fill up the water tank, and the floating valve automatically closes when water level reaches the
spillover port.
During trial operation, pneumatic mains switch (K1) shall be turned to “ON”, then the power indicator on the panel of electrical box
(see Figure 5). Switch on the Start/Stop button on the electrical cabinet to enable the ice-maker to enter a 3-minute-delay state
(indicator of Start Delay blinks) which is followed by the automatic start of gear box and water pump by the control system, and
then the machine goes into operation. Observation shall be conducted at this time to verify that (1) ice blade is rotating in correct
direction or the shaft and rotation is in normal status; (2) water dispensing disc is aligned with the red mark and water-dispensing
pipes have normal output. In case above-stated items are all in normal operation, the Start/Stop button shall be switched off to
stop the ice machine. (3) Ice production stage: Start refrigeration system and open return air valve and Freon feed valve.

H
3. Stop
When the “Start/Stop” button is switched off, water pump and solenoid valve stop working immediately, and the gear box stops
working too after a 3-minute delay so as to remove the ice left on the interior of the vaporization cylinder. Now the pneumatic
switch shall not be turned off before being delayed for 3 minutes.
Stoppage due to alarm
Stoppage due to ice full level alarm (normal stop):
When microprocessor of computer’s main board detects full level of ice storage tank, the programmed process of ice full level
shall be implemented: water pump and solenoid valves stop first, and then gear box motor stops after 3-minute delay and ice full
level indicator turns on at the same time. Now the system is in stand-by mode. After ice is discharged, the system automatically
restore to normal operating status: gear box motor, water pump and solenoid valve will be started in sequence.
IMPORTANT!
ADVISE THE FINAL USER ON MAINTENANCE PROCEDURES WHICH ARE NOT INCLUDED IN WARRANTY, AS WELL AS
THOSE BREAKDOWNS CAUSED BY NEGLECT OF PROPER MAINTENANCE PROCEDURES.
MAINTENANCE AND CLEANING INSTRUCTIONS
IMPORTANT!
**Maintenance and cleaning procedures as well as problems derived from failing to carry them out are not covered by the
warranty.
Proper maintenance is essential to obtain favourable ice quality and optimum functioning of unit.
Frequency depends on water quality and characteristics of room where unit is installed.
** Maintenance/cleaning procedures should take place at least once every six months. If concentration of air pollutants is high,
complete procedures on a monthly basis.
Important Maintenance for Removable Electromagnetic Valve (See Figure9 and Figure10)
1. During the preliminary stage of ice production (Approx one-week or one month), cleaning for Electromagnetic valve
shall be carried out by well-trained (or professional) maintenance staff to avoid solenoid core, fore-guide valve hole
and piston from being block or stuck. Before dismantling and cleaning the solenoid’s pipeline, the refrigerant in
it shall be completely discharged.
2. Tap water quality shall be guaranteed and periodic cleaning shall be carried out for water tank and feed water
pipelines to ensure smooth access of water system, and all pipe fittings shall be free of leak.
3. Regular inspection shall be carried on the level of water dispensing pan, which shall be in line with the red mark, and
can be regulated by the water valve beside the water dispersing pan, and on the status of water outflow to prevent
water from dripping into ice storage tank or ice conveying system.
4. Regular inspection shall be conducted on the connections to verify they are not loose or dummy connections, and
earth wire is fixed, insulation of electrical parts not damaged.
5. Frequent inspection on refrigeration pipelines and valves shall be conducted to identify their leakages and loosing or
leaking at flange fittings.
6. Good housekeeping shall be maintained for main parts of ice machine like gear box and control cabinet
7. Regular inspection on ice blade spacing shall be conducted. Too big spacing between ice blades will affect the
removal of ice.
8. Lube oil for gear box shall be checked and changed on a regular basis
9. Maintenance and use of valves.
Regular application of rustproof oil shall be carried out on surface of valve rod and lock nuts to ensure smooth diverting and keep
valve rod and seal free of damag.
