4.1.4 DEFROSTING

The machine carries out defrost cycles at intervals pre-set by the manufacturer.
If under specific operating conditions (very hot or humid periods of the year, the introduction of products that releases a great
deal of moisture, or frequent door opening .....), the set defrost cycles are insufficient for the complete removal of ice from the
evaporator, additional "manual" defrost cycles can be carried out. Press DEFROST button d for more than 5 seconds in order to
start a "manual" defrost cycle, which will begin only if conditions require it.

4.1.5 SWITCHING ON THE COLD ROOM LIGHT

Press the cold room light button to switch on or switch off the cold room light.
When the light is switched on, the pilot light alongside the button will light up.

4.1.6 STOPPING THE MACHINE

To stop the monobloc, it is sufficient to use the main switch . If the machine is to remain switched off for long periods, it is advis-
able to disconnect it from the main power supply.

4.2 ALARMS AND SIGNALS

The control panel is equipped to display error messages (Alarms) using the DISPLAY and the ALARM led .
The following is a list of possible messages:
SIGNALS OF ALARM
" AH1 " : High temperature alarm (referring to room probe or probe 1)
" AL1 " : Lew temperature alarm (referring to room probe or probe 1)
" AH3 " : High temperature alarm (referring to probe 1)
" Ad2 " : Defrosting time dout
" Opd " : Door Open Alarm
" PA " : General pressure switch alarm
Press any button to silence the allarm. The LED will start to blink
SIGNALS OF DEFECT FEELER
" E1 " : Faulty probe 1 (thermostat control)
" E2 " : Faulty probe 2 (evaporator)
" E3 " : Faulty probe 3 (condenser)
- If simultaneous, they will be shown on the display alternately every 2 seconds.

4.3 SAFETY PRESSOSTATS

In some machines it is estimated the injection of safety pressostats. This pressostats are installed in the circulation of refrigeration
to reveal low pressure and high pressure. This can be done manually or automatically.
The first ones install themselves automatically based on the state of work of the machine. The second ones have to be installed by
a qualified technician for the reset of the pressostats. The releasing causes of the pressostats are:
- the presence of tube-blocking elements
- the presence of influencing air inside the refrigeration-gas system
A temperature alarm has been fitted. This is signalled by the ALARM led , which light up when the temperature in the cold
room undergoes a large variation beyond the limits set above or below the "set point".
CAUTION !!! To disable an alarm condition, press the FNC button .
CAUTION !!!
The "PA" pressurestat error causes the machine stop. To restart the machine, it is necessary to switch off and
switch on the power supply. If the error persists, contact the Technical Support Service.
