USE
During normal operation, the instrument displays the temperature measured by the probe placed in the refrigerated area (display case tank/top or
compartment).
To view the current setpoint (selected temperature), press and release the set button; when the "set" message appears, press the set button again.
To change the working setpoint, press and release the set button. When the "set" message appears, press the set button again. The set value will
appear and to modify this, use the ▲(2) or ▼(3) push buttons within 15 seconds to increase or decrease the value; after this has been changed,
press the set button again to save the value.
The setpoint can be set within the established minimum and maximum temperature limits.
The defrost function can be activated at any time by pressing the ▲ (2) button for at least 5 seconds; the next automatic def rost will start when the
defrost interval time set by the manufacturer has elapsed.
WARNINGS AND ALARMS
"E1" on the display indicates that the thermostat probe is faulty which could be caused by one of the following malfunctions: incorrect type of tank probe,
faulty tank probe or faulty connections; check the condition of the probe and that the connection between the instrument and probe is correct.
"AH1" on the display indicates the high temperature alarm meaning that the value read is greater than the set max. value after the pre-set time; it does
not affect the regulation in any way and the alarm will cease when the temperature falls below the max. value.
"AL1" on the display indicates the low temperature alarm meaning that the value read is lower than the set min. value after the pre-set time; it does not
affect the regulation in any way and the alarm will cease when the temperature rises above the min. value.
The thermostat's factory-set configuration parameters must only be modified by qualified personnel using the instrument's instructions.
Should any anomalies occur (short circuits, mechanical failures, electric cable deterioration, a smell of gas indicating a possible leak, etc.), the person
in charge of normally operating the machine must immediately switch off the appliance, unplug it from the power mains and secure the work area.
7.4 Total shutdown
When the unit is to be decommissioned for a lengthy period, the following measures must be taken:
•
Turn off the main switch.
•
Disconnect the upstream power supply.
•
Remove all the food from the refrigerated counters and clean the inside as well as all the accessories.
•
Leave the refrigerated counters doors ajar so that fresh air can enter and prevent undesirable smells from forming.
•
Protect the stainless steel surfaces with a thin layer of Vaseline oil. To do this, soak a cloth in the oil and rub vigorously.
•
Periodically air out the premises.
8. CLEANING AND MAINTENANCE
8.1 Routine maintenance
The appliance must only be cleaned after the power supply upstream from the appliance has been disconnected.
During the maintenance operations, the cable and the plug must be always visible and accessible for the operator who is performing the operations.
The routine and preventive maintenance essentially entails cleaning the stainless steel parts with warm water and mild soap on a weekly basis, and then
rinsing and drying these thoroughly. Do not use direct jets of water. We recommend cleaning the fins of the refrigerating unit's condenser at least every
three months. These operations must be performed by qualified personnel.
WARNING:
•
Under no circumstances should you use abrasive or corrosive cleaning products.
•
Do not accelerate the defrosting process using utensils such as scourers, brushes or sharp metal scrapers.
•
Bleach, hydrochloric acid and other compounds containing chlorine will damage the stainless steel.
•
The coloured parts must be cleaned with silicone wax.
•
The floor under the appliance must not be washed with corrosive substances that could produce appliance-damaging vapours.
•
When cleaning, do not wash the appliance with jets of water.
•
The polycarbonate doors must only be cleaned with alcohol and a soft cloth.
•
WARNING: Do not damage the refrigerant circuit.
•
It is forbidden to remove the safety guards.
•
It is forbidden to use open flames to check for gas leaks.
•
Smoking is prohibited.
