1.5 IDENTIFICATION
Data plate
The data plate contains the device's technical and perfor-
mance data. If lost, request another copy to the Technical
Support Service RIELLO.
Anything not allowing a safe identification of the product
such as tampering with, removal and missing of the Data
Plate could make any installation and maintenance ope-
ration more difficult.
1.4 SAFETY AND ADJUSTMENT DEVICES
Equipment safety and adjustment are obtained by checking
three distinct circuits:
• Cooling circuit
• Hydraulic circuit
• Electric circuit
The cooling circuit has a specific protection on the compres-
sor, a high pressure switch that is activated when the cooling
circuit pressure is too high and a low pressure switch in case
the value drops below a certain threshold.
The hydraulic system is provided with probes for the detection
of the delivery temperature and a safety valve that triggers
when water pressure exceeds 4 bar.
