RESIDUAL RISKS AND HAZARDS THAT
CANNOT BE ELIMINATED
IMPORTANT!
Pay the utmost attention to the signs and symbols
located on the appliance.
Indelible safety instructions have been affixed identifying the potentially
dangerous parts if risks are still posed by the unit, which cannot be
technically eliminated, despite all the precautions taken during the
design phase. The warning labels must not be removed for any reason
whatsoever. A new label must be duly requested from the Spare Parts
Service if it should no longer be legible after having used, for example,
aggressive detergents.

I.8.2
High and low pressure switches.
DANGER!
The pressure switch is a safety device which
complies with standards in force. If tampered with
and/or modified, it could determine personal
danger.
The unit is equipped with two pressure switches for each individual
circuit. This device monitors two distinct functions:
High pressure switch:
it trips to prevent working pressure from rising
excessively in the refrigeration circuit.
Low pressure switch:
it monitors so that the low pressure side does
not drop below a certain value.
I.8.3
High and low pressure gauges (GM
accessory)
High pressure gauge:
indicates the high pressure value.
Low pressure gauge:
indicates the low pressure value.
