NOTE:
- the hoses should be replaced every so often (every year or every 1000 hours) or when they show signs
of being scratched. For this purpose, check the number of operating hours of the hoses that are to be
disconnected (on the hour counter).
- The minimum radius of curvature of each hose must not be less than 250 mm.

3 The mains power supply should be provided with an effective grounding system. It is particularly
important to check that the earth resistance value complies with the protection and operating
requirements of the electrical installation of the compressor.
An effective machine earthing system is of fundamental importance for safety purposes.
Installation
4 Tighten the hoses to the machine with a
torque wrench setting of 15Nm (Fig. 41).
The compressor is supplied with an electric cable
and plug (4-pole 16A MCH 13-16/ET, 4-pole
32A MCH 26-32/ET) (Fig. 42).
1 For the electrical connection, the plug simply
has to be connected to a mains power
supply socket.
Before fitting the plug, make sure that the
installation has been set up in accordance with
the regulations in force in the country where the
compressor has been installed.
2 Also check that the details on the machine
rating plate are compatible with the mains
power supply, especially the nominal current
and input voltage.
