4.Installation
Electrical connections
Electrical connections must be effected by a qualified technician. Install an outlet with main circuit
breaker and adequate fuses (see table 5).
Compressors must always be connected to the ground. The sections of the power supply line as shown
in the table are approximate and refer to a conductor with a maximum length of 50 meters. For very
long lines (more than 50 meters long) or in case of very high ambient temperatures, recalculate
the size of these sections.
WARNING:
The first time the compressor is switched on, check all the connecting clamps and tighten if necessary.
The compressor must only run with all parts of the cabinet closed.
Before connecting the compressor to the mains outlet, make sure that the factory mains voltage
corresponds to that of the compressor. Noncompliance may result in permanent damage to the
machine and will render the guarantee void. Before using the compressor, make sure that the supply
circuit is connected to the ground as specified by Presidential Decree 81/08 (or equivalent statutory
requirements applicable in each member state).
Connect the electro-compressor to the power supply by means of the electric cable that is provided.
Avoid the use of inadequate extensions, as these could impair operation. Never repair or modify power
supply cables or use cables that have been damaged or cut. Replace any cables that show signs of
wear with cables of the same type (available from authorised service centres).
Connection to the air supply
To connect the compressor to the compressed air system, only use hoses that are at least 60 cm long.
These must be of a suitable size in relation to the outlet on the compressor.
To ensure efficiency, the compressed air system must consist of a loop or closed-circuit in order to
reduce pressure drop to a minimum and make sure that the pressure along the entire line is as
homogenous as possible. Use suitably-sized seamless steel pipes (Mannesmann) or hoses made of
flexible materials that are suitable for use with compressed air. If metal pipes are used, these should
preferably have internal galvanized protection.
WARNING:
Hoses must have a diameter that is 1/2" bigger than that of the air outlet valves so that the relative
pressure drop does not affect compressor efficiency by reducing the minimum operating pressure,
which would undermine the efficiency of the whole system. Take care not to reduce the sections of
hoses or pipes along any part of the circuit, and use wide radius elbows to limit the amount of pressure
that is lost. Install a suitable number of air gate valves on the sump outlet and along the air supply
circuit to enable maintenance work to be carried out along the line. Make provisions for connecting an
emergency unit for use in case the primary compressor is not available. Use suitably-sized valves and
fittings in relation to the air outlet. The air supply circuit must have a slope of at least 1% in order to
drain any condensate that may deposit in the lowest parts of the circuit. Use the automatic blowdown
or purge valves on standard models to drain condensate [fig.8].
