In order to use the compressor in complete safety read the safety standards given in section
1.3. before reading this section.
4.1 Admitted surrounding conditions
Position the machine as established when the order was placed. Failing this the Manufacturer is not liable for any
inconveniences that may possibly arise.
Unless pointed out otherwise when placing the order, the compressor must work regularly in the surrounding conditions
indicated below:
ROOM TEMPERATURE
For a good work, the room temperature must not be lower than 5°C or higher than 40°C.
If the compressor works at a room temperature lower than the minimum value, the condensate could be separated
within the circuit and therefore the water would mix with the oil, thus deteriorating the quality of the latter, failing to
guarantee the even formation of the lubricating film between the moving parts with the possibility of seizure.
If the compressor works at a room temperature higher than maximum value, the compressor would take in air that is
too hot, which would prevent the heat exchanger from adequately cooling the oil in the circuit, raising the working
temperature of the machine, thus causing the thermal safety device to trip, which stops the compressor due to an
excessive temperature of the air/oil mixture at the screw outlet.
The maximum temperature of the room is to be measured while the compressor is running.
LIGHTING
The compressor has been designed in compliance with legal prescriptions and in the attempt to minimise shadow
zones to facilitate the operator’s job.
The lighting system of the factory is to be considered as crucial for the operat
or’s safety.
The room in which the compressor is installed must have no shadow zones, dazzling lights or stroboscopic effects due
to the lighting.
ATMOSPHERE WITH RISK OF EXPLOSION AND/OR FIRE
The standard compressor is not pre-arranged or designed to work in rooms subject to the risk of explosion or fire. The
performance of the compressor may decrease at the maximum permitted ambient temperature, with relative humidity
higher than 80% and at an altitude of more than 1,000 mt.
4.2 Space required for maintenance
The compressor must be installed in a large room that is well-aired, dust-free and sheltered away from rain and frost.
The compressor takes in a large amount of air that is required to ventilate it internally. A dusty atmosphere would in
time cause damages and inefficient performance.
Part of the dust once inside is taken in by the air filter causing it to clog rapidly and another part of dust will settle on the
components and will be blown against the cooling radiator, consequently compromising the efficiency of the heat
exchanger. It is therefore obvious that the cleanliness of the area in which the compressor is installed is crucial for the
correct efficiency of the machine, avoiding excessive running and maintenance costs. To facilitate maintenance jobs
and to create a favourable circulation of air, the compressor must have a sufficient free space all around it (see
par.3.2).
The room must be provided with outlets that lead outdoors near the floor and ceiling that will allow the natural
circulation of air.
If this is not possible, install some fans or extractors that guarantee a higher air flow rate than 50% that taken in by the
compressor. Min. flow m3/h 2500.
Ducts for the inlet and outlet of the air can be used in unfavourable environments. These ducts must be the same size
as the in-take and delivery grid. If these ducts are longer than 3 meters contact the
Authorised Service Centre .
Note! A conveyance system can be fitted to recover the hot ventilation air delivered, which can be used to heat the
room or for other purposes. It is crucial that the cross section of the system that recovers the hot air is
greater than the total cross section of the grid slots plus the system must be equipped with a forced extraction
system (extractor fan) to favour a constant downflow (min. sect. cm² 1200).
4.3 Positioning the compressor
The compressor must be placed on a flat floor. Check the position before placement.
The machine does not need a foundation or of any specific preparation of the supporting surface.
Do not secure the compressor rigidly to the floor.
