ECO Line Compressors Instruction Manual
Description of the compressor and its component parts
The equipment is an oil-less compressor designed
to supply compressed air for dental and/or medical
applications.
Exploiting the rotation of the crankshaft, the pistons draw in air from the place where the
compressor is installed via the air-intake lter, pressurise it, and transfer it to the air receiver
for storage.
This operation is regulated by a pressure switch, which is typically set at between
6bar and 8.5 bar; the process is ultimately controlled by the safety valve: if the pressure
switch malfunctions and the air receiver pressure exceeds the safety valve setting, the valve
will crack open to vent the overpressure and eliminate the risk of bursting.
Class I appliance in relation to the new medical devices regulation (MDR) 2017/745
The product is not designed to withstand immersion in liquid (IPX0)

CAUTION
In zones with noise level > 85 dB, the operator must use suitable
personal protective equipment such as ear defenders or ear plugs.
Noise level values
A-weighted equivalent sound pressure below 80 dB (A)
C-weighted maximum instantaneous sound pressure < 130 dB
K correction factor
The stated noise values are emission levels and are not necessarily safe operating levels.
Even though there is a relationship between emission levels and exposure levels, this cannot
be used to reliably establish the need for further precautions.
The factors that determine the noise levels to which the workforce is exposed include duration
of exposure, workplace characteristics, other noise sources, etc.
Legally allowed exposure levels may vary from country to country.
In any case, this information will allow the compressor user to better assess the noise hazard
and risk.
Operating and environmental conditions - permissible limits
Although the compressor is designed for use only indoors, cabinet enclosed versions can also
be installed outdoors.
In order to ensure trouble-free operation in conditions of complete safety, the following
parameters must be observed:
Operating temperature: 0 °C to +40 °C
Maximum relative humidity: 80% for temperatures above 31 °C falling to 50% for
temperatures above 40 °C.
Power supply tolerance: +/- 10%

All compressors are shipped on a pallet that can be handled by a forklift or pallet truck.
Except for the smallest models, all other compressors must be moved using suitable
handling equipment.
Take care during handling, lifting and transport to prevent damage to the compressor or
other property and personal injury.
Check the weight of the compressor and use a forklift truck or suitable lifting equipment.
When lifting the compressor use caution to avoid damage.
While transporting the compressor lash securely it to the vehicle both crosswise and
lengthwise.
Packs of the same weight can be stacked up to three high.
Unpacking
Remove the compressor from the pack carefully.
Keep the pack for possible future shipping requirements.
If the pack shows signs of damage, sign the shipping agent's delivery note
under reservation and keep the pack for possible inspection by the transport
company.
If you need to contact the distributor or the manufacturer, always quote the
compressor serial number to aid rapid identication.
The equipment serial number is always transcribed on the transport document.
Assembly
Install the compressor indoors or anyway in a place where it is not directly exposed to the
weather.
The room in which the compressor is installed must be well ventilated and not damp;
if the compressor is installed in a plant room air circulation must be su󰀩cient for all the
equipment installed; ambient temperature must be no higher than 40°C and no lower than
0°C.
The product feet are tted with rubber vacuum cups. These are essential because they
reduce vibration and thus help to reduce the noise level while also limiting any movement of
the unit while it is running.

This manual is the property of . No part of it may be reproduced in any form.
ECO Line Compressors Instruction Manual
Most models are equipped with handles so they can be safely lifted.
The compressor should be installed in a clean environment.
We recommend creating the compressed air circuit with a classic “ring” type circuit
using Rilsan Pa12 tubing (or an equivalent type of plastic compressed air tubing);
specically:
Main line: Ext. D 18 mm
Secondary line / connection between ring and dental chair: Ext. D 14 mm
Electrical connection
The main connections must be made by specialized technicians. To guarantee correct
installation, check the current and voltage value of the building electrical supply. Connecting
the compressor to an electrical supply with the incorrect voltage can cause serious damage.
CAUTION
Do not replace the electrical power cable if not expressly authorised by the supplier
or by an authorised installer: replacing the cable could lead to interference with other
nearby equipment and/or faults.
Beware of the risk of electric shock!
Disconnect the power at the main disconnect switch before connecting the compressor.
Install the equipment in a place where it cannot come into contact with water or other
liquids.
Make sure the electrical power line is su󰀩cient for the compressor, following the data shown
on the motor rating plate.
Failure to comply with these instructions could lead to death, re, or
electrocution.
