ADDRESSES OF ASSISTANCE CENTRES
In the event of breakdown or malfunction of the dryer, switch it off and do not tamper with it. If repairs are needed,
contact your dealer or the manufacture for an approved service contact and insist on the use of original spare parts.
Failure to comply with the above may impact the safety and operation of the machine.
INTRODUCTION
Keep this manual for future consultation; the use and maintenance manual is an integral part on the dryer.
Read this manual carefully before carrying out any operations on the dryer.
The installation of the dryer and all operations involving it must be performed in conformity all the regulations in
force concerning electronics and refrigerant circuit and personal safety.
CHARACTERISTICS AND SAFETY PRECAUTIONS
BEFORE REMOVING THE PROTECTIVE GUARDS TO CARRY OUT ANY MAINTENANCE ON THE MACHINE, SWITCH OFF THE ELECTRIC
POWER SUPPLY AND DISCHARGE THE RESIDUAL PRESSURE INSIDE THE UNIT.

PERSONNEL.
The manufacturer does not accept responsibility for damage caused as a result of negligence of failure to abide by the
instructions given above.
THIS MACHINE IS NOT SUITABLE FOR OUTDOOR INSTALLATION
THIS MACHINE CORRESPONDS TO THE ESSENTIAL SAFETY REQUIREMENTS FORESEEN FROM THE
EUROPEAN STANDARD (2006/42 CE).

1.0 GENERAL CHARACTERISTICS
The dryer is a chilling machine with direct expansion heat exchanger and dry evaporator.
The air to be dried is sent to the heat exchanger in which the water vapor present is condensed: the condensate gathers
in the separator and is discharged outside through an electronic level sensing drain..
2.0 INTENDED USE
The dryer has been designed and built to dry compressed air for industrial use. The dryer cannot be used in premises
where there is a risk of fire or explosion or where work is carried out which releases substances into the environment
which are dangerous with regard to safety (for example: solvents, inflammable vapours, alcohol, etc.).
In particular the appliance cannot be used to produce air to be breathed by humans or used on direct contact with
foodstuffs. These uses are only allowed if the compressed air is additionally treated by means of a suitable purification
system
(Consult the manufacturer for these special uses.)
This appliance must be used only for the purpose for which it was specifically designed. All other uses are to be
considered incorrect and therefore unreasonable. The Manufacturer cannot be held responsible for any damage resulting
from improper, incorrect, or unreasonable use.
3.0 OPERATION
The hot gaseous refrigerant leaves the evaporator (4) and enters the refrigeration compressor (1) where it is compressed
and pumped into the condenser (2). With the aid of a cooling fan (3) the refrigerant is condensed into a liquid. The
condensed liquid refrigerant then passes through a filter/dryer (8) to remove any residual moisture. A capillary tube (7) is
used as an expansion device before the refrigerant re-enters the evaporator (4). The expansion and evaporation of the
refrigerant produces a cooling effect. Due to the heat exchange with the compressed air passing through the heat
exchanger, the air temperature is reduced causing water vapour to condense out of the air stream. The water is
removed in a water separator (5) so that it can be evacuated though the automatic level drain (13). The now gaseous
refrigerant is returned to the compressor (1) where the cycle repeats.
The circuit is equipped with a hot gas bypass (HGBP) system for the refrigerant which adjusts the available refrigerating
capacity to the actual cooling load. This is achieved by injecting hot gas under the control of the HGBP valve (9) to
maintain a constant refrigerant pressure in the evaporator. With this control the of the refrigeration pressure the
temperature never decreases below (32°F / 0°C).

4.0 GENERAL SAFETY STANDARD
The appliance may be used only by specially trained and authorized personnel.
Any tampering with the machine or alterations not approved beforehand by the Manufacturer relieve the latter of
responsibility for any damage resulting from the above actions.
The removal of or tampering with the safety devices constitutes a violation of the European Standards on safety.
ALL WORK ON THE ELECTRONICS AND REFRIGERANT CIRCUIT, HOWEVER SLIGHT, MUST BE CARRIED OUT BY PROFESSIONALLY
SKILLED PERSONNEL.

9.0 INSTALLATION LOCATION
9.1 FLOOR
The floor must be level and be of a type that can suitably support the total weight of the machine as shown in Fig. 5
Remember the total weight of the machine when positioning it.
9.2 VENTILATION
The choice of an appropriate room will prolong the life of your dryer; the room must be spacious, dry, well ventilated and
free from dust.
The operating conditions to be complied with are the following:
Min. room temperature:
41 °F
(
5
°C
)
(compulsory
)
Min. inlet allowed temperature:
37,4 °F
(
3 °C
)
Max. room temperature:
113 °F
(
45 °C
)
(compulsory)
Max. inlet allowed temperature:
131 °F
(
55 °C
)
Max. temperature of inco
ming air:
131 °F
(
55 °C
)
Max. wor
king pressure:

(
14 bar
)
 Please keep environmental conditions stable (temperature and humidity) in order to avoid refrigerant compressor/fan
overload and/or reduction of dryer performance. Similar failures shall affect warranty reimbursements.
 Please ensure the appropriate composition of the air within the machine room: - clean with no damaging contaminants
(e.g., dust, fibers, fine sand) - free of explosive or chemically unstable gases or vapors - free of acid/alkaline forming
substances, particularly ammonia, chlorine or hydrogen sulfide. Similar failures shall affect warranty reimbursements.
Please note that we do not recommend the use of ducting for the cooling air on these units.

10.0 TRANSPORT AND HANDLING
The machine must be transported as shown in the following figures.
11.0 UNPACKING
CUTTING THE METAL STRAPPING CAN BE DANGEROUS, CUT PIECES SHOULD BE PROPERLY DISPOSED.
After removing the packing, ensure that the machine is unbroken and that there are no visibly damaged parts.
If you are in doubt, do not use the machine and contact your dealer or the manufacture for technical assistance.
The packing material (plastic bags, polystyrene foam, nails, screws, wood, metal strapping, etc.) must not be left within
the reach of children or left in the environment, as they are a potential source of danger and pollution.Dispose of these
materials in the approved collection centers.

12.0 INSTALLATION
12.1 POSITIONING
After unpacking the equipment and preparing the installation location, put the machine into position, checking the
following items:
ensure that there is sufficient space around the machine to allow maintenance (see Fig. 6).
ENSURE THAT THE OPERATOR CAN SEE THE WHOLE MACHINE FROM THE CONTROL PANEL AND CHECK THE PRESENCE OF ANY
UNAUTHORIZED PERSONS IN THE VICINITY OF THE MACHINE.
12.2 ELECTRICAL CONNECTION
Check that the supply voltage is the same as the value indicated on the machine data plate.
Check the condition of the line leads and ensure that there is an a sufficient grounding line.
 Ensure that there is a fused disconnect or appropriately sized breaker to protect the machine against over-
currents, Ref. 1 Fig. 6. For details (size and type) see wiring/service diagram.
ONLY PROFESSIONALLY LICENSED PERSONNEL SHOULD ACCESS TO THE ELECTRIC PANEL. SWITCH OFF THE POWER BEFORE
OPENING THE DOOR OF THE ELECTRIC PANEL. COMPLIANCE WITH THE REGULATIONS IN FORCE CONCERNING ELECTRICAL
WORK IS FUNDAMENTAL FOR OPERATOR SAFETY AND FOR THE PROTECTION OF THE MACHINE.
12.3 CONNECTION TO THE COMPRESSED AIR NETWORK
Install isolation valves (not supplied) Ref. 1 between the machine and the compressed air network so that the dryer may
be isolated during maintenance operations (see figure 7 ).
Plumb the condensate auto-drain, Ref. (2) Fig. 7, to a location where it can be treated prior to disposal.
Condensate must be disposed of according to the local rules and regulations in the location of the installation.
All refrigerant dryers shall be equipped with proper pre-filter at closest position to dryer air inlet. The filter should be
replaced annually or sooner for installations with high contaminate levels or ambient humidity.
ALL DAMAGE DUE TO THE FAILURE TO COMPLY WITH THESE NDICATIONS CANNOT BE ATTRIBUTED TO THE MANUFACTURER AND
MAY LEAD TO VOIDING OF THE MACHINE WARRANTY.
