2 Introduction
This manual refers to refrigeration dryers designed to guarantee high
quality in the treatment of compressed air.
2.1 Transport
The packed unit must:
• remain upright;
• be protected against atmospheric agents;
• be protected against impacts.
2.2 Handling
Use a fork-lift truck suitable for the weight to be lifted, avoiding any type
of impact.
2.3 Inspection
a) All the units are assembled, wired, charged with refrigerant and oil
and tested under standard operating conditions in the factory;
b) on receiving the machine check its condition: immediately notify the
transport company in case of any damage;
c) unpack the unit as close as possible to the place of installation.
2.4 Storage
If several units have to stacked, follow the notes given on the packing.
Keep the unit packed in a clean place protected from damp and bad
weather.
3 Installation
Y
For the correct application of the warranty terms, follow the instruc-
tions given in the start-up report, fi ll it in and send it back to Seller.
In places with fi re hazard, provide for a suitable fi re-extinguishing sys-
tem.
3.1 Procedures
Install the dryer inside, in a clean area protected from direct atmospheric
agents (including sunlight).
!
Make sure to screw down the stud bolts in the fl anges before con-
necting the counterfl anges (see par. 8.6).
Y
Comply with the instructions given in par. 8.2 and 8.3.
All dryers must be fi tted with adequate pre-fi ltration near the dryer air
inlet. Seller is excluded any obligation of compensation or refund for any
direct or indirect damage caused by its absence
Y
Pre-fi lter element (for 3 micron fi ltration or better) must be replaced
at least once a year, or sooner as per manufacturer recommendations.
Y
Correctly connect the dryer to the compressed air inlet/outlet con-
nections.
PSE 460-1800
3.2 Operating space
Leave a space of 1.5 m around the unit.
Leave a space of 2 m above dryer models with vertical condensation air
expulsion.
3.3 Versions
Air-cooled version (Ac)
Do not create cooling air recirculation situations. Do not obstruct the
ventilation grilles.
Water-cooled version (Wc)
If not provided in the supply, fi t a mesh fi lter on the condensation water
inlet.

Please note that for special cooling water types such as demineralized,
deionized or distilled it is necessary to contact the manufacturer to verify
which kind of condenser should be used since the standard material may
not be suitable.
3.4 Tips
To prevent damage to the internal parts of the dryer and air compres-
sor, avoid installations where the surrounding air contains solid and/or
gaseous pollutants (e.g. sulphur, ammonia, chlorine and installations in
marine environments).
The ducting of extracted air is not recommended for versions with axial
fans.
3.5 Electrical connection
Use approved cable in conformity with the local laws and regulations (for
minimum cable section, see par. 8.3).
Install a differential thermal magnetic circuit breaker with contact open-
ing distance 3 mm ahead of the system (RCCB - IDn = 0.3A) (see the
relevant current local regulations).
The nominal current In of the magnetic circuit breaker must be equal to
the FLA with an intervention curve type D.
Select the power supply and insert a
bridge as shown below:
S7-S6 for 400/3/50
S8-S6 for 460/3/60
Inside the electrical panel there is an
instruction label.
3.6 Condensate drain connection
Y
Make the connection to the draining system, avoiding connection in
a closed circuit shared by other pressurized discharge lines. Check the
correct fl ow of condensate discharges. Dispose of all the condensate in
conformity with current local environmental regulations.

4 Commissioning
<0.1 ppm
4.1 Preliminary checks
<0.2 ppm
Before commissioning the dryer, make sure:
• installation was carried out according that given in the section 3;
<2 ppm
• the air inlet valves are closed and that there is no air fl ow through the
dryer;
70-300 ppm
• the power supply is correct;
• with Wc version, open the cooling water circuit a few minutes before
starting the dryer.
<0.05 ppm
4.2 Starting
a) Start the dryer before the air compressor;
<5 ppm

THE CRANKCASE HEATER MUST BE SWITCHED ON 12
<0.2 ppm
HOURS BEFORE STARTING THE DRYER.
