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).
!
The product installed must be suitably protected against fi re risk
(Ref. EN378-3).
Y
Comply with the instructions given in par. 9.2 and 9.3.
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.
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.
PSE 120-350
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 to be avoided 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. 9.3).
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.
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
4.1 Preliminary checks
Before commissioning the dryer, make sure:
• installation was carried out according that given in the section 3;
• the air inlet valves are closed and that there is no air fl ow through the
dryer;
• the power supply is correct;
• with Wc version, open the cooling water circuit a few minutes before
<50 ppm starting the dryer.
4.2 Starting
70-150 ppm
a) Start the dryer before the air compressor;
<0.1 ppm
!
THE CRANKCASE HEATER MUST BE SWITCHED ON 12 HOURS
<0.2 ppm
BEFORE STARTING THE DRYER.
<2 ppm
b) switch the power on by turning the MAIN SWITCH "
"I ON": the dryer is powered and the word "OFF" appears on the dis-
70-300 ppm
play.
set
c) Press to start (for model 120-180).
<0.05 ppm
Press to start (for model 220-180).
Y
<5 ppm Fan (Ac version): if connected with the wrong phase sequence they
turn in the opposite direction, with the risk of being damaged (in this
<0.2 ppm
case the air exits the dryer cabinet from the condenser grilles instead
from the fan grille - see par. 9.8 for correct air fl ow); immediately invert
two phases.
d) Wait 5 minutes, then slowly open the air inlet valve;
e) slowly open the air outlet valve: the dryer is now drying.
Phases Monitor
If appears to display an alarm, during the start up of the dryer, the user
must verify the wiring of the input terminals of the disconnecting switch
of the dryer.
4.3 Operation
• Leave the dryer on during the entire period the air compressor is work-
ing;
• The dryer operates in automatic mode, therefore fi eld settings are not
required;
• In the event of unforeseen excess air fl ows, by-pass to avoid
overloading the dryer.
• Avoid air inlet temperature fl uctuations.
4.4 Stop
a) Stop the dryer 2 minutes after the air compressor stops or in any
case after interruption of the air fl ow;
b) make sure compressed air does not enter the dryer when the dryer is
disconnected or if an alarm occurs.
