Parker Polestar smart PSE 120 Manual De Uso página 25

2 Introduction
This manual is in reference to refrigeration dryers designed to remove water vapor from compressed
air.
2.1 Transportation
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
• All the units are assembled, wired, charged with refrigerant and oil and tested under standard
operating conditions in the factory;
• on receiving the machine check its condition: immediately notify the transport company in case of
any damage;
• 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
Install indoors in a clean, dry area that is protected from the elements, direct sunlight and/or
other harsh conditions.
!
The product installed must be suitably protected against fi re risk (Ref. EN378-3).
3.1 Procedures
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 connections.
3.2 Operating space
Y
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 Condenser version
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 compressor, 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 opening 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.
