2 Introduction
This manual is in reference to refrigeration dryers designed to remove wa-
ter 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. 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 connections.
3.2 Operating space
Y
Leave a space of 1.0 m around the unit.
3.3 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.
3.4 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 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.
3.5 Condensate drain connection
If a timed or electronic unloader is installed, use terminals CN (R1-S1)" (see par. 8.8).
For timed and electronic drains: refer to separate manual supplied with the dryer for specifi c details
concerning the condensate drain.
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.
Y
The drain cannot be left unconnected, and needs to be connected to ensure the waste is drai-
ned into an appropriate site drain system in accordance with local regulations.
