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
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 connecting the counterfl anges (see
par. 8.6 appendix).
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 obliga-
tion 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
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 neces-
sary 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 installa-
tions 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. 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.
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 conden-
sate in conformity with current local environmental regulations.
