SPE004-100

2 Introduction

is manual refers to refrigeration dryers designed to guarantee high

quality in the treatment of compressed air.

2.1 Transport

e 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 lift ed, 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

3.1 Procedures

Install the dryer inside, in a clean area protected from direct atmospher-
ic agents (including sunlight).

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

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.

Do not invert the compressed air inlet and outlet connections.

3.2 Operating space

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 compres-
sor, avoid installations where the surrounding air contains solid and/or
gaseous pollutants (e.g. sulphur, ammonia, chlorine and installations in
marine environments).
Th

e ducting of extracted air is not recommended 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 diff erential 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).
Th

e 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.

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.

4.2 Starting

a) Start the dryer before the air compressor by means of the main power

switch “

”, the display shows “DRY”

;

b) aft er at least 5 minutes slowly open the air inlet valve and subse-
quently open the air outlet valve: the dryer is now performing its air
drying function.

4.3 Operation

a)  Leave the dryer on during the entire period the air compressor is
working;
b)  the dryer operates in automatic mode, therefore fi eld settings are not
required;
c)  in the event of unforeseen excess air fl ows, by-pass to avoid overload-
ing the dryer.

4.4 Stop

a)  Stop the dryer 2 minutes aft er the air compressor stops or in any case
aft er interruption of the air fl ow;
b)  do not allow compressed air to fl ow through the dryer when the lat-
ter is not running;
c) switch off  at the main power switch
