3.3 Tips
To prevent damage to the internal parts of the dryer and air com-
pressor, avoid installations where the surrounding air contains
solid and/or gaseous pollutants (e.g. sulphur, ammonia, chlorine
and installations in marine environments).
3.4 Electrical connection
Use approved cable in conformity with the local laws and regula-
tions (for minimum cable section, see par. 8.3).
Install a differential thermal magnetic circuit breaker with
contact opening distance ² 0.12 inches (3 mm) ahead of the sys-
tem (IDn = 0.3A) (see the relevant current local regulations).
3.5 Condensate drain connection
The dryer is supplied either with a float drain, a timed drain or an
electronic level sensing drain.
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 sup-
plied with the dryer for specific details concerning the condensate
drain.
Y
Make the connection to the draining system, avoiding con-
nection in a closed circuit shared by other pressurized discharge
lines. Check the correct flow of condensate discharges. Dispose
of all the condensate in conformity with current local environ-
mental regulations.
4 Commissioning
4.1 Preliminary checks
Before commissioning the dryer, make sure:
a) installation was carried out according that given in the section
3;
b) the air inlet valves are closed and that there is no air flow
through the dryer;
c) the power supply is correct;
4.2 Starting
a) Start the dryer before the air compressor by means of the
14
main power switch ; the power lamp will illuminate
(green);
b) after at least 5 minutes slowly open the air inlet valve and
subsequently 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 compres-
sor is working;
b) the dryer operates in automatic mode, therefore field settings
are not required;
c) in the event of unforeseen excess air flows, by--- pass to avoid
overloading the dryer;
4.4 Stop
a) Stop the dryer 2 minutes after the air compressor stops or in
any case after interruption of the air flow;
b) do not allow compressed air to flow through the dryer when
the latter is not running;
14
c) switch off at the main power switch
out and the compressor stops.
