11.2.1 Timed condensate discharge system
The timed condensate discharge system must be carefully checked and serviced in order to prevent the separated condensate
from being entrained with the flow of compressed air into the distribution system.
11.2.1.1 Filter cleaning
The filter should be cleaned every month and in certain cases more frequently.
All models are equipped with a shut-off valve with integral filter and solenoid valve (see figures below).
After re-opening the shut-off valve, power on the unit again and restart it.
11.2.1.2 Solenoid valve maintenance
11.2.2 Smart condensate discharge system
The smart condensate discharge system is supplied pre-installed in the unit.
Instructions concerning operation and maintenance of the intelligent condensate discharge unit are given in the discharge unit
handbook, which is attached to this manual.
•
Open the line circuit breaker to disconnect the
power supply to the dryer.
•
To remove the metal strainer [3] simply close
the shut-off valve.
•
Press the manual condensate discharge
button
to check that the filter is not
pressurized.
•
Carefully unscrew filter cap [1] retaining
gasket [2] and remove strainer mesh [3].
•
Once cleaned, refit the strainer making sure it
is correctly seated and refit cap [1].
•
Renew the O-ring [2] if it is damaged.

If any particles are not captured by the filter and
consequently cause the valve to malfunction, all the valve’s
internal components must be cleaned.
Proceed as follows:
•
isolate and depressurize the dryer;
•
open the line switch to disconnect the power
supply to the dryer;
•
undo the screw in the centre of the valve
power supply connector cap;
•
lift up and remove the cap;
•
remove the solenoid valve from the pipe and
tightly clamp the body in a vice;
•
unscrew the nut [1] fixing the solenoid valve
[2] and remove it from shaft [3];
•
unscrew the shaft from the valve seat;
check the condition of the black O-ring [4] and
of all other components and clean them
carefully;
•
re-assemble the components by reversing the
above procedures;
•
make sure that the valve is re-installed with
the arrows on the body pointing in the right
direction.

ATTENTION
Take care not to overtighten the nut [1] as this could obstruct movement of the valve element and prevent the valve
from opening and closing correctly.
