Connection to the cooling water network (Water-Cooled)
DANGER!
Compressed air!
All works must only be carried out by qualified skilled personnel.
Never work on compressed-air systems which are under pressure.
The operator or the user must ensure that the dryer is never operated with a pressure exceeding the
maximum pressure value indicated on the name plate.
Exceeding the maximum operating pressure can be dangerous for the operator but also for the device.
The temperature and the amount of cooling water must comply with the limits indicated on the technical characteristics
chart. The cross section of the connection pipes, preferably flexible, must be free from rust, chips and other impurities.
We recommend to use connecting pipes able to insulate the dryer from possible vibrations originating from the line
(flexible hoses, vibration damping fittings, etc.).
NOTE
!
Contaminated intake water!
In the event that the intake water is strongly contaminated we recommend the additional installation of a
prefilter (500 micron), to avoid clogging of the heat exchanger.

– Pressure difference at dryer water connection points at maximum water flow - Other head pressure on
request.
CAUTION!
During the piping of the dryer, the inlet and outlet connections need to be supported as is shown in the
illustration.
Non-observance will cause damage.
8.8
Condensate drain
Danger
!
Compressed air and condensate under pressure!
The condensate is discharged at system pressure.
The drain pipe needs to be secured.
Never direct the condensate drain pipe at persons.
The dryer comes already fitted with an electronic condensate drainer.
Connect and properly fasten the condensate drain to a collecting plant or container.
The drain cannot be connected to pressurized systems.
Don’t dispose the condensate in the environment.
The condensate collected in the dryer contains oil particles released in the air by the compressor.
Dispose the condensate in compliance with the local rules.
We recommend to install a water-oil separator where to convey all the condensate drain coming from
compressors, dryers, tanks, filters, etc.
