1.3 WARNINGS
1.4 PROPER USE OF THE
DRYER
This dryer has been designed, manufactured and
tested only to be used to separate the humidity
normally contained in compressed air. Any other use
has to be considered improper. The Manufacturer
will not be responsible for any problem arising from
improper use; the user will be in any case
responsible for any resulting damage.
Moreover, the correct use requires the compliance
with the installation conditions, in particular:
• Voltage and frequency of the primary elec-
trical supply.
• Pressure, temperature and flow-rate of the
incoming air.
• Ambient temperature.
This dryer is supplied tested and fully assembled.
The only operation left to the user is the installation of
the desiccant into the dryer towers and the
connection to the plant in compliance with the
instructions given in the following chapters.
The purpose of the machine is the
separation of water present in
compressed air. The dried air cannot be
used for respiration purposes or for
operations leading to direct contact with foodstuff,
unless subject to further treatments.
Compressed air is a highly hazardous energy source. Never work on the dryer with
parts under pressure. Never point the compressed air or the condensate drain jet
towards anybody.
The user is responsible for the installation of the dryer, which has to be executed on the
basis of the instructions given in the “Installation” chapter. Otherwise, the warranty will
be voided and dangerous situations for the personnel and/or damages to the machine
could occur.
Only qualified personnel can use and service electrically powered devices. Before
attempting any maintenance action, the following conditions must be satisfied :
• Ensure that any part of the machine is under voltage and that it can-
not be connected to the mains.
• Ensure that any part of the dryer is under pressure and that it cannot
be connected to the compressed air system.
Any change to the machine or to the relevant operating parameters, if not previously
verified and authorised by the Manufacturer, in addition to create the possibility of
dangerous conditions it will void the warranty.
Don’t use water to extinguish fire on the dryer or in the surrounding area.
