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 cannot 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.
These refrigeration air dryers contain R134.a & R404A HFC type refrigerant fluid, not considered
potential ozone depleting. Maintenance on refrigeration systems must be carried out only by
refrigeration engineers according to local rules.
R134.a & R404A may be dangerous for men only if it is present in bulk concentrations. In case of
leaks the room is to be aired before any intervention.
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 will void
the warranty.
Don't use water to extinguish fire on the dryer or in the surrounding area.
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 mains.
• Pressure, temperature and flow-rate of the incoming air.
• Pressure, temperature and cooling water capacity (Water-Cooled).
• Ambient temperature.
This dryer is supplied tested and fully assembled. The only operation left to the user is 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 and eventual oil particles present in
compressed air. The dried air cannot be used for breathing purposes or for operations leading to
direct contact with foodstuff.
This dryer is not suitable for the treatment of dirty air or of air containing solid particles.
