
The machine must be protected from atmospheric agents and not directly exposed to sun light.

A seating base flat and capable to hold the weight of the machine.

Ambient temperature complying with the nominal data of the dryer.

A clean, dry and without forced draft (we suggest to blow the warm air outside the installation site).

Make sure to leave sufficient clearance around the dryer (20 inches, 500 mm) in order to allow an
adequate cooling of the machine and for maintenance and/or control operations.
The incoming air must be free from smoke or flammable vapours which could lead to explosion or fire
risks.
2.3 UNPACKING
The packaging is made of carton or of cellophane. We recommend that you keep the original packaging for the device
in case it has to be transported to another location or sent to a service center. Dispose the various packaging
materials in compliance with the relevant rules locally in force.

unpack the device, removing the strapping from the carton. Always wear safety gloves when using scissors or
other tools to cut the straps or the cellophane;

remove the carton or the cellophane;

in case it’s necessary another handling of the device, refer to section 2.1;

2.4 INSTALLATION
Before attempting any installation operation, make sure that

No part of system is under pressure.

No part of the system is electrically powered.

The pipes to be connected to the dryer does not weigh on the device.

Tubing to be connected to the dryer are impurities free.

All interconnecting piping has been tightened.
After having verified the points listed above, you can proceed to the installation of the machine.
1. Connect the dryer to the compressed air lines indicated in the diagrams below. If not already
existing, we suggest to install a by-pass allowing to insulate the machine from the plant, thus to
facilitate eventual maintenance operations.
2. Perform the electrical connection in accordance with any local laws and regulations after reviewing
the dryer electrical specifications and wiring diagram.
3. Check the condensate drainage assembly, and connect the drain flexible hose to the draining line,
keeping in mind that the condensate separated by the dryer contains oil particles, therefore,
in order to dispose it in compliance with the local rules in force, we suggest a water-oil
separator having adequate capacity.
4. Power the dryer after having checked that the nominal voltage and line frequency are constant
and matching the nominal values of the machine. The user must provide the installation with
an adequate line protection and a ground terminal complying with the electrical rules
locally in force.
